Anolis roosevelti, also known commonly as Roosevelt's giant anole or the Culebra Island giant anole, is an extremely rare or possibly extinct species of lizard of the genus Anolis in the family Dactyloidae. The species is native to the Virgin Islands and Vieques. The Culebra Island giant anole is a member of a group of large tree canopy-dwelling lizards collectively termed "giant anoles" to distinguish them from their smaller relatives, also in the genus Anolis. The lizard is brownish gray with two lines on each side of the body. It has a gray throat fan that is bordered on the lower rear quarter by light yellow. The tail is yellowish brown and the belly is whitish in color. Adult males have a deeply scalloped fin along most of the tail. The body measures about 6.5 in (16.5 cm) and the tai

The narrow sawfish, also known as the pointed sawfish or knifetooth sawfish, is a species of sawfish in the family Pristidae, part of the Batoidea, a superorder of cartilaginous fish that include the rays and skates. Sawfish display a circumglobal distribution in warm marine and freshwater habitats. Their extant biodiversity is limited to five species belonging to two genera. The sawfishes are characterised by the long, narrow, flattened rostrum or extension on their snout. This is lined with sharp transverse teeth, arranged in a way that resemble the teeth of a saw and are used for killing prey. It is found in the shallow coastal waters and estuaries of the Indo-West Pacific, ranging from the Red Sea and the Persian Gulf to southern Japan, Papua New Guinea and northern Australia.

It is an inhabitant of the southwest mainland of Western Australia and some offshore islands. It is a member of the order Dasyuromorphia, and the only member of the genus, Parantechinus. The dibbler is a small, nocturnal carnivore with speckled fur that is white around the eyes. Brown antechinus are mostly nocturnal and is arboreal. During warm periods these marsupials live in solitary nests and occupy their own home ranges. As temperatures drop, both males and females stay together in nests with up to 18 animals. Their nests are not stable and antechinus may change nests. Females usually nest alone to rear young.Most dibblers (Parantechinus apicalis) live in heathland in southwest WA, however they have an island population on the west Australian coast in which the males die off while the main population doesn't, while savanna populations of northern quolls (Dasyurus hallucatus) have zero male survival to breed again but no apparent immune collapse that triggers the die-off.

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>.

New orchid species discovered resembles a small cupcake

Could you imagine happening upon an orchid that looks familiar...

When people think about glowing mushrooms, like the newly discovered species Mycena crocata, they often imagine tropical rainforests where such exotic wonders may be more commonly found. 



However, bioluminescent fungi are not limited to tropical regions - they also live in unexpected places.



In Zurich, artists Heidy Baggenstos and Andreas Rudolf have dedicated more than ten years to studying and showcasing these glowing organisms. 



Their work highlights the beauty and presence of bioluminescent fungi close to home, and proves that extraordinary natural phenomena can be found even in familiar surroundings.



"We want to show that these bioluminescent mushrooms are present in Swiss forests and that we do not have to travel far to find them," said Baggenstos.



<h2 class="wp-block-heading" id="h-mycena-crocata-glowing-mushrooms">Mycena crocata - glowing mushrooms</h2>



One evening, while exploring a forest in Zurich’s Albisrieden neighborhood, the duo spotted green light through their camera. 



"Nowadays we always have our mobile phones or a flashlight, but to see bioluminescence in the forest, it has to be pitch black," Rudolf explained.



Initially, they believed the glowing <a href="https://www.earth.com/news/fungi-can-think-and-make-smart-decisions-without-a-brain/" target="_blank" rel="noreferrer noopener">fungi</a> to be Mycena haematopus. Upon closer investigation in their studio, however, they identified it as Mycena crocata, the saffron drop bonnet mushroom. 



This species, known for its saffron-colored milk, had never been described as bioluminescent before.



The artists documented their findings with photographs and light measurements, uncovering this hidden brilliance. 



In darkness, the mycelium - the underground network of the mushroom - emits a green glow that even causes decaying wood to light up.



Under ideal conditions, their cultivated mycelia glowed for 164 days.



<h2 class="wp-block-heading" id="h-crossing-art-and-science">Crossing art and science</h2>



Collaborating with mycologist Renate Heinzelmann from the Swiss Federal Institute for Forest, Snow, and Landscape Research (<a href="https://www.wsl.ch/en/" target="_blank" rel="noreferrer noopener">WSL</a>), the artists published their discovery in&nbsp;Mycoscience. 



"Most of the experiments were conducted by the artists. They collected the samples, took the photographs, and made the light measurements," Heinzelmann said, praising their dedication.



Through their research, the artists discovered that the fruiting body (the mushroom itself) of Mycena crocata emits little to no light. 



<figure class="wp-block-image aligncenter size-full"><a href="https://www.earth.com/wp-content/uploads/2025/01/glowing-mushroom-species_Mycena-crocata_bioluminescence_credit-Baggenstos-Rudolf_1m.jpg" target="_blank" rel="noreferrer noopener"><img src="https://www.earth.com/wp-content/uploads/2025/01/glowing-mushroom-species_Mycena-crocata_bioluminescence_credit-Baggenstos-Rudolf_1s.webp" alt="Mycena crocata in the light (left) and in darkness (right).

The bioluminescence from the mycelium makes the wood glow. Credit: Baggenstos/Rudolf</figcaption></figure>



Instead, the underground mycelium - the root-like network of the <a href="https://www.earth.com/news/scientists-all-fungi-matter-not-just-mushrooms/" target="_blank" rel="noreferrer noopener">fungus</a> - is the primary source of its bioluminescence.



This glowing mycelium is capable of lighting up the decaying wood it grows on. When the wood is split open in the dark, it emits a green glow, which can last for up to four hours before gradually fading as the wood dries. 



This fascinating discovery highlights how the less-visible parts of fungi can hold some of their most extraordinary features.



<h2 class="wp-block-heading" id="h-mystery-of-glowing-fungi">Mystery of glowing fungi</h2>



Bioluminescence in <a href="https://www.earth.com/news/plants-and-fungi-communicate-using-a-silent-language/" target="_blank" rel="noreferrer noopener">fungi</a> happens because of a chemical reaction. A substance called&nbsp;luciferin&nbsp;reacts with an enzyme called&nbsp;luciferase. 



This reaction creates an unstable product that gives off energy as light, allowing the fungi to glow. Unlike other glowing effects like fluorescence, this process doesn’t need light or energy from outside sources; it happens naturally within the fungi.



Although scientists know how this reaction works, they are still unsure why fungi glow. One idea is that the light attracts insects, which might help spread the fungal spores.



However, this doesn’t fully explain the glow of the mycelium, which is hidden underground and doesn’t interact with insects. This mystery suggests there might be another, as yet unknown reason for fungal bioluminescence.



"It seems that bioluminescence has been maintained for a long time, so we assume it has some function," Heinzelmann says. "But it's still a mystery."



<h2 class="wp-block-heading" id="h-mycena-crocata-and-swiss-forests">Mycena crocata and Swiss forests</h2>



The discovery of&nbsp;Mycena crocata&nbsp;as a glowing, bioluminescent fungus highlights how much we still don’t know about the <a href="https://www.earth.com/news/secrets-of-fungi-diversity-can-be-pulled-out-of-thin-air/" target="_blank" rel="noreferrer noopener">natural world</a> around us. Local ecosystems hold countless secrets waiting to be explored. 



Bioluminescent fungi, for instance, have fascinated humans for thousands of years. Aristotle described their glow as a “cold fire” over 2,000 years ago, and even now, their mysteries continue to intrigue scientists.



According to mycologist <a href="https://www.wsl.ch/en/staff/heinzelm/" target="_blank" rel="noreferrer noopener">Renate Heinzelmann</a>, the field of bioluminescence is still in its early stages. She believes that as more people study fungi, more glowing species will be uncovered. "Bioluminescence is under-researched, and the more people look, the more they will find," she states.



The collaborative work of artists Heidy Baggenstos and Andreas Rudolf with scientists demonstrates how blending art and science can reveal nature’s hidden marvels. 



Their discovery serves as a powerful reminder that extraordinary phenomena aren’t always far away - they might be right in our local forests, waiting for someone curious enough to notice them.



The study is published in the journal <a href="https://www.jstage.jst.go.jp/article/mycosci/65/4/65_MYC633/_article" target="_blank" rel="noreferrer noopener">Mycoscience</a>.

New species of glowing mushrooms discovered

When people think about glowing mushrooms, like the newly discovered...

Polyphenols are natural compounds found abundantly in fruits, vegetables, tea, <a href="https://www.earth.com/news/adding-coffee-grounds-during-the-construction-process-could-reinforce-buildings/">coffee</a>, and other plant-based foods. They have gained increased recognition in the recent past for their potential health benefits.&nbsp;



These vibrant plant chemicals are thought to support heart health, enhance metabolism, and sharpen cognitive function, making them an intriguing area of research for those seeking ways to <a href="https://www.earth.com/news/morning-coffee-drinkers-have-a-lower-risk-of-heart-disease-and-death/" target="_blank" rel="noreferrer noopener">maintain overall wellness</a>.



<h2 class="wp-block-heading" id="h-broad-range-of-benefits-from-polyphenols">Broad range of benefits from polyphenols</h2>



Polyphenols have been explored for their potential to enhance health in numerous ways, yet much about them remains to be discovered. “Green tea and its bioactive components, especially polyphenols, possess many health-promoting and disease-preventing benefits … [but] have not been well studied,” as one <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8234133/" target="_blank" rel="noreferrer noopener">study</a> noted. 



Despite these gaps in understanding, researchers are increasingly intrigued by their possibilities. Studies suggest that polyphenols could play a role in supporting healthy blood pressure, improving skin health, and even aiding in waist size management.&nbsp;



According to <a href="https://profiles.imperial.ac.uk/f.amati" target="_blank" rel="noreferrer noopener">Dr. Federica Amati</a> from the School of Public Health at <a href="https://www.imperial.ac.uk/school-public-health/" target="_blank" rel="noreferrer noopener">Imperial College London</a>, these compounds go beyond traditional nutrients like fiber and vitamins, and offer a fascinating glimpse into the complex chemistry of the plants we eat.



<h2 class="wp-block-heading" id="h-colors-and-tastes">Colors and tastes</h2>



<a href="https://www.earth.com/news/what-you-eat-can-literally-change-the-world/">Plant foods</a> vary in appearance. Some have bright or deep pigments, while others boast a bitter flavor or a peppery kick. That color or pungent quality sometimes indicates a higher presence of polyphenols.&nbsp;



Black olives, deep purple eggplants, and richly colored spinach are believed to contain helpful substances. Tea, coffee, and dark chocolate are also recognized for contributing certain polyphenols, though they shouldn’t be seen as cure-alls.



Polyphenols are a subset of <a href="https://www.nal.usda.gov/human-nutrition-and-food-safety/food-composition/phytonutrients#:~:text=What%20are%20Phytonutrients%3F,other%20types%20of%20phytonutrients%20below." target="_blank" rel="noreferrer noopener">phytonutrients</a>. This wide-ranging family of molecules includes flavonoids, flavanones, lignans, and more. 



Some research highlights the potential of specific varieties, such as <a href="https://www.earth.com/news/drinking-tea-every-day-proven-to-delay-biological-aging-in-humans/" target="_blank" rel="noreferrer noopener">green tea</a> polyphenols, resveratrol in red wine, catechins in tea, and ellagic acid in walnuts. Scientists are still mapping how each type interacts with the body.



<h2 class="wp-block-heading" id="h-metabolic-and-heart-support">Metabolic and heart support</h2>



Several studies have examined whether consuming more polyphenols aligns with measurements tied to heart wellness, weight control, and broader metabolic function.&nbsp;



One <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8401650/" target="_blank" rel="noreferrer noopener">review</a> found that foods containing green tea polyphenols might help sustain immune function and manage inflammatory activity. Such findings have led many people to embrace green tea in their daily routine.



Although caution is wise, especially when interpreting any single study, experts agree on the value of a balanced approach. 



The array of <a href="https://www.earth.com/news/chemical-found-in-cannabis-plants-can-actually-reduce-cannabis-induced-anxiety/" target="_blank" rel="noreferrer noopener">plant chemicals</a> in items like blackberries, apples, walnuts, and spinach appears to do more than deliver vitamins or fiber. 



There’s an ongoing conversation about how these interactions may help with general health maintenance.



<h2 class="wp-block-heading" id="h-polyphenols-skin-and-healthy-aging">Polyphenols, skin and healthy aging</h2>



The possibility of smooth, glowing skin catches everyone’s attention. Polyphenols have drawn the attention of the anti-aging research community over the past decade. 



The science behind this is still emerging, but one <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC3583891/" target="_blank" rel="noreferrer noopener">study</a> suggested that these compounds may support the body’s natural defense processes in response to everyday stressors that contribute to aging.



<a href="https://www.earth.com/news/healthier-chocolate-created-by-using-the-entire-cocoa-fruit/" target="_blank" rel="noreferrer noopener">Dark chocolate</a>, green tea, and certain berries might be especially appealing in this regard. Each offers unique polyphenols that researchers are eager to examine further. 



Daily habits matter, of course, so variety in your diet helps spread out the range of phytonutrients you take in.



<h2 class="wp-block-heading" id="h-the-gut-connection">The gut connection</h2>



<a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8747136/" target="_blank" rel="noreferrer noopener">Researchers</a> often connect polyphenols with gut microbes. Plant molecules can get modified in the intestines, which may amplify or change their effects. 



Some speculate that the interplay between these molecules and our gut environment could be a big factor in everything from mental clarity to how we break down food.



Experts stress that we’re just beginning to understand how these compounds work once they’re exposed to digestive juices and gut bacteria. 



The best advice? Enjoy a diverse menu full of colorful produce, herbs, spices, nuts, and seeds.



<h2 class="wp-block-heading" id="h-sensible-approaches-to-daily-life">Sensible approaches to daily life</h2>



Again, many professionals suggest that variety is key. People who regularly reach for a mix of fruits, vegetables, whole grains, and legumes stand to reap wider benefits from the synergy of different nutrients. Relying on any one food is not recommended.



Lifestyle factors like moderate exercise, stress management, and avoiding excessive processed fare remain fundamental. It’s no secret that good health often hinges on consistent, balanced efforts rather than any one miracle source.&nbsp;



<h2 class="wp-block-heading" id="h-foods-that-contain-polyphenols">Foods that contain polyphenols</h2>



Deeply hued fruits like blackberries, blueberries, and plums are believed to hold an array of plant compounds. 



Dark <a href="https://www.earth.com/news/keeping-leafy-green-vegetables-safe-until-ready-to-eat/">green vegetables</a> and legumes bring color and variety to the plate. Spices such as cloves, cinnamon, and oregano are often praised for their robust polyphenol content. Dark chocolate and coffee remain popular picks, but they should be enjoyed in moderation.



Anyone concerned about medical conditions should consult a qualified practitioner before adjusting their diet. If you get the green light, sprinkling extra herbs on your soup or adding a handful of bright vegetables to your lunch bowl may be a simple start.



<h2 class="wp-block-heading" id="h-polyphenols-and-human-health">Polyphenols and human health</h2>



Polyphenols offer a fresh perspective on why color, aroma, and taste in nature’s foods might matter more than we ever realized. 



From green tea to bright spices, there is a growing curiosity about how these substances could contribute to long-term well-being. 



A plate that’s bursting with color might not just be pleasing to the eye - it might be quietly working to support overall health, one forkful at a time.

How polyphenols promote heart health, youthful skin and a healthy waistline

Polyphenols are natural compounds found abundantly in fruits, vegetables, tea,...

Scientists have unearthed a remarkable ancient forest preserved under ice on the Beartooth Plateau, providing a rare look into how warming climates could reshape alpine ecosystems. 



The study, published in the Proceedings of the National Academy of Sciences (<a href="https://dx.doi.org/10.1073/pnas.2412162121" target="_blank" rel="noreferrer noopener">PNAS</a>), analyzes the remnants of a mature whitebark pine forest that once thrived at an elevation of 10,000 feet during a period of warmer temperatures roughly 6,000 years ago.



<h2 class="wp-block-heading" id="h-ancient-forest-exposed-by-melting-ice">Ancient forest exposed by melting ice</h2>



The forest, which endured for centuries before cooling temperatures forced it to retreat downslope, was sealed under ice approximately 5,500 years ago due to a shift in summer solar radiation and subsequent <a href="https://www.earth.com/news/volcanic-cooling-not-warming-caused-a-major-mass-extinction/" target="_blank" rel="noreferrer noopener">volcanic cooling</a>.&nbsp;



“This is pretty dramatic evidence of ecosystem change due to temperature warming. It's an amazing story of how dynamic these systems are,” said David McWethy, one of the study’s authors and an associate professor in Michigan State University (<a href="https://www.montana.edu/" target="_blank" rel="noreferrer noopener">MSU</a>’s) Department of Earth Sciences.



Unlike glaciers, ice patches do not flow and instead preserve deposited materials such as pollen, charcoal, and macrofossils in their frozen layers. 



These conditions allowed the forest to remain intact until recent warming caused the ice to melt, exposing the ancient remnants.



<h2 class="wp-block-heading" id="h-decoding-climate-history">Decoding climate history</h2>



The idea to explore the Beartooth Plateau for ancient climate clues stemmed from earlier discoveries by Craig Lee, now an assistant professor at MSU. 



In 2007, Lee uncovered a 10,300-year-old atlatl fragment in the region, suggesting that layers of ice held vast records of cultural and environmental history.



“Most of our best long-term climate records come from Greenland and Antarctica. It's not a small thing to find ice patches that persisted for that long a time period at lower latitudes in the interior continent,” McWethy noted.

Building on this discovery, McWethy, Lee, and Greg Pederson, a paleoclimatologist with the <a href="https://www.usgs.gov/" target="_blank" rel="noreferrer noopener">U.S. Geological Survey</a>, began investigating the ice patches in 2016. By 2018, their team expanded the project to study additional alpine ice patches in the region.&nbsp;



This collaborative effort involved tribes, federal agencies, and multiple universities and focused on reconstructing the area’s long-term <a href="https://www.earth.com/news/how-earths-temperature-has-changed-over-500-million-years/" target="_blank" rel="noreferrer noopener">climate history</a> and its influence on Indigenous peoples.



<h2 class="wp-block-heading" id="h-reconstructing-the-ancient-alpine-ecosystem">Reconstructing the ancient alpine ecosystem</h2>



To piece together the story of the forest, the team examined multiple elements of this alpine <a href="https://www.earth.com/news/alpine-ecosystems-are-thrown-off-balance-by-climate-change/" target="_blank" rel="noreferrer noopener">ecosystem</a>. Using ice cores, they analyzed water isotopes and organic material, while Pederson harvested cross-sections of ancient wood for radiocarbon dating.&nbsp;



The findings confirmed that during a period of moderate and moist climate, tree lines shifted upward, allowing whitebark pine forests to thrive for 500 years.



“The plateau seems to have been the perfect place to allow for ice patches to establish and persist for thousands of years, recording important information on past climate, human activity and environmental change,” Pederson said.



The study suggests that as today’s climate warms, tree lines could rise again, transforming areas of alpine tundra into forest. 



However, Pederson cautioned that factors such as precipitation, wind, and snowpack would influence the density, distribution, and composition of these potential new forests. 



“Growing season temperatures are the primary control on tree line elevation and latitude, but other factors such as moisture, wind, <a href="https://www.earth.com/news/human-driven-climate-change-is-to-blame-for-sharp-snowpack-declines-since-1980/" target="_blank" rel="noreferrer noopener">snowpack</a> and human disturbance may play an important role in dictating forest structure and elevational limits,” he explained.



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



The researchers warn that these changes could have profound impacts on the region’s ecosystem and resources. 



Rising tree lines might alter high-altitude snowpack, which serves as a critical water source for irrigation and hydroelectric power. 



Additionally, if forests encroach on tundra areas, they could increase the risk of wildfires due to changing fuel conditions.



Cathy Whitlock, a climate expert and MSU Regents Professor Emerita, emphasized the broader implications. 



She noted that reduced snowpack could strain water supplies, while McWethy added that the establishment of forests in tundra areas might fundamentally alter the region’s fire dynamics.



<h2 class="wp-block-heading" id="h-learning-from-the-past-to-predict-the-future">Learning from the past to predict the future</h2>



The study emphasizes the importance of understanding past ecological changes to prepare for future challenges.&nbsp;



“That’s the reason why studies of past ecological change are more than interesting pieces of science. They have much larger implications for the resources we all depend on,” Pederson said.



As climate change accelerates, the Beartooth Plateau’s <a href="https://www.earth.com/news/worlds-oldest-forest-discovered-close-to-new-york-city/" target="_blank" rel="noreferrer noopener">ancient forest</a> serves as both a stark reminder of the Earth’s dynamic ecosystems and a window into the potential future of high-altitude environments.

Fossilized frozen forest discovery in the US reveals ancient alpine ecosystem

Scientists have unearthed a remarkable ancient forest preserved under ice...

It is now common knowledge that drinking tea offers many health benefits. Now, research has shown that the daily habit of drinking tea could also be delaying your biological aging.



Scientists embarked on an in-depth exploration of how our beloved brew might contribute to a longer, healthier life. 



The concept that tea, something as familiar and everyday, could hold such <a href="https://www.earth.com/news/drinking-plenty-of-tea-reduces-the-risk-of-type-2-diabetes/" target="_blank" rel="noreferrer noopener">profound health benefits</a> is truly fascinating.



<h2 class="wp-block-heading" id="h-impact-of-drinking-tea-on-human-aging">Impact of drinking tea on human aging</h2>



The research team behind this study is based at <a href="https://en.scu.edu.cn/" target="_blank" rel="noreferrer noopener">Sichuan University</a> in Chengdu, China. They mined data from a sizable sample of 5,998 British participants aged between 37 to 73, and 7,931 Chinese individuals aged 30 to 79. 



Participants opened up about their tea-drinking habits, shedding light on the type of tea they savored -- whether green, black, yellow, or oolong, and their daily consumption levels.



Published in The Lancet Regional Health journal, the study’s findings are eye-opening. Regular tea drinkers appear to flaunt signs of slower biological aging. 



The magic number seems to be around three cups or six to eight grams of <a href="https://www.earth.com/news/good-microbes-in-tea-roots-grow-tastier-healthier-plants/" target="_blank" rel="noreferrer noopener">tea leaves</a> each day, offering the most clear cut <a href="https://www.earth.com/news/lifes-essential-8-may-slow-biological-aging-by-six-years/" target="_blank" rel="noreferrer noopener">anti-aging benefits</a>.



However, there’s a catch. If you have stopped drinking tea, your biological aging might be accelerating faster. It seems that keeping up with your tea drinking habit regularly is the key to harness its benefits.



<h2 class="wp-block-heading" id="h-secret-behind-the-brew">Secret behind the brew</h2>



So, what makes tea such a secret weapon against aging? The scientists believe it's the <a href="https://www.earth.com/news/sea-buckthorn-berries-have-untapped-potential-as-a-superfood/" target="_blank" rel="noreferrer noopener">polyphenols</a> -- the primary bioactive substances in tea. 



These play a crucial role in influencing the gut microbiota, affecting age-related changes related to immunity, metabolism, and even <a href="https://www.earth.com/news/matcha-tea-relieves-symptoms-of-depression/" target="_blank" rel="noreferrer noopener">cognitive function</a>.



Regardless of whether it was a cup of UK black tea or Chinese green tea, the study didn’t find any significant differences in the anti-aging effects. 



The temperature at which the tea was consumed also didn’t impact the outcomes.



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



Beyond making your meals tastier, polyphenols are packed with antioxidants, which help protect your cells from damage caused by free radicals. Think of free radicals as tiny troublemakers that can contribute to aging and various diseases. 



By neutralizing these bad actors, polyphenols play a key role in keeping your body healthy and functioning smoothly. Incorporating polyphenol-rich foods into your diet is a simple way to boost your overall health. 



Studies suggest that these compounds can reduce inflammation, improve heart health, and even lower the risk of certain cancers. Plus, there is evidence that they enhance brain function and help keep your memory sharp as you age. 



<h2 class="wp-block-heading" id="h-the-world-of-tea-and-aging">The world of tea and aging</h2>



Tea isn't a one-size-fits-all beverage. There are different types, each offering unique health benefits through their individual processing methods.



<h3 class="wp-block-heading" id="h-green-tea-the-antioxidant-powerhouse">Green tea: The antioxidant powerhouse</h3>



<a href="https://www.earth.com/news/green-tea-and-coffee-lower-the-risk-of-fatal-cardiovascular-events/" target="_blank" rel="noreferrer noopener">Green tea</a> is known for its high antioxidant content and polyphenols. Regular consumption has been linked to improved heart health, weight loss assistance, and reduced risk of chronic diseases such as diabetes.



<h3 class="wp-block-heading" id="h-black-tea-the-robust-heart-health-enhancer">Black tea: The robust heart-health enhancer</h3>



<a href="https://www.earth.com/news/drinking-black-tea-lowers-mortality-risk-from-all-causes/" target="_blank" rel="noreferrer noopener">Black tea</a> is not only flavorful but also packed with flavonoids that enhance heart health. It’s linked to lowering stroke risk, decreasing blood pressure, and reducing LDL cholesterol levels.



<h3 class="wp-block-heading" id="h-white-tea-the-gentle-guardian">White tea: The gentle guardian</h3>



White tea, derived from the young leaves and buds of the Camellia sinensis plant, is praised for its antioxidant properties. It's known for enhancing skin health, supporting weight loss efforts, and containing less caffeine.



<h3 class="wp-block-heading" id="h-oolong-tea-the-metabolism-booster">Oolong tea: The metabolism booster</h3>



<a href="https://www.earth.com/news/oolong-tea-burns-fat-while-you-sleep/" target="_blank" rel="noreferrer noopener">Oolong tea</a> sits in between green and black tea in terms of oxidation. Celebrated for its diverse flavors, it’s also recognized for boosting metabolism and weight management.



<h2 class="wp-block-heading" id="h-how-tea-slows-aging">How tea slows aging</h2>



Further to the potential slowing of aging, tea is also linked with enhanced mental alertness, thanks to its caffeine content. 



Tea's unique blend of caffeine and the amino acid L-theanine prompts enhanced attention, better memory, and faster reaction times, leading to improved mental performance.



Notably, tea, particularly green tea, also supports dental health. Filled with fluoride, it strengthens tooth enamel and reduces the risk of tooth decay. 



The polyphenols and catechins found in tea also combat bacteria responsible for cavities and gum disease.



<h2 class="wp-block-heading" id="h-proceed-with-a-pinch-of-caution">Proceed with a pinch of caution</h2>



While the study provides promising insights, its limitations can’t be ignored. 



The size of the tea cups was not accounted for, and the findings, being observational, can't definitively conclude that tea drinking directly slows biological aging.



The UK, known for its firm tea-drinking tradition, has witnessed a decline in its younger population's demand for tea. 



But perhaps, understanding these potential health benefits may reignite the interest in the humble cup.



<h2 class="wp-block-heading" id="h-should-you-join-the-tea-club">Should you join the tea club?</h2>



If you’re a tea lover, this research validates your indulgence. If you’re not, it might be time to consider embracing this simple pleasure for the potential significant <a href="https://www.earth.com/news/true-biological-age-hidden-blood-markers-newly-identified/" target="_blank" rel="noreferrer noopener">benefits to your health</a>. 



The key appears to be moderation, with around three cups of tea a day offering the most evident anti-aging benefits.



Whether green, black, white, or oolong is your cup of tea, each brew offers an enjoyable way to potentially support your well-being. 



So, as you settle down with your next cup of tea, take a moment to savor not only the taste but also the potential health benefits that might be steeping within.

Drinking tea every day is proven to delay biological aging in humans

It is now common knowledge that drinking tea offers many...

In a significant breakthrough, researchers at the University of Wisconsin-Madison have discovered where an essential photoreceptor, cryptochrome-1 (CRY1), operates within plant seedling stems.



This finding could have profound implications for improving crop resilience and yield, especially for vital crops like soybeans.



The discovery sheds new light on how plant seedlings interact with their environment, detect sunlight, and decide their growth strategies. 



For farmers and researchers alike, understanding these processes during the vulnerable early stages of a plant's life could be key to promoting stronger, healthier crops.



<h2 class="wp-block-heading" id="h-how-photoreceptors-influence-plant-seedlings">How photoreceptors influence plant seedlings</h2>



Photoreceptors are proteins that <a href="https://www.earth.com/news/world-soil-day-2024-protecting-our-planets-lifeline/" target="_blank" rel="noreferrer noopener">plants</a> use to sense light and make growth-related decisions. They play a pivotal role in determining when a seedling should stop elongating, begin photosynthesis, and channel energy into survival and development. 



Until now, scientists understood these broad functions but lacked clarity about where in the seedling the photoreceptors acted.



“For the first time, we realized that the effect of these photoreceptors is not everywhere along the stem and that different photoreceptors control different regions of the stem,” explained Edgar Spalding, professor emeritus of botany at <a href="https://www.wisc.edu" target="_blank" rel="noreferrer noopener">UW–Madison</a>.



To unravel this mystery, Spalding, doctoral student Julian Bustamante, and data scientist Nathan Miller used a combination of techniques including genetic manipulation, high-resolution imaging, and machine learning.



The team photographed the growth of tiny seedlings with highly sensitive cameras and analyzed the data using UW–Madison’s advanced computing resources. This approach allowed them to pinpoint how specific photoreceptors influence distinct parts of the plant stem.



<h2 class="wp-block-heading" id="h-light-detection-and-plant-survival">Light detection and plant survival</h2>



One of the most fascinating discoveries from this research is the critical role of the photoreceptor CRY1 in helping seedlings survive environmental challenges.



When a seedling first emerges from the soil, it uses stored energy to elongate its stem and reach sunlight, where it can begin photosynthesis. 



However, sometimes seedlings are covered again by soil due to wind, animals, or other environmental factors. Without sunlight, they can no longer produce energy through photosynthesis.



CRY1 acts as a kind of survival mechanism. Initially, it prevents the <a href="https://www.earth.com/news/booster-plant-gene-discovery-amplifies-plant-growth-up-to-200-percent/" target="_blank" rel="noreferrer noopener">plant</a> from overextending its stem, conserving energy and leaving some growth potential in reserve. If the seedling gets buried again, CRY1 signals the plant to elongate further until it breaks through the soil and reaches sunlight once more.



This discovery is particularly significant for "stand establishment" - the phase when seedlings take root and begin to grow. Stand establishment is a critical determinant of crop success, and understanding how CRY1 functions during this period could help farmers enhance the resilience of their plants.



<h2 class="wp-block-heading" id="h-crops-of-the-future">Crops of the future</h2>



The implications of this research extend beyond academic curiosity. By genetically enhancing the role of CRY1 in seeds, researchers could develop crops better equipped to handle environmental setbacks.



This innovation could prove invaluable for farmers, particularly in regions where soil conditions or weather events make early seedling survival more challenging.



“By isolating the effects of specific photoreceptors like CRY1, we’re able to focus on ways to create <a href="https://www.earth.com/news/predicting-how-climate-change-will-alter-plant-growth-cycles/" target="_blank" rel="noreferrer noopener">plants</a> that are more adaptable to their environment,” noted Spalding.



“This research not only improves our understanding of <a href="https://www.earth.com/news/electric-soil-esoil-boosts-crop-production-by-50-in-just-15-days/" target="_blank" rel="noreferrer noopener">plant</a> biology but also opens the door to practical applications that could benefit agriculture worldwide.”



<h2 class="wp-block-heading" id="h-efficient-and-resilient-farming-methods">Efficient and resilient farming methods</h2>



As the world’s population grows, the need for more efficient and resilient farming methods becomes critical. This study on plants photoreceptors and their influence on seedling growth offers insights that could transform agriculture by enabling the creation of <a href="https://www.earth.com/news/plants-have-sophisticated-strategies-to-balance-defense-and-growth/" target="_blank" rel="noreferrer noopener">crops</a> better suited to handle environmental challenges.



By enhancing photoreceptor functions, particularly CRY1, scientists could engineer seeds that help plants recover from obstacles like being buried under soil. This innovation has the potential to increase yields, reduce crop losses, and provide a stable food supply, benefiting both farmers and consumers.



The research demonstrates the power of combining advanced genetic editing, machine learning, and traditional plant biology. It showcases how understanding plant-environment interactions can help develop crops that not only survive but thrive under adverse conditions.



The findings could pave the way for a future where agriculture is more sustainable, adaptable, and capable of meeting global food demands.



The study is published in the journal <a href="https://www.cell.com/current-biology/fulltext/S0960-9822(24)01562-8" target="_blank" rel="noreferrer noopener">Current Biology</a>.

New understanding of light detection in plants may revolutionize farming

In a significant breakthrough, researchers at the University of Wisconsin-Madison...

NASA is examining ways to ensure explorers have nourishing produce, including fresh plants, on future space missions to the Moon and Mars. While sealed food packets get the job done, they can lose flavor and vitamins over time.



Cultivating leafy greens and vegetables on the space station could address this problem and give crews a happier mental state. 



Efforts to grow plants such as lettuce, peppers, radishes, and tomatoes in microgravity have been underway, revealing new insights into how spaceflight influences plant genetics, water use, and flavor.



<h2 class="wp-block-heading" id="h-plants-are-key-to-space-exploration">Plants are key to space exploration</h2>



This work is being guided by <a href="https://npp.orau.org/experiences/gioia-massa.html" target="_blank" rel="noreferrer noopener">Gioia Massa</a> from NASA. Her background involves studying plant behavior in space to help boost the <a href="https://www.earth.com/news/why-do-astronauts-meals-lose-flavor-in-space/" target="_blank" rel="noreferrer noopener">variety and taste</a> of fresh crops.&nbsp;



As NASA paves the path toward deeper space travel, her team has focused on how <a href="https://www.nasa.gov/learning-resources/for-kids-and-students/what-is-microgravity-grades-5-8" target="_blank" rel="noreferrer noopener">microgravity</a> and factors like humidity and light control affect plant shape, nutrient quality, and yield. 



By examining bacteria that live alongside the plants, they also track whether these microorganisms remain safe and beneficial for human health.



<h2 class="wp-block-heading" id="h-growing-crops-in-microgravity">Growing crops in microgravity</h2>



One key study, <a href="https://www.nasa.gov/mission/station/research-explorer/investigation/?#id=9195" target="_blank" rel="noreferrer noopener">Plant Habitat-07</a>, looks at how lettuce tolerates different moisture conditions in microgravity. 



Although water is crucial for plant cells, too much can restrict oxygen at the roots, and too little can cause wilting.&nbsp;



This investigation uses four moisture scenarios in a specialized growth chamber to see how <a href="https://www.earth.com/news/space-tomatoes-are-ready-for-an-unprecedented-mission/" target="_blank" rel="noreferrer noopener">plants</a> adjust nutrient production. 



Researchers check yield, overall plant health, and whether bacterial populations on the leaves pose any risk. Early data point to the importance of balancing water to maintain robust leaves that still taste good.



<h2 class="wp-block-heading" id="h-making-space-grown-veggies-tastier">Making space-grown veggies tastier</h2>



NASA’s <a href="https://www.nasa.gov/mission/station/research-explorer/investigation/?#id=7896" target="_blank" rel="noreferrer noopener">Veg-04A</a> and <a href="https://www.nasa.gov/mission/station/research-explorer/investigation/?#id=7895" target="_blank" rel="noreferrer noopener">Veg-04B</a> explorations spotlighted how <a href="https://www.earth.com/news/electro-agriculture-grows-food-in-the-dark-with-94-less-land-required/" target="_blank" rel="noreferrer noopener">light quality</a> and fertilizer affect lettuce and leafy greens on station. 



Studies found that switching red and blue LEDs, or adjusting nutrient formulas, changes how the leaves look, taste, and grow.&nbsp;



These investigations guided more recent plantings of other crops, such as tomatoes. Crew members gave feedback on freshness and flavor, which could inform future seed selection for diverse salads during long-duration spaceflights.

A <a href="https://biologydirect.biomedcentral.com/articles/10.1186/s13062-024-00476-z" target="_blank" rel="noreferrer noopener">study</a> on Arabidopsis thaliana (<a href="https://www.ncbi.nlm.nih.gov/gene?cmd=DetailsSearch&amp;term=AT1G19968" target="_blank" rel="noreferrer noopener">thale cress</a>) showed that low gravity changes gene expression and how plants regulate key chemical markers. Researchers tracked DNA methylation—a process that can switch genes on or off. 



Their discoveries open new avenues for customizing plant genes to handle the difficulties of space, like unusual water movement or limited floor space.



<h2 class="wp-block-heading" id="h-hormones-and-movement">Hormones and movement</h2>



Scientists have <a href="https://www.nasa.gov/mission/station/research-explorer/investigation/?#id=1730" target="_blank" rel="noreferrer noopener">explored</a> how plant hormones guide growth in microgravity. One series of tests examined <a href="https://pubmed.ncbi.nlm.nih.gov/34396657/" target="_blank" rel="noreferrer noopener">auxins</a>, natural signals that steer root and shoot direction.&nbsp;



Some <a href="https://www.earth.com/news/grow-plants-on-moon-by-2026-nasa-artemis-iii-mission/" target="_blank" rel="noreferrer noopener">plant</a> species had lower auxin levels when floating in microgravity, which curbed their normal pattern of upward stem development. 



Others had higher levels, suggesting that the exact outcome varies by species. This subtle shift in plant chemistry helps NASA design growth chambers that best support each crop’s needs.



<h2 class="wp-block-heading" id="h-engineering-plants-to-handle-space">Engineering plants to handle space</h2>



Roots and shoots in microgravity can develop weaker supportive tissues or, in some cases, produce thicker walls for unknown reasons. 



An <a href="https://www.nature.com/articles/s41526-023-00312-0" target="_blank" rel="noreferrer noopener">investigation</a> used a suite of lab tools to identify changes in molecules that build plant cell walls, especially those providing mechanical strength.&nbsp;



Although some species quickly adapt and form healthy walls, others remain frail. NASA’s next step is to refine which varieties flourish with minimal gravity or to tweak conditions so roots are less prone to bending or thinning.



<h2 class="wp-block-heading" id="h-sterols-and-space-based-flowering">Sterols and space-based flowering</h2>



Researchers on the <a href="https://www.nasa.gov/news-release/first-contracted-spacex-resupply-mission-launches-with-nasa-cargo-to-space-station/">Resist Tubule</a> mission <a href="https://www.jstage.jst.go.jp/article/bss/38/0/38_18/_article">uncovered</a> that arabidopsis plants grown in microgravity sometimes see reduced sterol levels.&nbsp;



Sterols help keep cell membranes stable and support a range of growth responses, including when and how a plant transitions to flowering. 



The drop in sterols in microgravity can slow certain steps in development. By noting which genes control those sterols, scientists may spot ways to keep plants on schedule.



<h2 class="wp-block-heading" id="h-preparing-for-space-missions-with-plants">Preparing for space missions with plants</h2>



Having tasty salad greens aboard the station is only the first step. NASA’s focus is on sustaining crews through missions lasting many months. 



The progress so far is encouraging: fresh produce is feasible in orbit, and each new finding helps refine the process.&nbsp;



As more crops are tested for flavor, nutrition, and shelf life, humans gain the ability to grow food far from our planet. 



With input from experts like Gioia Massa, the future of in-space agriculture looks promising for both nourishment and crew satisfaction.

Space lettuce: NASA's plans to grow nutritious plants on Mars

NASA is examining ways to ensure explorers have nourishing produce,...

Pawpaws, the largest native fruit in North America, have become a favorite among foragers and food enthusiasts. 



Found in their characteristic dense patches, they are known for their creamy, custard-like texture and sweet flavor - described as a mix of mango and banana - and offer a unique culinary experience.



However, the ecological impact of pawpaws extends far beyond their popularity as a delicious treat.



<h2 class="wp-block-heading" id="h-pawpaw-patches-take-over-the-forest">Pawpaw patches take over the forest</h2>



Pawpaws, the state fruit tree of Missouri, naturally grow in groups called patches. These patches form because pawpaw trees can reproduce clonally, meaning they spread through their roots.



New stems grow from these roots, close to the original tree, in a way similar to how aspen <a href="https://www.earth.com/news/plant-diversity-darkspots-need-urgent-attention/" target="_blank" rel="noreferrer noopener">trees</a> create groves. This process allows a single pawpaw tree to establish a larger group of genetically identical trees, which is why these patches are often celebrated in American folk songs.



However, these patches don’t just grow - they take over. Pawpaw trees spread quickly, creating dense clusters that dominate the forest understory.



Their thick growth and clonal expansion leave little space or resources for other plants to thrive, effectively reducing plant diversity and altering the local ecosystem. While these patches are great for pawpaws, they can significantly limit the growth of other species around them.



<h2 class="wp-block-heading" id="h-pawpaws-effect-on-plant-diversity">Pawpaws’ effect on plant diversity</h2>



New research from <a href="https://washu.edu" target="_blank" rel="noreferrer noopener">Washington University</a> in St. Louis highlights how pawpaw patches influence biodiversity.



“Pawpaws create a habitat where the rules of competition are more random than when they’re absent,” noted Anna Wassel, a graduate student and lead author of the study.



The researchers found that pawpaw patches have a significant <a href="https://www.earth.com/news/planting-diverse-crops-traps-carbon-and-boosts-soil-health/" target="_blank" rel="noreferrer noopener">impact on plant diversity</a> within their boundaries. Specifically, the variety of herbaceous plants, which include smaller, non-woody species like grasses and wildflowers, was 49% lower inside pawpaw patches compared to areas outside.



This indicates that nearly half of the usual types of these plants struggle to survive in the environment created by pawpaw trees. The dense shade and competitive conditions within the patches make it difficult for many plant species to thrive.



<h2 class="wp-block-heading" id="h-pawpaw-patches-decrease-plant-density">Pawpaw patches decrease plant density</h2>



In addition to reduced diversity, the total density of <a href="https://www.earth.com/news/humans-have-shaped-plant-biodiversity-for-thousands-of-years/" target="_blank" rel="noreferrer noopener">plants</a> - combining both woody species like shrubs and herbaceous species - was found to be 29% lower inside pawpaw patches.



This means not only are there fewer types of plants, but also fewer individual plants overall. The dominance of pawpaw trees and their resource consumption leave less room and <a href="https://www.earth.com/news/how-plant-diversity-can-help-combat-climate-change/" target="_blank" rel="noreferrer noopener">fewer resources for other plants to grow</a>.



The study also revealed that pawpaw patches increase the randomness of which plants survive, particularly at larger scales. 



In typical forest ecosystems, plants compete for sunlight, water, and nutrients in predictable ways, with certain species better adapted to the conditions prevailing. However, inside pawpaw patches, these usual rules of competition break down. 



The survival of plants becomes more random, disrupting the natural balance of the ecosystem. This unpredictability makes it harder for a stable and diverse plant community to form within pawpaw-dominated areas.



<h2 class="wp-block-heading" id="h-why-pawpaw-patches-ruin-other-plants">Why pawpaw patches ruin other plants</h2>



Pawpaw trees have a strong ability to outcompete other plants, thanks to <a href="https://www.earth.com/news/plants-in-dry-landscapes-have-surprising-diversity/" target="_blank" rel="noreferrer noopener">several factors</a>. 



Their large, tropical-looking leaves create dense shade, blocking sunlight that many smaller plants need to grow. Without enough light, these plants struggle to survive and thrive under the pawpaw canopy.



Additionally, pawpaw trees spread through underground roots and produce multiple stems in one area. This high stem density increases competition for soil nutrients and water, leaving fewer resources for other plants in the vicinity.



Another factor is that deer tend to avoid eating pawpaw trees. Instead, they graze on other plants nearby, further reducing the variety of plant species in and around pawpaw patches. 



This combination of shading, resource competition, and selective deer browsing makes pawpaw patches a tough environment for other plants to grow - significantly lowering local biodiversity.



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



The study’s findings offer important lessons for managing forest ecosystems. 



“If you are monitoring a plot of land with the aim to encourage the growth of understory species, unfortunately, pawpaws are not your friends,” Wassel noted. 



The dominance and unpredictability of pawpaw patches make them a challenge for land managers focused on promoting <a href="https://www.earth.com/news/islands-are-home-to-one-third-of-all-known-plants/" target="_blank" rel="noreferrer noopener">plant diversity</a>.



However, for those interested in harvesting pawpaw fruit, the approach is different. To ensure cross-pollination and healthy fruit production, managers should encourage as many genetically distinct patches as possible.



“The presence of pawpaws is never inherently good or bad, it’s just natural. Nature’s goals are never as linear as ours,” noted Wassel.

Pawpaw trees form dense patches that outcompete other plants

Pawpaws, the largest native fruit in North America, have become...

A study from Chapman University provides the first comprehensive global estimates of water storage in Earth’s vegetation and the time it takes for that water to flow through plants. The research fills a critical gap in our understanding of the global water cycle and its sensitivity to climate and land-use changes.



Published in the journal Nature Water, the study reveals that Earth's vegetation holds about 786 km³ of water, a mere 0.002% of Earth’s total freshwater.



However, the significance lies in the rapid movement of water through plants. This transit time, from absorption to release into the atmosphere, is among the fastest in the water cycle - ranging from five days in croplands to 18 days in evergreen needleleaf forests.



For perspective, water in lakes takes around 17 years to cycle, and in glaciers, the process spans 1,600 years.



<h2 class="wp-block-heading" id="h-continuous-loop-of-earth-s-water-cycle">Continuous loop of Earth's water cycle</h2>



Earth's water cycle, or <a href="https://www.earth.com/earthpedia-articles/water-cycle/" target="_blank" rel="noreferrer noopener">hydrological cycle</a>, is the continuous movement of water through the environment. It begins with evaporation, where the <a href="https://www.earth.com/news/rising-temperatures-are-wreaking-havoc-on-the-global-water-cycle/" target="_blank" rel="noreferrer noopener">sun heats water</a> from oceans, lakes, and rivers, turning it into vapor.



This vapor rises into the atmosphere and cools, leading to&nbsp;condensation, which forms clouds. When the clouds become heavy, water returns to Earth as&nbsp;precipitation&nbsp;in the form of rain, snow, or hail. 



Once on the ground, water either flows over the surface into rivers and lakes (runoff) or seeps into the soil (infiltration). 



Plants also play a role by releasing water vapor into the air through&nbsp;transpiration. Together, these processes recycle water, connecting oceans, land, and the atmosphere in a continuous loop.



<h2 class="wp-block-heading" id="h-a-forgotten-element-of-the-water-cycle">A forgotten element of the water cycle</h2>



“Plants are the forgotten part of the global water cycle,” noted Dr. Andrew Felton, lead author and professor at <a href="https://www.montana.edu" target="_blank" rel="noreferrer noopener">Montana State University</a>. Despite their critical role in returning water from the ground to the atmosphere, plants are often excluded from water cycle diagrams.



“Our results show that the transit of water through plants occurs on the order of days, rather than months, years, or centuries, as it does in other parts of the water cycle,” said Dr. Felton.



By combining plant water transit estimates with those for the atmosphere (8–10 days) and soil (60–90 days), researchers can now approximate the total time a drop of water spends in the terrestrial cycle.



<h2 class="wp-block-heading" id="h-intensification-of-the-water-cycle">Intensification of the water cycle</h2>



One striking finding is the rapid transit of water through croplands. During peak growing seasons, water cycles through crops in less than a day. This speed, consistent across global croplands, hints at a broader environmental implication.



“Land use change may be homogenizing the global water cycle and contributing to its intensification by more rapidly recycling water back to the atmosphere where it can turn into heavy rain events,” explained <a href="https://www.chapman.edu/our-faculty/greg-goldsmith" target="_blank" rel="noreferrer noopener">Dr. Gregory Goldsmith</a>, senior author and associate professor at Chapman University.



<h2 class="wp-block-heading" id="h-water-dynamics-in-earth-s-vegetation">Water dynamics in Earth's vegetation</h2>



The research team utilized data from NASA’s Soil Moisture Active Passive Mission (<a href="https://smap.jpl.nasa.gov" target="_blank" rel="noreferrer noopener">SMAP</a>), a satellite program designed to measure soil moisture across Earth’s surface.



SMAP data accounted for vegetation interference, which the satellite originally treated as noise to correct soil moisture readings. However, the researchers discovered that these corrections held important information about the amount of water stored in plants.



By analyzing this overlooked data and combining it with advanced measurements of how quickly water exits plants, the team developed detailed estimates. 



These included five years of monthly data on plant water storage and the time water takes to move through vegetation, calculated with a spatial resolution of&nbsp;9 square kilometers (approximately 3.5 square miles). 



This high-resolution analysis provided a remarkable understanding of <a href="https://www.earth.com/news/distress-signals-earths-water-cycle-is-becoming-more-erratic/" target="_blank" rel="noreferrer noopener">water dynamics within Earth's vegetation</a>.



<h2 class="wp-block-heading" id="h-implications-for-a-changing-planet">Implications for a changing planet</h2>



The study highlights the sensitivity of plant water transit times to environmental events like deforestation, drought, and wildfires. 



“The results suggest that the transit time of water through plants is likely to be very sensitive to events such as deforestation, drought and wildfire, which will fundamentally change the time it takes for water to flow through the water cycle,” said Felton.



By shedding light on the dynamic role of vegetation, this research highlights the interconnectedness of ecosystems and the urgent need to understand how land-use changes influence the global water cycle.



As the planet faces intensifying climate challenges, studies like this pave the way for more informed strategies to manage water resources and <a href="https://www.earth.com/news/sci-fi-inspired-scenarios-illustrate-our-impact-on-earths-water-cycle/" target="_blank" rel="noreferrer noopener">predict environmental shifts</a>.

Water moves through plants and back into the atmosphere with unexpected speed

A study from Chapman University provides the first comprehensive global...

Every day, countless cups of coffee leave behind piles of waste and grounds that often end up in landfills. People around the globe are seeking ways to reduce this organic trash, and construction researchers have identified a method that may give old coffee grounds a second life.



By finding innovative solutions, they are turning waste into a tool for advancing sustainability across industries, addressing the issue of waste management, and offering benefits to industries beyond the <a href="https://www.earth.com/news/coffee-production-threatened-by-loss-of-pollinators/" target="_blank" rel="noreferrer noopener">coffee sector</a>.



By reimagining a common byproduct, scientists are opening doors to more sustainable and practical applications for organic waste, thereby transforming a problem into a valuable resource, which could redefine how organic waste is utilized.



<h2 class="wp-block-heading" id="h-turning-coffee-grounds-into-stronger-concrete">Turning coffee grounds into stronger concrete</h2>



RMIT University engineer <a href="https://www.rmit.edu.au/profiles/r/rajeev-roychand" target="_blank" rel="noreferrer noopener">Dr. Rajeev Roychand</a> and his colleagues have demonstrated that processing leftover coffee grounds can make concrete significantly stronger.&nbsp;



To unlock these benefits, researchers placed coffee waste in a low-oxygen environment and heated it to over 350 °F (about 660 °F). This heating method, called pyrolysis, changes the grounds into a carbon-rich material.



The treatment alters the coffee grounds at a molecular level, transforming them into a material that integrates well with concrete. More importantly, it enables the production of stronger concrete with reduced environmental impacts.



<h2 class="wp-block-heading" id="h-why-pyrolysis-is-key">Why pyrolysis is key</h2>



Pyrolysis involves heating organic matter in the absence of oxygen. When coffee waste is treated with this process at 350 °C, it transforms into a substance known as biochar, which carries the advantage of being able to bond effectively with cement.



In general, the construction industry has long faced challenges with resource consumption, particularly related to sand extraction. 



Using biochar derived from coffee can replace a portion of the sand that goes into concrete, thus lowering demand for natural sand.



This process not only lessens dependency on finite resources but also aligns with the growing push for sustainable construction practices. 



The pyrolyzed <a href="https://www.earth.com/news/coffee-flavor-can-be-improved-with-a-simple-trick/" target="_blank" rel="noreferrer noopener">coffee</a> biochar creates a porous structure that improves the way concrete holds together under stress. 



This method provides a dual benefit: finding a productive use for waste while simultaneously addressing the ecological impacts of sand extraction.



<h2 class="wp-block-heading" id="h-reducing-organic-waste-and-emissions">Reducing organic waste and emissions</h2>



Experts <a href="https://ico.org/resources/trade-statistics-tables/" target="_blank" rel="noreferrer noopener">estimate</a> that global coffee consumption generates around 10 billion kilograms (22 billion pounds) of spent grounds each year. Much of this waste takes up precious space in landfills, while also releasing methane and carbon dioxide.&nbsp;



Methane is considered to be a more harmful greenhouse gas than carbon dioxide over a 100-year period. Hence, diverting this waste toward sustainable uses could significantly reduce greenhouse gas emissions. 



Ultimately, with coffee consumption so widespread, even small changes in recycling practices could have far-reaching effects on the environment.



“The disposal of organic waste poses an environmental challenge as it emits large amounts of greenhouse gases,” said <a href="https://www.sciencedirect.com/science/article/pii/S0959652623023636" target="_blank" rel="noreferrer noopener">Roychand</a>. By recycling coffee grounds, researchers hope to mitigate these environmental impacts while improving concrete’s quality.



<h2 class="wp-block-heading" id="h-indigenous-perspective-on-sustainability">Indigenous perspective on sustainability</h2>



“Inspiration for my research, from an Indigenous perspective, involves Caring for Country,” said RMIT engineer and co-researcher <a href="https://www.rmit.edu.au/news/all-news/2022/august/indigenous-researcher-ppe-innovation" target="_blank" rel="noreferrer noopener">Dr. Shannon Kilmartin-Lynch</a>.



Sustainable practices that keep organic waste from landfills can protect ecosystems, minimize pollution, and preserve natural resources. 



This philosophy integrates cultural respect for the environment with cutting-edge engineering techniques. Using coffee biochar in construction aligns with this idea of managing resources more responsibly.



<h2 class="wp-block-heading" id="h-will-this-really-work">Will this really work?</h2>



The coffee-biochar blend requires further testing to confirm its performance over extended periods. Scientists want to know how it stands up to water exposure, freeze-and-thaw cycles, and constant use.



These durability tests will help determine whether biochar-infused <a href="https://www.earth.com/news/recycled-cement-is-an-absolute-miracle-to-lower-concrete-emissions/" target="_blank" rel="noreferrer noopener">concrete</a> can meet the rigorous demands of modern infrastructure projects.



They are also planning to work with different types of organic waste (like wood scraps, food leftovers, and agricultural byproducts) to see if these can also be converted into materials that improve concrete’s structural properties.



These assessments are critical for determining whether the material can be used in large-scale construction projects. 



The research team is committed to exploring the practicality of biochar-based concrete under real-world conditions to ensure its reliability and safety.



<h2 class="wp-block-heading" id="h-future-of-coffee-grounds-and-concrete">Future of coffee grounds and concrete</h2>



As buildings rise and infrastructure expands, the search for more sustainable practices will become even more urgent. This approach of adding coffee biochar to concrete could contribute to the circular economy.



Transforming a problematic waste into a valuable input, is the first push of many required to reduce reliance on raw materials such as natural sand. 



The example of this approach sets the stage for industries to adopt similar methods, encouraging broader adoption of waste-to-resource strategies.



Such actions promise to lessen the environmental strain while boosting the long-term resilience of <a href="https://www.earth.com/news/how-ancient-romans-made-such-incredibly-durable-concrete-is-no-longer-a-mystery/" target="_blank" rel="noreferrer noopener">construction methods</a>.



Through continued collaboration between scientists, policymakers, and businesses, innovations like this have the potential to reshape the way we think about resources. 



By connecting waste management to infrastructure, this research could redefine sustainability in the modern era.



The research findings were published in the <a href="https://www.sciencedirect.com/science/article/pii/S0959652623023636" target="_blank" rel="noreferrer noopener">Journal of Cleaner Production</a>.
