It is endemic to Florida, where it is known from four or five occurrences in Hernando and Hillsborough Counties. Its population has fluctuated throughout the years; at one point in the early 1980s it was feared extinct. Today there are two populations in Hernando County and probably three in Hillsborough River State Park. At the time the plant was listed as an endangered species of the United States in 1989, it was known from three small populations on wet prairies that were threatened by changes in the local hydrology and by pollution. It was also thought to be threatened by vandalism, trampling, and collecting by flower enthusiasts. Cattle grazing and invasion of the habitat by the exotic skunkvine also degrade the habitat.

Researchers in China have been looking into several species of medicinal fungi to find new ways to address problems of the central nervous system, where conditions like Alzheimer’s and Parkinson’s diseases affect millions of people worldwide.



<a href="https://www.researchgate.net/profile/Xiaoqian-Liu-9" target="_blank" rel="noreferrer noopener">Dr. Yang Liu</a>, from a Shandong-based research group, emphasizes that these mushrooms have long been used in Chinese medicine. 



The team’s recent findings suggest that bioactive ingredients found in several fungi may support brain function without causing burdensome side effects.



<h2 class="wp-block-heading" id="h-understanding-bioactive-components">Understanding bioactive components</h2>



Some of these fungi contain <a href="https://www.sciencedirect.com/topics/biochemistry-genetics-and-molecular-biology/polysaccharide" target="_blank" rel="noreferrer noopener">polysaccharides</a>, <a href="https://www.sciencedirect.com/topics/pharmacology-toxicology-and-pharmaceutical-science/triterpenoid" target="_blank" rel="noreferrer noopener">triterpenoids</a>, and other active compounds. These components have caught attention for their potential to aid normal nerve functioning in older adults. They may also help ease oxidative damage in brain tissue by scavenging free radicals.



Many <a href="https://www.earth.com/news/fungal-diseases-that-infect-humans-are-becoming-more-common-in-warming-world/" target="_blank" rel="noreferrer noopener">fungal extracts</a> appear to reduce harmful inflammation. That matters because chronic inflammatory reactions in the brain can lead to diminished thinking skills and worsen certain diseases of the nervous system. 



By restraining the overproduction of pro-inflammatory substances, fungi may help maintain a steadier internal environment for nerve cells.



<h2 class="wp-block-heading" id="h-how-aging-populations-raise-the-stakes">How aging populations raise the stakes</h2>



As people live longer, the number of those affected by diseases of the nervous system is expected to rise sharply. 



Age is one of the biggest risk factors for conditions like <a href="https://www.earth.com/news/17-year-old-man-breaks-the-world-record-for-early-onset-alzheimers-disease/" target="_blank" rel="noreferrer noopener">Alzheimer's</a> and <a href="https://www.earth.com/news/pesticide-exposure-increases-the-risk-of-parkinsons-disease/" target="_blank" rel="noreferrer noopener">Parkinson’s</a>, which makes prevention and early support more important than ever.



This current trend is pushing scientists to find solutions that don’t rely solely on synthetic drugs. 



Many older adults prefer natural options with fewer side effects, and medicinal mushrooms could offer one such path if their benefits continue to be confirmed through research.



<h2 class="wp-block-heading" id="h-why-these-fungi-stand-out">Why these fungi stand out</h2>



Modern pharmaceuticals for diseases of the nervous system often work on specific symptoms. 



Yet they don’t always slow the actual progression of conditions like Alzheimer’s. <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5987239/" target="_blank" rel="noreferrer noopener">Scientists</a> suspect some mushrooms could do more than manage symptoms.



Early findings hint at better antioxidant protection and improved cellular cleanup processes, which are vital for the brain’s long-term health.



Many <a href="https://pubmed.ncbi.nlm.nih.gov/31460832/" target="_blank" rel="noreferrer noopener">studies</a> also note that certain fungi support a balanced <a href="https://www.earth.com/news/gut-bacteria-influence-our-social-behavior-and-sense-of-fairness/" target="_blank" rel="noreferrer noopener">intestinal microbiome</a>. The microbiome influences health beyond digestion by affecting how the body regulates mood, memory, and inflammatory signals. 



A healthy gut environment often aligns with greater mental sharpness, which is why the microbiome has turned into a hotspot for brain-related research.



<h2 class="wp-block-heading" id="h-research-shaping-potential-therapies">Research shaping potential therapies</h2>



The extracts of species such as <a href="https://www.ncbi.nlm.nih.gov/books/NBK92757/" target="_blank" rel="noreferrer noopener">Ganoderma lucidum</a> have drawn a lot of interest for their neuroprotective properties. They appear to regulate immune cell activity in ways that safeguard fragile neurons. 



Meanwhile, compounds from <a href="https://www.sciencedirect.com/science/article/pii/S2667142523000143" target="_blank" rel="noreferrer noopener">Cordyceps militaris</a> seem promising in stroke and Parkinson’s models, possibly due to their ability to moderate excessive inflammation.



Tests in laboratory models indicate these mushrooms can be gentle on the body. When used with standard treatments, they might help patients manage symptoms while protecting nerve cells against oxidative harm. 



Efforts are now underway to transform these natural agents into standardized preparations that could be easier for people to incorporate into daily regimens.



<h2 class="wp-block-heading" id="h-turning-lab-results-into-real-solutions">Turning lab results into real solutions</h2>



Clinical researchers are still exploring which precise compounds in <a href="https://www.earth.com/news/new-species-of-glowing-mushrooms-discovered-mycena-crocata/">mushrooms</a> can cross the blood-brain barrier. That information matters for designing targeted therapies. 



To get there, advanced tools like mass spectrometry and molecular modeling are helping identify the relevant components. After verifying safety and purity, scientists will need to track long-term outcomes in humans.



Pharmaceutical and food industries are keen to develop mushroom-based products that are convenient to consume. Capsules, powders, and functional beverages could all become options in the future. 



Although these ideas are still in development, initial patents and prototypes have started to appear, reflecting the potential for more widespread use.



<h2 class="wp-block-heading" id="h-exploring-safety-and-public-trust">Exploring safety and public trust</h2>



Before mushroom-based therapies can gain traction, people want to know they’re safe. Although many of these <a href="https://www.earth.com/news/hundreds-of-fungi-species-are-threatened-with-extinction/">fungi</a> have been consumed for centuries in traditional medicine, formal clinical testing is needed to confirm their safety in concentrated forms.



Researchers are calling for long-term toxicity studies and more trials in diverse human populations. 



This would help build public trust and ease the concerns of doctors and health regulators who are cautious about introducing natural compounds without thorough vetting.



<h2 class="wp-block-heading" id="h-challenges-and-hopes">Challenges and hopes</h2>



Some people worry about taking unregulated supplements, and that is where standards come in. Researchers and <a href="https://www.earth.com/news/your-twenties-can-make-or-break-your-heart-health/">health</a> agencies alike stress the importance of careful quality checks, especially as more individuals look to nontraditional therapies. 



By setting guidelines for dosage and composition, consumers could gain safer access to these mushrooms’ useful attributes. Coordinated efforts will likely speed progress in this field. 



Specialists from multiple disciplines are combining laboratory data with patient observations to make sure any mushroom-based approach is both reliable and backed by evidence. 



This blend of natural wisdom and modern science might yield new ways to manage conditions that have stumped clinicians for years.



The study is published in the <a href="https://ift.onlinelibrary.wiley.com/doi/10.1111/1750-3841.70230" target="_blank" rel="noreferrer noopener">Journal of Food Science</a>.

Chinese scientists identify medicinal fungi with potential to slow down nervous system diseases

Researchers in China have been looking into several species of...

Seagrasses grow in shallow ocean waters and rarely grab headlines. Most people notice them only when their leaves wash up on the beach. Yet, those unassuming underwater plants, have a big role in the way our planet stores carbon.



Researchers have found that these coastal meadows <a href="https://www.earth.com/news/natural-climate-solutions-enhancing-the-role-of-seagrass-meadows/" target="_blank" rel="noreferrer noopener">trap</a> significant amounts of organic matter beneath their thin blades. They act like natural buffers against the rising levels of carbon dioxide in the air.



After several years of data gathering, they have drawn attention from experts worldwide, including the lead author, Dr. Johannes R. Krause from the <a href="https://www.fiu.edu/" target="_blank" rel="noreferrer noopener">Florida International University</a>.



<h2 class="wp-block-heading" id="h-why-seagrass-matters-for-carbon-storage">Why seagrass matters for carbon storage</h2>



<a href="https://www.earth.com/news/seagrass-meadows-under-threat-herbivores-migrating-warm-waters/" target="_blank" rel="noreferrer noopener">Seagrasses</a> thrive close to shore, so they often face pollution, excessive nutrient runoff, and increased sediment in the water. Despite these challenges, they continue to draw in carbon and store it in their roots and the soil around them.



They also provide key habitats for fish and help shelter coastlines from erosion. Many ocean species depend on these meadows for breeding and feeding, which makes conservation efforts critical for biodiversity.



Seagrasses typically occupy only a small portion of the sea floor but hold a noteworthy share of carbon in their soils and biomass. One <a href="https://www.nature.com/articles/ngeo1477" target="_blank" rel="noreferrer noopener">analysis</a> showed that these plants are a major factor in global carbon burial, potentially storing more organic carbon than some forests on land.



Their presence under the waves keeps a portion of what would otherwise be released into the air locked away. It is a natural function that scientists are eager to protect in a warming world.



<h2 class="wp-block-heading" id="h-how-seagrass-stores-and-traps-carbon">How seagrass stores and traps carbon</h2>



“We now have comprehensive data to form a more complete and nuanced understanding of seagrass blue carbon,” said Dr. Krause. 



The assessment found that the top 12 inches of seagrass soil hold a median estimate of around 24.2 metric tons of <a href="https://www.nrcs.usda.gov/sites/default/files/2022-10/total_organic_carbon.pdf" target="_blank" rel="noreferrer noopener">organic carbon</a> for every 2.47 acres.&nbsp;Researchers once believed these plants formed large storage banks only in certain regions or species. 



Data now show that even small or short-lived species can hide sizable amounts below the surface in some locations. That means protective measures cannot ignore areas with less dense or shorter <a href="https://www.earth.com/news/seagrass-meadows-and-climate-change-an-uncertain-future/" target="_blank" rel="noreferrer noopener">grasses</a>.



The authors of the study highlight that persistent plants with robust below-ground systems often accumulate more buried carbon. However, fast-growing species in places with plenty of sediment can also collect notable soil carbon if conditions allow it to remain undisturbed.



<h2 class="wp-block-heading" id="h-why-this-matters-for-climate-policy">Why this matters for climate policy</h2>



Seagrass regions have faced declines worldwide. Coastal development, water pollution, and activities like <a href="https://www.msc.org/what-we-are-doing/our-approach/fishing-methods-and-gear-types/demersal-or-bottom-trawls" target="_blank" rel="noreferrer noopener">bottom trawling</a> disturb these meadows, which may trigger the release of <a href="https://www.researchgate.net/publication/355854254_Anthropogenic_pressures_and_life_history_predict_trajectories_of_seagrass_meadow_extent_at_a_global_scale" target="_blank" rel="noreferrer noopener">carbon</a> stored for centuries into the atmosphere.



When plants die off, their buried layers become exposed to waves and currents. This stirs up and oxidizes their trapped organic matter, leading to a spike in carbon dioxide flow out of the ocean. That jump could challenge efforts to slow greenhouse gas buildup.



If large-scale losses of these habitats continue, it could come with a substantial economic cost. By some estimates, the future release of carbon could run into the billions of dollars when the social cost of emissions is calculated.



Seagrass meadows store carbon while also supporting local economies and cultures reliant on healthy fisheries. Protecting these coastal habitats can reduce climate risks and sustain jobs and food sources.



<h2 class="wp-block-heading" id="h-restoring-seagrass-habitats">Restoring seagrass habitats</h2>



Scientists agree that reliable mapping of seagrass <a href="https://www.earth.com/news/study-reveals-the-evolutionary-adaptations-of-seagrasses/" target="_blank" rel="noreferrer noopener">distribution</a> is vital. At times, meadows remain undiscovered in remote areas, and many species are only sparsely documented. A clearer picture could inform local managers seeking to protect vulnerable spots.



Restoration projects, where feasible, can help rebuild seagrass coverage in places where it has dwindled. Such work involves replanting healthy shoots and ensuring water conditions encourage stable growth. Patience is key, since soil carbon accumulates gradually.



Preserving these sites yields more than just carbon benefits. They also help stabilize shorelines and bolster local marine life populations. This combined payoff makes the case for addressing pollution, regulating damaging fishing methods, and encouraging ecotourism or other sustainable coastal activities.



Securing seagrass meadows can be a direct move toward meeting international climate targets. By curbing losses and letting soils remain intact, communities retain a nature-based ally in carbon management while protecting ocean resources for future generations.



<h2 class="wp-block-heading" id="h-preserving-seagrass-for-carbon-storage">Preserving seagrass for carbon storage</h2>



Every patch of seagrass harbors potential value, both as a haven for marine life and as a natural reservoir of organic carbon. Researchers stress that the top layer of soil is especially prone to being stirred up by human impacts, so it warrants close attention.



Decisions made now can either help these unassuming plant meadows remain a subtle carbon safeguard or push them to release what they have stored. Public awareness and supportive policies will shape how we handle these critical coastal zones moving forward.

Seagrass plays a major role in global carbon storage

Seagrasses grow in shallow ocean waters and rarely grab headlines....

One chilly day, a family in Sri Lanka came upon a bright red mushroom emerging from the wet earth in their home garden. It carried a strange shape and a bulbous base, so they snapped a quick photo and began asking around.



They soon connected with <a href="https://www.researchgate.net/profile/Bhathiya-Gopallawa" target="_blank" rel="noreferrer noopener">Bhathiya Gopallawa</a>, a doctoral researcher from the University of Peradeniya, who recognized something unusual in that image. 



When he and his colleagues checked historic records, they identified it as <a href="https://www.mushroomexpert.com/mutinus_bambusinus.html" target="_blank" rel="noreferrer noopener">Mutinus bambusinus</a>, a fungus recorded just once, in 1919, and then never reported again.



<h2 class="wp-block-heading" id="h-stinkhorn-mushrooms-reappearance">Stinkhorn mushrooms reappearance</h2>



This fungus has a vivid red look that can catch anyone off guard. It is known for producing a strong odor in its spore mass, which attracts insects.



Scientists believe insects help carry away the spores, which can spread the fungus to other areas. The recent finding hints that this mushroom could be more widespread than once assumed.



Many <a href="https://hort.extension.wisc.edu/articles/stinkhorns/" target="_blank" rel="noreferrer noopener">stinkhorn</a> mushrooms rely on insects rather than wind for spore movement. Mutinus bambusinus emits a slimy layer that smells unpleasant to humans.



Flies are especially drawn to foul scents, so they flock to these mushrooms. Once they land, they accumulate spores on their legs and then carry them to other locations without even knowing it.



<h2 class="wp-block-heading" id="h-surprising-lack-of-bamboo">Surprising lack of bamboo</h2>



A century ago, the fungus was first noted in bamboo debris. This time, it sprouted in a spot with no bamboo in sight.



This unexpected setting has sparked questions about its ecological needs. Perhaps it can exist in a broad range of habitats but was overlooked for generations.



“We expect more reports in the coming months,” said Gopallawa.The image sent by the family opened the door for more mushroom sightings.&nbsp;



Such local discoveries help experts keep track of rare species. Home gardeners are often the first to notice unfamiliar organisms in yards or flowerbeds.



<h2 class="wp-block-heading" id="h-why-stinkhorn-mushrooms-matter">Why stinkhorn mushrooms matter</h2>



Experts say it is encouraging to find species thought missing. Some plants, fungi, and animals can pop up again, as highlighted by the <a href="https://www.weforum.org/stories/2024/06/rediscovered-species-biodiversity/" target="_blank" rel="noreferrer noopener">World Economic Forum</a>.



Yet it does not erase the reality that many living things are truly extinct. Conservation remains essential for all, despite these happy surprises.



Biodiversity is known to help stabilize ecosystems, per the <a href="https://www.un.org/en/climatechange/science/climate-issues/biodiversity" target="_blank" rel="noreferrer noopener">United Nations</a>. When we lose it, we threaten our food supply and water quality.



Each species plays a part in balancing the web of life. A single organism can be a valuable puzzle piece in a fragile and interconnected system.



<h2 class="wp-block-heading" id="h-global-importance-of-fungi">Global importance of fungi</h2>



“This is a great example of how citizen science can contribute to formal research,” said <a href="https://sci.pdn.ac.lk/botany/staff/Deepthi-Yakandawala" target="_blank" rel="noreferrer noopener">Deepthi Yakandawala</a>, a botanist at the <a href="https://www.pdn.ac.lk/" target="_blank" rel="noreferrer noopener">University of Peradeniya</a>. 



Finding this fungus serves as a reminder that big discoveries can arise from simple outdoor observations. 



Ordinary people who keep an eye out for odd growths or strange insects can become an informal research team. Sharing photos and talking with experts can lead to remarkable breakthroughs.



Fungi are more than just mushrooms on pizza or molds that spoil food. They drive nutrient cycling, help decompose organic matter, and form critical symbiotic ties with plants.



Many are valuable for medicine and agriculture. Yet, they often remain ignored in biodiversity studies.



<h2 class="wp-block-heading" id="h-what-s-next-for-stinkhorn-mushrooms">What's next for stinkhorn mushrooms?</h2>



Experts say hope and vigilance must go hand in hand. Many species are still at risk, even if a few pop up again.



Keeping habitats intact and curbing pollution are ways to help the organisms we rarely see. It takes broad support to protect hidden life forms, from local gardens to global policy changes.



The family who spotted the fungus could have brushed it aside as a random growth. Instead, they chose to investigate.



That small action set off a scientific investigation and gave researchers fresh insight into an old record. It also reminds us that valuable nature sightings can happen anywhere.



Mycologists believe there may be more overlooked fungi in various regions. Using social media or identification apps like <a href="https://www.earth.com/earthsnap/" target="_blank" rel="noreferrer noopener">Earthsnap</a> can bridge the gap between citizens and scientists.



Strong cooperation between everyday observers and institutions can speed up new findings. With that kind of teamwork, many lost organisms might get a second chance.

Family photographs a rare 'red cane' and scientists confirm it's a fungus thought to be extinct

One chilly day, a family in Sri Lanka came upon...

Climate scientists say rising temperatures can reduce the availability and nutritional quality of dairy grass. Producers then turn to alternative feeds, including corn-based silage, to maintain production.



In a recent investigation, Dr. Matthieu Bouchon, an expert at <a href="https://www.inrae.fr/en" target="_blank" rel="noreferrer noopener">INRAE</a> - National Research Institute for Agriculture, Food and Environment, studied how these changes in feeding practices influence both <a href="https://www.earth.com/news/extreme-heat-makes-dairy-cows-produce-less-milk/" target="_blank" rel="noreferrer noopener">milk</a> yield and the resulting cheese.



Dr. Bouchon was part of a team that analyzed nutritional profiles and taste notes across different feeding setups.



<h2 class="wp-block-heading" id="h-how-climate-change-affects-cow-feed">How climate change affects cow feed</h2>



Drought is bad news for many pasture-reliant farms. When rains fade, grass doesn’t grow as usual, so farmers scramble to bolster cow diets with stored feeds or more concentrated rations.



Climate impacts force them to get inventive. That often means adding more corn silage to keep <a href="https://www.earth.com/news/grazing-animals-have-an-unexpected-role-in-climate-change/" target="_blank" rel="noreferrer noopener">cows</a> in good shape, but it can lead to a drop in grass-based components that affect milk’s natural composition.



<h2 class="wp-block-heading" id="h-grass-intake-and-dairy-nutrients">Grass intake and dairy nutrients</h2>



Farmers are keen on maximizing nutrients in milk. The study team discovered a strong tie between higher grass intake and better fatty acid content.



“The results showed that the more grass the cows ate, the richer the <a href="https://www.earth.com/news/ai-paves-the-way-for-climate-conscious-farming/" target="_blank" rel="noreferrer noopener">milk</a> and cheese were in omega-3 fatty acids, which are beneficial to human health,” stated Dr. Bouchon.



Switching to corn-based rations can still yield a decent amount of milk. Yet the subtle nutritional goodies in <a href="https://pubmed.ncbi.nlm.nih.gov/16960079/" target="_blank" rel="noreferrer noopener">grass</a> may slip away if it becomes a minor part of the diet.



<h2 class="wp-block-heading" id="h-cow-feed-changes-cheese">Cow feed changes cheese </h2>



Consumers often favor the special shade and softness of artisanal cheese. Grass helps deliver that yellowish tinge and a smoother, melt-in-the-mouth feel.



“Cows fed on grazed grass produced smoother, yellower, more aromatic cheeses, while cows fed little to no grass produce whiter, firmer cheeses with milder flavors,” said Dr. Bouchon.&nbsp;



<h2 class="wp-block-heading" id="h-distinct-flavors-of-cheese">Distinct flavors of cheese</h2>



Minimizing fresh grass in a herd’s diet can make the final dairy product less appealing. This outcome matters not just for foodies but also for farmers marketing distinctive <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5867552/" target="_blank" rel="noreferrer noopener">cheeses</a>.



Many shoppers pick grass-fed labels expecting distinct flavors. When producers reduce fresh grass in favor of silage or hay, the cheese may lose that familiar aroma.



A cheese that once tasted bold or slightly grassy can end up with a blander profile. Texture often changes too, as the fats and proteins shift under modified feeding patterns.



<h2 class="wp-block-heading" id="h-practical-worries-for-farmers">Practical worries for farmers</h2>



Dairy farms run on slim profit margins. Any slip in milk yield or cheese appeal can hurt business, but ignoring drought conditions isn’t an option either.



Balancing feed mixes becomes a juggling act. More grass means tastier cheese, but a parched field can’t always supply what's needed, so producers face a hard call.



<h2 class="wp-block-heading" id="h-feed-changes-affect-cow-digestion">Feed changes affect cow digestion</h2>



Each feed ingredient, whether hay or silage, can affect <a href="https://www.nature.com/articles/s41392-022-00974-4" target="_blank" rel="noreferrer noopener">microbiota</a> inside a cow’s rumen. This intricate environment helps break down cellulose and produce nutrients for the cow.



If farmers switch abruptly to corn-based rations, the cow’s digestive system may take time to adjust. Subtle changes in the rumen can ripple through to the milk in surprising ways.



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



Nobody wants a rubbery or flavorless cheese on their plate. Folks who appreciate artisanal dairy should keep an eye on how climate issues and diet adjustments shape their favorite products.



While these shifts might not stand out in mass-produced cheese, small-scale operations often rely on the tastes derived from high-grass diets. Flavor can be a big selling point.



<h2 class="wp-block-heading" id="h-feeding-strategies-influence-dairy-yield-nbsp">Feeding strategies influence dairy yield&nbsp;</h2>



Herd nutrition is more complicated than many realize. Different cows have varying needs depending on genetics, lactation stage, and climate conditions.



Producers factor in how each feed ingredient influences both milk quantity and milk quality. These trade-offs can make or break the end product’s sensory profile.



<h2 class="wp-block-heading" id="h-adapting-cow-feed-to-drought-conditions">Adapting cow feed to drought conditions</h2>



Some farmers are testing new grass varieties said to handle hot spells better. Others look at advanced grazing strategies or water conservation tactics to maintain fields during dry months.



At the same time, research teams share data to guide farmers on how best to tweak feed ingredients. The aim is to protect both milk output and that prized cheese taste.



<h2 class="wp-block-heading" id="h-preserving-dairy-grass">Preserving dairy grass </h2>



Shoppers see words like omega-3 on labels but don’t always know how production methods affect those nutrients. Many prefer products that combine solid nutrition with a pleasing taste, color, and aroma.



Farmers who manage to preserve grass can maintain that balance. Even modest amounts of fresh forage appear helpful to keep cheese palatable and nutritionally robust.



<h2 class="wp-block-heading" id="h-beyond-the-pasture">Beyond the pasture</h2>



Climate concerns won’t vanish overnight. Researchers are tracking how these feeding adjustments ripple across entire food chains, from soil microbes to final cheese properties.



While not every farm can rely on grass alone, preserving its presence seems vital for those aiming for standout cheese. This is especially true for dairy regions with a cultural heritage tied to lush fields.



<h2 class="wp-block-heading" id="h-dairy-production-amid-climate-change">Dairy production amid climate change</h2>



With each passing year, dryness threatens more farmland. Creative solutions and careful ration decisions may hold the key to maintaining the hallmark traits that grass-based cheeses are known for.



Ongoing research may soon offer farmers new strategies to keep cows healthy while reducing their environmental impact. Whether large or small, dairy producers must continue to adapt to meet these evolving challenges.

Popular types of cheese are beginning to taste different due to what cows are eating

Climate scientists say rising temperatures can reduce the availability and...

Hummingbirds normally patrol the scarlet blooms of the western United States, sipping nectar and carrying pollen from one monkeyflower to the next.



Yet along the outer edges of that crimson range botanists once noticed something odd: scattered stands of Mimulus cardinalis and Mimulus verbenaceus (two monkeyflower species) had traded their fiery petals for butter-yellow ones.



Earlier fieldwork hinted that <a href="https://www.earth.com/news/bumblebees-show-surprising-adept-teamwork-skills/">bumblebees</a>, not hummingbirds, seemed drawn to these rare morphs, but decades ago researchers lacked the genomic and biochemical tools to learn why.



A team led by Kelsey Byers at the <a href="https://www.jic.ac.uk/">John Innes Center</a> has now reopened the case. In a recent study, the group combined controlled pollinator trials, floral chemistry, and comparative genetics. 



The findings reveal how color, scent, and shape interact when a plant begins shifting from one pollination strategy to another. Researchers documented an adaptive walk - evolution’s slow path from ancestral traits to new ecological niches.



<h2 class="wp-block-heading" id="h-bees-prefer-a-yellow-color">Bees prefer a yellow color</h2>



Inside climate-regulated glasshouses, the researchers offered captive bumblebees paired arrays of yellow and red flowers from both species.



The insects showed a clear preference, visiting yellow twice as often as red. 



Chemical analysis then uncovered a clue: the yellow morphs emitted higher volumes of volatile compounds, a likely adaptation because bees, unlike <a href="https://www.earth.com/news/hummingbirds-have-an-incredible-strategy-to-survive-food-shortages/">hummingbirds</a>, rely heavily on scent when foraging.



<h2 class="wp-block-heading" id="h-bees-struggle-despite-color">Bees struggle despite color</h2>



Color and fragrance alone do not guarantee reproductive success. High-speed video revealed that bees wrestled awkwardly with the tubular corollas, structures sculpted through millennia of hummingbird visitation.



Many bees tore the delicate petals while probing for nectar and often failed to brush against the floral reproductive organs, a prerequisite for <a href="https://www.earth.com/news/ai-is-transforming-pollen-science-and-health-planning/">pollen</a> transfer. As a result, the bees’ frequent visits did not translate into efficient pollination.



The researchers interpret this mismatch as evidence that the yellow monkeyflowers represent an early stage in the switch from bird to bee service: color mutation and heightened scent have arisen first, but corolla architecture has yet to catch up.



<h2 class="wp-block-heading" id="h-different-genes-same-traits">Different genes, same traits</h2>



A long-standing question was whether the yellow trait in the two Mimulus species emerged through the same molecular pathway. The team’s genomic scans show the answer is partly yes and partly no.



Both species boosted yellow and orange carotenoid pigments by changes to the same suite of genes, a textbook example of convergent evolution. Yet other alterations - loss of red anthocyanin pigments and shifts in scent chemistry - arose through different genetic tweaks in each lineage.



“Even though these species are closely related, they have followed different paths to the same endpoint for many of their traits,” Byers said.



“We have identified ways that flowers can change and affect pollinator visitation, as well as some genetic pathways that can underlie these changes and how they have evolved in different but closely related species.”



<h2 class="wp-block-heading" id="h-a-timeline-for-trait-evolution">A timeline for trait evolution</h2>



Because floral color strongly influences pollinator choice, mutations in pigment genes may surface first during a pollinator shift. Secondary adjustments, such as boosted scent emission or re-shaped petals, could then fine-tune the interaction.



The Mimulus data support that sequence. Large-effect color mutations preceded subtler changes in odor bouquet, while corolla morphology still lags behind, leaving the bee–flower fit imperfect. 



The researchers argue that this hierarchy of changes - big steps followed by smaller refinements - may be typical whenever plants embark on new mutualisms.



<h2 class="wp-block-heading" id="h-bee-friendly-color-affects-farming">Bee-friendly color affects farming</h2>



Pollinator partnerships underpin terrestrial <a href="https://www.earth.com/news/effective-conservation-efforts-key-to-saving-biodiversity/">biodiversity</a> and sustain many food crops. By dissecting how wild species recalibrate those relationships, scientists gain conceptual tools for conservation and agriculture.



“By understanding how traits evolve in the wild, we understand biodiversity better, and by understanding how these traits can be affected by plant genetics, we have the foundation of the ability to engineer traits to impact pollinator preference and thus crop yield,” Byers said.



Tuning color and scent may let breeders align crops with local pollinators, improving output without extra chemicals.



<h2 class="wp-block-heading" id="h-next-on-the-research-agenda">Next on the research agenda</h2>



The team plans gene-editing and transgenic experiments to verify the precise functions of the carotenoid biosynthesis genes that acted convergently and the anthocyanin regulators that diverged.



They are also surveying another yellow population of Mimulus cardinalis to see whether it repeated the same genetic tricks or invented new ones. Such comparative work will refine our picture of how predictable - or idiosyncratic - evolutionary innovation can be.



<h2 class="wp-block-heading" id="h-floral-traits-still-changing">Floral traits still changing</h2>



For now the yellow monkeyflowers stand as living waypoints on an evolutionary journey not yet complete. Bumblebees like their color and perfume, but the floral entrance still suits a hovering hummingbird more than a burrowing bee.



With time and mutations, petal tubes may evolve to guide bees directly to stamens and stigmas. Should that happen, future botanists might find a fully bee-adapted Mimulus lineage where once only hummingbirds ruled - and they will have these early studies to trace how the transformation began.



The study is published in the journal <a href="https://www.nature.com/articles/s41467-025-57639-3">Nature Communications</a>.

These wildflowers changed color to attract bees

Hummingbirds normally patrol the scarlet blooms of the western United...

Crops with genetically enhanced root systems could potentially help remove carbon dioxide from the atmosphere. The idea seems simple: grow crops with bigger roots that can store more carbon dioxide under the soil. 



But can this actually help with the fight against climate change? A new study says yes - but with some caveats.



In a new report from researchers at the <a href="https://ucsd.edu/" target="_blank" rel="noreferrer noopener">University of California San Diego</a>, scientists explain how genetically enhanced crops with larger root systems could become a practical way to remove large amounts of carbon dioxide from the atmosphere. 



The researchers, based at Scripps Institution of Oceanography and the School of Global Policy and Strategy, also explored how this method compares to other <a href="https://www.earth.com/news/ocean-based-carbon-dioxide-removal-may-not-be-effective/" target="_blank" rel="noreferrer noopener">carbon removal</a> strategies. 



<h2 class="wp-block-heading" id="h-why-we-need-rapid-carbon-removal">Why we need rapid carbon removal</h2>



According to estimates from the Intergovernmental Panel on Climate Change (IPCC), the world must remove between five and 16 billion tons of <a href="https://www.earth.com/news/rising-carbon-dioxide-makes-crops-grow-bigger-but-less-nutritious/" target="_blank" rel="noreferrer noopener">carbon dioxide</a> every year to have a shot at keeping the climate stable. That’s in addition to reducing how much we emit in the first place. 



If we don’t act fast, the world could see widespread disasters, including severe storms, failing crops, worsening disease outbreaks and flooding due to rising sea levels. 



So far, however, there hasn’t been much research on how fast carbon removal methods could realistically scale up in the real world and help to bring the climate back into balance.



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



That’s where carbon-enhanced crops come in. These genetically modified plants have larger root systems designed to <a href="https://www.earth.com/news/sea-level-rises-wetlands-store-carbon/" target="_blank" rel="noreferrer noopener">store more carbon in the soil</a>. 



The researchers ran a detailed analysis of how much carbon these crops could help remove if widely adopted. They found that, within a period of 13 years of rollout, these crops could remove between 0.9 and 1.2 gigatons of CO2 annually.



That’s about seven times the total amount of carbon offsets that are currently supplied to the global market.



“There is a consensus in the scientific community that we will have to scale CDR [carbon dioxide removal] substantially to reach net zero - on top of drastically reducing our <a href="https://www.earth.com/news/greenhouse-gas-emissions-reach-another-all-time-high/" target="_blank" rel="noreferrer noopener">greenhouse gas emissions</a>,” said lead author Daniela Faggiani-Dias.



“Yet, research on how CDR can realistically scale - considering not only technical limits, but also scale-up speed and feasible pathways - is very thin. And this is what is new about our study."



“We provide a detailed analysis of the CDR scaling challenge and propose a framework to estimate how quickly and to what extent emerging, highly uncertain technologies might scale. 



According to Faggiani-Dias, even though the analysis focuses on carbon-enhanced crops, the framework is generalizable across CDR approaches and helps to surface key uncertainties in scale-up potential.



<h2 class="wp-block-heading" id="h-learning-from-past-technological-advances">Learning from past technological advances</h2>



The team looked to the past to understand how fast new technologies typically spread. They studied how other agricultural advances - like hybrids, pesticides, fertilizers, and crop rotation - caught on over time.



One of the most relevant comparisons was with <a href="https://www.earth.com/news/gene-modification-can-create-better-tomatoes-eggplants-but-should-we-do-it/" target="_blank" rel="noreferrer noopener">genetic modification</a>. Like carbon-enhanced crops, genetically modified crops promised benefits to farmers and the agricultural supply chain. But the rollout wasn’t smooth.



In countries that allowed genetically modified crops, it took about 11 years to go from early adoption to widespread use. Even then, only 13% of the world’s farmland currently grows these types of crops. Regulations and public concerns have slowed wider acceptance. 



The researchers say carbon-enhanced crops could face the same hurdles unless there are strong incentives, such as carbon credits, for countries that use them.



<h2 class="wp-block-heading" id="h-why-crops-may-be-the-fastest-fix">Why crops may be the fastest fix</h2>



Compared to other carbon removal strategies - such as storing carbon in rock or filtering it from air or oceans - enhanced crops have a head start. They can be adopted using existing farm infrastructure and technologies.



Farmers are already familiar with trying new crop techniques, and there's a built-in industry ready to support new seed technologies. Plus, the soil is often depleted of carbon, making it a good place to store more.



Other strategies would potentially require the establishment of entirely new industries before they could be successfully implemented at scale. This could take years to test and verify, considering that some of these strategies are still in their infancy.



That’s why crops with enhanced roots are seen as one of the fastest and most realistic tools for carbon removal - although they would still not be effective enough on their own.



<h2 class="wp-block-heading" id="h-crops-are-only-part-of-the-solution">Crops are only part of the solution</h2>



Faggiani-Dias emphasized that this approach is just one piece of the climate solution puzzle. She noted that the benefit of carbon-enhanced crops could be significant, but not enough on its own. 



According to Faggiani-Dias, these efforts should be seen as just one component of a broader strategy to decarbonize the global economy.



The full study was published in the journal <a href="https://iopscience.iop.org/article/10.1088/1748-9326/adc31b" target="_blank" rel="noreferrer noopener">Environmental Research Letters</a>.

Genetically enhanced crops could help fight climate change

Crops with genetically enhanced root systems could potentially help remove...

Food allergies have become increasingly common, affecting roughly one in 13 children, as reported by Food Allergy Research and Education (FARE). With such a rise, scientists continue to explore how maternal diets might influence allergy risk in infants. 



Recent research in Finland sheds light on a surprising connection between avocado consumption during pregnancy and reduced food allergy risk in infants.



A study involving 2,272 mother-child pairs, conducted over nearly a decade, uncovered a striking finding. Infants whose mothers consumed avocados during pregnancy had a 43.6% lower chance of developing food allergies by 12 months. 



The study accounted for <a href="https://www.earth.com/news/why-omega-3-deficiency-is-rising-worldwide/" target="_blank" rel="noreferrer noopener">variables</a> such as maternal age, smoking status, and education - yet the link remained consistent.



<h2 class="wp-block-heading" id="h-avocados-lower-allergy-risk">Avocados lower allergy risk</h2>



For years, researchers have explored how specific dietary patterns during pregnancy might influence infant allergy risk. However, individual foods like avocados have not received the same level of scrutiny. 



The Finnish study aimed to fill that gap. The team utilized an online food frequency questionnaire (FFQ) to assess maternal avocado intake during the first and third trimesters. 



Participants who reported any avocado <a href="https://www.earth.com/news/food-production-more-difficult-climate-change-plant-pollinators/" target="_blank" rel="noreferrer noopener">consumption</a> were classified as consumers, while those who did not became non-consumers.



The analysis revealed a significant contrast. Among non-consumers, 4.2% of infants developed food allergies. In comparison, only 2.4% of infants whose mothers consumed avocados experienced the same outcome.



The reduction in allergy risk remained significant even after adjusting for various maternal health factors .



<h2 class="wp-block-heading" id="h-avocado-research-offers-hope">Avocado research offers hope</h2>



“As a caregiver, the growing prevalence of food allergy feels very scary and out of my control,” said Sari Hantunen, senior lecturer at the <a href="https://www.uef.fi/en" target="_blank" rel="noreferrer noopener">University of Eastern Finland</a>.



“There is no cure for food allergy, but promising prevention and therapeutic strategies are in development as well as emerging research such as this."



”Based on these findings, it’s encouraging to know that eating avocados may provide even more value to maternal and children’s health, beyond the benefits that have already been established through scientific research.”



<h2 class="wp-block-heading" id="h-tracking-avocado-and-allergy">Tracking avocado and allergy</h2>



The Kuopio Birth Cohort (KuBiCo) provided a rich dataset for analysis. Researchers recruited pregnant women during routine first-trimester appointments at <a href="https://pshyvinvointialue.fi/web/en/kuopio-university-hospital" target="_blank" rel="noreferrer noopener">Kuopio University Hospital</a>. Data collection continued until November 2022, capturing dietary intake throughout the first and third trimesters.



Mothers completed FFQs that detailed food consumption over the past three months. The FFQ specifically assessed avocado intake, classifying participants as consumers or non-consumers.



After birth, researchers tracked infants to assess allergic outcomes, including <a href="https://www.earth.com/news/new-therapy-may-help-reduce-peanut-allergies-in-children/" target="_blank" rel="noreferrer noopener">food</a> allergies, eczema, rhinitis, and wheezing. Even after adjusting for variables like maternal age, smoking, and breastfeeding duration, the data maintained its significance. 



Infants of non-consumers showed a 4.2% allergy rate, while those of avocado consumers showed a 2.4% rate .



<h2 class="wp-block-heading" id="h-who-choose-avocados">Who choose avocados?</h2>



Avocado consumers shared common traits that distinguished them from non-consumers. They tended to be older and more educated. They also reported longer breastfeeding durations and higher diet quality scores.



These women generally had lower BMI levels in the first trimester and were less likely to undergo caesarean deliveries. Researchers noted that these trends might reflect broader health-conscious behaviors rather than avocado <a href="https://www.earth.com/news/ai-is-transforming-pollen-science-and-health-planning/" target="_blank" rel="noreferrer noopener">consumption</a> alone .



Avocados pack essential nutrients that may benefit both maternal and infant health. Each serving provides 9.25 grams of dietary fiber, supporting gut health and potentially influencing immune responses.



Additionally, avocados contain 2.6 mg of vitamin E, an antioxidant linked to immune function, and 0.93 mg of zinc, which plays a role in immune development. Lutein, a carotenoid crucial for eye health, also features prominently in avocados.



The nutrient profile aligns well with dietary patterns like the Mediterranean diet, previously associated with lower allergy risks in offspring. While the study focused solely on avocados, researchers suggest that other nutrient-dense foods may offer similar protective effects .



<h2 class="wp-block-heading" id="h-consuming-avocados-for-allergy-prevention">Consuming avocados for allergy prevention</h2>



The Dietary Guidelines for Americans recommend that pregnant women consume 2 ½ to 3 ½ cups of vegetables daily. Avocados, with their nutrient density, count as a full cup per serving.



For toddlers aged 12-23 months, the guidelines suggest 2/3 to 1 cup of vegetables each day. With its rich nutrient profile, a single avocado serves as a practical choice to meet these recommendations without the need for supplements.



Despite the promising findings, the study did not identify any significant links between avocado consumption and other allergic conditions like rhinitis, eczema, or wheezing. 



The focus on food allergies yielded notable results, but the other conditions showed no significant differences between consumers and non-consumers.



<h2 class="wp-block-heading" id="h-expanding-the-research">Expanding the research</h2>



The researchers caution against overgeneralizing the findings. While avocados may contribute to reduced food allergy risk, the mechanisms remain unclear. 



Further studies could clarify whether specific nutrients within avocados influence immune development and whether similar effects extend to other foods .



The study opens doors for future research that could extend beyond infancy. Tracking infants beyond the first year of life may provide insights into how early dietary exposures shape allergy risk throughout childhood.



Additionally, examining other nutrient-dense foods with similar profiles, such as nuts, seeds, or leafy greens, could help determine whether the observed effects result from specific nutrients or broader dietary patterns. 



Understanding these connections could refine dietary recommendations for pregnant women, offering clearer guidance on foods that may reduce allergy risk in infants.

As food allergies continue to rise, identifying preventive strategies during pregnancy remains a critical focus. This Finnish study suggests that avocados, with their nutrient-rich profile, may play a role in reducing food allergy risk in infants.



While the study does not establish causality, it highlights the potential impact of nutrient-dense foods during pregnancy - a time when maternal diet can leave lasting imprints on infant health. 



Further research will clarify whether these findings hold across diverse populations and whether other foods offer similar benefits.

Eating avocados during pregnancy reduces baby's allergy risk

Food allergies have become increasingly common, affecting roughly one in...

Termites are often overlooked in rainforest restoration, where the focus is usually on planting trees. But what if the key to a thriving forest lies not in the canopy above, but in the soil below - and in the insects that crawl through it?



A new study reveals that termites, often seen as pests, might actually be essential allies in helping young rainforests flourish. 



Scientists from the <a href="https://www.caryinstitute.org/" target="_blank" rel="noreferrer noopener">Cary Institute of Ecosystem Studies</a> and the University of Queensland in Australia have found that these tiny decomposers are missing - or at least lagging behind - in forests that have been replanted, even more than a decade after restoration began.



<h2 class="wp-block-heading" id="h-forests-need-more-than-trees">Forests need more than trees</h2>



“People tend to think that by just planting a <a href="https://www.earth.com/news/tree-species-diversity-makes-forests-more-productive/" target="_blank" rel="noreferrer noopener">diversity of trees</a>, these rainforests will regenerate,” said Baptiste Wijas, a postdoctoral fellow at Cary Institute and visiting academic at the University of Queensland. 



“But it's worth thinking about, should we actually be putting in other organisms as well, to restore other ecosystem processes that help the forest function? In the context of rainforest regeneration, no one really thinks about it at all.”



That question matters more than ever. As more land is reforested in efforts to combat climate change and restore ecosystems, it’s crucial to understand what makes a forest actually function. 



Decomposers like termites and <a href="https://www.earth.com/news/fungi-can-think-and-make-smart-decisions-without-a-brain/" target="_blank" rel="noreferrer noopener">fungi</a> play a critical role in cycling nutrients and carbon. Without them, the soil might lack the resources young trees need to grow.



<h2 class="wp-block-heading" id="h-testing-the-forest-floor">Testing the forest floor</h2>



To understand how well decomposers were rebounding, the research team set up a simple but telling experiment. They placed wooden blocks in three different forest settings in Australia’s Daintree Rainforest. One was a pristine <a href="https://www.earth.com/news/forest-microclimates-impact-bird-species-diversity/" target="_blank" rel="noreferrer noopener">old-growth forest</a>. 



The other two were replanted sites - one restored in 2010, the other in 2014 - on land that had been cleared for agriculture decades ago and later abandoned. The replanting was carried out by a nonprofit organization called Rainforest Rescue.



For four years, the team checked on the wooden blocks every six months. They looked for signs of fungi, termites, or both, and tracked how fast the wood was breaking down.



<h2 class="wp-block-heading" id="h-a-wet-and-wild-challenge">A wet and wild challenge</h2>



The fieldwork was anything but easy. “You’re sweating all the time, and there are plants that want to attack you everywhere,” said Wijas. 



In one year alone, the team faced a series of <a href="https://www.earth.com/news/droughts-and-extreme-weather-events-are-escalating/" target="_blank" rel="noreferrer noopener">extreme weather events</a> - drought, floods, fires, and “a zombie cyclone that caught us twice,” said Cary Institute senior scientist Amy Zanne. “It was an epic, biblical year.”



Despite these challenges, the team made a surprising discovery. They expected that termites would be thriving in all the rainforests and that fungi would struggle more in the younger sites. But the results were the opposite.



<h2 class="wp-block-heading" id="h-fungi-thrive-while-termites-struggle">Fungi thrive while termites struggle</h2>



Fungi were resilient. They performed almost as well in the replanted forests as in the old-growth site, though they were a bit slower in the youngest forest. 



Termites, however, were another story. While they were present at all three sites, they decomposed wood at a much slower rate in the replanted forests. Even 12 years after <a href="https://www.earth.com/news/success-story-reforestation-has-helped-keep-the-eastern-us-relatively-cool/" target="_blank" rel="noreferrer noopener">reforestation</a> began, the termite-driven decay lagged behind.



The researchers suggest several possible reasons: termite colonies in the replanted areas may be fewer, smaller, less diverse, or less mature.



That’s a problem, because slow decomposition can mean nutrients and carbon aren’t returning to the soil quickly enough. And that could stunt forest growth.



<h2 class="wp-block-heading" id="h-a-radical-idea-importing-insects">A radical idea: Importing insects</h2>



To fix the problem, the scientists have a bold proposal. They suggest bringing logs from old-growth forests into younger forests to introduce decomposers and give existing ones more to eat.



“A young, regenerating forest doesn’t have a lot of deadwood in it,” Zanne explained. “So if you bring in these logs, you’re giving them some food to tide them over while they wait for parts of trees to start falling down.”



They’re also thinking even bigger: what about transplanting entire termite mounds? “That’s something that no one's really thought about either,” said Wijas.



<h2 class="wp-block-heading" id="h-rethinking-termites-in-forests">Rethinking termites in forests</h2>



Convincing forest managers to welcome termites into their restoration plans won’t be easy.



“Many people - forest managers included - don’t really like termites,” said Wijas. “But they play an important role in having a healthy forest.”



Zanne pointed out that most termites get a bad rap for no reason. "Only about 3% of termites are known to damage human homes. Very little is known about the other 97%.”



<h2 class="wp-block-heading" id="h-more-than-just-decomposers">More than just decomposers</h2>



In fact, termites might be doing even more good than we think. 



“We think termites might be locking up carbon in their nests,” said Wijas. “When they eat wood, they’re not able to digest all of it, and so the feces they use to build their nests could be quite carbon-rich. They may even lock up more carbon than they emit, but we just don’t know yet.”



Termites may also help trees grow by partnering with nitrogen-fixing <a href="https://www.earth.com/news/bacteria-pass-down-memories-to-future-generations/" target="_blank" rel="noreferrer noopener">bacteria</a>, which convert nitrogen into a form plants can use.



“Termites and fungi are absolutely critical to forest function,” said Zanne. “It would be interesting to see who else returns to the regenerating forests if the termites are there - perhaps ants, lizards, and gliders that eat termites. Right now we just don't have any idea whether these organisms are coming back in these systems.”



As the search continues for ways to speed up rainforest recovery, termites may prove to be unlikely but vital allies. The next time we think about rebuilding a forest, we might want to think beyond trees—and start thinking about termites too.

Termites play an unexpected role in rainforest revival

Termites are often overlooked in rainforest restoration, where the focus...

A new investigation at a high‑Andean temple reveals that the distant ancestors of the Inca wielded psychoactive plants as a political tool. 



Archaeologists have uncovered bone tubes still coated with traces of mind‑altering snuff, showing that Chavín lords used controlled visions to cement their rule almost three millennia ago.



The discovery comes from a project led by researchers at the <a href="https://www.ufl.edu/">University of Florida</a>, <a href="https://www.stanford.edu/">Stanford University</a>, and partner institutions across South America. 



The experts analyzed artifacts from Chavín de Huántar, a vast ceremonial center that sits 10,000 feet above sea level in the Peruvian Andes.



<h2 class="wp-block-heading" id="h-ancient-use-of-psychoactive-plants">Ancient use of psychoactive plants</h2>



Inside narrow passageways and hidden rooms, the team found small hollow bones carved into elegant inhalation tubes. 



Chemical testing detected nicotine from wild tobacco relatives and residue from vilca beans, whose potent compounds are related to DMT.



Microscopic work confirmed plant particles embedded in the ancient surfaces. The date of the deposits makes this the oldest direct evidence for psychoactive plant use yet known in the high Andes.



<h2 class="wp-block-heading" id="h-rituals-shaped-social-order">Rituals shaped social order</h2>



The placement of the tubes mattered. They were sealed within private chambers that could hold only a handful of people. That setting implies exclusive ceremonies, not widespread communal feasts.



The evidence matches a broader pattern of Chavín architecture, which funnels visitors through labyrinths toward dimly lit sanctuaries where sights, sounds, and fragrances overwhelm the senses.



“Taking psychoactives was not just about seeing visions. It was part of a tightly controlled ritual, likely reserved for a select few, reinforcing the social hierarchy,” said Daniel Contreras, an anthropological archaeologist at the University of Florida and a co‑author of the study.



<h2 class="wp-block-heading" id="h-chavin-rituals-meant-to-stun">Chavín rituals meant to stun</h2>



Stone corridors at Chavín already distort light and echo footsteps. Researchers have also recovered giant trumpets fashioned from imported conch shells. 



The deep blasts of those horns, amplified by the tunnels, would have rattled bone. Add intense <a href="https://www.earth.com/news/understanding-presence-hallucinations-impact-on-social-perception/">hallucinations</a>, and followers might have felt a raw presence of gods or spirits.



“The supernatural world isn’t necessarily friendly, but it’s powerful,” Contreras said. “These rituals, often enhanced by psychoactives, were compelling, transformative experiences that reinforced belief systems and social structures.”



By staging such events, leaders wrapped their authority in cosmic mystery. Participants emerged convinced that rank and building labor served a higher design. 



Craftspeople who carved the monumental granite slabs and farmers who fed the workforce likely saw themselves as part of a living myth, not as servants under duress.



<h2 class="wp-block-heading" id="h-belief-used-for-power">Belief used for power</h2>



“One of the ways that <a href="https://www.earth.com/news/wealth-inequality-began-shaping-human-societies-10000-years-ago/">inequality</a> was justified or naturalized was through ideology - through the creation of impressive ceremonial experiences that made people believe this whole project was a good idea,” Contreras said.



The snuff tubes thus fit a larger strategy. Earlier Andean settlements show few signs of strict hierarchy. By Chavín times, around 800 BCE, society had acquired priests, skilled artisans, and regional trade routes. 



Control over sacred knowledge, including plant lore, helped elites turn soft power into hard architecture and coordinated labor.



<h2 class="wp-block-heading" id="h-psychoactive-plant-mixture">Psychoactive plant mixture</h2>



Vilca beans grow in lowland forests far from Chavín’s icy heights. Their presence points to long‑distance exchange networks and to careful botanical skill.



When roasted, mixed with lime, and inhaled, the powder produces vivid visions, rapid heartbeat, and disorientation. 



Wild tobaccos add <a href="https://www.earth.com/news/nicotine-pouches-are-a-new-dangerous-trend-among-teens/">nicotine</a>’s stimulant rush and sharp aroma. Combined, these plants could propel users into what seemed another realm.



<h2 class="wp-block-heading" id="h-bringing-invisible-details-to-light">Bringing invisible details to light</h2>



Contreras has worked at the site for nearly 30 years in a project directed by Stanford archaeologist John Rick.



Their excavations have mapped hidden galleries, sculpted stone icons, and water channels that once gurgled beneath temple floors. The new chemical analyses bring invisible details to light, showing not only what people did but also what they felt.



“It’s exciting that ongoing excavations can be combined with cutting‑edge archaeological science techniques to get us closer to understanding what it was like to live at this site,” Contreras said.



<h2 class="wp-block-heading" id="h-from-vision-to-empire">From vision to empire</h2>



The Chavín phenomenon spread a shared artistic style and worldview up and down the Peruvian coast and sierra. Later Andean states inherited its taste for grand plazas, stone imagery, and elite ritual.



By demonstrating the intentional use of psychoactive plants in tightly managed settings, the study bridges the gap between small egalitarian hamlets and the vast empires that eventually ruled the Cordillera.



<h2 class="wp-block-heading" id="h-a-modern-glimpse-of-ancient-minds">A modern glimpse of ancient minds</h2>



Today, visitors to Chavín de Huántar walk through restored corridors where carved fangs and staring eyes still pierce the dim light. 



Knowing that select priests once knelt here, inhaled potent smoke, and proclaimed cosmic truths changes how we read those walls.



The <a href="https://www.earth.com/news/archaeologists-find-hallucinogenic-seeds-in-ancient-bones-black-henbane/">bone</a> tubes, simple yet sophisticated, remind us that chemistry, belief, and social order have long been intertwined. In the high Andes, <a href="https://www.earth.com/news/meditation-reveals-common-altered-states-of-consciousness/">altered consciousness</a> was more than a personal journey - it was statecraft written in breath and stone.



The study is published in the journal <a href="https://www.pnas.org/doi/10.1073/pnas.2425125122">Proceedings of the National Academy of Sciences</a>.

How psychoactive plants helped build an ancient empire

A new investigation at a high‑Andean temple reveals that the...

Marijuana has intrigued people for decades, especially as more places allow it for medical or recreational use. Many see it as a natural product with relaxing properties, yet scientists have been eager to uncover how it might alter the body in subtle ways.



Researchers tracked the cannabis habits of more than 1,000 U.S. adults over roughly two decades. The team included epidemiologist Lifang Hou from <a href="https://www.northwestern.edu/" target="_blank" rel="noreferrer noopener">Northwestern University</a>, who analyzed blood samples at two points to search for signs that cannabis use may shift genetic markers.



<h2 class="wp-block-heading" id="h-how-marijuana-alters-dna">How marijuana alters DNA</h2>



The epigenome includes chemical modifications on DNA that can affect how genes work. These modifications, such as <a href="https://www.nature.com/articles/npp2012112" target="_blank" rel="noreferrer noopener">DNA methylation</a>, do not alter the underlying genetic code but can change how active certain sections of DNA are.



Studies have suggested that environmental factors like diet or toxins can impact these epigenetic markers. New findings now propose that cannabis use may leave an imprint, too.



“We observed associations between cumulative marijuana use and multiple epigenetic markers across time,” explained Hou. The markers appeared in people who reported using cannabis in the short term as well as across many years.



While these associations are intriguing, the study does not confirm that <a href="https://www.earth.com/news/cannabis-use-during-pregnancy-rewires-the-fetal-brain/">cannabis</a> is the direct cause. The researchers emphasize that other behaviors or factors could be partly responsible for the patterns seen in those genetic switches.



<h2 class="wp-block-heading" id="h-genetic-response-to-cannabis-and-tobacco">Genetic response to cannabis and tobacco</h2>



One of the most striking findings was a consistent methylation marker that has already been linked to tobacco use. The same signal appeared in cannabis users, hinting that the body may respond to both substances in a similar way at the genetic level.



This overlap raises questions about whether cannabis and tobacco trigger the same biological pathways or if the presence of smoke itself is responsible for the epigenetic shift. 



More studies could help clarify whether these changes stem from the substances themselves or the act of inhalation.



<h2 class="wp-block-heading" id="h-could-these-markers-predict-health-risks">Could these markers predict health risks?</h2>



Some of the <a href="https://www.earth.com/news/common-plant-can-cause-severe-burns-and-dna-damage/">DNA</a> changes tied to cannabis use were previously linked to conditions like schizophrenia, bipolar disorder, and substance use disorders. While this doesn’t prove a cause-and-effect relationship, it shows a pattern worth paying attention to.



If future research confirms these links, doctors might someday use these markers as early warning signs. They could help flag individuals who may be more vulnerable to certain mental health issues based on their cannabis use history.



<h2 class="wp-block-heading" id="h-marijuana-and-dna-methylation">Marijuana and DNA methylation</h2>



DNA methylation patterns have been linked to a variety of health conditions. Shifting these patterns might change how the body manages cell growth, hormones, and even how it responds to infections.



Scientists have hinted that these modifications could affect neurological processes, too. 



Cannabis has long been studied for its possible connections to mental health, so these DNA changes may be relevant to conditions that involve the brain.



<h2 class="wp-block-heading" id="h-cautious-interpretation">Cautious interpretation</h2>



“This research has provided novel insights into the association between marijuana use and epigenetic factors,” said epidemiologist Drew Nannini from Northwestern University. 



Future research may pinpoint which specific traits or disorders, if any, are most influenced by cannabis-linked epigenetic shifts.



Experts also note that the study relied on self-reported cannabis use. Some participants might have been reluctant to share full details, although confidentiality was maintained to encourage honest responses.



<h2 class="wp-block-heading" id="h-marijuana-use-and-dna-changes">Marijuana use and DNA changes</h2>



A substantial segment of U.S. adults, <a href="https://library.samhsa.gov/product/results-2019-national-survey-drug-use-and-health-nsduh-key-substance-use-and-mental-health" target="_blank" rel="noreferrer noopener">around 49 percent</a>, try marijuana at least once. For frequent or daily users, scientists are interested in whether these epigenetic signs might grow more pronounced over time.



Observing blood samples taken years apart gave the team a way to compare recent users and those who had used cannabis longer. By tracking the same people, they could see how DNA methylation changed along with reported usage levels.



<h2 class="wp-block-heading" id="h-different-effects-over-time">Different effects over time</h2>



The number of methylation markers linked to cannabis changed between the two sample points. At year 15, the team found 53 associated markers, while at year 20, that number jumped to 148.



This suggests that some of the epigenetic effects may accumulate with continued use or become more detectable with age. It also opens the possibility that long-term cannabis exposure may affect the body differently than short-term use.



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



Some experts suggest that more research in different groups is needed to see if these associations appear consistently. 



Larger investigations could help determine whether these epigenetic changes are reversible if someone reduces or stops using marijuana.



Many scientists want to see if these markers correlate with specific outcomes, such as mental health shifts or immune function. It may take time to unravel whether the observed epigenetic changes translate into noticeable health effects.



The study is published in the journal <a href="https://www.nature.com/articles/s41380-023-02106-y" target="_blank" rel="noreferrer noopener">Molecular Psychiatry</a>.

20-year study of 1,000 adults reveals how marijuana alters DNA

Marijuana has intrigued people for decades, especially as more places...

The icy fringe of our planet is sprouting new growth. Fast warming in the Arctic - now running at roughly four times the global average - is reshaping tundra landscapes and affecting shrubs and meadows that have looked the same since the last ice age.



A vast forty‑year experiment, spread across more than 2,000 research plots, shows that almost every facet of Arctic plant life is in flux. Scientists say the changes are an early sign that the wider <a href="https://www.earth.com/news/arctic-fjords-show-signs-of-struggle-in-a-warming-world/" target="_blank" rel="noreferrer noopener">Arctic</a> system, from wildlife to water supplies, will also shift.



<h2 class="wp-block-heading" id="h-summers-lengthen-arctic-shrubs-thrive">Summers lengthen, Arctic shrubs thrive</h2>



Researchers have spent decades tracking the low carpets of <a href="https://www.earth.com/news/planting-moss-helps-restore-land-damaged-by-oil-and-gas-exploration/" target="_blank" rel="noreferrer noopener">mosses</a>, grasses, and dwarf shrubs that dominate mountains and polar plains. They found that almost six in ten plots have already lost some long‑standing species or gained new arrivals.



No single winner or loser stands out everywhere. Local soil moisture, shelter from wind, and the number of frost‑free days all tip the balance in different directions. Yet the pattern is unmistakable: taller, woodier <a href="https://www.earth.com/news/shrubs-play-a-dual-role-in-forest-recovery-following-wildfires/" target="_blank" rel="noreferrer noopener">shrubs</a> thrive when summers lengthen, shading out species that hug the ground.



“Changes in vegetation are an early warning signal that the entire ecosystem will change, with consequential effects on wildlife, humanity, and Earth's natural ability to store <a href="https://www.earth.com/news/carbon-storage-mystery-emerges-in-the-southern-ocean/" target="_blank" rel="noreferrer noopener">carbon</a>,” said co-author Anne Bjorkman, a researcher in plant ecology at the <a href="https://www.gu.se/en" target="_blank" rel="noreferrer noopener">University of Gothenburg</a>.



<h2 class="wp-block-heading" id="h-shrubs-stretch-higher-meadows-shrink"><a></a>Shrubs stretch higher, meadows shrink</h2>



Investigators see the biggest gains among evergreen stragglers such as lingonberry and crowberry, along with fast‑growing willow bushes that keep their leaves only for the warm season. These plants once clung to the Arctic <a href="https://www.earth.com/news/warming-climate-turns-tundra-from-carbon-sink-to-source/" target="_blank" rel="noreferrer noopener">tundra</a> only where snow melted early.



Now they push onto windswept ridges because snow lies for fewer days each year. Where they thicken, their leaves intercept sunlight that formerly bounced off pale lichens or was absorbed by low moss mats. Tall stems also sling snow into drifts that insulate soils, letting roots stay active later in autumn.



“The change in what grows on a site is extensive, with new species appearing and/or existing species disappearing on almost 60% of the experimental plots. There are many factors that determine how plant life changes at a particular Arctic site, such as how wet the soil is, or how windy it is. This affects the microclimate that plants experience,” said Robert Bjork, a researcher at the University of Gothenburg.



“In general, we see that shrubs benefit from a longer growing season, they simply steal the sunlight from species with a low growth habit.”



<h2 class="wp-block-heading" id="h-impacts-of-arctic-shrubs">Impacts of Arctic shrubs </h2>



On open ridges where dwarf birch and willow take hold, <a href="https://www.earth.com/news/how-plant-diversity-can-help-combat-climate-change/" target="_blank" rel="noreferrer noopener">plant diversity</a> often drops. The low‑lying herbs and sedges that fuel summer pollinators can no longer compete.



South of the tree line, mountain birch saplings work upslope, nibbling away at alpine meadows soaked in brief bursts of meltwater. Once those meadows vanish, the displaced flora has no colder niche to retreat to.



“But where the shrubs take over, biodiversity will decrease, and then the question is where the outcompeted species will go. There are no colder regions than the Arctic, and some species may disappear completely from large areas,” Bjorkman said.



Shrub lines affect more than flowers. Dark leaves absorb solar energy, warming surface layers and melting permafrost ice that holds ancient carbon. 



When that carbon leaks as methane or carbon dioxide, regional warming accelerates. Taller plants also trap snow that would otherwise reflect sunlight and delay spring thaw, another feedback that adds heat.



<h2 class="wp-block-heading" id="h-ripples-through-animals-people-and-water"><a></a>Ripples through animals, people, and water</h2>



“Changes in vegetation obviously also affect <a href="https://www.earth.com/news/forest-biodiversity-benefits-from-large-herbivores-like-elephants-and-moose/" target="_blank" rel="noreferrer noopener">herbivorous animals</a>. Reindeer husbandry cannot have the same grazing areas in the valleys as today, perhaps they can find new ones on the bare mountains,” Bjork explained.



“Then tourism will be affected when mountain birches and shrubs take over on the mountains and the alpine meadows with beautiful wildflowers disappear. And it will be difficult to get hold of drinkable water when the glaciers and the late snowfields melt away.”



Reindeer and caribou herds already follow thinner green waves in sprinting summers. The loss of valley forage may force animals higher, straining age‑old herding routes. 



Visitors who come for wide carpets of summer color may find thickets instead. Local communities could face water stress as shrinking glaciers feed fewer melt streams during late summer.



<h2 class="wp-block-heading" id="h-radical-changes-ahead">Radical changes ahead</h2>



Scientists at the Latnjajaure field camp near Abisko, Sweden, witness these shifts in real time. Birches creep onto formerly barren slopes. 



Moss mats turn patchy under rising shrubs. Streams surge earlier in spring and dwindle sooner in August. Yet no one can plot the exact timetable for the next leap.



“We are in the midst of climate change and will reach certain thresholds where the flora will change radically, but we don't know when it will happen. Or how it will happen,”  Bjorkman warned.



<h2 class="wp-block-heading" id="h-the-future-of-arctic-shrubs">The future of Arctic shrubs</h2>



More data will refine forecasts, but the direction is set. Open alpine meadows will contract as shrub lands will expand. Carbon and energy flows between ground and sky will alter, pushing feedback loops that amplify <a href="https://www.earth.com/news/frequent-heatwaves-have-become-the-norm-in-the-arctic-ocean/" target="_blank" rel="noreferrer noopener">Arctic heat</a>.



For conservationists, the lesson is urgent: protect refuges where cold‑loving plants might survive and plan for landscapes that will not stay as they were such as the Arctic. For everyone else, the message is simpler.



The quiet creep of shrubs in the far north is one more sign that climate change is coming. It is here, and it is rewriting the map from the top downward.



The study is published in the journal <a href="https://www.nature.com/articles/s41586-025-08946-8" target="_blank" rel="noreferrer noopener">Nature</a>.
