Wheat is a major part of our diet, especially in the form of bread. But not all wheat is the same - and the way in which it’s grown, processed, and baked affects the nutrients that are present in it.



Until now, the wheat industry has mostly focused on boosting yields, reducing inputs like fertilizers and pesticides, and ensuring good baking quality. 



What often gets overlooked, however, is that wheat can also be a valuable source of nutrients. In fact, it contributes over 20% to the global supply of fiber, minerals, and trace elements, according to the Food and Agriculture Organization (<a href="https://www.fao.org/home/en" target="_blank" rel="noreferrer noopener">FAO</a>).



But getting more nutrition out of wheat isn’t just about planting a different variety. It involves the entire chain - all the way from the field to the oven.



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



Bread can be surprisingly diverse when it comes to nutrition. A slice of <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5310957/" target="_blank" rel="noreferrer noopener">whole grain bread</a>, for instance, can pack a good amount of fiber, <a href="https://www.earth.com/news/vitamin-b-paradox-supplement-linked-to-heart-disease-risk/">B vitamins</a>, iron, magnesium, and complex carbs. These nutrients help regulate blood sugar, support digestion, and provide long-lasting energy. 



On the flip side, white bread - made from refined flour - loses much of that fiber and many <a href="https://www.earth.com/news/micronutrient-deficiency-rates-are-soaring-worldwide/">micronutrients</a> during processing. Manufacturers often enrich it to add some of those nutrients back, but it still doesn’t match the nutritional punch of whole grain varieties.



The kind of bread you eat matters, but so does how much. Bread is a carb-heavy food, and while carbs aren't the enemy, overdoing them - especially if the bread is low in fiber - can spike your blood sugar and leave you hungrier sooner. 



If you're aiming for a more nutritious option, look for loaves with at least 3 grams of fiber and minimal added sugar. Bonus points for sprouted grains, seeds, or sourdough, which can improve digestion and nutrient absorption.



<h2 class="wp-block-heading" id="h-characteristics-of-wheat-varieties">Characteristics of wheat varieties </h2>



Scientists at the <a href="https://www.uni-hohenheim.de/en" target="_blank" rel="noreferrer noopener">University of Hohenheim</a> and the University Medical Center at the <a href="https://www.uni-mainz.de/en/" target="_blank" rel="noreferrer noopener">University of Mainz</a> teamed up with four wheat breeding companies to study how wheat’s nutritional value can be improved across the whole value chain.



Over five years, they recorded more than 6,000 traits across 282 wheat varieties and 400 breeding lines.



Dr. Friedrich Longin is director of the Wheat Department at the <a href="https://lsa.uni-hohenheim.de/" target="_blank" rel="noreferrer noopener">State Plant Breeding Institute</a> and coordinator of the <a href="https://lsa.uni-hohenheim.de/en/betterwheat_en" target="_blank" rel="noreferrer noopener">Betterwheat project</a>.



“The unique thing about the project was the holistic view of variety characteristics along the entire value chain,” explained Dr. Longin.



“In addition to important characteristics for successful cultivation, several dozen processing characteristics for bakeries were considered, as well as important ingredients and proteins that could be important for <a href="https://www.earth.com/news/proper-nutrition-in-the-first-1000-days-of-life-is-crucial/">human</a> nutrition.”



<h2 class="wp-block-heading" id="h-some-wheat-just-has-more-nutrients">Some wheat just has more nutrients</h2>



The wheat varieties were tested in different environments across Europe to measure how both breeding and growing conditions influence the traits of the wheat.



“This allows us to estimate the extent of the influence of breeding, but also that of the growing environment, on these many traits,” noted Dr. Johannes Schacht, senior wheat breeder at <a href="https://www.limagrain.com/en">Limagrain</a> GmbH.



One of the team's main goals was to understand how nutrient levels vary between wheat types. They tested about 800 wheat samples for 13 key minerals and trace elements like iron and <a href="https://www.earth.com/news/calcium-zinc-are-keys-to-healthier-pregnancy/">zinc</a> - nutrients that are important for immunity, metabolism, and cell health.



“We were able to determine that the nutrient content in different wheat varieties varies greatly - and can fluctuate by up to 50%,” stated Dr. Longin.



“Our trials also show that the nutrients in wheat can be combined well with the required baking qualities in terms of breeding. These correlated positively with the protein content and dough properties.”



<h2 class="wp-block-heading" id="h-measuring-wheat-nutrient-content">Measuring wheat nutrient content</h2>



To apply this research practically, the scientists explored how to quickly measure nutrient content in wheat. 



One method, x-ray fluorescence (XRF) spectrometry, could be a game changer. It scans wheat with X-rays and, based on prior calibrations, provides fast, reliable nutrient readings.



“In order to use this knowledge in practice, xrf fluorescence spectrometry is a method that can be used to measure the nutrient content in wheat quickly and reliably,” explained Dr. Longin.



But using this technology widely would require investment. “This is only possible if the additional work is also paid for,” he added.



And there’s another catch: boosting wheat’s nutrition only makes a difference if people eat more <a href="https://www.earth.com/news/refined-grains-increase-the-risk-of-heart-disease/">whole grains</a> or at least <a href="https://www.earth.com/news/chocolate-with-less-sugar-still-tastes-great-with-a-secret-ingredient/">flours</a> with high type numbers (1050 and up). 



That’s because most nutrients are in the outer layers of the grain, which are lost in refined flours like types 405, 550, and 812.



<h2 class="wp-block-heading" id="h-bakers-make-wheat-digestible">Bakers make wheat digestible</h2>



Even if wheat is nutrient-rich, our bodies might not absorb those nutrients unless the bread is <a href="https://www.earth.com/news/freezing-bread-could-make-it-healthier/">baked</a> the right way.



“The healthy ingredients in wheat are bound in phytic acid. However, this acid cannot be digested and is excreted along with the beneficial nutrients,” said Dr. Longin.



So the researchers partnered with artisan bakers to test four common baking methods. One technique stood out: combining a long dough cycle with sourdough. 



“We found that the phytic acid is almost completely broken down during this baking process, making the ingredients available to the body,” he said.



<h2 class="wp-block-heading" id="h-better-bread-starts-with-better-choices">Better bread starts with better choices</h2>



From field to bakery, everyone involved in wheat production can help improve the nutritional value of bread. But it starts with us.



“All partners in the wheat value chain can influence the nutritional content of bread,” said Dr. Longin. "However, clear priorities must be set: first of all, we consumers should eat more whole grains." 



"This should then be baked with a long leavening process, and only then does breeding and targeted grain trading make sense in order to further optimize the nutrient profile."



Wheat offers more than just <a href="https://www.earth.com/news/eating-almonds-can-help-you-cut-calories/">calories</a>. With the right science, baking methods, and consumer choices, it can play a much bigger role in a healthy diet.

Study reveals how to make wheat bread even healthier while also improving taste

Wheat is a major part of our diet, especially in...

If you've ever forgotten to water your plants for a couple of days, you probably noticed something interesting. The flowers droop quickly. The grass gets dry. But the trees? They’re fine. 



That’s because not all plants handle water the same way. Some use water freely, while others hold back, adjusting to dry conditions in very different ways.



Yet for years, many climate models haven’t taken those differences into account. They’ve relied on simple assumptions that treat every plant alike. That may soon change, thanks to new research that puts plant behavior into the equation.



<h2 class="wp-block-heading" id="h-climate-model-gets-plant-upgrade">Climate model gets plant upgrade</h2>



Scientists from <a href="https://www.ucsb.edu/">UC Santa Barbara</a> and San Diego State University have built a better way to look at how soil dries out after rain. 



Their model shows that plants don’t follow a one-size-fits-all response to water stress. Instead, they behave in complex, adaptive ways - something the researchers say could help sharpen predictions about climate, weather, and water use.



Kelly Caylor, a professor at UCSB’s Bren School of Environmental Science &amp; Management, is the senior author of the study.



“We found that plants don't respond to water stress in a simple, straight-line way,” she said. “Instead, they have dynamic response patterns that reveal whether they're ‘water spenders’ or ‘water savers.’”



<h2 class="wp-block-heading" id="h-where-rainwater-really-goes">Where rainwater really goes</h2>



After it rains, water goes in a few directions. Some of it runs off into rivers. Some seeps down into the ground. 



The rest goes back up into the air - either by evaporating or by moving through plants, which release water through their leaves in a process called transpiration. Together, these are known as <a href="https://www.earth.com/earthpedia-articles/water-cycle/">evapotranspiration</a>.



How quickly soil dries out affects everything from crop growth to wildfire risk to weather forecasts. But until recently, scientists didn’t have good large-scale data on how this drying process worked. Instead, they built models based mostly on rainfall and streamflow.



“Ironically, most models do not use soil moisture data, although the soil moisture is a central component to hydrological behavior,” said lead author Ryoko Araki, a joint doctoral student at UCSB and SDSU.



<h2 class="wp-block-heading" id="h-plants-respond-in-unique-ways">Plants respond in unique ways</h2>



Until now, even the more advanced models made a big assumption: that all plants slow down their water use in the same way, at the same rate, under the same conditions.



“All plants - no matter young or old, summer or winter, tree or grass, small or large,” Araki said. But that assumption skips over a critical part of the picture. Different plants behave differently under <a href="https://www.earth.com/news/plants-have-a-secret-weapon-for-surviving-stress/">stress</a>.



By ignoring that, the models miss out on useful clues. So Araki and her colleagues wondered - could a nonlinear model, one that accounts for more complex plant responses, offer better insights?



<h2 class="wp-block-heading" id="h-a-smarter-way-to-model-moisture">A smarter way to model moisture</h2>



The team began with a standard, linear model based on time and moisture levels. Then they added a nonlinear factor that could reflect how plants adjust their water use as conditions change.



One thing that set this project apart was the data. The scientists used information from NASA’s SMAP satellite, which tracks <a href="https://www.earth.com/news/how-soil-moisture-can-predict-severe-storms/">soil moisture</a> across the globe using microwave sensors. That gave them a way to test their model against real-world conditions.



And it worked. The nonlinear model outperformed the two most widely used linear models. The older models tended to overestimate how fast soil dries out. That can lead to bad predictions—especially in regions where water supply is already tight.



Still, not everyone in the field is on board. Some researchers say the added complexity isn’t worth the trouble.



“Even though the nonlinear model is more complicated, it fits the data better, and it captures more of the system’s behaviors,” Araki said. “It provides a way to investigate <a href="https://www.earth.com/news/how-plants-adapt-to-survive-a-changing-climate/">plant adaptations</a>.”



<h2 class="wp-block-heading" id="h-watching-plants-work-from-space">Watching plants work, from space</h2>



There’s no easy way to track how individual plants manage water stress. You can’t just walk into a forest and see whether a tree is slowing down its water use or pushing forward through dry soil.



“Do they keep growing as much as they can while they still have some amount of water, or do they just completely stop transpiring to prevent tissue damage?” said co-author Bryn Morgan, a former UCSB doctoral student who is now a postdoctoral fellow at MIT.



That’s why this model matters. It gives scientists a window into plant behavior on a massive scale. It also shows that there’s more going on beneath the surface - literally - than many models have accounted for.



For <a href="https://www.earth.com/news/gardeners-can-make-small-changes-to-benefit-pollinators/">gardeners</a>, farmers, and anyone keeping an eye on climate trends, this kind of research could lead to better tools and smarter predictions. Because as it turns out, understanding how a tree survives a dry spell might help all of us prepare for what’s ahead.

Not all plants handle water the same - here’s why it matters

If you've ever forgotten to water your plants for a...

A layer of fossilized resin, known as amber, sits in deep‑sea clay and has puzzled geologists for decades. New fieldwork in northern Japan now shows that a tsunami powerful enough to rip coastal forests from their roots hurled that resin into 11,000‑foot‑deep water during the age of the dinosaurs.



Aya Kubota of the <a href="https://www.gsj.jp/en/" target="_blank" rel="noreferrer noopener">Geological Survey of Japan</a>, and her team, traced the resinous material to a 115‑million‑year‑old horizon in Hokkaido’s Shimonakagawa Quarry, matching it to tsunami‑generated <a href="https://ui.adsabs.harvard.edu/abs/2013AGUFMNH51D..01N/abstract" target="_blank" rel="noreferrer noopener">turbidites</a>.



<h2 class="wp-block-heading" id="h-tracing-the-tree-resin-trail">Tracing the tree resin trail</h2>



Tree resin oozes from bark, traps insects, and usually hardens on a forest floor. Geochemical clocks show that transformation from sticky resin to rock takes at least two million years, yet the Shimonakagawa specimens were still pliable when buried.



Modern tests confirm that resin exposed to air stiffens within about a week, while resin that hits <a href="https://www.pnas.org/doi/10.1073/pnas.0707949104" target="_blank" rel="noreferrer noopener">water</a> can stay soft for much longer. 



That simple fact let the team work backward, proving that the resin reached the seabed almost immediately after leaving the trees.



“As resin exposed to the air hardens quickly in weeks, the flame deformation of the resin suggests that it reached <a href="https://oceanservice.noaa.gov/facts/pelagic.html" target="_blank" rel="noreferrer noopener">pelagic seafloors</a> without significant subaerial exposure,” wrote Kubota and colleagues. 



Those flame structures, familiar to sedimentologists who study load deformities, appear in the amber exactly where dense sand slumped beneath lighter resin.



<h2 class="wp-block-heading" id="h-testing-a-tsunami-hypothesis">Testing a tsunami hypothesis</h2>



<a href="https://www.earth.com/news/90-million-year-old-amber-reveals-antarcticas-secret-past/">Amber</a> occurs in thirty stacked beds within the quarry, some only two inches thick and others nearly nine feet, yet every layer sits above calm‑water clay. 



Storm waves cannot reach such depths, and river floods leave different grain patterns, so the researchers looked to colossal waves.



“Tsunami <a href="https://www.earth.com/news/650-foot-mega-tsunami-sends-seismic-waves-around-world-dickson-fjord-swot-mission/">deposits</a> are rarely recognized in the geological record, except for geologically young Holocene coastal deposits,” the team added. That scarcity makes each confirmed paleotsunami layer a treasure trove for hazard models.



The tallest tsunami measured in modern times reached <a href="https://www.wired.com/2009/07/dayintech-0709" target="_blank" rel="noreferrer noopener">1,720 ft</a> (524 meters) in Alaska’s Lituya Bay in 1958. Even a smaller wave, crossing the ancient Northwest Pacific, could have torn out whole stands of conifer, rafted them far offshore, and dumped their resin as the water retreated.



<h2 class="wp-block-heading" id="h-clues-locked-in-deep-sea-mud">Clues locked in deep‑sea mud</h2>



Besides <a href="https://www.earth.com/news/parasitic-wasp-had-a-flytrap-for-snatching-its-victims/">amber</a>, the Japanese cores contain coffee‑table‑sized rip‑up clasts, broken driftwood more than four feet (1.2 meters) long, and tangled mats of leaves. Each item points to sudden, violent transport from land to abyss rather than slow settling.



Mud cracks on some clasts close upward, showing they dried in air before the wave plucked them from coastal flats. 



Microscopic study reveals intact pollen inside the resin, supporting the idea of a rapid ride that spared delicate grains from decay.



Soft‑sediment folds wrap around still‑elastic resin sheets, confirming that the tsunami‑<a href="https://www.earth.com/news/mega-tsunamis-triggered-by-earthquakes-could-wipe-part-of-us-off-the-map/">triggered</a> slurry flowed over an already mobile seafloor. 



Those folds help explain why the amber sheets resemble squeezed taffy rather than neat droplets.



<h2 class="wp-block-heading" id="h-tsunami-linked-to-massive-landslide">Tsunami linked to massive landslide</h2>



Hokkaido straddles four converging <a href="https://www.earth.com/news/earth-only-has-six-continents-not-seven-tectonic-plates-under-iceland-study/">tectonic plates</a> today, and plate reconstructions indicate a similar geometry in the <a href="https://www.nhm.ac.uk/discover/the-cretaceous-period.html" target="_blank" rel="noreferrer noopener">Early Cretaceous</a>. 



Kubota’s group links the tsunami to a massive landslide that detached a shallow‑marine carbonate platform some 125 miles (200 kilometers) south of the quarry.



Zircon dating of volcanic ash bracketing the amber shows the catastrophe struck between 116.8 million and 114.8 million years ago. 



That window overlaps an interval of heightened plate re‑organization as the <a href="https://www.sciencedirect.com/science/article/pii/S0012821X22000814" target="_blank" rel="noreferrer noopener">Izanagi‑Kula oceanic plate</a> subducted beneath eastern Asia.

Comparable offshore evidence exists elsewhere, including sediment cores that record the 365 CE <a href="https://www.nature.com/articles/s41598-022-09058-3" target="_blank" rel="noreferrer noopener">Crete megatsunami</a> across the Mediterranean basin. 



Those parallels strengthen the idea that deep‑water archives can outlast coastal erosion and preserve tsunami fingerprints for tens of millions of years.



<h2 class="wp-block-heading" id="h-lessons-for-modern-coasts">Lessons for modern coasts</h2>



Today’s engineers map 500‑year floodplains but rarely factor in events of the magnitude inferred at Shimonakagawa. 



Kubota’s discovery shows that extreme waves can move entire forests and carve fresh sediment routes to the deep ocean.



By recognizing amber as a tsunami <a href="https://www.earth.com/news/scientists-detect-a-rare-slow-motion-earthquake-along-japans-tsunami-fault/">tracer</a>, scientists gain a fresh tool for spotting ancient coastal disasters on continental margins worldwide. 



Each new data point refines recurrence estimates and could, eventually, guide zoning in quake‑prone regions.



Forest‑derived carbon delivered to the abyss also hints at hidden climate feedbacks, because buried wood removes atmospheric CO₂ for geologic time. 



Understanding that sink requires knowing how often tsunamis act as high‑speed conveyors from land to sea.



Researchers now plan to scan other Cretaceous drill cores for thin orange films that might mark overlooked tsunami horizons. Success could turn a onetime curiosity into a standard indicator for ancient coastal risk.



Full details of the study are published in the journal <a href="https://www.nature.com/articles/s41598-025-96498-2" target="_blank" rel="noreferrer noopener">Nature</a>.

Massive tsunami swept tree resin and amber from an inland forest out into the seabed

A layer of fossilized resin, known as amber, sits in...

A broad survey of Colorado dispensaries found that nearly half of all cannabis flower products are mislabeled. The THC potency listed on the package often doesn’t match what’s actually inside.



Most of the inaccurate labels overstate the amount of THC - the psychoactive compound in <a href="https://www.earth.com/news/cannabis-extract-cbd-proven-highly-effective-at-killing-mosquitoes/">cannabis</a>. By contrast, testers found that almost all of the concentrates examined - including oils and waxes - were labeled correctly. In fact, 96 percent fell within an acceptable margin of error.



These findings come from the first large-scale audit of potency labels in a legal cannabis market. The researchers provide a rare look at today’s cannabis potency, highlighting where testing is reliable and where it needs improvement.



<h2 class="wp-block-heading" id="h-thc-labels-are-often-inaccurate">THC labels are often inaccurate</h2>



Study senior author Cinnamon Bidwell is an associate professor of psychology and neuroscience at the <a href="https://www.colorado.edu/">University of Colorado Boulder</a> and co-director of the <a href="https://www.colorado.edu/center/cuchange/">Center for Health and Neuroscience, Genes, and Environment</a> (CU Change).



“Cannabis use has complex and wide-ranging effects, and we are working hard to better understand them,” said Bidwell. “While that research plays out, we should, at the very least, be providing accurate information about the amount of THC in these products.”



The <a href="https://www.instituteofcannabisresearchcolorado.org/">Institute of Cannabis Research</a> - Colorado’s official cannabis research institute - funded the project, which researchers carried out with <a href="https://www.medpharm.com/">MedPharm Research, LLC</a>, a licensed testing lab, manufacturer, and retailer.



“We want to instill and foster trust in products, and the only way to do that is to continually evaluate and correct any issues that might be discovered,” said Duncan Mackie, director of pharmacology at MedPharm and a co-author of the paper.



<h2 class="wp-block-heading" id="h-testing-reveals-true-cannabis-potency">Testing reveals true cannabis potency</h2>



Because federal regulations prohibit university scientists from purchasing or handling commercially available cannabis, the team collaborated with MedPharm to collect samples.



A “secret shopper” visited 52 dispensaries across 19 Colorado counties. They purchased 277 products: 178 flower items - including loose buds and pre-rolled joints - and 99 smokable concentrates, ranging from distilled oils to Moroccan hash and waxy “sugar.” Edibles were not part of this phase of the study.



The shopper photographed each label and anonymized every sample with a number. MedPharm chemists, blind to the labeling information, then tested each product.



Flower samples averaged 21 percent THC; concentrates averaged 71 percent, with some as high as 84 percent. For perspective, marijuana in the 1980s typically contained about 8 percent THC.



<h2 class="wp-block-heading" id="h-where-thc-labels-fall-short">Where THC labels fall short</h2>



Colorado considers a cannabis label accurate if the product’s THC content is within 15 percent (higher or lower) of the printed value. Among flower products, 44 percent missed that mark. Of those, 54 items overstated THC levels, while 23 contained more THC than advertised.



Though the average discrepancy was modest - about two percentage points - some errors were large. One sample labeled 24 percent THC, for instance, tested at only 16 percent.



Concentrates fared much better: only four samples fell outside the acceptable range. “When it comes to concentrates, Colorado gets a good grade for labeling accuracy, but there are some real issues with flower,” Bidwell said.



Previous work in other states suggests some third-party testing labs inflate potency results, possibly to satisfy businesses seeking stronger-sounding products.



Yet concentrates, which are homogeneous oils, are easier to measure than the heterogeneous structure of <a href="https://www.earth.com/news/trema-micrantha-brazilian-plant-found-to-contain-cannabis-cbd-compound/%C3%B9">plant</a> material. 



This difference offers another explanation for why flower labels run off-target. Standardizing plant sampling methods could reduce label discrepancies, the authors note.



<h2 class="wp-block-heading" id="h-labels-miss-key-compounds">Labels miss key compounds</h2>



Colorado requires labels to list <a href="https://www.earth.com/news/cbd-reduces-the-unwanted-side-effects-of-thc/">cannabidiol</a> (CBD) content, and 80 to 85 percent of products complied. However, only 16 percent included information on other cannabinoids, such as cannabigerol (CBG) and cannabigerolic acid (CBGA).



Interestingly, the tests found greater quantities of CBG and CBGA - compounds with potential anti-inflammatory and <a href="https://www.earth.com/news/cbd-relieves-anxiety-without-the-risks-that-come-with-thc/">anti-anxiety</a> effects - than CBD across product types. Yet labels rarely show those figures.



“Focusing on THC on the label can actually do a disservice for consumers, because it creates an environment in which people buy based solely on THC content,” Bidwell said. “Our data suggests that multiple other cannabinoids should also be reported there.”



<h2 class="wp-block-heading" id="h-edibles-will-be-examined-next">Edibles will be examined next</h2>



Backed by additional funding from the Institute of Cannabis Research, the team plans to extend its label audit to include edibles and other product categories.



As more states legalize cannabis for medical and recreational use, accurate labeling will become increasingly important for patient safety, informed recreational use, and public trust.



“We all want the same thing: a strong, successful industry that regulators can feel good about, businesses can thrive in, and customers can trust,” Mackie concluded.



The study is published in the journal <a href="https://www.nature.com/articles/s41598-025-03854-3">Scientific Reports</a>.

Many people toast the end of the day with a five‑ounce glass of wine, hoping that ritual keeps heart trouble at bay. Two new analyses suggest the habit might offer real - if limited - protection for adults already at higher risk of cardiovascular disease.



The latest evidence comes from a Spanish arm of the long‑running <a href="https://pubmed.ncbi.nlm.nih.gov/28684083/" target="_blank" rel="noreferrer noopener">PREDIMED trial</a>. The study tracked 1,232 older adults following a <a href="https://my.clevelandclinic.org/health/articles/16037-mediterranean-diet" target="_blank" rel="noreferrer noopener">Mediterranean diet</a> and found that those who averaged roughly half to one glass per day had significantly lower heart risks. 



After five years, their risk of heart attack, stroke, or cardiac death dropped by nearly half.



Researchers verified intake by measuring wine‑derived tartaric acid in urine instead of relying on memory, a switch that turned vague drink logs into hard numbers. 



The work was led by <a href="https://www.clinicbarcelona.org/en/professionals/ramon-estruch" target="_blank" rel="noreferrer noopener">Professor Ramon Estruch</a> of the <a href="https://web.ub.edu/en/" target="_blank" rel="noreferrer noopener">University of Barcelona</a> and <a href="https://www.clinicbarcelona.org/en" target="_blank" rel="noreferrer noopener">Hospital Clinic Barcelona</a>.



<h2 class="wp-block-heading" id="h-chemical-reveals-true-wine-intake">Chemical reveals true wine intake</h2>



Questionnaires often miss what people actually pour, so scientists struggle to pin down alcohol’s true effects. Using the <a href="https://www.mdpi.com/2311-7524/9/11/1173" target="_blank" rel="noreferrer noopener">grape‑exclusive metabolite tartaric acid</a> makes it possible to see how much wine someone enjoyed over the previous week without asking them to confess.



“By measuring tartaric acid in the urine, alongside food and drink questionnaires, we have been able to make a more accurate measurement of wine consumption,” said Estruch.



The study linked tartaric acid levels to self-reported wine intake, confirming it as a reliable consumption marker.



<h2 class="wp-block-heading" id="h-wine-s-effects-in-mediterranean-diets">Wine's effects in Mediterranean diets</h2>



Adopting such objective tools may help resolve decades of conflicting findings that swing from “red wine is medicine” to “no amount is safe.”



The investigators also adjusted for smoking, exercise, and other <a href="https://www.earth.com/news/to-get-fit-and-stay-healthy-walk-this-exact-distance-every-day/">lifestyle habits</a>, so the reduced risk cannot be written off as a simple marker of healthier living.



Importantly, tartaric acid only captures wine, not beer or spirits, letting researchers isolate how fermented <a href="https://www.earth.com/news/hidden-chemistry-of-wine-what-actually-shapes-its-texture/">grape products</a> behave inside a diet already rich in extra‑virgin olive oil, fish, and vegetables.



That context matters because many of wine’s plant compounds appear to interact with the broader Mediterranean plate, enhancing their <a href="https://www.earth.com/news/healing-chronic-wounds-with-gold-and-red-wine/">antioxidant reach</a>.



<h2 class="wp-block-heading" id="h-benefits-tied-to-small-servings">Benefits tied to small servings</h2>



Participants who logged between three and thirty‑five five‑ounce glasses a month, roughly half to one serving a day, saw their risk of a major cardiac event fall by 50 percent. Light users who stayed below half a glass a day gained a 38 percent cut.



Once intake climbed above one glass each day, the advantage disappeared and, in some analyses, reversed. 



That pattern mirrors American Heart Association <a href="https://www.heart.org/en/health-topics/high-blood-pressure/changes-you-can-make-to-manage-high-blood-pressure" target="_blank" rel="noreferrer noopener">guidance</a>, which caps daily wine at one five‑ounce serving for women and two for men.



Men, who made up just under half the study group, appeared to draw a stronger benefit. However, statisticians caution that the sex difference may fade in larger samples.



Even within the favorable range, nurses warned that pouring size matters because many home glasses hold eight or nine ounces, inadvertently nudging people past the safer ceiling.



<h2 class="wp-block-heading" id="h-what-makes-wine-different">What makes wine different</h2>



Wine carries a mix of polyphenols such as resveratrol, quercetin, and catechins that seem to boost the lining of blood vessels. 



Clinical <a href="https://pubmed.ncbi.nlm.nih.gov/34119624/" target="_blank" rel="noreferrer noopener">reviews</a> report that supplemental resveratrol can improve endothelial function, a key factor in healthy blood pressure and clot prevention.



Red wine has more antioxidants due to skin fermentation, though white wine still provides some. That biochemical cocktail may partly explain why studies often find beer or spirits lack the same signal.



Moderate alcohol itself can raise high-density lipoprotein (<a href="https://www.cdc.gov/cholesterol/about/ldl-and-hdl-cholesterol-and-triglycerides.html" target="_blank" rel="noreferrer noopener">HDL</a>), the so‑called “good” cholesterol, yet ethanol also raises triglycerides and blood pressure at larger doses. Polyphenols may tilt the equation back toward benefit, but only within a narrow window.



<h2 class="wp-block-heading" id="h-too-much-wine-harms-the-heart">Too much wine harms the heart</h2>



A 2023 systematic <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2802963" target="_blank" rel="noreferrer noopener">review</a> that pooled data from 4.8 million people found no reduction in all‑cause mortality among moderate drinkers once misclassified former drinkers were excluded. 



The authors warned that earlier optimism probably stemmed from comparing social drinkers with people who quit because of illness.



Heavy pouring is indisputably harmful. Even <a href="https://www.heart.org/en/news/2023/07/31/even-just-1-alcoholic-drink-a-day-may-increase-blood-pressure" target="_blank" rel="noreferrer noopener">one extra daily drink</a> can raise systolic blood pressure by two to four millimeters of mercury, a change large enough to push many people into hypertension. Elevated pressure strains arteries, sets the stage for arrhythmias, and accelerates heart failure.



<a href="https://alcoholresearchforum.org/members/giovanni-de-gaetano/" target="_blank" rel="noreferrer noopener">Professor Giovanni de Gaetano</a> noted that the biomarker approach “provides robust evidence that moderate wine consumption is associated with lower CVD risk. He cautioned that the same data “remind us of the risks associated with higher levels of consumption.”



Alcohol also carries addictive potential, and the Centers for Disease Control and Prevention (CDC) estimates that roughly <a href="https://archive.cdc.gov/www_cdc_gov/media/releases/2014/p0626-excessive-drinking.html" target="_blank" rel="noreferrer noopener">one in ten deaths</a> among working‑age adults is tied to excessive drinking. 



That sobering statistic explains why public health agencies repeat that zero is the only completely risk‑free dose.



<h2 class="wp-block-heading" id="h-wine-humans-and-heart-health">Wine, humans, and heart health</h2>



For adults older than about 35 who already follow a <a href="https://my.clevelandclinic.org/health/articles/16037-mediterranean-diet" target="_blank" rel="noreferrer noopener">Mediterranean diet</a>, a small glass of wine with supper may fit comfortably into a heart‑conscious lifestyle.



People who are pregnant, taking interacting medications, or battling addiction should not take the PREDIMED results as a green light.



Nutrients that give wine its appeal, <a href="https://www.earth.com/news/moderate-wine-consumption-reduces-cardiovascular-risks/">including resveratrol</a>, also reside in grapes, blueberries, nuts, and olive oil. Anyone who chooses to skip alcohol can still obtain similar antioxidant support without ethanol’s downsides.



Clinicians emphasize that no one should start drinking for health reasons. Instead, the sensible takeaway is that very modest wine, enjoyed with meals and within established limits, is unlikely to harm. It might even help certain high‑risk adults when paired with vegetables, fish, and extra‑virgin olive oil.



The study is published in the <a href="https://academic.oup.com/eurheartj/article/46/2/161/7920812" target="_blank" rel="noreferrer noopener">European Heart Journal</a>.

How a glass of wine a day affects your heart, according to doctors

Many people toast the end of the day with a...

Insects are being harmed by a fungicide sprayed on fruits and vegetables - even at levels that are considered safe. 



A new study from <a href="https://www.mq.edu.au/" target="_blank" rel="noreferrer noopener">Macquarie University</a> reveals that the chemical chlorothalonil, which is used globally to prevent fungal disease, is damaging insect fertility and survival.



<h2 class="wp-block-heading" id="h-testing-the-fungicide-on-fruit-flies">Testing the fungicide on fruit flies</h2>



Researchers at Macquarie’s School of Natural Sciences tested the effects of chlorothalonil on <a href="https://www.earth.com/news/fruit-flies-can-walk-jump-and-dance-using-the-same-motor-neurons/">fruit flies</a>, a common insect model used in labs. Fruit flies are representative of a large number of similar insect species in the wild.



The team used <a href="https://www.earth.com/news/for-the-first-time-scientists-have-genetically-engineered-virgin-births/">Drosophila melanogaster</a>, known as the common fruit fly or vinegar fly. Unlike pests that target crops, these flies feed on rotting fruit. They play an important role in breaking down waste and recycling nutrients on farms and in orchards.



“D. melanogaster is also at the bottom of the food chain, becoming food for a whole lot of other species,” said Ph.D. candidate Darshika Dissawa, lead author of the research paper.



<h2 class="wp-block-heading" id="h-a-surprising-decline-in-insect-fertility">A surprising decline in insect fertility</h2>



The experiment exposed fruit fly larvae to chlorothalonil at levels that match what’s found on real agricultural produce, such as cranberries and wine grapes. What they found shocked the team.



“Even the very lowest concentration has a huge impact on the reproduction of the flies that we tested,” said Dissawa. “This can have a big knock-on population impact over time because it affects both male and female fertility.”



Flies exposed to the chemical showed a 37% drop in egg production at maturity, compared to those that were not exposed.



“We expected the effect to increase far more gradually with higher amounts. But we found that even a very small amount can have a strong negative effect,” noted Professor Fleur Ponton.



<h2 class="wp-block-heading" id="h-fungicide-still-in-use-despite-risks">Fungicide still in use, despite risks</h2>



Chlorothalonil is <a href="https://www.europarl.europa.eu/doceo/document/E-9-2024-000263_EN.html">banned</a> in the European Union. But in Australia, it’s still sprayed widely to stop fungal diseases like <a href="https://www.earth.com/news/disease-attacking-blueberry-plants-is-spreading-around-the-world/">mildew</a> and leaf blight.



Residue from this fungicide has been found in soils and water near farms. On food, the levels can range from almost zero to 460 milligrams per kilogram.



“Chlorothalonil is particularly common in orchards and vineyards, and is often used preventatively when no disease is present,” explained Professor Ponton. 



“People assume <a href="https://www.earth.com/news/wild-birds-are-significantly-threatened-by-vineyard-fungicides/">fungicides</a> like chlorothalonil only impact fungal diseases, but they can have devastating, unintended consequences for other species,” she stated.



<h2 class="wp-block-heading" id="h-fungicide-fuels-insect-decline">Fungicide fuels insect decline </h2>



The study revealed that chlorothalonil exposure during the larval stage caused major reproductive issues in the adult flies.



Female flies were smaller, had fewer egg-producing structures, and laid far fewer eggs. Male flies had lower iron levels, which can interfere with sperm production and other metabolic functions.



The researchers also checked whether the flies were avoiding the contaminated food. They weren’t.



“We didn’t find a significant aversion for food contaminated with chlorothalonil, except when there was a very high concentration of the chemical,” explained Professor Ponton. “This means the impacts are due to chlorothalonil ingestion.”



<h2 class="wp-block-heading" id="h-effects-on-insect-pollinators">Effects on insect pollinators</h2>



In agricultural settings where whole crops are treated with fungicides, insects like flies and bees have no way to avoid the chemicals. This creates a larger problem for <a href="https://www.earth.com/news/parasitic-plant-has-some-unlikely-allies-for-pollination-and-seed-dispersal/">pollination</a>, ecosystem stability, and food production.



“We need <a href="https://www.earth.com/news/some-bees-value-quality-over-quantity-in-flower-selection/">bees</a> and flies and other beneficial insects for pollination, and we think this is an important problem for pollinator populations,” said Professor Ponton. “There is a strong commercial incentive to understand the impact in the field and address the use of this chemical.”



Despite the widespread use of <a href="https://www.publiceye.ch/en/topics/pesticides/chlorothalonil-a-banned-pesticide-exported-from-europe">chlorothalonil</a>, there's a surprising lack of research into how it affects insects. Fewer than 25 scientific studies have examined this - far too few, considering the global decline in insect numbers.



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



The team behind the study says it’s time to rethink how fungicides are used in agriculture. Reducing the frequency of spraying could give insect populations a chance to recover. But that requires more research.



“We need field trials to explore options and develop evidence-based guidelines to consider the knock-on effects of fungicides on beneficial insects,” said Professor Ponton.



Next, the researchers will study whether these reproductive problems are passed on to future generations. 



The team also plans to investigate what happens when insects are exposed to combinations of chemicals - something that’s far more common in real-world farming.



The full study was published in the journal <a href="https://royalsocietypublishing.org/doi/10.1098/rsos.250136" target="_blank" rel="noreferrer noopener">Royal Society Open Science</a>.

How crop protection is fueling the global decline of insects

Insects are being harmed by a fungicide sprayed on fruits...

Some species of fig trees possess an extraordinary ability. They can store calcium carbonate inside their trunks, essentially turning parts of themselves into stone. 



A new study shows that these <a href="https://www.earth.com/news/tropical-tree-deaths-are-increasing-even-in-untouched-forests/">trees</a> absorb carbon dioxide from the air and lock it away as calcium carbonate rocks in the surrounding soil.



This surprising discovery comes from an international team of scientists from Kenya, the U.S., Austria, and Switzerland. The experts presented their research at the <a href="https://conf.goldschmidt.info/goldschmidt/2025/meetingapp.cgi" target="_blank" rel="noreferrer noopener">Goldschmidt Conference</a> in Prague.



<h2 class="wp-block-heading" id="h-how-fig-trees-store-carbon">How fig trees store carbon</h2>



These fig trees, which naturally grow in Kenya, are among the first known fruit-bearing trees to use a process called the oxalate carbonate pathway. This process plays a unique role in how these trees manage carbon from the atmosphere. 



Like most <a href="https://www.earth.com/news/tree-species-face-unprecedented-climate-shifts-across-their-ranges/">trees</a>, they absorb carbon dioxide from the air during photosynthesis. They then convert this carbon dioxide into organic carbon, which helps the trees grow. 



The carbon becomes part of their physical structures, including their leaves, roots, branches, and trunks. This is a common way in which trees capture and store carbon.



However, the trees have an additional, remarkable ability. Besides storing carbon in their leaves and wood, they also produce special crystals made from a compound called calcium oxalate.



Over time, the calcium oxalate crystals break down and change into calcium carbonate. Calcium carbonate is a mineral found in natural substances like chalk, limestone, and seashells. It has the ability to stay locked in the soil for a much longer time than regular organic carbon.



<h2 class="wp-block-heading" id="h-benefits-of-carbon-storage">Benefits of carbon storage</h2>



This process provides two major benefits. First, it keeps carbon locked away in a stable, mineral form, reducing the amount of carbon dioxide that might return to the atmosphere. 



Second, the formation of calcium carbonate raises the pH of the soil, making it less acidic. This change in the soil’s chemistry improves the availability of certain nutrients, making the surrounding environment healthier for plants and soil organisms.



In simple terms, these fig <a href="https://www.earth.com/news/climate-change-is-disrupting-how-amazon-trees-process-sunlight/">trees</a> not only store carbon inside their wood but also help improve the soil while trapping carbon in a long-lasting, stone-like form.



<h2 class="wp-block-heading" id="h-fig-trees-lock-carbon-in-their-trunks">Fig trees lock carbon in their trunks</h2>



The study's findings were presented by Dr. Mike Rowley, a senior lecturer at the <a href="https://www.uzh.ch/en.html" target="_blank" rel="noreferrer noopener">University of Zurich</a>.



“We’ve known about the oxalate carbonate pathway for some time, but its potential for sequestering carbon hasn’t been fully considered," explained Dr. Rowley.



"If we’re planting trees for agroforestry and their ability to store CO2 as organic carbon, while producing food, we could choose trees that provide an additional benefit by sequestering inorganic carbon also, in the form of calcium carbonate."



The researchers studied three types of fig trees in Samburu County, Kenya. They measured how far calcium carbonate forms from the trees and examined the microbial communities involved in this transformation.



<h2 class="wp-block-heading" id="h-carbon-storage-inside-tree-wood">Carbon storage inside tree wood</h2>



The team used advanced techniques at the <a href="https://www-ssrl.slac.stanford.edu/ssrl/web/" target="_blank" rel="noreferrer noopener">Stanford Synchrotron Radiation Lightsource</a>. They discovered calcium carbonate deposits both on the tree bark and deep inside the wood.



Dr. Rowley noted that the calcium carbonate is formed, the soil around the tree becomes more alkaline. 



"The calcium carbonate is formed both on the surface of the tree and within the wood structures, likely as microorganisms decompose crystals on the surface and also, penetrate deeper into the tree," said Dr. Rowley.



"It shows that inorganic carbon is being sequestered more deeply within the wood than we previously realized."



Among the fig trees studied, Ficus wakefieldii showed the highest ability to store carbon in this way. Next, the researchers plan to test its suitability for agroforestry by measuring its water needs, fruit production, and <a href="https://www.earth.com/news/amazon-trees-glow-more-under-stress-but-photosynthesize-less/">carbon</a> storage under varying conditions.



<h2 class="wp-block-heading" id="h-implications-for-other-tree-species">Implications for other tree species </h2>



Previous studies on the oxalate carbonate pathway focused mostly on tropical trees that do not bear fruit. The Iroko tree, or Milicia excelsa, was the first identified species with this pathway. It can store up to one ton of calcium carbonate during its life.



Calcium oxalate, which forms these crystals, is common in many plants. Likewise, the microorganisms that convert it to calcium carbonate live in many soils.



“It’s easier to identify calcium carbonate in drier environments. However, even in wetter environments, the carbon can still be sequestered," noted Dr. Rowley.



"So far, numerous species of tree have been identified which can form calcium carbonate. But we believe there are many more." 



"This means that the oxalate-carbonate pathway could be a significant, underexplored opportunity to help mitigate CO2 emissions as we plant trees for forestry or fruit."

How fig trees turn parts of themselves to stone

Some species of fig trees possess an extraordinary ability. They...

Varicose veins bulge and twist across the calves of up to 30 percent of adults, a reminder that blood sometimes pools instead of flowing home to the heart. When sluggish blood flow lingers, clots can form and, in rare cases, travel to the lungs or brain.



Centuries ago physicians in China brewed teas from <a href="https://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?kempercode=z990" target="_blank" rel="noreferrer noopener">Ginkgo biloba</a> leaves to sharpen memory. Today researchers wonder whether the same ginkgo leaves might support weary leg veins and cut the risk of small, yet dangerous, blood clots.



<h2 class="wp-block-heading" id="h-why-circulation-can-falter">Why circulation can falter</h2>



Blood rising from the feet must fight gravity, and faulty valves can leave veins stretched and valves leaky. The lingering pressure distends vein walls, encourages <a href="https://www.earth.com/news/fasting-helps-the-body-fight-inflammation-and-chronic-diseases/">inflammation</a>, and slows platelet aggregation, the first step toward clotting.



Slow venous return creates the setting for deep‑vein thrombosis as well as the aching, throbbing symptoms many patients feel after a day of standing. 



That overlap has pushed vascular specialists toward plant‑based compounds that might tone the vein wall and limit sticky platelets.



After logging stroke cases at Xuanwu Hospital in Beijing, neurologist <a href="https://www.researchgate.net/scientific-contributions/Xiangqian-Huang-2265510495" target="_blank" rel="noreferrer noopener">Xiangqian Huang</a> of <a href="https://ccmu.cucas.cn/" target="_blank" rel="noreferrer noopener">Capital Medical University</a> began probing ginkgo’s effects on clot behavior in the brain, work that now informs leg‑vein research.



<h2 class="wp-block-heading" id="h-ginkgo-leaves-and-blood-flow">Ginkgo leaves and blood flow</h2>



Ginkgo extract made <a href="https://www.earth.com/news/drinking-from-plastic-bottles-linked-to-high-blood-pressure-and-heart-problems/">blood platelets</a> less sticky when triggered by one type of chemical but didn’t have much effect when triggered by another. 



Dr. Xiangqian Huang and the team also noticed that blood took slightly longer to clot after treatment with the extract.



The leaf contains natural compounds that seem to interact with enzymes responsible for forming clots. 



In a 2025 animal <a href="https://pubmed.ncbi.nlm.nih.gov/40462336/" target="_blank" rel="noreferrer noopener">study</a>, researchers found that ginkgo reduced damage inside blood vessels in rats with clotting problems and slightly increased the time it took for their blood to clot. 



<h2 class="wp-block-heading" id="h-insights-from-a-beijing-stroke-ward">Insights from a Beijing stroke ward</h2>



Huang’s real‑world study followed 99 patients for five days. Among stroke survivors who received ginkgo plus baby <a href="https://www.earth.com/news/daily-aspirin-use-strongly-tied-to-colorectal-cancer-prevention/">aspirin</a>, arachidonic‑acid platelet aggregation fell more than in peers on aspirin alone, while major bleeding did not rise.



Minor nose or gum bleeds surfaced in four of thirty‑three combination patients, a signal that enhanced anticoagulation deserves monitoring. No severe hemorrhages occurred, suggesting short‑term safety when doses stay low.



The design also enrolled participants with internal jugular venous stenosis, a group whose <a href="https://www.earth.com/news/artificial-sweetener-erythritol-sugar-substitute-linked-to-blood-clots-heart-disease/">clots</a> mirror those in leg veins. 



In that arm ginkgo alone curbed blood platelet stickiness within 24 hours, and the effect held steady through day five.



<h2 class="wp-block-heading" id="h-aspirin-ginkgo-and-blood-clots">Aspirin, ginkgo, and blood clots</h2>



A team of <a href="https://pubmed.ncbi.nlm.nih.gov/17982321/" target="_blank" rel="noreferrer noopener">scientists</a> led by <a href="https://med.stanford.edu/profiles/christopher-gardner" target="_blank" rel="noreferrer noopener">Christopher Gardner</a> from <a href="https://med.stanford.edu/" target="_blank" rel="noreferrer noopener">Stanford Department of Medicine</a> examined the potential adverse effects of concomitant aspirin and Ginkgo biloba on blood platelet function after giving the duo to older adults for four weeks. The worry was that the herbs might blunt or boost common drugs. 



Gardner and colleagues detected no dangerous bleeding, yet laboratory tests showed additive platelet inhibition, suggesting that low‑dose pairings could protect high‑risk patients who cannot tolerate stronger pharmaceuticals. 



Doctors, however, should adjust regimens around surgeries or when other blood thinners enter the mix.



Because the leaf targets arachidonic‑acid pathways that aspirin already touches, the partnership makes pharmacologic sense. 



Still, anyone taking nonsteroidal anti‑inflammatory drugs should discuss timing and dosage to avoid stacking identical mechanisms.



<h2 class="wp-block-heading" id="h-helping-legs-feel-lighter">Helping legs feel lighter</h2>



Deep veins are not the only place where endothelial cells detach under strain. 



In a classic double‑blind trial, scientists found that a capsule combining ginkgo, troxerutin, and heptaminol cut circulating endothelial cell counts by 14.5 percent in patients with chronic varicose veins, placebo achieved only 8.4 percent.



<a href="https://www.ncbi.nlm.nih.gov/books/NBK26848/" target="_blank" rel="noreferrer noopener">Endothelial cells</a> are early barometers of vein injury, so their decline hints at real structural healing. 



Participants also reported reduced ankle swelling and night cramps, benefits echoed by later Russian and Italian studies that tracked leg circumference.



Modern <a href="https://journals.sagepub.com/home/phl" target="_blank" rel="noreferrer noopener">phlebology</a> still relies on compression stockings and laser ablation, yet many sufferers ask for gentler first steps. 



A standardized ginkgo formula, already licensed for vascular disorders in parts of Europe, may slot neatly between lifestyle changes and invasive procedures.



<h2 class="wp-block-heading" id="h-blood-clot-prevention-with-ginkgo">Blood clot prevention with ginkgo</h2>



Yang’s rat data showed lighter <a href="https://www.earth.com/news/cause-of-strokes-cervical-artery-dissection-has-increased-400-percent-since-2005/">clots</a>, higher nitric‑oxide levels, and longer clotting times after gavage with 60 milligrams per kilogram of extract. 



Nitric oxide relaxes vessel walls and counters platelet stickiness, aligning with human data from stroke and vein clinics.



<a href="https://pubmed.ncbi.nlm.nih.gov/26030402/" target="_blank" rel="noreferrer noopener">Network‑pharmacology</a> maps place AKT1, ALB, and TNF at the center of ginkgo’s target web. Those same genes regulate inflammation, suggesting that the tree’s reach extends beyond platelets to the very lining of our veins.



Because oxidative stress weakens venous valves, the antioxidant side of the extract warrants equal attention. 



Flavonols scavenge free radicals, potentially slowing the progressive dilation that makes early spider veins blossom into rope‑like cords.



<h2 class="wp-block-heading" id="h-talking-with-your-doctor">Talking with your doctor</h2>



Ginkgo supplements crowd store shelves, yet extracts used in clinical trials are highly standardized. Look for<a href="https://pubmed.ncbi.nlm.nih.gov/12757407/" target="_blank" rel="noreferrer noopener"> EGb 761</a> or products specifying at least 24 percent flavonol glycosides and 6 percent terpene lactones.



Patients on warfarin, <a href="https://www.ahajournals.org/doi/10.1161/JAHA.120.017559" target="_blank" rel="noreferrer noopener">direct oral anticoagulants</a>, or upcoming dental work should alert their clinicians before starting any form of ginkgo. 



Health professionals may stagger doses, check clotting labs, or advise pausing the herb to keep bleeding risk low.



For those with aching calves and a family history of clots, discussing ginkgo as an adjunct to compression or low‑intensity exercise could make sense. 



Evidence remains preliminary, yet the plant’s dual action on platelets and vein walls is steadily moving from bench to bedside.



Future multicenter trials ought to track long‑term safety and measure quality‑of‑life changes such as heaviness, itch, and nightly restlessness. If findings stay positive, an ancient tree might soon earn a modern role in vascular medicine.



The study is published in <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11803947/" target="_blank" rel="noreferrer noopener">Thrombosis Journal</a>.

Leaves from this popular tree may improve circulation and prevent blood clots

Varicose veins bulge and twist across the calves of up...

Forests have always been symbols of resilience and endurance. Towering trees stand tall for centuries, forming ecosystems that nurture countless species. They inspire awe, acting as natural archives of Earth’s long history. Yet, today’s rapidly shifting climate is testing this strength like never before.



Scientists now warn that <a href="https://www.earth.com/news/traditional-forest-farming-is-an-overlooked-climate-solution/">forests</a> might struggle to keep pace with the speed of current climate change. This concern isn’t new, but recent research puts into perspective just how slow forest responses can be.



Long before industrial activities fueled modern warming, forests adapted gradually to changes. Over thousands of years, tree populations shifted according to cooling and warming periods. 



During glacial advances, they migrated southward, following milder climates. When the Earth warmed again, they moved north. This dance of migration was a slow process, unfolding over centuries.



But today, the world faces climate shifts at an alarming rate. Forests are locked in place, unable to shift swiftly enough.



<h2 class="wp-block-heading" id="h-forests-struggle-with-climate-change">Forests struggle with climate change</h2>



<a href="https://www.earth.com/news/creating-forests-cant-realistically-cancel-out-fossil-fuel-emissions/">Trees</a> cannot migrate quickly. They grow slowly, and their seeds disperse over limited distances, despite help from wind and animals. Mature trees may live for hundreds of years, meaning populations shift at a glacial pace.



Current climate change, driven by human activities, is happening faster than many forests can adapt. This creates a worrying gap between the pace of warming and the ability of forests to respond.



A recent study published in the journal Science has brought this issue into sharper focus. Led by David Fastovich, a postdoctoral researcher at <a href="https://www.syracuse.edu" target="_blank" rel="noreferrer noopener">Syracuse University</a>, the study provides concrete evidence of how slowly forests react to climate changes.



Fastovich works in the Paleoclimate Dynamics Lab under Tripti Bhattacharya, the Thonis Family Professor of Paleoclimate Dynamics. Their team examined pollen records from lake sediments, revealing tree population shifts over hundreds of thousands of years.



<h2 class="wp-block-heading" id="h-forests-adjusting-to-climate-shifts">Forests adjusting to climate shifts</h2>



The study focused on mapping the time required for <a href="https://www.earth.com/news/protecting-forests-helps-birds-and-humans-in-many-ways/">forests</a> to adjust to climate shifts. Some of the sediment cores analyzed date back up to 600,000 years, capturing long-term changes in forest composition.



“We’ve known these time lags have existed, but no one could put a firm number on them,” said Fastovich. 



“We can intuit how long a tree lives. We can count the rings on a tree and estimate from there. But now we know that after one to two centuries, very close to how long a tree lives on average, entire forest ecosystems begin to turnover as trees die and are replaced in response to climate.”



The results emphasize the deep disconnect between the rapid pace of modern climate change and the natural rhythms of forest migration and replacement.



<h2 class="wp-block-heading" id="h-revealing-forest-patterns">Revealing forest patterns</h2>



To study these long-term changes, the researchers turned to spectral analysis. This statistical method is common in physics and engineering. It allowed the team to compare the relationship between tree populations and climate shifts across varying time scales, from decades to millennia.



The analysis focused on three key aspects: migration patterns, tree mortality, and disturbances like forest fires. By observing these factors together, the team uncovered how <a href="https://www.earth.com/news/forest-carbon-credits-are-failing-so-what-needs-to-change/">forests</a> change over both short and long timescales.



Spectral analysis provided a way to create a unified view of forest dynamics. This approach helped bridge the gap between different disciplines that study forests.



“This gives us a common language for people who observe forest change, ecologists, paleoecologists and paleobiologists, to talk to one another about those changes no matter if we study forests on annual or millennial timescales,” said Fastovich.



<h2 class="wp-block-heading" id="h-forests-shift-but-bigger-changes-emerge">Forests shift but bigger changes emerge</h2>



The research showed that, over the span of a few years or decades, forests change slowly. Small adjustments occur gradually, often unnoticed in the short term. However, significant changes begin to emerge over longer periods.



After about eight centuries, the study found that forest shifts tend to grow more dramatic. These larger changes often align with natural fluctuations in the planet’s climate.



“With this new technique, we can think about ecological processes on any timescale and how they are connected,” said Fastovich. “We can understand how dispersal and population changes interact and cause a forest to change from decades to centuries, and even longer timescales. That hasn’t been done before.”



This insight shows that while forests may appear stable, they are slowly shifting in response to deeper climate rhythms.



<h2 class="wp-block-heading" id="h-urgent-need-for-human-help">Urgent need for human help</h2>



One of the study’s most important findings points to the need for human intervention. Forests are unlikely to adjust fast enough on their own to survive the rapid pace of modern warming.



One promising approach is assisted migration. This method involves deliberately planting tree species from warmer climates into cooler regions. The goal is to help forests adapt by jumpstarting their natural migration processes.



Fastovich emphasized that this kind of intervention is far from simple. Forest adaptation is a slow, complicated process that demands careful, long-term planning.



“There’s a mismatch between the timescales at which forests naturally change to what’s happening today with climate change,” said Fastovich. 



“Population-level changes aren’t going to be fast enough to keep the forests that we care about around. Assisted migration is one tool of many to keep cherished forests around for longer.”



<h2 class="wp-block-heading" id="h-reminder-of-the-challenges-ahead">Reminder of the challenges ahead</h2>



The research serves as a stark reminder of the challenges ahead. Forests are not static. They are ancient, slow-moving communities shaped by time and climate. While their changes might seem imperceptible over a human lifespan, they remain in constant motion.



Now, humanity must make tough choices. Without careful action, many forests may not survive the speed of climate change. 



The tools we choose, whether assisted migration, conservation efforts, or other interventions, will shape the forests of the future. Their survival depends not only on nature’s resilience but also on human responsibility.



The study is published in the journal <a href="https://www.science.org/doi/10.1126/science.adr6700" target="_blank" rel="noreferrer noopener">Science</a>.

Forests are lagging centuries behind in climate adaptation

Forests have always been symbols of resilience and endurance. Towering...

Vanilla is more than just a kitchen staple. It is the world’s most popular spice after saffron and finds its way into everything from ice creams to perfumes and medicines. 



The allure of vanilla's rich, sweet aroma has made it a global commodity, supporting industries and smallholder farmers alike. Yet, hidden behind its widespread appeal lies a fragile reality deeply linked to climate change.



The commercial vanilla crop, derived from the Vanilla planifolia orchid, faces growing challenges. These include threats from drought, heat, and diseases, all of which are worsening under climate change. 



Vanilla <a href="https://www.earth.com/news/traditional-forest-farming-is-an-overlooked-climate-solution/">farming</a> already depends heavily on labor-intensive hand pollination. Any further strain on the species could threaten not only its cultivation but also the livelihoods of many farming communities.



Wild Vanilla species, scattered across the tropics, may hold the key to preserving this treasured crop. They offer a wealth of genetic diversity that could help strengthen cultivated varieties. However, these wild species now face their own climate-driven crises.



<h2 class="wp-block-heading" id="h-how-climate-affects-vanilla-and-pollinators">How climate affects vanilla and pollinators</h2>



Scientists have long recognized the importance of wild Vanilla <a href="https://www.earth.com/news/feeding-the-world-without-harming-nature-the-complex-balance-of-farming/">species</a> as genetic resources. These species possess traits that could improve drought resistance, heat tolerance, and disease resilience in commercial vanilla. However, their survival is tightly linked to pollinators, mainly bees from the Euglossini tribe.



In the natural world, most Vanilla species depend on animal pollinators for reproduction. These intricate relationships, often involving specialized behaviors and physical compatibility, are highly vulnerable to ecological disruptions.



“Climate change may lead to a reduced habitat overlap between Vanilla orchid species and their pollinators, resulting in plant-pollinator decoupling that negatively affects the survival of wild vanilla populations,” said Dr Charlotte Watteyn, a researcher at KU Leuven and the <a href="https://www.ucr.ac.cr" target="_blank" rel="noreferrer noopener">University of Costa Rica</a>.



<h2 class="wp-block-heading" id="h-habitat-shifts-under-climate-pressure">Habitat shifts under climate pressure</h2>



Dr. Watteyn's team analyzed the habitats of 11 Vanilla species along with seven pollinator species. They examined two future climate scenarios: SSP2.4-5 and SSP3-7.0.



The SSP2.4-5 scenario presents moderate climate <a href="https://www.earth.com/news/eco-friendly-farms-can-succeed-but-they-need-support/">risks</a>, with some progress in climate action. In contrast, SSP3-7.0 signals severe challenges, marked by heavy fossil fuel use and limited global cooperation.



Under both scenarios, some Vanilla species may expand their habitats by as much as 140%. However, other species may lose up to 53% of their suitable habitat.



Pollinators face even greater risks. Their suitable habitats are expected to shrink significantly, with the steepest declines under SSP3-7.0. This sharp drop in pollinator populations threatens the entire pollination process.



“Despite the possible increase in suitable habitat for some Vanilla species, their pollinator-dependency may imperil the survival of natural populations,” said Watteyn.



<h2 class="wp-block-heading" id="h-climate-risks-to-vanilla-pollination">Climate risks to vanilla pollination</h2>



Many Vanilla <a href="https://www.earth.com/news/farming-for-wildlife-how-traditional-practices-can-protect-nature/">species</a> rely on distinct pollination methods. Some provide nectar to attract pollinators, while others use deception. Vanilla pompona employs a combination of floral scents and food mimicry to lure bees.



Pollinators, particularly Euglossini bees, face mounting climate threats. Their habitats are expected to shrink, with smaller bee species showing greater vulnerability than larger ones.



“Vanilla species are known for their specialized relationships with pollinators, hence, they may experience difficulties in replacing pollinators,” explained Watteyn. 



Species like V. planifolia and V. trigonocarpa already have limited overlap with their pollinators. Climate change may worsen this.



<h2 class="wp-block-heading" id="h-conservation-priorities-for-vanilla-survival">Conservation priorities for vanilla survival</h2>



The study identified current and future areas where Vanilla <a href="https://www.earth.com/news/climate-change-will-devastate-global-food-production/">species</a> and pollinators overlap. They also flagged areas needing conservation or assisted migration.



By 2050, protected areas covering Vanilla-pollinator overlap could shrink significantly. For example, protected overlap for V. pompona may fall from 42 to 17 percent.



The researchers highlighted areas for urgent conservation. They suggested combining in situ protection with ex situ measures such as seed banks and botanical gardens.



<h2 class="wp-block-heading" id="h-other-threats-beyond-climate">Other threats beyond climate</h2>



Habitat destruction, illegal harvesting, and ecological disruptions also affect Vanilla survival. Many Vanilla species have specific needs, including partnerships with fungi and animals for seed dispersal and germination.



The researchers emphasized the need for more studies on these relationships. “Collaborative research on the ecology and genetic diversity of wild vanilla across its natural distribution is paramount if we want to take vanilla breeding into the future,” said Professor Adam Karremans.



<h2 class="wp-block-heading" id="h-global-vanilla-trade-needs-protection">Global vanilla trade needs protection</h2>



Vanilla remains a major cash crop with high global demand. It supports smallholder farmers worldwide.



“Like cacao and coffee, vanilla is a global export crop with high international market value. It’s grown to make profit, and is a key driver for rural development, agricultural innovation, and overall welfare,” concluded Dr. Watteyn.



Conserving wild Vanilla species now appears essential not just for ecosystems, but also for global food systems. Protecting these species can help secure vanilla’s future amid climate change.

Climate change is separating wild vanilla from its pollinators

Vanilla is more than just a kitchen staple. It is...

Gin lovers often fuss over tonic brands and garnish choices, yet the real flavor hero hides in the berries of one unassuming shrub. Climate scientists and distillers now warn that the taste of those berries is changing fast.



Juniper, the berry that defines every gin on the shelf, is reacting to wilder weather in ways that could nudge the spirit’s familiar piney snap toward unfamiliar territory. 



Assistant Professor Matthew Pauley and Professor Annie Hill at Heriot‑Watt University’s <a href="https://icbd.site.hw.ac.uk/" target="_blank" rel="noreferrer noopener">International Centre for Brewing and Distilling</a> are <a href="https://jib.cibd.org.uk/index.php/jib/article/view/72" target="_blank" rel="noreferrer noopener">tracking</a> the shift.



<h2 class="wp-block-heading" id="h-changing-junipers-are-shaking-gin">Changing junipers are shaking gin</h2>



Gin must lead with juniper by law, so even tiny tweaks in berry chemistry echo through every pour. 



Gin <a href="https://www.gourmetpro.co/blog/guide-to-uk-spirits-market" target="_blank" rel="noreferrer noopener">sales</a> in Britain still top the spirits chart, although the category’s volume slipped 14 percent in 2023 as shoppers flirted with tequila and<a href="https://www.earth.com/news/drunk-decisions-alcohol-affects-men-and-women-differently/"> no‑alcohol options</a>.



The flavor punch comes from a cocktail of volatile compounds such as α‑pinene and limonene that survive distillation and perfume the glass. 



Pauley’s team showed that a single wet growing season can shave those volatiles by roughly 12 percent, a figure big enough for trained <a href="https://www.earth.com/news/cure-for-alcohol-addiction-was-discovered-by-accident/">tasters</a> to notice.



Craft producers often lean harder on juniper than industrial brands, leaving them more exposed to any drop in aromatic intensity. Many small British distilleries already test-drive each harvest in lab stills to adjust recipes before bottling. 



Long before gin, herbalists prized Juniperus <a href="https://www.wildflower.org/plants/result.php?id_plant=juco6" target="_blank" rel="noreferrer noopener">communis</a> for its resinous oils, which scientists now know defend the plant against pests and drought. Those same oils give a London Dry its brisk bite.



<h2 class="wp-block-heading" id="h-changing-climate-and-volatile-chemistry">Changing climate and volatile chemistry</h2>



Rainfall, temperature swings, and late‑season sunshine all steer the berry’s oil profile. 



During the drenched 2017 harvest, berries required extended drying, which let water‑soluble aromas leach away while hydrophobic terpenes lingered. “The least water‑soluble compounds are most affected by post‑harvest drying,” cautioned Hill.



Drier 2018 conditions flipped the script, delivering fruit with brighter citrus notes and sharper pine. The research team measured the shift using <a href="https://www.tandfonline.com/doi/full/10.1080/11263504.2018.1435577" target="_blank" rel="noreferrer noopener">gas chromatography</a>, a lab workhorse that teases apart dozens of aromatic molecules in a single run. 



Earlier ecological studies in Slovakia found essential‑oil yields in wild juniper ranged from 0.4 to 1.9 percent depending on yearly rainfall and soil chemistry, underscoring how environment shapes flavor.



Berries grown at higher altitudes tend to pack more α‑pinene, adding a cleaner, almost eucalyptus edge, while lowland fruit skews toward earthy myrcene. Such variability gives blenders room to play but also raises the risk of <a href="https://www.earth.com/news/more-americans-now-link-alcohol-consumption-to-cancer/">inconsistency</a>. 



A wet June or a scorching August can therefore make the difference between the crisp gin you remember and a softer, vaguely sweeter edition that feels “off” even if you can’t quite say why.



<h2 class="wp-block-heading" id="h-regional-signatures-across-europe">Regional signatures across Europe</h2>



Wine has <a href="https://www.vivino.com/wine-news/terroir-what-is-it-and-why-is-it-controversial?srsltid=AfmBOoov08N8ND9gMb0hboUBEs6-5hOlYPWFgdvOcJu0LXtU4Of7GZTI" target="_blank" rel="noreferrer noopener">terroir</a>, and juniper is proving it can, too. Pauley’s group surveyed berries from Albania, Bosnia, North Macedonia, Montenegro, Serbia, Kosovo, and Italy, finding each origin stamped its own chemical fingerprint on the fruit. 



Italian berries delivered extra limonene, lending bright zest that lightens classic London Dry builds. Balkan harvests leaned woodier and spicier, traits coveted for barrel‑rested gins.



Distillers historically blended multiple lots to hit their “house style,” but escalating climate volatility threatens that safety net as once‑reliable regions swing between soaked and parched. 



Supply chains complicate matters further: most British brands import dried juniper through a handful of brokers, meaning weather in Kosovo can secretly sway a bottle poured in Kansas City months later.



Monitoring programs like the industry’s annual “big sniff,” where distillers collectively nose the incoming crop, act as early warning systems, yet they rely on human sensory memory and can miss subtle chemical drifts.



<h2 class="wp-block-heading" id="h-gin-production-and-juniper-berries">Gin production and juniper berries</h2>



Consistency sells in a crowded market of more than 80 British gin labels, each fighting for back‑bar real estate. Climate disorder thus morphs from agronomic curiosity into commercial headache.



Lower aroma intensity forces producers to add more berries per batch, driving up raw‑material costs while yields from major Balkan suppliers already tighten. Longer drying times raise energy bills and extend production schedules.



Premium gins may risk reformulation fatigue as loyal drinkers notice <a href="https://www.earth.com/news/even-small-amounts-of-alcohol-increase-cancer-risk/">flavor</a> wobbles. Budget brands, buffered by heavier coriander or citrus loads, might skate by, hinting that juniper‑light “new Western” styles could grow.



Regulators could weigh in if botanical content swings so wide that gin no longer tastes predominantly of juniper, challenging the legal definition set by European law.



Investors tracking spirits portfolios now list climatic resilience alongside brand equity, mindful that juniper grows mainly in semi‑wild stands, not easily replanted plantations.



<h2 class="wp-block-heading" id="h-how-distillers-adjust">How distillers adjust</h2>



Data logging of berry moisture and oil content at the point of purchase can flag risky lots before they enter the still. Simple refractometers and hand‑held spectrometers are already cheap enough for small producers.



“So long as we are vigilant of the changes, and curiously explore different areas for harvesting the dry, piney, signature botanical of choice, your gin and tonic is in safe hands,” Pauley assured. 



Sourcing managers may hedge by contracting farms at multiple latitudes, betting that a stormy Adriatic season might be balanced by a calmer Alpine one. 



Process tweaks help, too. Vacuum distillation captures lighter volatiles at lower temperatures, preserving fragile floral tones lost in traditional pot‑still runs. Cold‑stored berries retain more <a href="https://www.earth.com/news/cannabis-related-anxiety-may-be-reduced-with-citrus-based-oil-d-limonene/">limonene</a>, though refrigeration raises carbon footprints. 



Some innovators explore lab‑grown terpenes to top up lean harvests, yet purists counter that synthetic fixes erode the romance of botanicals hand‑picked on rocky hillsides.



<h2 class="wp-block-heading" id="h-gin-juniper-and-future-climate">Gin, juniper, and future climate</h2>



Most casual sippers will not taste a sudden “wrong” note, but subtle drift might explain why a favorite bottle feels muted in one season and lively in the next. 



Ordering gins by region at a bar can double as a geography lesson, revealing how Italian sunshine or Serbian rainfall sneaks into each pour.



If juniper shortages spike prices, expect more botanical‑forward alternatives and a surge of juniper‑lite pink gins that hide the gap behind berries and rhubarb.
