Cancer remains a leading cause of mortality across the globe and Nigeria is no exception: Breast, cervical, prostate, and liver malignancies are climbing steadily despite wider access to chemotherapy, radiotherapy, and targeted drugs. 



For many patients, however, modern treatment is difficult to afford. This has sparked renewed interest in a largely untapped yet promising resource: Nigeria’s indigenous food plants.



These plants - including their leaves, seeds, tubers, and fruits - are loaded with bioactive compounds. Laboratory studies show that many of these natural substances have the potential to <a href="https://www.earth.com/news/many-plant-species-show-great-promise-in-fight-against-cancer/" target="_blank" rel="noreferrer noopener">slow or even halt</a> tumor growth. 



A growing body of evidence suggests that these plants, long consumed as part of the traditional diet, could be developed as low-cost, complementary tools in the nation’s fight against cancer.



<h2 class="wp-block-heading" id="h-plants-that-prevent-or-halt-cancer">Plants that prevent or halt cancer</h2>



Researchers have catalogued dozens of edible Nigerian species with measurable <a href="https://www.earth.com/news/ai-is-the-next-frontier-in-cancer-treatment/" target="_blank" rel="noreferrer noopener">anti-cancer activity</a>, but nine stand out for the breadth of experimental data already available.



Spondias mombin (hog plum) contains the flavonoid quercetin along with carotenoids that trigger apoptosis - the “self-destruct” program in malignant cells - while simultaneously tamping down inflammation.



Xanthosoma sagittifolium, a cocoyam cultivated widely in the humid south, produces tannins and other phenolics that cause leukemia cells to stall in the cell-cycle, blocking proliferation and reducing the formation of new blood vessels that tumors need in order to expand.



Oil palm (Elaeis guineensis) is often maligned for ecological reasons, yet its vitamin-E–rich tocotrienols are potent antioxidants; in <a href="https://www.earth.com/news/plant-based-diet-improves-health-in-women-with-breast-cancer/" target="_blank" rel="noreferrer noopener">breast cancer</a> models they lower cell viability and force cells into arrest, nudging them toward death.



Irvingia gabonensis, the African bush mango, supplies gallotannins that regulate metabolic pathways linked to tumorigenesis and stimulate immune surveillance.



<h2 class="wp-block-heading" id="h-powerful-cancer-fighting-plant-compounds">Powerful cancer-fighting plant compounds </h2>



Allium cepa, the humble onion, is packed with organosulphur compounds as well as flavonoids that up-regulate detoxification enzymes, mop up DNA-damaging free radicals and may even help reverse multidrug resistance.



Blighia sapida (ackee) fruit, famous for its culinary role in Caribbean cuisine, also grows in Nigeria; laboratory work shows its flavonoids can hamper the ERK5 pathway, a key driver of aggressive breast cancer.



Dioscorea dumetorum, a wild yam, synthesizes diosgenin - long prized in the pharmaceutical industry as a raw material for steroid hormones - which shuts off the pro-survival NF-κB and MAPK cascades in cancer cells.

Psidium guajava (guava) leaves have been used for generations to treat diarrhea; now their tannins and phenolic acids are recognized for inducing apoptosis and shielding DNA from oxidative injury.



Finally, Talinum triangulare, the protein-rich “waterleaf,” contains quercetin and other antioxidants that bolster immune responses and hinder tumor growth in vitro.



<h2 class="wp-block-heading" id="h-diverse-plants-with-similar-strategies">Diverse plants with similar strategies </h2>



Despite their botanical diversity, these species rely on a handful of overlapping biochemical strategies. 



First and foremost is apoptosis induction: they activate pro-apoptotic proteins such as Bax while down-regulating anti-apoptotic factors like Bcl-2, tipping the balance toward cell death.



Many extracts also impose cell-cycle arrest at the G1/S or G2/M checkpoints by interfering with cyclin-dependent kinases; deprived of the green light to divide, cancer cells accumulate DNA damage and succumb. Angiogenesis - the sprouting of new blood vessels that feed a tumor - is another frequent target. 



Compounds from cocoyam, yam and hog plum have been shown to lower levels of vascular endothelial growth factor (VEGF) and related signals, choking off the nutrient supply to nascent tumors. 



Inflammatory enzymes (COX-2, iNOS) and reactive oxygen species are suppressed as well, reducing the chronic <a href="https://www.earth.com/news/fasting-helps-the-body-fight-inflammation-and-chronic-diseases/" target="_blank" rel="noreferrer noopener">inflammation</a> and oxidative stress that often initiate or accelerate malignancy.



<h2 class="wp-block-heading" id="h-bridging-tradition-and-modern-oncology"><a></a>Bridging tradition and modern oncology</h2>



While pre-clinical data are encouraging, several hurdles must be cleared before Nigerian food plants can take their place beside paclitaxel or cisplatin. 



Bioactive composition varies by soil type, rainfall pattern and harvest time; rigorous agronomic studies are needed to standardize cultivation and extraction.



Dosage, toxicity and potential interactions with conventional drugs remain largely untested in humans. Well-designed clinical trials - randomized, placebo-controlled and sufficiently powered - are essential if these botanicals are to earn a formal role in oncology clinics. 



Another challenge is the disconnect between traditional knowledge holders and laboratory scientists.



Ethnobotanical surveys can help bridge that gap, ensuring that leads chosen for development reflect community practices and dietary realities. 



Public-health campaigns, meanwhile, could educate physicians, pharmacists, and patients about the evidence base for plant-derived adjuncts, avoiding unsubstantiated claims while highlighting genuine benefits such as reduced side-effects or improved <a href="https://www.earth.com/news/active-aging-physical-activity-has-a-direct-impact-on-life-quality/" target="_blank" rel="noreferrer noopener">quality of life</a>.



<h2 class="wp-block-heading" id="h-cost-effective-renewable-treatments">Cost-effective, renewable treatments</h2>



If these hurdles are overcome, the payoff could be substantial. Many of the plants grow wild or are already farmed for food, implying a local, renewable supply chain. 



Extracts could be formulated as teas, capsules or functional foods, lowering barriers to access in rural areas where oncology centers are scarce.



Combining plant-based agents with lower doses of chemotherapy or radiation might retain efficacy while mitigating nausea, hair loss, and myelosuppression - side-effects that often deter patients from completing treatment.



<h2 class="wp-block-heading" id="h-fighting-cancer-with-plants-future-research">Fighting cancer with plants: Future research</h2>



Future research should prioritize mapping the full chemoprofile of each candidate plant. This should also include identifying synergistic combinations and unravelling pharmacokinetics in vivo. 



Genomic and metabolomic tools can accelerate the discovery of lead molecules, while <a href="https://www.earth.com/news/how-nanotechnology-is-fighting-microplastic-pollution/" target="_blank" rel="noreferrer noopener">nanotechnology</a> may enhance their bioavailability. Collaboration between Nigerian universities, pharmaceutical firms, and international cancer institutes will be vital to secure funding and regulatory approval.



Ultimately, Nigeria’s indigenous food plants harbor a rich arsenal of anticancer phytochemicals that attack tumours through multiple, complementary pathways. 



Integrated with evidence-based medicine, these botanicals could broaden the therapeutic arsenal, reduce treatment costs and bring culturally familiar options to patients. Harnessing the plants may demand careful science, but the potential rewards will justify the effort.



The study is published in the journal <a href="https://www.xiahepublishing.com/2835-6357/FIM-2024-00042" target="_blank" rel="noreferrer noopener">Future Integrative Medicine</a>.

Truffles have long captivated the senses, with their tantalizing aroma and elusive nature keeping the culinary world on its toes. To the gastronome, they are an exotic culinary delight; to the mycologist, they present an intriguing species subject of study.



Now, this enigmatic world has become even more fascinating with the discovery of two new truffle species, which add another layer of intrigue to the legacy.



<h2 class="wp-block-heading" id="h-species-found-by-truffle-dogs">Species found by truffle dogs</h2>



The discovery was led by two enthusiastic truffle <a href="https://www.earth.com/news/trained-dogs-can-sniff-out-invasive-pests-in-forests/" target="_blank" rel="noreferrer noopener">dogs</a>, Luca and Monza.



The find? A hitherto unknown pair of truffles, christened as Tuber canirevelatum and Tuber cumberlandense.



The former, aptly named the "dog-found" truffle, pays homage to the canine detectives and their tireless work. The latter derives its name from the Cumberland Plateau, where it was found.



Guiding the canine sleuths were citizen scientists Lois Martin and Margaret Townsend. After the initial discovery, and eager to unveil the mystery of their find, they reached out to the experts.



Michigan State University (<a href="https://msu.edu/" target="_blank" rel="noreferrer noopener">MSU</a>) and the <a href="https://www.ufl.edu/" target="_blank" rel="noreferrer noopener">University of Florida</a> became the primary research hubs.



<h2 class="wp-block-heading" id="h-unraveling-the-truffle-mystery">Unraveling the truffle mystery</h2>



At MSU, the Department of Plant, Soil and Microbial Sciences took the baton from the truffle dogs. 



The team, led by associate professor Gregory Bonito and undergraduate student Alassane Sow, used DNA analyses to identify the specimens and position them on the tree of life.



”Receiving these samples was very exciting, especially because they looked very similar to the well-known edible <a href="https://www.earth.com/news/climate-change-truffle-industry/" target="_blank" rel="noreferrer noopener">European truffles</a> Tuber macrosporum and Tuber aestivum,” said Sow.



“We hope that by describing both of these species there will be increased interest in cultivating North American truffles. Our analyses show that each has aromatic compounds found in some of the most valuable truffle species.”



<h2 class="wp-block-heading" id="h-truffles-a-culinary-goldmine">Truffles: A culinary goldmine</h2>



The world of fine dining celebrates truffles for their rarity and enticing <a href="https://www.earth.com/news/growing-environment-impacts-the-aroma-of-beer-and-hops/" target="_blank" rel="noreferrer noopener">aroma</a>. And the discovery of these new species may have just expanded the potential for gastronomic innovation. 



These species could hold tremendous economic potential due to their aromatic compounds.



Now, imagine a plate of gourmet truffle-infused pasta, accompanied by a glass of whiskey - a fine blend of the robust, earthy flavours of truffles and oaky whiskey. 



That's just what Maker’s Mark, a distiller from Kentucky, hopes to provide. 



They are exploring the cultivation of the native T. cumberlandense, and aim to introduce a uniquely infused whiskey to the market soon.



<h2 class="wp-block-heading" id="h-aromatic-appeal-of-truffle-species">Aromatic appeal of truffle species</h2>



The culinary appeal of truffles mainly lies in the unique aroma they produce. Each species emits a distinct fragrance, which contributes to its culinary potential and, therefore, its value.



MSU’s professor Randy Beaudry from the Department of Horticulture worked with Bonito and Sow to identify these aroma-producing compounds. 



Using gas chromatography, they discovered that T. canirevelatum was rich in compounds that give it a savory garlic aroma.



On the other hand, T. cumberlandense contained compounds found in the revered Périgord black truffle and the Piedmont white truffle.



<h2 class="wp-block-heading" id="h-significance-of-the-truffle-dogs">Significance of the "truffle dogs"</h2>



This significant discovery highlights the importance of trained truffle dogs in <a href="https://www.earth.com/news/crops-of-the-future-potatoes-that-thrive-in-heatwaves/" target="_blank" rel="noreferrer noopener">tuber</a> research and farming. 



"We suspect many native tuber species remain to be discovered and described. This task will be enhanced through the continued collaboration between mycologists (scientists who study fungi), the public and trained truffle dogs,” concluded Bonito.



As the quest for novel species continues, it is clear that the world of truffles holds more delectable secrets yet to be unearthed.



<h2 class="wp-block-heading" id="h-truffle-cultivation-and-species-conservation">Truffle cultivation and species conservation</h2>



As truffle discoveries continue to emerge, the focus is shifting toward sustainable cultivation and conservation efforts. 



Truffles, often associated with European fine dining, have long been harvested from wild forests, making them susceptible to environmental changes and overharvesting. 



The discovery of native species like Tuber cumberlandense opens up new possibilities for domestic cultivation, thus reducing reliance on imported varieties and supporting local economies.



These newfound species also offer exciting opportunities for cultivation under controlled conditions, potentially ensuring their long-term availability and contributing to ecosystem health.



This includes studying optimal soil compositions, climate conditions, and symbiotic relationships with host trees. 



Cultivating these <a href="https://www.earth.com/news/scientists-all-fungi-matter-not-just-mushrooms/" target="_blank" rel="noreferrer noopener">fungi</a> not only presents an economic opportunity but also has ecological benefits, as they contribute to soil health and biodiversity.



<h2 class="wp-block-heading" id="h-sustainable-truffle-discovery">Sustainable truffle discovery</h2>



Furthermore, the role of citizen scientists and trained truffle dogs continues to be vital in locating and documenting species in diverse environments. 



As research efforts expand, collaborations between mycologists, farmers, and culinary experts could pave the way for a sustainable truffle industry where these culinary treasures are both abundant and are grown in an environmentally responsible manner.



The discovery of the new species is detailed in the journal <a href="https://www.tandfonline.com/doi/full/10.1080/00275514.2024.2407755#:~:text=Tuber%20canaliculatum%20is%20sometimes%20wild,Berch%202020%3B%20Fortier%20et%20al.&amp;text=2022).,-Members%20of%20the">Mycologia</a>.

Two new truffle species discovered with the help of special 'truffle dogs'

Truffles have long captivated the senses, with their tantalizing aroma...

In a world where food security remains a pressing challenge, scientists continue to seek innovative ways to enhance crop production. A recent study from the University of Tasmania has uncovered a crucial role for auxin, a tiny but powerful plant hormone, in determining how plants store energy. 



The findings, published in the journal Nature Communications, reveal that auxin is not just a growth regulator - it plays a pivotal role in starch production.



This discovery has profound implications for global agriculture, offering new possibilities for increasing the starch content of staple crops such as rice, maize, and peas. If harnessed effectively, auxin could help improve food availability for billions of people worldwide.



<h2 class="wp-block-heading" id="h-auxin-not-just-a-growth-hormone">Auxin: Not just a growth hormone</h2>



For decades, auxin has been recognized as a master regulator of <a href="https://www.earth.com/news/plant-seeds-go-dormant-to-avoid-harsh-conditions/" target="_blank" rel="noreferrer noopener">plant development</a>. It influences various growth processes, from cell elongation to root formation. 



However, the new research from the <a href="https://www.utas.edu.au" target="_blank" rel="noreferrer noopener">University of Tasmania</a> has shown that auxin also plays a critical role in energy storage, particularly in the form of starch accumulation within seeds.



"It turns out this tiny molecule holds the key to how plants store energy, particularly in the form of starch," said study co-author Professor John Ross.



This discovery challenges the long-held view that auxin is primarily involved in plant growth. Instead, the findings indicate that auxin acts as a central orchestrator of starch formation in crops. Without auxin, seeds cannot efficiently stockpile starch, a component that makes up 60-80% of rice grains.



Given that rice is a staple <a href="https://www.earth.com/news/world-food-day-fighting-global-hunger/" target="_blank" rel="noreferrer noopener">food</a> for more than half of the world’s population, understanding how auxin regulates starch production could have major consequences for food security.



<h2 class="wp-block-heading" id="h-mechanisms-behind-starch-accumulation">Mechanisms behind starch accumulation</h2>



The study integrates a wide range of research, including the team’s own experiments, to establish how auxin drives starch accumulation in seeds. The researchers found that auxin operates through three interconnected mechanisms. 



First, it stimulates the activity of starch-producing genes, ensuring that plants can efficiently synthesize starch at the genetic level. 



Second, auxin plays a crucial role in energy generation within seeds, providing the necessary fuel for starch biosynthesis. 



Finally, the hormone ensures that sugar is transported efficiently into developing seeds, ensuring a steady supply of raw materials for starch formation.



These findings present a more comprehensive picture of how auxin functions beyond its well-documented role in plant growth. 



The research team developed a hypothetical model that integrates these three mechanisms, providing a framework for future studies into how auxin promotes starch accumulation across different plant systems.



<h2 class="wp-block-heading" id="h-transforming-food-security-with-auxin">Transforming food security with auxin</h2>



As the global population continues to rise, the demand for staple crops such as rice and maize is expected to increase significantly. 



The findings of this study open up exciting possibilities for enhancing crop yields naturally. By fine-tuning auxin pathways, scientists could potentially supercharge starch production in key crops, making them more productive and resilient to environmental stresses.



Professor Ross described the discovery as a major breakthrough with the potential to address some of the biggest challenges in agriculture today. "Understanding auxin's role could be a game-changer, especially for crops that billions rely on," he said.



Rather than introducing genetically modified traits or synthetic chemicals, researchers could leverage auxin, a hormone that plants already produce, to enhance carbohydrate accumulation in crops. 



This approach offers a sustainable and environmentally friendly way to increase food production without compromising plant health.



Dr. Erin McAdam, another co-author of the study, emphasized the enormous potential of this research in tackling <a href="https://www.earth.com/news/global-diet-shifts-the-hidden-costs-of-what-we-eat/" target="_blank" rel="noreferrer noopener">food</a> security challenges.



"Our work shows how a hormone plants already make can be harnessed to naturally boost carbohydrates in seed crops. There is huge scope for fundamental and applied research in this area, work that is critical if we want to feed billions of people," she said.



<h2 class="wp-block-heading" id="h-a-new-frontier-in-crop-science">A new frontier in crop science</h2>



While these findings offer exciting possibilities, scientists caution that further research is needed to fully understand auxin’s role in starch synthesis. 



The study lays a strong foundation for future exploration, but unlocking the full potential of auxin-based crop enhancement will require additional studies across different plant species and growing conditions.



The implications of this research extend beyond rice and maize. Other staple crops, including wheat, barley, and legumes, could also benefit from a better understanding of auxin’s impact on starch production. 



If researchers can develop targeted methods to enhance auxin’s activity in seeds, it may be possible to create crops that not only yield more but also provide greater nutritional value.



<h2 class="wp-block-heading" id="h-path-toward-global-food-security">Path toward global food security</h2>



The discovery that auxin plays a key role in starch accumulation marks an important step forward in agricultural science. 



With global food security under increasing pressure due to climate change, population growth, and limited arable land, innovative solutions are needed to ensure a stable <a href="https://www.earth.com/news/we-are-in-a-race-against-time-to-save-our-food-supply-from-climate-change/" target="_blank" rel="noreferrer noopener">food supply</a>. 



Auxin-based approaches offer a promising, natural way to enhance crop productivity without relying on genetic modification or chemical interventions.



By continuing to investigate auxin’s functions, scientists may unlock new strategies to optimize plant growth and energy storage, paving the way for more resilient and abundant food crops. 



The road ahead is filled with possibilities, and while more research is needed, the potential benefits of harnessing auxin are too significant to ignore. If successful, this tiny molecule could play a massive role in shaping the future of food security worldwide.



The study is published in the journal <a href="https://www.nature.com/articles/s41467-024-55756-z" target="_blank" rel="noreferrer noopener">Nature Communications</a>.&nbsp;

Tiny molecule could shape the future of food security

In a world where food security remains a pressing challenge,...

Many individuals aspire not just to live as long as possible, but to remain healthy and active throughout their lifespan. Yet as people get older, the likelihood of encountering conditions such as Alzheimer’s disease and sarcopenia (a gradual loss of muscle mass and strength) increases.&nbsp;



In a new effort to promote healthy aging, researchers from the <a href="https://www.isas.de/" target="_blank" rel="noreferrer noopener">Leibniz Institute for Analytical Sciences</a> (ISAS) have discovered that the natural compound ergothioneine can boost the health span of aging animals.&nbsp;



The findings, published in the journal <a href="https://dx.doi.org/10.1016/j.cmet.2024.12.008" target="_blank" rel="noreferrer noopener">Cell Metabolism</a>, provide insights into this substance’s potential for safeguarding against age-related diseases.



<h2 class="wp-block-heading" id="h-anti-aging-benefits-of-a-mushroom-compound">Anti-aging benefits of a mushroom compound </h2>



Ergothioneine occurs naturally in certain <a href="https://www.earth.com/news/secrets-of-fungi-diversity-can-be-pulled-out-of-thin-air/" target="_blank" rel="noreferrer noopener">fungi</a>. The compound can be found in oyster and shiitake mushrooms, as well as in fermented foods. It is often marketed as a dietary supplement or added to cosmetics to provide “anti-aging” benefits, yet the underlying mechanism behind these benefits has been poorly understood.



“Our analyses now finally provide clarity about the mechanism and also show that ergothioneine has promising therapeutic potential for the prevention of age-related diseases,” said Miloš Filipović, corresponding author and head of the ERC Sulfaging research group at ISAS.



<h2 class="wp-block-heading" id="h-enhancing-lifespan-mobility-and-resistance-to-stress">Enhancing lifespan, mobility, and resistance to stress</h2>



In their study, the researchers explored how ergothioneine affects various animals, including the model organism Caenorhabditis elegans (a nematode).&nbsp;



Scientists at ISAS noted that giving ergothioneine from young adulthood not only lengthened the worms’ lives, but also increased their mobility, boosted their capacity to handle stress, and lowered markers linked with <a href="https://www.earth.com/news/drinking-tea-every-day-proven-studies-to-delay-biological-aging-in-humans/" target="_blank" rel="noreferrer noopener">aging</a>.



“As the animals got older, the contrast with the control group became more significant. In addition, we did not observe any undesirable side effects - nor did other studies,” said Dunja Petrovic, whose doctoral research at ISAS contributed to the publication.



Collaborators at the <a href="http://arhiva.rect.bg.ac.rs/en/index.php" target="_blank" rel="noreferrer noopener">University of Belgrade</a> observed similar effects in mammals, testing ergothioneine on six nine-month-old rats for three weeks. They administered roughly 10 milligrams of ergothioneine per day, equivalent to the amount found in 4.5 grams of dried oyster mushrooms.&nbsp;



Not only did the rats show better endurance, but they also experienced increased muscle mass, greater vascularization of muscle tissue, and higher numbers of muscle stem cells, indicating potential relevance for preventing <a href="https://www.earth.com/news/molecule-in-coffee-trigonelline-keeps-muscles-young/" target="_blank" rel="noreferrer noopener">sarcopenia</a>.



<h2 class="wp-block-heading" id="h-strengthening-cells-through-hydrogen-sulfide">Strengthening cells through hydrogen sulfide</h2>



To understand the processes behind these observations, the research team used mass spectrometry on human and mouse cell cultures. They found that ergothioneine can serve as an alternative substrate for cystathionine-γ-lyase (CSE), a key enzyme involved in producing hydrogen sulfide (H₂S).&nbsp;



This signaling molecule helps shield cells from oxidative stress via persulfidation - a cellular process previously shown to decline with age, but which can be positively influenced by dietary factors.



Prior work from 2019 by Filipović and colleagues has demonstrated that the rate of persulfidation decreases over time, potentially contributing to age-related problems ranging from <a href="https://www.earth.com/news/a-century-of-progress-in-the-fight-against-cardiovascular-disease/" target="_blank" rel="noreferrer noopener">cardiovascular disease</a> to neurodegenerative disorders.&nbsp;



The new data expands upon those findings, demonstrating how ergothioneine specifically stimulates persulfidation of glycerol-3-phosphate dehydrogenase (GPDH). This upregulation of GPDH, in turn, promotes higher levels of NAD+, a coenzyme known for supporting increased lifespan.



“The human body is not able to produce ergothioneine itself. However, such a specific utilization mechanism suggests that it is very important for us,” Petrovic said.&nbsp;



Scientists at <a href="https://www.uni-heidelberg.de/en" target="_blank" rel="noreferrer noopener">Heidelberg University</a>, the <a href="https://www.cam.ac.uk/" target="_blank" rel="noreferrer noopener">University of Cambridge</a>, and ISAS verified that ergothioneine’s benefits rely on the CSE-dependent pathway.



<h2 class="wp-block-heading" id="h-maintaining-better-health-with-age">Maintaining better health with age</h2>



Encouraged by these promising outcomes, the researchers examined the effects of a brief, five-day treatment of ergothioneine in young rats. A daily dose of about 10 milligrams significantly raised their endurance and boosted NAD+ levels in their blood serum.



“This indicates that ergothioneine influences the metabolism in a similar way to performance-enhancing agents,” Filipović said. He plans to carry out a study involving healthy human volunteers to evaluate whether the compound can similarly enhance performance in people.



By offering a clearer perspective on how ergothioneine improves muscle health, stress resilience, and cellular defenses, this research sets the stage for new strategies aimed at maintaining good health into advanced age.&nbsp;



As further investigations confirm these findings in humans, the mushroom compound ergothioneine may emerge as a valuable resource for countering age-related diseases and promoting a more robust, active life.

Mushroom compound  linked to better health and longer life

Many individuals aspire not just to live as long as...

Berries from the genus Aronia, often called black chokeberry, are native to North America and have gained attention for their high content of polyphenolic compounds. 



These natural chemicals have been associated with benefits that go beyond ordinary nutrition, such as antioxidant effects that may help calm the body’s inflammatory processes. 



People have started asking about aronia’s place in <a href="https://www.earth.com/news/meal-timing-has-a-major-influence-on-our-health/">everyday meals</a>, hoping to see if a simple fruit could support healthy lifestyles.



<h2 class="wp-block-heading" id="h-a-rising-focus-on-aronia">A rising focus on aronia</h2>



Scientists recently examined whether aronia juice might protect against diet-induced challenges linked to the gut microbiome.



This project was led by <a href="https://www.montana.edu/news/22109/stephanie-wilson-one-of-first-three-students-to-complete-montana-state-s-individual-interdisciplinary-ph-d-program">Dr. Stephanie M. G. Wilson</a> from Montana State University. Research in this area has looked at how bacteria in the digestive system respond when aronia berries are introduced, particularly in situations where unhealthy eating patterns could raise inflammation.&nbsp;



Early investigations point to intriguing changes in microbes, and hinting that this berry might shift certain bacterial communities and reduce the strain triggered by high-fat diets.



<h2 class="wp-block-heading" id="h-science-behind-the-findings">Science behind the findings</h2>



The research team used a mouse model with transplanted human gut microbiomes that came from donors with different inflammation levels.&nbsp;



“Aronia supplementation provided robust protection,” noted Dr. Wilson when reviewing the results at the end of the study. Scientists saw increases in <a href="https://www.earth.com/news/gut-bacteria-have-very-clever-ways-of-supporting-human-health/">Eggerthellaceae</a>, a family of bacteria that can process polyphenols.&nbsp;



Some data also linked <a href="https://extension.umn.edu/trees-and-shrubs/black-chokeberry" target="_blank" rel="noreferrer noopener">black chokeberry</a> intake with changes in metabolites related to improved gut barriers. 



These shifts suggest that eating or drinking aronia-based products might assist in keeping the digestive system more balanced during periods of dietary stress.



<h2 class="wp-block-heading" id="h-personalizing-nutrition">Personalizing nutrition</h2>



Inflammation can arise when people eat high-fat or sugary foods for long stretches. Researchers point out that a person’s unique microbiome might determine how well they adapt to certain dietary habits. 



Aronia’s <a href="https://www.mdpi.com/1420-3049/27/22/7823">benefits</a> may vary from one person to another, depending on individual gut ecology and background health status. 



For those who carry a set of gut bacteria already geared toward lower inflammation, the advantages from adding aronia might be more visible. 



This concept underscores how science is moving toward personalized nutrition, where different bodies respond to the same foods in slightly different ways.



<h2 class="wp-block-heading" id="h-exploring-new-directions">Exploring new directions</h2>



Other published works indicate that aronia is not just a source of antioxidants; it may also be linked with healthier glucose levels and heart function.&nbsp;



The presence of anthocyanins and other phenolic substances could explain how this fruit influences complex pathways connected to metabolism. 



Traditional uses of aronia include juices, jams, and powders, but emerging science is urging a closer look at its larger dietary potential. 



While some folks already consume aronia to freshen up their breakfast or snack routines, others remain unaware of its possible contributions to gut stability.



<h2 class="wp-block-heading" id="h-unraveling-unexpected-twists">Unraveling unexpected twists</h2>



Some findings highlight the importance of gut diversity when it comes to inflammation. Researchers observed that mice with microbiomes from donors who had lower inflammation were more resilient during the <a href="https://www.earth.com/news/high-fat-diets-cause-high-anxiety-through-changes-in-gut-bacteria/">high-fat diet</a> challenge.&nbsp;



Aronia seemed to shield this group even further. This suggests that, while aronia might help most individuals, those who have specific microbial imbalances might notice the biggest improvements.&nbsp;



On a broader level, it points to how small dietary changes, like adding a berry drink, can create ripple effects that protect overall wellness.



<h2 class="wp-block-heading" id="h-applications-on-the-horizon">Applications on the horizon</h2>



Aronia’s tart flavor might not suit everyone right away. In grocery stores, it often appears in juice blends, concentrates, or dried forms. 



Because it’s easy to mix with other fruits, people can add it to smoothies or desserts without changing their routines too drastically. 



Research continues to evaluate how much aronia consumption is ideal for humans, since the dose can vary widely. 



In some clinical trials, individuals experienced potential <a href="https://www.earth.com/news/tackling-fat-with-food-tropical-plant-in-china-has-anti-obesity-properties/">anti-obesity benefits</a>, in addition to improvements in the body’s natural defenses. These early observations pave the way for deeper investigations.



<h2 class="wp-block-heading" id="h-final-thoughts">Final thoughts</h2>



Aronia may carry special ingredients that bolster the gut’s ability to cope with stress, especially during nutritional challenges. Investigators are looking to see if these insights might lead to new strategies for lowering inflammation in the long term.



This berry isn’t a magic bullet, and results will differ from person to person. Its potential, though, goes beyond just delivering antioxidants: it may connect with gut microbes in ways that support healthy balance. Fresh interest in aronia keeps growing, and the findings so far hint at a fruitful path for future study. The study is published in <a href="https://www.frontiersin.org/journals/nutrition/articles/10.3389/fnut.2023.1244692">Frontiers</a>.

The debate about when our ancestors started eating meat has taken an unexpected turn. While we've long associated early human evolution with meat consumption, a recent study reveals that some of our earliest ancestors stuck to a mostly plant-based diet.



The research was led by Dr. Tina Lüdecke from the Max Planck Institute for Chemistry in Germany in collaboration with researchers from South Africa.



The findings challenge our previous assumptions about early hominin diets.



<h2 class="wp-block-heading" id="h-teeth-hold-clues-of-ancient-diets">Teeth hold clues of ancient diets</h2>



A team of researchers from the <a href="https://www.mpic.de" target="_blank" rel="noreferrer noopener">Max Planck Institute for Chemistry</a> in Germany and the University of the Witwatersrand (<a href="https://www.wits.ac.za" target="_blank" rel="noreferrer noopener">Wits University</a>) in South Africa analyzed nitrogen isotopes in the fossilized tooth enamel of seven Australopithecus individuals.



These fossils were recovered from the Sterkfontein Caves near Johannesburg, a site rich in <a href="https://www.earth.com/news/two-species-of-human-ancestors-literally-crossed-paths-1-5-million-years-ago/" target="_blank" rel="noreferrer noopener">early hominin</a> remains. 



By comparing these isotopic signatures to those of coexisting animals - including herbivores like antelopes and monkeys, as well as carnivores such as hyenas and big cats - the scientists established the positrons of Australopithecus in the prehistoric food web.



The nitrogen isotope ratios in the&nbsp;Australopithecus&nbsp;teeth were consistently low, closely resembling those of plant-eating animals. This strongly suggests that these early human ancestors primarily consumed a plant-based diet and did not regularly eat meat. 



While the researchers acknowledge that&nbsp;Australopithecus&nbsp;may have occasionally consumed animal proteins such as eggs or insects, their findings indicate that meat was not a significant part of their diet.



<h2 class="wp-block-heading" id="h-plant-based-vs-meat-diets">Plant-based vs. meat diets</h2>



The key to this discovery lies in the analysis of nitrogen isotopes, which provide reliable indicators of an animal’s diet. When animals digest food, their bodies process nitrogen in a way that leaves distinct chemical traces. 



Specifically, the ratio of heavy nitrogen isotopes (15N) to light nitrogen isotopes (14N) increases as one moves up the food chain. 



Herbivores, which consume plants, have lower nitrogen isotope ratios, while carnivores have higher ratios because they consume herbivores.



"Tooth enamel is the hardest tissue of the mammalian body and can preserve the isotopic fingerprint of an animal's diet for millions of years," noted geochemist Tina Lüdecke.



<h2 class="wp-block-heading" id="h-nitrogen-isotopes-reveal-ancient-diets">Nitrogen isotopes reveal ancient diets</h2>



By measuring nitrogen isotope ratios in fossilized tooth enamel, scientists can determine whether an <a href="https://www.earth.com/news/fossil-discovery-anadoluvius-turkae-suggests-humans-originated-in-europe-not-africa/" target="_blank" rel="noreferrer noopener">organism</a> primarily consumed plants or animals. 



While this method has been widely used to study the diets of modern animals and humans, it was previously limited to fossils only tens of thousands of years old due to the degradation of organic material over time. 



However, Lüdecke and her team applied a breakthrough technique developed in Alfredo Martínez-García’s laboratory at the Max Planck Institute for Chemistry. This method allowed the researchers to extract nitrogen isotope data from fossilized tooth enamel that is millions of years old.



<h2 class="wp-block-heading" id="h-evolution-of-meat-in-diets">Evolution of meat in diets</h2>



One of the most significant aspects of this study is how it challenges existing <a href="https://www.earth.com/news/first-tools-ever-made-on-earth-hominins-3-million-years-ago-cradle-of-humankind/" target="_blank" rel="noreferrer noopener">theories</a> about the role of meat in human evolution. 



Many researchers have theorized that the consumption of animal resources, especially meat, played a crucial role in the development of larger brains and more advanced tool-making abilities.



The protein and fat found in meat have been linked to the evolutionary increase in brain size seen in later hominins. However, direct evidence of when meat became a staple in the human diet has remained elusive.



<h2 class="wp-block-heading" id="h-australopithecus-did-not-eat-meat">Australopithecus did not eat meat</h2>



The findings from this study suggest that&nbsp;Australopithecus&nbsp;did not regularly hunt or consume large mammals, unlike Neanderthals, who lived millions of years later and actively pursued large game. 



This implies that the shift toward a meat-based diet occurred later in human evolution, possibly with the emergence of the genus&nbsp;Homo.



"This method opens up exciting possibilities for understanding <a href="https://www.earth.com/news/amazing-adaptation-early-humans-thrived-in-extreme-conditions/" target="_blank" rel="noreferrer noopener">human evolution</a>," said Martínez-García. "It has the potential to answer crucial questions, for example, when did our ancestors begin to incorporate meat in their diet? And was the onset of meat consumption linked to an increase in brain volume?"



<h2 class="wp-block-heading" id="h-major-breakthrough-in-dietary-research">Major breakthrough in dietary research</h2>



This research represents a major breakthrough in the study of ancient diets. Previous studies relied on indirect evidence, such as tool use and wear patterns on teeth, to infer what early hominins ate. 



However, by directly measuring nitrogen isotopes in fossilized tooth enamel, Lüdecke’s team has provided the most concrete evidence yet that&nbsp;Australopithecuswas largely herbivorous.



"This work represents a huge step in extending our ability to better understand diets and trophic levels of all animals back into the scale of millions of years. The research provides clear evidence that its diet did not contain significant amounts of meat," said Professor Dominic Stratford, director of research at the Sterkfontein Caves.



"We are honored that the pioneering application of this new method was spearheaded at Sterkfontein, a site that continues to make fundamental contributions to science even 89 years after the first hominin fossils were discovered there by Robert Broom."



<h2 class="wp-block-heading" id="h-future-research-directions">Future research directions</h2>



Lüdecke’s team now plans to expand their research by analyzing fossilized tooth enamel from other early hominin species across different time periods and geographic regions. 



By collecting data from key fossil sites in eastern and southern Africa as well as Southeast Asia, they hope to better understand when and how meat consumption became a regular part of the human diet.



The research could help answer long-standing questions about whether the introduction of meat provided an evolutionary advantage.



Did meat consumption contribute to the development of larger brains? Did it play a role in social structures and hunting behaviors? These are the types of questions that future studies will seek to address.



The study, funded by the Max Planck Society and supported by the German Research Foundation’s Emmy Noether program, marks a major advancement in the field of paleoanthropology.



By applying cutting-edge scientific techniques to ancient fossils, researchers are now able to uncover new details about the dietary habits of our <a href="https://www.earth.com/news/stone-tool-flint-discovery-challenges-theory-of-human-cultural-evolution/" target="_blank" rel="noreferrer noopener">distant ancestors</a>.



<h2 class="wp-block-heading" id="h-meat-and-diet-of-human-ancestors">Meat and diet of human ancestors </h2>



The findings from this study challenge traditional assumptions about early human diets. Rather than being early hunters,&nbsp;Australopithecus&nbsp;appears to have relied primarily on plant-based food. 



This research provides a clearer picture of how human nutrition evolved over millions of years and highlights the importance of continued exploration in the field of evolutionary anthropology.



As scientists refine their methods and expand their dataset, we may soon uncover even more details about the dietary habits that shaped the course of human evolution. 



One thing is clear - our journey from plant eaters to omnivorous beings was not as straightforward as once thought.



The study is published in the journal <a href="https://www.science.org/doi/10.1126/science.adq7315" target="_blank" rel="noreferrer noopener">Science</a>.

Early humans had surprising diets 3.5 million years ago

The debate about when our ancestors started eating meat has...

Our world is warming, and ecosystems are shifting in response. Some changes are obvious - like flowers blooming earlier - but many are subtle and complex. One of the most important factors in this transformation is phenology, the timing of natural events, such as seed germination and plant growth.



A new study from Holden Forests &amp; Gardens sheds light on how warming influences plant communities by altering germination timing.



<h2 class="wp-block-heading" id="h-role-of-germination-timing-in-plants">Role of germination timing in plants</h2>



Germination timing plays a crucial role in shaping entire ecosystems, not just individual plant species. When a seed starts growing, its timing determines how well it competes for resources like sunlight, water, and nutrients. 



Some plants adjust quickly to <a href="https://www.earth.com/news/predicting-how-climate-change-will-alter-plant-growth-cycles/" target="_blank" rel="noreferrer noopener">warmer temperatures</a>, germinating earlier in the season, while others stick to their usual schedule. This shift in timing can disrupt the ecological balance, allowing certain species to dominate and altering the overall plant community.



If a species germinates earlier, it may grow larger and take up more space, outcompeting others that germinate later. Over time, this change can influence which species thrive and which decline - ultimately affecting animals, insects, and other organisms that depend on those plants.



<h2 class="wp-block-heading" id="h-germination-in-different-plant-species">Germination in different plant species</h2>



To better understand how climate change affects plant communities, a research team led by Emma Dawson-Glass from the <a href="https://holdenfg.org/katie-stuble-lab/" target="_blank" rel="noreferrer noopener">Stuble Lab</a> conducted a controlled study. They focused on 15 plant species commonly found in old-field ecosystems. 



The researchers designed an experiment that simulated two temperature conditions: one reflecting current climate conditions and another 3°C warmer to mimic future <a href="https://www.earth.com/news/climate-extremes-in-2024-what-have-we-learned/" target="_blank" rel="noreferrer noopener">warming</a> scenarios.



This setup allowed them to observe how temperature changes influenced the timing of seed germination.



The main objective of the study was to determine&nbsp;which plant species germinate earlier under warming&nbsp;and how that shift affects plant interactions. 



When certain species sprout earlier, they may gain a competitive advantage, growing larger and outcompeting other plants for sunlight, nutrients, and water. This process can&nbsp;alter plant community compositionand disrupt ecological balance.



The findings provide strong evidence that&nbsp;climate change is already influencing ecosystems. Studying these patterns is crucial for predicting future shifts and developing strategies to manage and restore plant communities as the climate continues to warm.



<h2 class="wp-block-heading" id="h-winners-and-losers-in-a-warmer-world">Winners and losers in a warmer world</h2>



The study found that plants with greater phenological flexibility had a competitive edge. 



Plant species like&nbsp;curly dock (Rumex crispus), wrinkleleaf goldenrod (Solidago rugosa),&nbsp;and&nbsp;tall ironweed (Vernonia gigantea)&nbsp;grew significantly larger when they germinated earlier in a warmed <a href="https://www.earth.com/news/plants-defy-climate-change-through-acclimation/" target="_blank" rel="noreferrer noopener">environment</a>. 



Meanwhile, species such as&nbsp;spotted St. John’s wort (Hypericum punctatum), bristly buttercup (Ranunculus pensylvanicus),&nbsp;and&nbsp;Canada goldenrod (Solidago canadensis)&nbsp;performed better in current conditions, struggling when warming altered the timing of their establishment.



However, not all plants showed a clear response - some maintained stable growth regardless of warming. This variability suggests that climate change will not affect all species equally, creating an unpredictable future for plant communities.



<h2 class="wp-block-heading" id="h-implications-for-ecosystem-management">Implications for ecosystem management</h2>



"This work illustrates that warming can change the order of species arrivals, ultimately reshaping community composition,” said Dawson-Glass. These findings are crucial for conservationists and ecologists working to restore and manage plant communities in a rapidly changing world.



The study also highlights&nbsp;phenological sensitivity, the ability of species to adjust their timing in response to seasonal changes. 



“Our results provide a new perspective on how climate change is already shaping ecosystems in ways we’re only beginning to understand,” said Katharine Stuble.



<h2 class="wp-block-heading" id="h-future-of-plant-germination">Future of plant germination </h2>



As climate change accelerates, shifts in germination timing are altering ecosystems by affecting&nbsp;food webs, species competition, and biodiversity. Some plants germinate earlier due to warming, gaining a competitive edge over others. 



This can lead to&nbsp;changes in plant community structure, where dominant <a href="https://www.earth.com/news/world-soil-day-2024-protecting-our-planets-lifeline/" target="_blank" rel="noreferrer noopener">species</a> thrive while others struggle. Over time, these shifts impact herbivores that rely on specific plants for food, which in turn affects predators and the broader ecosystem.



The research at&nbsp;<a href="https://holdenfg.org/" target="_blank" rel="noreferrer noopener">Holden Forests &amp; Gardens</a>&nbsp;contributes to a growing understanding of how these changes unfold. 



By studying phenology - the timing of natural events - scientists can predict and manage the effects of climate change on plant communities. This knowledge is crucial for conservation efforts, helping land managers restore and maintain biodiversity.



As ecosystems continue to shift, understanding phenology will be essential in developing strategies to&nbsp;adapt to a warming world and protect ecological balance.



The study is published in the journal <a href="https://esajournals.onlinelibrary.wiley.com/doi/10.1002/ecy.4504" target="_blank" rel="noreferrer noopener">Ecology</a>.

Climate warming alters plant germination and disrupts ecosystem balance

Our world is warming, and ecosystems are shifting in response....

Continental European snakes, geckos, and Italian wall lizards are silently making their way to northern Europe. They travel undetected among ornamental plants such as olive trees that are imported for gardens and green spaces.



These hidden plant hitchhikers can become invasive species, threatening native ecosystems - just as they have in snake-free Mediterranean islands like Majorca.



<h2 class="wp-block-heading" id="h-importing-ornamental-plants">Importing ornamental plants </h2>



The presence of these reptiles signals a larger problem. Ornamental plants and cut flowers transport a wide range of pests, including insects, fungi, and disease-carrying organisms. These shipments move at high speed and in large volumes, making thorough inspections nearly impossible.



A study published in the journal Bioscience warns that despite regulations, imported plants pose an <a href="https://www.earth.com/news/growing-threat-of-invasive-species-requires-immediate-action/" target="_blank" rel="noreferrer noopener">increasing risk</a>. The global market for ornamental plants is expanding rapidly, and stronger regulations are urgently needed to prevent environmental and agricultural damage.



“Ornamental olive trees for sale in the UK can be over 100 years old, with many hiding places amongst their gnarly bark and the soil they’re transported in. This is incredibly risky in terms of importing pests,” said Professor William Sutherland from the <a href="https://www.cam.ac.uk/" target="_blank" rel="noreferrer noopener">University of Cambridge</a>.



“Adult snakes and lizards are just the tip of the iceberg. If they’re getting through, what’s the chance of us spotting small insects and fungi - the things that really cause the problems?”



“The sheer volume of cut flowers and ornamental plants being traded at speed around the world makes it extremely difficult to intercept all the pests and diseases they carry. Even with the best of intentions, unwanted hitchhikers are getting through customs import checks all the time,” added Dr. Silviu Petrovan, a researcher from Cambridge.



<h2 class="wp-block-heading" id="h-illegal-plant-trade-and-wild-pests">Illegal plant trade and wild pests </h2>



The problem goes beyond pests. Some suppliers ignore regulations, illegally stripping orchids and cacti from tropical <a href="https://www.earth.com/news/invasive-plants-alter-the-soundscape-of-ecosystems/" target="_blank" rel="noreferrer noopener">habitats</a> and selling them as part of legal shipments. Enforcing trade protections on a large scale is challenging, making it easier for endangered species to be exploited.



“Even with a global trade in cultivated ornamental plants, there is still a market for rare <a href="https://www.earth.com/news/time-bombs-invasive-plants-can-lie-dormant-for-centuries/" target="_blank" rel="noreferrer noopener">species</a> taken from the wild, and this can lead to rapid species declines, as well as increased risks that wild pests and plant diseases may enter the supply chain,” warned Dr. Amy Hinsley from the <a href="https://www.ox.ac.uk/" target="_blank" rel="noreferrer noopener">University of Oxford</a>.



<h2 class="wp-block-heading" id="h-a-frog-s-journey-to-sheffield">A frog’s journey to Sheffield</h2>



For Dr. Petrovan, the issue became personal when he was called to identify a live frog found in a florist’s shop in Sheffield. Initially, he assumed it was a joke.&nbsp;



When Dr. Petrovan realized the tree frog had arrived from Colombia via Ecuador, he was shocked.



“Finding a South American tree frog in a Sheffield florist was extraordinary. It made me realize that if you can get this type of fragile small vertebrate arriving alive in a flower shipment without being noticed at customs, just how hard it must be to detect very small agricultural insect pests or their eggs,” said Dr. Petrovan.



To assess the scale of the problem, researchers analyzed records from Dutch customs (2017-2018) and the UK’s DEFRA (2021-2023). Over 80% of intercepted pests were insects, highlighting the difficulty of detection.



<h2 class="wp-block-heading" id="h-environmental-and-health-costs">Environmental and health costs</h2>



The study on invasive species reveals several serious concerns about the ornamental <a href="https://www.earth.com/news/non-native-species-are-spreading-at-an-exponential-rate/" target="_blank" rel="noreferrer noopener">plant</a> trade, particularly in the countries that supply these plants.&nbsp;



One major issue is pollution, as microplastics and agrochemicals used in plant cultivation contaminate soil and water systems. Another concern is the health risks faced by workers handling cut flowers which expose them to harmful pesticide residues. 



The industry’s high water consumption also threatens food security, especially in places like Kenya, where floriculture takes up to 98% of the water drawn from Lake Naivasha, reducing the availability of water for essential agriculture.&nbsp;



Additionally, transporting flowers across the world generates significant carbon emissions, with each flower producing up to 3kg of CO2 due to refrigeration and shipping. Beyond these <a href="https://www.earth.com/news/invasive-lionfish-global-domination-mediterranean-sea-marine-ecosystems/" target="_blank" rel="noreferrer noopener">environmental impacts</a>, the exploitation of wild plants remains a critical problem.&nbsp;



Many endangered species, such as rare cacti, succulents, and orchids, continue to be taken from their natural habitats to meet demand, putting these species at further risk of extinction.



<h2 class="wp-block-heading" id="h-need-for-sustainable-solutions">Need for sustainable solutions</h2>



Despite its risks, the ornamental plant industry supports many rural economies. In 2022, the global export value of cut flowers and foliage reached $10 billion, while live plants and bulbs totaled $13 billion.



“We absolutely don’t want to encourage knee-jerk reactions that might be well-meaning but actually cause more problems than they solve,” said Dr. Petrovan. Instead, he advocates for better industry standards. 



“We need to push to make the industry more sustainable through things like certifications and better regulation, and to work with those involved in the trade to better understand the <a href="https://www.earth.com/news/new-invasive-crustacean-species-discovered-in-the-mediterranean/" target="_blank" rel="noreferrer noopener">risks</a> and how to mitigate them,” added Dr. Petrovan.



<h2 class="wp-block-heading" id="h-the-role-of-responsible-consumers">The role of responsible consumers</h2>



“We need to be responsible consumers. While certification standards are being developed, buying plants rather than cut flowers can reduce many of the risks that stem from importing cut flowers. They last much longer and also reduce the emission costs,” said Dr. Alice Hughes from the University of Hong Kong (<a href="https://www.hku.hk/" target="_blank" rel="noreferrer noopener">HKU</a>).



The ornamental plant trade is booming, but it carries hidden risks. From invasive reptiles to agricultural pests, unchecked imports threaten ecosystems and food security.&nbsp;



Smarter regulations, responsible sourcing, and consumer awareness can help create a more sustainable future - without sacrificing the beauty that plants and flowers bring to our lives.

International plant trade is spreading invasive species and pests

Continental European snakes, geckos, and Italian wall lizards are silently...

Imagine a world where robotic insects take over the critical task of pollination, freeing farmers from relying on the whims of nature or resorting to manually pollinating crops with paintbrushes. 



These high-tech marvels, inspired by nature’s own pollinators, promise to revolutionize agriculture by boosting efficiency and reducing environmental impact. 



Scientists at MIT are diligently working to reinvent artificial pollination, which will bring us closer to this sensational reality.



<h2 class="wp-block-heading" id="h-small-pioneers-of-giant-transformations">Small pioneers of giant transformations</h2>



These tiny mechanical marvels that are smaller than the size of a paperclip are expected to expedite <a href="https://www.earth.com/news/insect-apocalypse-australasia-is-facing-a-hidden-pollination-crisis/" target="_blank" rel="noreferrer noopener">pollination</a>, thereby boosting crop yields while minimizing traditional agriculture's harmful effects on the environment.



Inspired by bees, these robotic insects could soon swarm out of mechanical hives to perform precise pollination, mimicking the efficiency and agility of their natural counterparts.



<h2 class="wp-block-heading" id="h-the-inception-of-robotic-insects">The inception of robotic insects</h2>



<a href="https://www.mit.edu/" target="_blank" rel="noreferrer noopener">MIT</a> researchers drew inspiration from bees to design these <a href="https://www.earth.com/news/tiny-robotic-fish-developed-to-collect-microplastics/" target="_blank" rel="noreferrer noopener">miniature robots</a>. 



Kevin Chen, an associate professor in the Department of Electrical Engineering and Computer Science (EECS), head of the Soft and Micro Robotics Laboratory within the Research Laboratory of Electronics (RLE), and the senior author of an open-access paper on the new design, leads this innovative project.



Chen and his team recognized that earlier versions of robotic insects lacked the endurance, speed, and maneuverability of natural <a href="https://www.earth.com/news/pollinators-are-not-just-attracted-to-plants-by-scent-but-also-by-humidity/" target="_blank" rel="noreferrer noopener">pollinators</a>. 



This led them to redesign the robots, mimicking the anatomy and flight mechanics of bees to achieve greater efficiency and precision.



The research team, including co-lead authors Suhan Kim and Yi-Hsuan Hsiao, EECS graduate students, collaborated with Zhijian Ren and summer visiting student Jiashu Huang to produce their findings, which were published in Science Robotics.



<h2 class="wp-block-heading" id="h-the-evolution-of-robotic-insects">The evolution of robotic insects</h2>



The latest robotic insects represent a significant leap in design. 



The revamped bots can hover for about 1,000 seconds - over 100 times longer than their predecessors.



Weighing less than a paperclip, these robots achieve remarkable speeds, perform acrobatic stunts like double flips, and track trajectories as intricate as spelling "M-I-T."



The design improvements include more sophisticated transmissions that connect the wings to soft actuators, or artificial muscles, which minimize mechanical strain while increasing precision and agility. 



Each unit now features a single wing pointing outward, which reduces interference between wings and creates space for future enhancements, such as tiny batteries or sensors.



<h2 class="wp-block-heading" id="h-overcoming-challenges">Overcoming challenges </h2>



Initial designs, with four units and eight wings, faced issues where the wings interfered with each other’s lift forces. 



"But there is no <a href="https://www.earth.com/news/global-insect-decline-what-are-the-causes-and-consequences/" target="_blank" rel="noreferrer noopener">insect</a> that has eight wings. In our old design, the performance of each individual unit was always better than the assembled robot," Chen remarked.



The team halved the number of wings and reconfigured their alignment, significantly improving flight performance.



Fabricating the wing hinges was another challenge. 



These 2-centimeter-long, 200-micron-wide components required a multistep laser-cutting process to ensure precision. 



"If you have even a tiny alignment issue during the fabrication process, the wing hinge will be slanted instead of rectangular, which affects the wing kinematics," Chen explained.



<h2 class="wp-block-heading" id="h-the-promise-of-progress">The promise of progress </h2>



The latest design breakthroughs bring the team closer to practical applications like assisted pollination.



“The amount of flight we demonstrated in this paper is probably longer than the entire amount of <a href="https://www.earth.com/news/hummingbird-wings-the-future-of-robotic-flight/" target="_blank" rel="noreferrer noopener">flight</a> our field has been able to accumulate with these robotic insects,” Chen shared.



Future goals include achieving flight durations in excess of 10,000 seconds and enhancing the robots’ precision to land and take off from flower centers.



In the long term, the team envisions equipping the robots with sensors, batteries, and computing capabilities for autonomous navigation outside the lab.



<h2 class="wp-block-heading" id="h-a-glimpse-into-the-future">A glimpse into the future</h2>



As Kevin Chen and his team continue to push the boundaries of robotic insect design, the promise of swarming, battery-powered pollinators edges closer to reality. 



With each iteration, these miniature marvels become more efficient, agile, and precise, bringing them one step closer to deployment in real-world environments.



They could bring revolutionary change in modern agriculture by making it possible to produce fruits and vegetables within controlled environments such as multilevel warehouses with robotic insects to remove the shackles of seasonality, climatic variability, and the decline of natural pollinators on crop production.



It is envisioned that such a shift would bring a surge in crop yield while opening doors to a greener, more responsible means of farm operation through pesticide-free and non-water hogging systems.



A whole vision of an army of robot pollinators marching across farms symbolizes technology with the science of biomimicry redefining everything related to the food sector. 



These robots may, one day, help solve some of the world's most pressing problems in food security and environmental conservation.

Robotic insects are here and may be the future of farming and plant pollination

Imagine a world where robotic insects take over the critical...

Apples are often seen as a go-to choice for boosting overall health. They are affordable, easy to find, and praised for their nutritional content.&nbsp;



Yet many folks never realize how these crisp favorites might be doing more than just satisfying a sweet tooth. They contain special plant compounds that appear to lend a helping hand to a part of the body that usually goes unnoticed until problems arise: the liver.



<h2 class="wp-block-heading" id="h-a-closer-look-at-flavonoids">A closer look at flavonoids</h2>



A recent publication in The American Journal of Clinical Nutrition pointed to a promising link between certain <a href="https://www.earth.com/news/early-humans-thrived-on-plant-based-diets-not-meat-alone-780000-years-ago/" target="_blank" rel="noreferrer noopener">plant-based diets</a> and lower chances of developing liver trouble.



<a href="https://www.scopus.com/authid/detail.uri?authorId=58875399600" target="_blank" rel="noreferrer noopener">William Bell</a>, who co-authored the study at the <a href="https://www.uea.ac.uk/" target="_blank" rel="noreferrer noopener">University of East Anglia</a>, found that people who regularly ate foods packed with flavonoids saw benefits that went beyond typical cholesterol or blood pressure improvements.



<a href="https://www.heart.org/en/news/2022/03/22/flavonoids-are-a-flavorful-way-to-boost-heart-and-brain-health" target="_blank" rel="noreferrer noopener">Flavonoids</a> are plant components that help protect living cells from stress. These compounds can be found in all sorts of foods, but apples are one of the standouts.&nbsp;



Apples also carry fiber, vitamins, and other antioxidants, so it is no surprise that they keep showing up in discussions about wellness. That extra dose of fiber, especially from the peel, tends to be associated with healthy digestion.&nbsp;



Experts point out that any improvement in digestion often has an indirect benefit on other organs, including the liver.



<h2 class="wp-block-heading" id="h-how-apples-fit-into-the-picture">How apples fit into the picture</h2>



<a href="https://www.mdpi.com/2076-3417/13/8/5112" target="_blank" rel="noreferrer noopener">Researchers</a> across different institutions have studied how apples might support better liver function. The fruit seems to help maintain balance in the body by reducing oxidative stress.&nbsp;



This simply means that apples offer a natural approach to curbing some of the harmful chemical reactions that occur in cells during ordinary life. Left unchecked, these reactions can lead to inflammation or a buildup of fats in the liver.



“Mechanistic studies and short-term randomized trials suggest higher intakes of dietary flavonoids may protect against nonalcoholic fatty liver disease,” wrote William Bell at the end of that research summary.



This line hints at a bigger story: the beneficial ingredients in <a href="https://www.earth.com/news/apple-orchards-face-compounding-threats-from-climate-change/" target="_blank" rel="noreferrer noopener">apples</a> appear to support a healthier liver, which could mean a simpler way to look after the body’s wellness without specialized supplements.



<h2 class="wp-block-heading" id="h-apples-and-their-protective-qualities">Apples and their protective qualities</h2>



Apples stand out partly because they supply two types of fiber: soluble and insoluble. Both forms can help with digestive rhythm. In addition, many of the vitamins and antioxidants in apples may assist the liver in cleaning out unwanted particles.&nbsp;



Researchers concur that the fiber and polyphenols present in apples <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4488768/#:~:text=Other%20studies%20indicated%20that%20apple,in%20the%20peel%20%5B150%5D.">help</a> lower cholesterol levels in the liver, as noted in their findings. Over time, that kind of health support might be very important for those facing potential liver issues.



Some <a href="https://exclusives.ca.uky.edu/2021/fcs/fruit-and-vegetable-peels-contain-many-nutrients#:~:text=Studies%20have%20found%20that%20a,an%20apple%20without%20its%20peel." target="_blank" rel="noreferrer noopener">nutritionists</a> highlight the fact that apples offer more nutrients with their peels on than with their peels removed, although slicing them or cooking them in different ways can still provide a decent nutrient load.&nbsp;



Whether it is a crisp snack on its own or baked with cinnamon, the apple holds plenty of vitamins that help round out any diet plan. 



Little choices, like adding this fruit to daily meals, can add up and contribute to a stronger defense against liver stress.



<h2 class="wp-block-heading" id="h-simplicity-that-fits-everyday-life">Simplicity that fits everyday life</h2>



There is also something comforting about apples. They are easy to pack in a bag, affordable, and versatile. Some people even blend them into smoothies or add small chunks to salads.&nbsp;



The fiber helps <a href="https://pubmed.ncbi.nlm.nih.gov/36193993/" target="_blank" rel="noreferrer noopener">curb hunger</a>, so it can keep energy levels steady between meals. This is especially handy for individuals aiming to maintain a healthy weight which, in turn, supports a more balanced metabolic state.



Apples also tend to pair well with other flavonoid-rich foods like berries, onions, and tea. Many of these items are part of standard grocery lists for people hoping to eat more wholesome and natural foods. By including more of them in one’s diet, it may be possible to encourage a more resilient body overall.



<h2 class="wp-block-heading" id="h-keeping-things-real">Keeping things real</h2>



Everything we do, from our breakfast options to our afternoon snacks, has a ripple effect inside the body. The liver, though rarely discussed, is a vital player in keeping us energized. But it can take a beating when we pile on the sugars, fats, or unbalanced meals.&nbsp;



Looking after it does not always require drastic changes or expensive supplements. A trip to the produce aisle, and the choice to snack on an apple or two, might give the <a href="https://www.earth.com/news/startling-connection-between-soda-and-liver-disease-revealed/" target="_blank" rel="noreferrer noopener">liver</a> the steady support it needs.



Many folks wonder if it makes sense to peel apples or avoid them altogether in certain health conditions. Most diet experts say that unless there is a specific medical reason, the peel should be eaten as it is filled with beneficial substances.&nbsp;



The only caveat is to wash apples well before eating them, especially if they are not organic, to remove any lingering residues. In the grand scheme, though, apples remain a humble champion for the liver.



<h2 class="wp-block-heading" id="h-putting-new-findings-to-good-use">Putting new findings to good use</h2>



Some people see the <a href="https://columbiasurgery.org/liver/liver-and-its-functions" target="_blank" rel="noreferrer noopener">liver</a> as a silent workhorse. It stores nutrients, cleans toxins, and supports daily vitality. But silence does not mean it needs less care. In fact, giving it the right nutrition might be the best path to feeling spry as the years roll on. 



While the research keeps evolving, many experts maintain that wholesome eating has yet to fall out of style, and apples fit beautifully into that philosophy.



Not everyone loves a raw piece of fruit, so sliced apples on top of oatmeal or applesauce with a dash of cinnamon can be just as helpful.&nbsp;



This everyday <a href="https://www.earth.com/news/eating-kiwifruit-immediately-significantly-improves-brain-health/" target="_blank" rel="noreferrer noopener">fruit delivers vitamins</a>, fiber, and special plant chemicals that support liver function over time. Once we take a moment to appreciate how these small steps add up, it is easier to say yes to a routine that includes more nutritious foods.



The study is published in <a href="https://www.sciencedirect.com/science/article/pii/S0002916524007913" target="_blank" rel="noreferrer noopener">The American Journal of Clinical Nutrition</a>.

Experts say this is the best fruit to eat for a healthier liver

Wild plants may hold the key to building resilient crops for a world that is increasingly impacted by climate change. As global temperatures rise and weather patterns shift, the search for hardy, adaptable crop varieties has become more urgent than ever. 



While our ancestors transformed many wild species into staple crops, could they have overlooked others with untapped potential? 



Scientists at the University of Southampton believe that certain wild or underutilized plants might be vital in future to designing crops that will withstand the challenges of a warming world.



<h2 class="wp-block-heading" id="h-a-rich-heritage-of-cultivation">A rich heritage of cultivation</h2>



The journey of cultivation is an ancient one. Nearly 12,000 years ago, our <a href="https://www.earth.com/news/our-hunter-gatherer-ancestors-did-much-more-gathering-than-hunting/" target="_blank" rel="noreferrer noopener">hunter-gatherer</a> ancestors became cultivators who selectively grew seeds from their best plants.



Over time, this led to hardier, more productive crops. Yet, not all wild species were deemed suitable for cultivation - some were left behind. 



Can these forsaken wild species offer us any insights today?



<h2 class="wp-block-heading" id="h-digging-into-the-potential-of-wild-plants">Digging into the potential of wild plants</h2>



In their recently published study in Trends in Ecology and Evolution, the Southampton team, including scientists from Oxford and Sheffield, and the Royal Botanical Gardens at Kew, propose that certain <a href="https://www.earth.com/news/billions-of-people-depend-on-wild-plant-and-animal-species/" target="_blank" rel="noreferrer noopener">wild species</a> possess traits that make them prime candidates for cultivation.



They’ve drawn on a wealth of past research to probe why certain wild species were preferred over others and how cultivated plants differ genetically from their wild antecedents.



“Tens of thousands of plant species are edible, yet just a few hundred have been <a href="https://www.earth.com/news/domesticating-plants-permanently-alters-their-microbiome/" target="_blank" rel="noreferrer noopener">domesticated</a> and a mere 15 species provide 90 percent of our calories,” stated Professor Mark Chapman of the University of Southampton, making a sobering point. 



“Hundreds of wild plants were collected during the Neolithic period by humans, but were later abandoned as food sources. We have explored which genetic or physical traits facilitated or constrained the domestication of wild species,” he added.



This glaring disparity begs the question - why so few?



<h2 class="wp-block-heading" id="h-traits-of-the-chosen-wild-plants">Traits of the chosen wild plants</h2>



The team identified three key factors that influence a plant's suitability for cultivation. 



First is plasticity - the ability of plants to adapt quickly to their environment and develop traits favored by humans, thus making them more practical for cultivation.



Second is genetic make-up, where simplicity plays a crucial role; traits governed by fewer genes are easier to modify. Thus simpler genetic programming makes it easier to change a plant's morphology to meet human needs.



Lastly, mutation rate is significant; plants that mutate more rapidly can evolve faster, potentially producing larger seeds or more palatable fruits over shorter timeframes.



<h2 class="wp-block-heading" id="h-planning-for-an-uncertain-future">Planning for an uncertain future</h2>



Understanding what led to the dominance of certain plant species in agriculture could be crucial in identifying new potential <a href="https://www.earth.com/news/can-we-predict-the-chaotic-response-of-crops-to-climate-change/" target="_blank" rel="noreferrer noopener">crops for a changing climate</a>. 



“When plants were first domesticated thousands of year ago, humans only knew the climate and weather conditions they would face at that present time," explained Professor Chapman.



"Now, using sophisticated climate modelling, we can predict how our world will warm and how our weather will change in the decades to come. This gives us the opportunity to think about the ways in which our crops will need to be resistant in the future."



The team’s research emphasizes that plants overlooked or underutilized in the past may hold valuable traits that offer new opportunities to develop crops better suited to future environmental challenges.



By applying selective breeding and precision breeding tactics, these underdogs might just become the crops for a warming world.



<h2 class="wp-block-heading" id="h-unlocking-the-potential-of-forgotten-crops">Unlocking the potential of forgotten crops</h2>



While the history of modern agriculture has been dominated by a very small pool of crops, many wild plants and their biodiversity have yet to be explored.



Many of these plants have extraordinary characteristics, including <a href="https://www.earth.com/news/old-growth-trees-more-tolerant-to-drought/" target="_blank" rel="noreferrer noopener">drought</a> resistance, pest tolerance, and the ability to grow in poor soils, all of which make them attractive candidates for a future of climate-resilient agriculture.



According to the <a href="https://www.southampton.ac.uk/" target="_blank" rel="noreferrer noopener">University of Southampton</a> team, advanced technologies such as genomics and precision breeding can unlock these traits.



By mapping the genomes of the wild relatives along with other, lesser-known crops, scientists can find genes responsible for desirable characteristics and incorporate them into new crop varieties.



This approach not only expands our agricultural repertoire but also provides insurance against the vulnerabilities of monoculture farming in an unpredictable climate.



The full study was published in the journal <a href="https://linkinghub.elsevier.com/retrieve/pii/S016953472400315X" target="_blank" rel="noreferrer noopener">Trends in Ecology &amp; Evolution</a>.

Domesticating wild plants may result in more resilient crops

Wild plants may hold the key to building resilient crops...

In our efforts to sustain the planet, one vital aspect that we have often failed to consider is the role of tree crops. 



Did you know that tree crops cover an astounding 183 million hectares worldwide? Yet, they remain largely overlooked in agricultural policies. 



<h2 class="wp-block-heading" id="h-the-potential-of-tree-crops">The potential of tree crops </h2>



Whether it's apples, cherries, olives, nuts, coffee, or cacao, tree crops offer much more than just a tasty snack or your morning caffeine boost.



A recently published study has highlighted their immense potential not only by feeding us globally but by safeguarding biodiversity, tackling climate change, and improving millions of lives worldwide. 



The international team of authors shared their findings in a Perspectives article published in the journal Nature Sustainability.



"In this Perspective, we highlight the potential of properly managed and incentivized perennial woody crops to support holistic sustainable development and urge scientists and policymakers to develop an effective agenda to better harness their benefits," wrote the researchers.



<h2 class="wp-block-heading" id="h-overlooked-role-of-tree-crops">Overlooked role of tree crops</h2>



<a href="https://www.earth.com/news/great-salt-lake-agriculture-is-draining-a-natural-wonder/" target="_blank" rel="noreferrer noopener">Agricultural</a> policies have traditionally focused on annual crops like wheat, rice, and sunflowers. These crops have a much shorter life cycle, typically completing germination to harvest in a year. 



While promoting sustainable practices for these crops is essential, their ecological benefits are limited. Their simpler vegetation and short harvest cycles don't offer the same long-term ecological benefits.



Tree crops, in contrast, are far more complex. They consist of multiple layers of vegetation, such as herbaceous plants, shrubs, and trees, creating stable ecosystems that support biodiversity when managed sustainably. 



"We’re missing an opportunity to leverage tree crops to address some of the biggest environmental and social challenges of our time," said Dr. Carlos Martínez-Núñez, a researcher at the <a href="https://www.ebd.csic.es/en" target="_blank" rel="noreferrer noopener">Doñana Biological Station</a>.



These systems not only provide habitats for various species but also contribute significantly to environmental protection.



<h2 class="wp-block-heading" id="h-benefits-beyond-food-production">Benefits beyond food production</h2>



Tree crops offer a range of environmental benefits. Their permanent root systems help prevent soil erosion and improve <a href="https://www.earth.com/news/world-soil-day-2024-protecting-our-planets-lifeline/" target="_blank" rel="noreferrer noopener">soil fertility</a>. The extensive leaf litter from these crops enriches the soil, making it more productive over time. 



Additionally, tree crops act as natural carbon sinks, sequestering greenhouse gases and aiding in climate change mitigation.



These crops also enhance habitat connectivity, allowing fragmented ecosystems to thrive and providing a buffer against the impacts of intensive agriculture. By improving ecosystem services and offering stable, year-round habitats, tree crops play an essential role in global biodiversity conservation.



Moreover, tree crops are less mechanized and demand more manual labor than other forms of agriculture. This makes them vital sources of employment in low- and middle-income countries, where they are widespread. 



"When managed properly, these agricultural systems can be a powerful tool for biodiversity conservation, climate change mitigation, and rural poverty alleviation," noted Dr. Martínez-Núñez.



<h2 class="wp-block-heading" id="h-a-call-for-action">A call for action</h2>



The study highlights the need for tailored policies and research to ensure <a href="https://www.earth.com/news/we-are-in-a-race-against-time-to-save-our-food-supply-from-climate-change/" target="_blank" rel="noreferrer noopener">sustainable management</a> of tree crops.



Dr. Elena Velado-Alonso, co-author of the study and researcher at Göttingen University’s <a href="https://www.uni-goettingen.de/en/596513.html" target="_blank" rel="noreferrer noopener">Functional Agrobiodiversity and Agroecology Group</a>, emphasized the importance of context-specific measures.



"Tree cropping areas overlap with most of the world’s biodiversity-rich areas, making them key to conservation," said Dr. Velado-Alonso. "However, local practices and landscape-scale measures adapted to different contexts are needed."



To maximize the contribution of tree crops to global sustainability, the research team calls for implementing regulations, financial incentives, and policies that support improved agricultural practices. 



These steps could harness tree crops' full potential in addressing key environmental and social challenges.



<h2 class="wp-block-heading" id="h-rethinking-agriculture-with-tree-crops">Rethinking agriculture with tree crops</h2>



This call to action marks a crucial step in rethinking agriculture's role in creating a more <a href="https://www.earth.com/news/climate-and-agriculture-are-locked-in-a-destructive-feedback-loop/" target="_blank" rel="noreferrer noopener">sustainable and equitable world</a>. 



By embracing the benefits of tree crops and promoting sustainable practices, we can take significant strides toward achieving the United Nations' <a href="https://sdgs.un.org/goals" target="_blank" rel="noreferrer noopener">Sustainable Development Goals</a>. These crops are not just a source of food and income - they are a powerful tool for environmental protection and social progress.



With more attention, research, and support, tree crops could become the cornerstone of sustainable agriculture, helping to address the climate crisis, conserve biodiversity, and uplift communities worldwide.



The study is published in the journal <a href="https://www.nature.com/articles/s41893-024-01483-8" target="_blank" rel="noreferrer noopener">Nature Sustainability</a>.

Tree crops: A path to feeding the world and saving the planet

In our efforts to sustain the planet, one vital aspect...

Could you imagine happening upon an orchid that looks familiar but has a unique difference that makes you wonder if it is a new species? 



That’s exactly what happened during a study at Norfolk Island National Park. This unexpected find sparked a collaborative effort to uncover the orchid’s true identity.



<h2 class="wp-block-heading" id="h-a-glimpse-into-the-field-the-discovery">A glimpse into the field - the discovery</h2>



While conducting botanical research at Norfolk Island National Park, Dr. Heidi Zimmer, an orchid researcher at the <a href="https://www.anbg.gov.au/cpbr/herbarium/" target="_blank" rel="noreferrer noopener">Australian National Herbarium</a> (ANH), and botanist Dr. Mark Clements were guided by the local expertise of Joel Christian, Mel Wilson, and Allie Andersen. 



In the late afternoon light, the team’s efforts paid off when Dr. Clements spotted a peculiar orchid growing on a tree branch. 



Something about <a href="https://www.earth.com/wp-content/uploads/2025/01/new-orchid-species_cupcake_Adelopetalum-argyropus_credit-Heidi-Zimmer_1m.jpg" target="_blank" rel="noreferrer noopener">the orchid looked different</a>, prompting Dr. Zimmer to collect a sample to take back to the ANH for further study.



<h2 class="wp-block-heading" id="h-investigating-the-new-orchid">Investigating the new orchid</h2>



The orchid was identified as belonging to the genus Adelopetalum, but its exact classification was unclear.



Recognizing its potential as a <a href="https://www.earth.com/news/dna-technology-will-accelerate-the-pace-of-plant-species-discovery/" target="_blank" rel="noreferrer noopener">new species</a>, Zimmer and Clements collaborated with a broader team of experts, including retired ANH botanist David Jones, who served as the lead researcher. 



“This was a wonderfully collaborative project with folks from Lord Howe Island and Norfolk Island, and Australian botanists and taxonomists all working together,” enthused Dr. Zimmer, 



<h2 class="wp-block-heading" id="h-analyzing-the-new-adelopetalum-orchid">Analyzing the new Adelopetalum orchid</h2>



To determine whether this orchid was indeed a new species, the team began an exhaustive process. 



They compared the Norfolk Island specimen to descriptions of orchid species in scientific journals, specimens housed in the Australian National Herbarium - which contains approximately 75,000 specimens - and orchids preserved in herbaria across Australia and internationally.



This analysis utilized both physical specimens and digitized collections, allowing the researchers to examine a vast array of potential matches.



The research revealed a surprising result: the orchid species previously identified as Adelopetalum argyropus was not a single species but three distinct ones.



“We recognized that the Norfolk Island species was different because the <a href="https://www.earth.com/news/flowers-blooming-92-days-earlier-due-to-climate-change/" target="_blank" rel="noreferrer noopener">flower</a> did not have a yellow labellum - no giant bright yellow tongue,” explained Dr. Zimmer.



Even for researchers in training, the differences were clear when dissecting the flowers and examining herbarium specimens.



<h2 class="wp-block-heading" id="h-the-findings-a-new-species">The findings - a new species</h2>



As per taxonomic rules, the species from Norfolk Island retained the name Adelopetalum argyropus because it was the first described, dating back to 1833.



The two newly identified species were named Adelopetalum howense, which was found on Lord Howe Island, and Adelopetalum continentale, which was found on mainland Australia.



The team speculated that these orchids’ seeds, so fine and dust-like, were likely carried by the wind to their distant <a href="https://www.earth.com/news/fossil-reveals-how-plants-use-winged-seeds-to-expand-their-habitats/" target="_blank" rel="noreferrer noopener">habitats</a>.



This discovery highlights the interconnectedness of ecosystems and the role of natural dispersal mechanisms in shaping biodiversity.



<h2 class="wp-block-heading" id="h-publishing-the-discovery-the-description">Publishing the discovery - the description</h2>



The researchers published their findings in Phytotaxa, giving details of the botanical features of the new species.



The paper described the Norfolk Island orchid’s pseudobulbs as “broadly oblong to obconical or turbinate, similar to a cupcake, with shallow grooves and scurfy surfaces from remnants of bracts.” 



These detailed descriptions provide a foundation for further study and <a href="https://www.earth.com/news/machine-learning-identifies-4300-types-of-endangered-orchids/" target="_blank" rel="noreferrer noopener">conservation efforts</a>.



<h2 class="wp-block-heading" id="h-understanding-the-impact-the-assessment">Understanding the impact - the assessment</h2>



Orchids are among the plant families most at <a href="https://www.earth.com/news/despite-their-incredible-adaptability-orchids-are-disappearing/" target="_blank" rel="noreferrer noopener">risk of extinction</a>, particularly those confined to habitats that are small in extent.



The three new species face significant threats due to their limited distribution and environmental pressures.



Dr. Zimmer emphasized the importance of naming and describing new species as part of broader conservation efforts. 



“The purpose of naming and describing new orchid species is to build a checklist of Australian orchids so people can conserve them. We think there are risks for these three new species," Dr. Zimmer explains.



"This is because the species on Norfolk and Lord Howe Islands are both confined to small islands and the one on continental Australia was badly impacted by the 2019–2020 bushfires."



This discovery highlights the power of collaboration and the enduring mysteries of nature. It’s a reminder of how much there is still to uncover and protect in our world.



The full study was published in the journal <a href="https://phytotaxa.mapress.com/pt/article/view/phytotaxa.678.1.9" target="_blank" rel="noreferrer noopener">Phytotaxa</a>.

Scientists are transforming chocolate into a functional food by infusing it with probiotics and prebiotics, aiming to create a treat that satisfies cravings while supporting gut health. 



The challenge lies in maintaining chocolate's beloved texture and flavor while adding health benefits.



<figure class="wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"><div class="wp-block-embed__wrapper">

</div></figure>



Probiotics - beneficial microbes that balance gut bacteria and aid digestion - are typically fragile and can be destroyed by stomach acid or processing. 



Prebiotics act as food for these microbes, helping them thrive. Together, they form "synbiotics," a powerful health combination.



Researchers Smriti Gaur and Shubhi Singh from India's Jaypee Institute of Information Technology took an innovative approach, using natural prebiotics like corn and honey instead of complex processing methods. 



They created five chocolate varieties: a control and four synbiotic versions containing different combinations of prebiotics, probiotics (Lactobacillus strains), and flavor enhancers (cinnamon or orange).



Laboratory simulations of human digestion showed the probiotics remained viable for over five hours, suggesting they could survive long enough to benefit gut health.



Taste tests were positive, with researchers particularly enjoying the orange-flavored variety, describing it as having "vibrant citrus notes" complementing the "rich cocoa" with a "luxurious" texture.



This research represents just the beginning. With further refinement of strains, textures, and flavors, chocolate could evolve beyond mere indulgence to become a functional food that nourishes while it delights.



The study is published in the journal <a href="https://pubs.acs.org/doi/10.1021/acsfoodscitech.4c00741" target="_blank" rel="noreferrer noopener">ACS Food Science &amp; Technology</a>.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Nushagak Bay, a large estuary in southwest Alaska. Nushagak runs mainly north to south and exits in Bristol Bay, a large body of water in the Bering Sea.



"The bay is primarily fed by the Nushagak River, which begins in the Alaska Range and flows southwest approximately 450 km. The bay is also fed by several additional rivers including the Wood, Igushik, Snake and Weary rivers," says ESA.



"The dark colors of the Nushagak River are most likely due to tannins or lignins (chemical substances found in plants). Tannins and lignins from roots, leaves, seeds, bark and soil can leach into the water and give it a brown or even black colour. The sediments then flow southwards where it is mixed with the bluer waters of the bay."

Today's Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> (ACS) reveals that proteins on flu viruses are actually flexible, tilting and waving in a “breath-like” motion. According to the experts, these proteins could be used to better defend against the flu.



"The main antigenic targets of influenza virus are two surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA). Whereas the structural and dynamical properties of both glycoproteins have been studied previously, the understanding of their plasticity in the whole-virion context is fragmented," wrote the researchers.



To investigate, the team conducted detailed simulations of the influenza A H1N1 virion, or the swine flu. The experts concluded that the visualizations show many new vulnerable states of flu viruses, which could improve future vaccines and antiviral drugs.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Lake Trasimeno, which is located west of Perugia in central Italy. It is the fourth largest lake in the country. While Trasimeno’s water level varies, it has a maximum depth of approximately six meters.&nbsp;



"In this Copernicus Sentinel-2 image, captured on 6 August 2022, the lake’s emerald green colour is likely due to the presence of phytoplankton. Streaks in the water, particularly visible in the west, indicate the presence of soil and sediments which have been stirred up by winds. Dark colored waters in the southern part of the lake indicate a presence of submerged and floating macrophytes (aquatic plants) as well as algae," says ESA.



"Surrounded by hills on three sides, Trasimeno is subject to heavy storms created by winds, especially from the north and west. There are three islets in the lake: Maggiore, Minore and Polvese (the largest). The lake’s shores are sparsely inhabited with only two popular villages: Castiglione del Lago and Passignano sul Trasimeno."



"Italy is experiencing its worst drought in 70 years which has affected drinking water supplies, hydroelectric power and agricultural production. High temperatures, hot winds and lack of rainfall are the main causes of drought in the Umbrian region which saw Lake Trasimeno’s drop 1.3 m, reaching the limit of the hydrometric zero in July 2022."

Today's Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> describes a new self-powered nanosensor that can instantly detect mercury contamination with the tap of a finger.&nbsp;



The oxidized form of mercury can be harmful when it is ingested through contaminated water or food. This makes it necessary for experts to develop sensors that can quickly and accurately detect the presence of mercury.&nbsp;



Zong-Hong Lin and colleagues have now created a triboelectric nanosensor (TENS) that can detect mercury by simply by touching a sample. According to the researchers, their TENS could serve as the basis for similar devices to safely and remotely monitor other pollutants.

Today’s Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> explores the ability of salt to transform the way that foods and beverages taste. Salt is known to cover up undesirable flavors, such as bitterness in coffee or beer, but how exactly does sodium chloride change the taste of other compounds?



One previous study showed that, not only does salt suppress bitterness, but also enhances sweetness and sourness. Another study revealed that bitterness reduction by salt seems to be happening at the tongue receptor level as well as in the brain.&nbsp;



While it is known that salt taste is mediated by the presence of sodium channels in the form of taste buds, experts believe that there is also an unknown receptor responsible for how we taste salt that has not yet been identified.&nbsp;

'The weather of Santiago resembles the Mediterranean climate with dry and warm summers with temperatures reaching up to 35°C (from October to March) and cool and humid winters that can drop to 0°C (from April to September)."



"The city lies in the centre of the country’s central valley around 80 km from the Pacific Ocean to the west and borders Argentina to the east. A tiny part of Argentina is visible in the top-right corner of the image where the mountain crest of the Andes Mountains acts as a divider between the two countries," says ESA.

Astronomers at <a href="https://www.jhu.edu/">Johns Hopkins University</a> have created an interactive map of the universe, including the actual position and real colors of 200,000 galaxies. The map allows the public to access data that was previously only available to scientists.



The map was developed using data collected by the Sloan Digital Sky Survey. For over two decades, a telescope in New Mexico was aimed at slightly different locations to capture the night sky.&nbsp;



"Growing up I was very inspired by astronomy pictures, stars, nebulae and galaxies, and now it's our time to create a new type of picture to inspire people," said map creator Brice Ménard, a professor at Johns Hopkins. "Astrophysicists around the world have been analyzing this data for years, leading to thousands of scientific papers and discoveries. But nobody took the time to create a map that is beautiful, scientifically accurate, and accessible to people who are not scientists. Our goal here is to show everybody what the universe really looks like."



"In this map, we are just a speck at the very bottom, just one pixel. And when I say we, I mean our galaxy, the Milky Way which has billions of stars and planets. We are used to seeing astronomical pictures showing one galaxy here, one galaxy there or perhaps a group of galaxies. But what this map shows is a very, very different scale."



"From this speck at the bottom, we are able to map out galaxies across the entire universe, and that says something about the power of science."



The <a href="https://mapoftheuniverse.net/">interactive map</a> is available online, where it can be downloaded for free.

Lesotho: Africa's "Kingdom in the Sky" Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features northwest Lesotho in South Africa.



According to ESA, Lesotho is the only nation in the world that lies completely above 1,000 m in elevation. The country is famous for its tall mountains and narrow valleys, and is known as Africa's "Kingdom in the Sky."



Out of a population of around two million people, about 80 percent live in rural areas. More than 75 percent of these people are engaged in <a href="https://www.earth.com/news/climate-change-will-have-a-global-impact-on-agriculture/">agriculture</a>, including rainfed cereal production and animal grazing.&nbsp;



ESA reports that the country’s agricultural system faces a growing number of issues, with climate-related vulnerabilities such as drought, floods and extreme temperatures occurring more frequently. 



Diamonds are amongst the minerals found in the mountains. Indeed, Lesotho can truly be called the Kingdom in the Sky. Beautiful, culturally rich, safe, affordable, and easily accessible from Durban and Johannesburg, mountainous Lesotho is a vastly underrated travel destination. the Kingdom of Lesotho (Sotho: 'Muso oa Lesotho) is an enclaved country in southern Africa. It is just over 30,000 km2 (11,583 sq mi) in size and has a population of around 2 million.

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Dublin, the capital and largest city of Ireland. Beyond its pub culture, Dublin is known as a modern culinary destination and a UNESCO City of Literature.



"Dublin is located near the midpoint of Ireland’s east coast in the province of Leinster. The city, which covers an area of around 115 square kilometers, is bordered by the Dublin Mountains, a low mountain range to the south, and is surrounded by flat farmland to the north and west," says ESA.



"The city straddles the River Liffey, which rises in the Wicklow Mountains and flows around 80 kilometers eastwards through the city of Dublin, in which it is canalised and bordered with quays. It then empties into Dublin Bay, an arm of the Irish Sea."



Dublin has an abundance of green spaces, including one of the largest enclosed public parks in any European capital city. Phoenix Park, which was originally formed as a royal hunting park in the 1660s, includes 707 hectares of green space.

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the province of Zaragoza in northeast Spain. The image was captured by the Copernicus Sentinel-2 mission.



"Together with the provinces of Huesca and Teruel, Zaragoza formed the old kingdom of Aragon. Its capital, also called Zaragoza (not visible in this image) is home to around half of Aragon’s population," says ESA.



"The Ebro River can be seen winding its way through the province from west to east in this image. Between its source in the Cantabrian Mountains in the northwest and its delta on the Mediterranean coast, the Ebro River is fed by more than 200 tributaries as it flows 910 km across much of northern Spain."



Since rainfall is very scarce in this region, irrigation in the Ebro basin is critically important. In the valleys surrounding the Ebro River, many fields are used for growing crops such as corn, wheat, and barley.

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> reveals the evolution of the Columbia Glacier in southeastern Alaska. Columbia is among the fastest shrinking glaciers in the world, and the video documents its rapid retreat over the years.&nbsp;



Columbia Glacier is a large, multi-branched calving glacier that flows out of the Chugach Mountains to the Prince William Sound.&nbsp;



According to USGS, Columbia had a long history of stability prior to 1980, with a length 41 miles, and small, short-lived advances or retreats.



In the years since 1980, however, satellite images have captured Columbia’s alarming retreat. By using false-color images, scientists can distinguish between snow and ice, open water, vegetation, and rocky debris on the glacier’s surface.



The series of false-color images featured in today's video were acquired over the span of 35 years. You can see that by 2021, the glacier’s main branch had retreated about 15 miles from its initial position.



The Columbia Glacier has also lost more than 50 percent of its volume, mostly due to calving. <a href="https://www.earth.com/video/nasa-reveals-3d-visual-of-an-atmospheric-river/">NASA</a> reports that while climate change likely started the retreat, mechanical processes kept the disintegration going.



The NASA images are provided by Jesse Allen, Robert Simmon, Joshua Stevens, and Lauren Dauphin using data from Landsat satellites, from the U.S. Geological Survey, and data from MODIS on NASA’s Terra satellite. The structure of Columbia’s moraine played a large role in the stability of the glacier before 1980. 



Like other tidewater glaciers, the Columbia built up a moraine over time, and the mixture of ice and rock functioned like a dam keeping out the sea. It was supported on one end by the shoreline and by the underwater terminal moraine at the other.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the Pyrenees Mountains, which form a natural boundary between France and Spain in southwest Europe.



The mountain range is 430 kilometers in length. It stretches from the Mediterranean Sea on the east to the Atlantic Ocean on the west.



At an elevation of 3404 meters, Pico de Aneto is the highest mountain peak in the Pyrenees, and the third-highest peak in Spain. Pico de Aneto is located in the Posets-Maladeta Natural Park, which spans more than 82,000 acres.&nbsp;



"Geological studies have revealed that the Pyrenees Mountains have been around for longer than the Alps, with their sediments first deposited in coastal basins during the Paleozoic and Mesozoic eras," reports ESA.



"The entire mountain range formed due to the upwelling of large sedimentary rocks by the collision of the Iberian and the Eurasian plate around 100 to 150 million years ago, followed by intense erosion from ice and water."



The western Pyrenees receive more precipitation due to moisture blowing in from the Atlantic Ocean. The mountain range contains many lakes, several small glaciers, and some of the highest waterfalls in Europe.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes two exoplanets that are orbiting a star 218 light-years away. A team of researchers led by the University of Montreal has found evidence that these planets are "water worlds."



The experts used data from NASA’s Hubble and Spitzer Space Telescopes. They discovered that exoplanets Kepler-138 c and Kepler-138 could be composed largely of water.



"We previously thought that planets that were a bit larger than Earth were big balls of metal and rock, like scaled-up versions of Earth, and that's why we called them super-Earths," explained study co-author Björn Benneke.&nbsp;



"However, we have now shown that these two planets, Kepler-138 c and d, are quite different in nature and that a big fraction of their entire volume is likely composed of water. It is the best evidence yet for water worlds, a type of planet that was theorized by astronomers to exist for a long time."

Today’s Video of the Day from the <a href="https://welcome.miami.edu/">University of Miami</a> Rosenstiel School of Marine and Atmospheric Science explores how changes in water temperatures have affected tiger shark habitats and movements in the North Atlantic Ocean. The study reveals that rising temperatures have caused the sharks to shift toward the poles over the past 40 years.



“Tiger shark annual migrations have expanded poleward, paralleling rising water temperatures,” explained study lead author Neil Hammerschlag. “These results have consequences for tiger shark conservation, since shifts in their movements outside of marine protected areas may leave them more vulnerable to commercial fishing.”



The researchers analyzed nine years of tracking data from satellite-tagged tiger sharks, combined with four decades of conventional tag and recapture data provided by National Oceanic and Atmospheric Administration (NOAA) Cooperative Shark Tagging Program.



The experts found that during the last decade of record heat, for every one-degree Celsius increase in water temperatures, tiger sharks migrated further poleward by over 400 kilometers. They also migrated two weeks earlier than usual to waters off the northeastern coast of the United States.



“Given their role as apex predators, these changes to tiger shark movements may alter predator-prey interactions, leading to ecological imbalances, and more frequent encounters with humans,” concluded Professor Hammerschlag.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> is focused on the melt ponds that emerge during the spring and summer on the Greenland Ice Sheet, which is the largest ice mass in the northern hemisphere.



"Melt ponds are vast pools of open water that form on both sea ice and ice sheets and are visible as turquoise-blue pools of water in this Copernicus Sentinel-2 image," says ESA.



"When snow and ice melts atop glaciers, water flows in channels and streams and collects in depressions on the surface. These melt ponds can speed up the melting of the surrounding ice since they greatly reduce the ice’s ability to reflect sunlight."



"This can create a positive feedback where an increasing number of melt ponds absorb more heat which causes ice cover to melt even faster."



According to ESA, Greenland has been hit with a late-season heatwave that began in early September. This caused the type of melt event that usually occurs in the middle of summer.



"In a recent paper published in Nature Climate Change, scientists found that major sea-level rise from the melting of the Greenland ice cap is now ‘inevitable’ even if the burning of fossil fuels were to halt overnight," says ESA. "Using satellite observations of Greenland ice loss and ice cap from 2000 to 2019, the team found the losses will lead to a minimum rise of 27 cm regardless of climate change."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes a new map of Mars that is providing insight into the planet’s watery past. The map also reveals where future missions could safely land on Mars.&nbsp;



The map has been created over the last decade using observations of water-rich rocks and mineral deposits. The images were captured by ESA’s Mars Express and NASA’s Mars Reconnaissance Orbiter.



"A big surprise is the prevalence of these minerals, with the map revealing hundreds of thousands of water-affected locations in the oldest parts of the planet," says ESA. "The new data will help answer exciting questions about Mars’ climate history, whether water was globally persistent or confined to short, intense episodes, and whether the conditions were ever suitable for life."



"Specifically, the map shows the locations and abundances of aqueous minerals. These are from rocks that have been chemically altered by the action of water in the past, and have typically been transformed into clays and salts."



According to John Carter of the Institut d’Astrophysique Spatiale (IAS), our collective understanding of Mars has been oversimplified. He explained that planetary scientists have tended to think that only a few types of clay minerals on Mars were created during its wet period, then as the water gradually dried up, salts were produced across the planet.



The new map shows that the composition of Mars is much more complicated than what we thought. For example, while many salts formed after Martian clays, there are some salts that are presumed to be older than some of the clays.&nbsp;



“The evolution from lots of water to no water is not as clear cut as we thought, the water didn’t just stop overnight. We see a huge diversity of geological contexts, so that no one process or simple timeline can explain the evolution of the mineralogy of Mars. That’s the first result of our study. The second is that if you exclude life processes on Earth, Mars exhibits a diversity of mineralogy in geological settings just as Earth does,” said Carter.

Today's Video of the Day from the <a href="https://www.stowers.org/">Stowers Institute for Medical Research</a> describes how cavefish adapted to a sedentary lifestyle over tens of thousands of years. 



The experts found that the muscle metabolism of cavefish has been genetically reprogrammed over time. As a result, the animals have experienced major changes in their morphology and behavior. Despite these changes, however, the cavefish remain healthy and fit.



The research may provide new clues about the evolutionary consequences of prolonged physical inactivity in humans.&nbsp;



“It’s no surprise that people are moving less and less as technology has advanced,” said Rohner. “With cavefish, we have a unique system where we can study what might happen if people remained couch potatoes over very, very long periods of time.”

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> some of the most incredible waves in the world, as seen by Landsat satellites.



"With more than 370,000 miles of coastline on Earth, there are plenty of places where epic waves build up, curl over, and hurtle toward the shore.- much to the thrill of surfers," says NASA. "There are some places where these waves are so magnificent that they can be seen from space."



"With the broad perspective of satellites, we can see how these iconic waves develop into the world’s tallest, longest, fastest, and heaviest."
