The strange-but-true origin story of the humble potato - Scientists have known that potatoes are most closely related to two groups of plants — the tomatoes and a cluster of three species called Etuberosum. Certain genes suggested that potatoes were more closely related to tomatoes, while other genes gave the impression that potatoes and Etuberosum had the closer relationship. The interbreeding event occurred some 9 million years ago, which happened to be excellent timing for the potato. This is when the Andes were forming and lots of cold and dry high elevation habitat was appearing.

Pompeii’s Secret Second Life Revealed by Latest Archaeological Finds - Shortly after Pompeii was buried in up to 20 feet of ash and pumice, people returned, some to sift opportunistically through the ruble, and others to try and restart their lives as best they could. The redevelopment had Rome’s backing. By the 5th century, life in the ruined city grew even more strained following the structural damage dealt by resurgent seismic activity, including a second eruption of Vesuvius in 472 C.E. Within 150 years, Roman life at Pompeii appears to have ended. This time for good.

Why lung cancer is a 'hidden epidemic' in this part of the world - There are almost no nerve endings in the lungs, so in the early stages, the most common symptom of lung cancer is no symptom at all. And when symptoms do appear, they are often quite generic — chest pain, coughing up blood, and difficulty breathing. So, doctors in sub-Saharan Africa often misdiagnose lung cancer patients as having tuberculosis, given the high burden in the region. Patients would go through the whole treatment regimen for tuberculosis and not really be investigated for lung cancer. Those lost six to nine months of possible treatment can be deadly, since 55% of people with lung cancer die within a year.

Should we all be taking vitamin supplements? - Evidence is starting to grow that popping a daily multivitamin could be beneficial for health, particularly for older adults. "Mega-dosing", or taking quantities of vitamins higher than the recommended daily allowance, is not recommended.

The Amazon Rainforest Approaches a Point of No Return - Under increasing threats from rampant deforestation and climate change, portions of the Amazon now emit more carbon to the atmosphere than they absorb. The southern Amazon has become hotter and drier, with less soil moisture, lowered water tables, and a higher-than-normal rate of tree mortality. Scientists now believe the Amazon could reach its tipping point — when it loses its natural ability to regenerate and will become permanently degraded — as soon as 2050. The impacts will reverberate globally.

The Many Types of Fluids That Flow in Yellowstone - Yellowstone is no doubt one of the most dynamic places on Earth. The many types of fluids that flow between the mantle and the atmosphere generate explosive volcanic and geyser eruptions, create lava flows, bubbling mud pots, and very rare sulfur flows, and they span nearly the full range of possible material viscosities.

New, Implanted Device Could Offer a Long-Elusive, Drug-Free Treatment for Rheumatoid Arthritis - In late July, the United States Food and Drug Administration approved an implant that uses electrical signals to control inflammation by tapping into the vagus nerve—a pair of nerves that connect the brain with important internal organs. The move marks the first time an electrical therapy has been approved for the treatment of any autoimmune disease.

Midwestern butterfly count: Big data yields bad news and clues – A study of 4.3 million observations in the U.S. Midwest from 1992–2023 to characterize changes in butterfly biodiversity. The results: 59 of the 136 species declined in abundance over the study. Both common and rare butterflies are waning.

104 Grams of Protein For $1.50? - How much ribeye steak is needed to reach 104 grams of protein? It would be about 19 ounces of ribeye steak, which costs $12–20 per pound, and premium cuts can cost more. The ribeye would cost about $14 on the low end or a bit over $20 on the high for the non-premium cuts. The black-eyed peas are only $1.50.

Historic Artifacts from Frank Lloyd Wright’s Only Skyscraper Saved by Conservancy – The Price Tower has been in the news over the past few years…controversy and renovations promised never done. Some objects from the building were sold in a breach of the easement on the building…and now they have been purchased by the Frank Lloyd Wright Conservancy to avoid their being dispersed; the plan is for them to be returned to the building after renovation. The post includes pictures!

Scientists unveil bioplastic that degrades at room temperature, and outperforms petroplastics – Sounds great…but will the existing plastic (made from petroleum) industry let this innovation move forward?

The world is getting hotter – this is what it is doing to our brains - As heatwaves become more intense with climate change, scientists are racing to understand how extreme heat changes the way our brains work. A range of neurological conditions are made worse by rising heat and humidity, including epilepsy, stroke, encephalitis, multiple sclerosis, migraine, along with several others. Heat can also alter other ways our brain functions – making us more violent, grumpy and depressed. Hospital admissions and mortality rates among people with dementia also increase during heatwaves. Rising temperatures have also been linked to an increase in stroke incidents and mortality. And there is a lot we do not know.

Bizarre New Creatures Discovered 30,000 Feet Under the Sea - Entire communities of animals, rooted in organisms that can derive energy not from sunlight but from chemical reactions. Through a process called chemosynthesis, deep-sea microbes can turn compounds like methane and hydrogen sulfide into organic compounds, including sugars, forming the base of the food chain.

Hawaiian Petroglyphs Reemerge for the First Time in Years - The full panel of petroglyphs has been exposed again after seasonal ocean swells swept away covering sand. In all, the petroglyphs are spread across 115 feet of beach and consist of 26 figures and abstract shapes that archaeologists believe were created 500 or more years ago.

The US Commercial Rooftop Solar Market Is About to Explode, Federal Tax Credits or Not - If all goes according to plan, all 500+ projects will be completed during this year into 2026, proving yet again that solar is the fastest way to add more capacity to the nation’s grid. Generating electricity on commercial rooftops and distributing it into the grid is America’s most shovel-ready energy option.

The Power of the Emerald Edge - Whether a tropical forest or coastal temperate rainforest, all forests must contend with a unique set of stressors including changes in land use, invasive insects and disease, and extreme weather events. Rapid changes in climate compound these stressors. How do we prepare our forests for the future? Preserving old-growth forests is one of the most powerful steps we can take.

Elusive and Majestic Red-Crowned Cranes in Hokkaido – Beautiful photographs…of beautiful birds.

Germany’s Stunning Fairytale Castles Added to UNESCO’s World Heritage List - The royal castles of Neuschwanstein, Linderhof, Schachen and Herrenchiemsee have been added to the prestigious list, which includes more than 1,200 sites. Neuschwanstein Castle, located near the village of Schwangau in Bavaria, is one of Germany’s most popular tourist sites. Every year, roughly 1.4 million travelers visit the site.

Learning how to live with shrubbier grasslands (part 1 and part 2) - Our grasslands are getting “shrubbier” and it’s increasingly difficult to prevent that. Because the drivers for that change are mostly beyond our control, it seems obvious that we need to start thinking differently about grassland management.

Introduction of Agriculture Didn't Immediately Alter Japanese Diets - Agriculture, rice, and millet were introduced to the Japanese islands from the Korean Peninsula around 3,000 years ago. Researchers recently examined plant residues on Final Jomon and Yayoi-period pottery from sites in northern Kyushu. The surprising results indicated that local culinary traditions changed very little after the crops were introduced to the island, as fish and seafood remained the primary foods.

Athens Is Reviving a 2,000-Year-Old Roman Aqueduct to Deliver Water to the City Amid Prolonged Droughts - If the Hadrian’s Aqueduct revitalization proves successful, it could become a model for other major cities experiencing water shortages. There are plans to expand in the other boroughs of Athens that the Hadrian Aqueduct runs through. But also, we have started a collaboration with another five or six cities in Europe that combine cultural heritage with water heritage to make more green, sustainable and livable cities.

Photography In the National Parks: Early Summer at White Sands National Park – Some good tips for photography when there is a lot of ‘white’ around! I remember trying in June of 2013 when I visited the place.

Teen bats are spawning new viruses—here’s why scientists are paying close attention - Juvenile bats frequently host multiple coronaviruses simultaneously—offering a real-time window into how new strains might arise. These findings, while involving non-human-infecting viruses, provide a powerful model to forecast how dangerous variants could eventually spill over into humans, especially as environmental pressures bring bats closer to human habitats.

Lentils Have More Protein Than Hamburger? - or a portion size of 100 grams, dry lentils have 23.6 grams of protein, with only 1.92 grams of fat. In case you are wondering, 100 grams is about 3.5 ounces. The amount of protein in “beef, ground, 80% lean meat” is 17.5 grams for the same portion size as the lentils! I’m going to look at some lentil recipes….add them into our meal plans.

A monumental 3,800-year-old warrior kurgan discovered in Azerbaijan - The burial chamber—2 meters wide, 6 meters long, and 3 meters deep—was divided into three symbolic sections: one for the human remains and weaponry, another for ceramic vessels, and a third intentionally left empty, possibly reflecting ritual beliefs about the soul’s journey in the afterlife.

China Breaks Ground on Colossal Dam Project in Asia’s Grand Canyon - A massive dam project in the Yarlung Tsangpo Grand Canyon in Tibet, the longest and deepest canyon in the world. Concerns are being raised about wildlife, electricity it produces being more expensive that comparable solar project, and the Chinese ability to withhold water or flood India in timed of conflict. The article did not discuss if there would be a risk for earthquakes as the weight of the water interacts with the geology of the canyon. Isn’t that area seismically active?

Arizona’s Declining Groundwater - For more than two decades, NASA satellites have peered beneath the surface and measured changes in the groundwater supplies of the Colorado River Basin. Based on these measurements, researchers report rapid and accelerating losses of groundwater in the basin’s underground aquifers between 2002 and 2024. About 68 percent of the losses occurred in the lower part of the basin, which lies mostly in Arizona. Irrigated agriculture consumes about 72 percent of Arizona’s available water supply; cities and industry account for 22 percent and 6 percent.

Mineral v chemical sunscreen: Which one should you be using? - UV exposure can lead to skin cancer, the most common type of cancer in countries including the US and the UK. If it spreads, the deadliest type, melanoma, has only a 35% five-year survival rate. The best sunscreen, experts say, is one you are happy to use!

Meet the Tuatara: New Zealand’s Bizarre Ancient Reptile - While the tuatara is related to snakes and lizards, the two reptilian groups diverged about 250 million years ago. That’s a long time in evolutionary terms. For context, humans are more closely related to kangaroos than tuatara are to lizards.

Greenland Sled Dog DNA Reveals a Story of Human Migration and Ancestry of the Unique Breed - The ancestors of the Inuit arrived in Greenland earlier than previously thought—potentially even before the arrival of the Vikings.

A Bird’s Eye View: Drones Search for Grassland Birds in Colorado - Drones have been used to survey animals from afar for years; this project borrows from those learnings for the novel —and challenging—task of detecting small-bodied, ground-nesting birds (Bobolinks) amid thick, tall grass, without disturbing the species of interest.

Hungary's oldest library is fighting to save 100,000 books from a beetle infestation - Tens of thousands of centuries-old books are being pulled from the shelves of a medieval abbey in Hungary to save them from a beetle infestation that could wipe out centuries of history. I wondered how many of the books have been scanned.

'Wobbly-tooth puberty': How children's brains change at six-years-old – A stage in which a child is constructing their identity, and they're trying to figure out who they are in relation to other people. The transformation includes a greater capacity to reflect on their feelings and modify them when needed, along with an "advanced theory of mind" that allows them to think more sophisticatedly about others' behaviors and respond appropriately. They also begin master the basics of rational enquiry and logical deduction, so that they can take more responsibility for their actions

How a hidden brain circuit fuels fibromyalgia, migraines, and PTSD - Scientists at the Salk Institute have discovered a hidden brain circuit that gives pain its emotional punch—essentially transforming ordinary discomfort into lasting misery. This breakthrough sheds light on why some people suffer more intensely than others from conditions like fibromyalgia, migraines, and PTSD. By identifying the exact group of neurons that link physical pain to emotional suffering, the researchers may have found a new target for treating chronic pain—without relying on addictive medications.

Greenland’s Bejeweled Ice Sheet - In spring 2025, jewel-toned points of blue began to appear on the white surface of the Greenland Ice Sheet. As summer arrived, they grew larger and more numerous, taking on unique shapes and occasionally forming connections. The colorful seasonal phenomenon is due to meltwater from snow and ice, which pools atop the ice sheet in places each melt season. An image from the Operational Land Imager-2 on NASA’s Landsat9.

Easter Island Was Far Less Isolated Than Previously Believed, Study Reveals - Earlier genetic studies in the 2010s laid the ground for the most recent investigation, showing that Easter Island was reached at least two times by the 14th century. Further influence arrived from pre-European South Americans, an interaction evidenced by the presence of sweet potatoes and the Birdman concept. This post is about the idea that after language, plants, animals, and material culture arrived on Easter Island from the west, monumental ritual architecture began traveling in the opposite direction.

In a First, Solar Was Europe’s Biggest Source of Power Last Month - Solar was the largest source of electricity in the EU in June, supplying a record 22 percent of the bloc’s power. Solar amounted to more than 40 percent of generation in the Netherlands and 35 percent in Greece. Analysts say that the June surge in solar power helped Europe weather a brutal heat wave, which saw temperatures soar upwards of 110 degrees F (43 degrees C). Last month was the warmest June on record in Europe, and scientists say that climate change played a key role in the heat wave, pushing temperatures to dangerous extremes.

Inequality has risen from 1970 to Trump − that has 3 hidden costs that undermine democracy – A thought provoking post. The author described 3 ways that the increase in inequality undermines democracy: 1. Fraying social bonds and livelihoods, 2. Increasing corruption in politics, 3. Undermining belief in the common good.

Honeybees remove 80% of pollen—leaving native bees with nothing - Our modern agricultural industry is so reliant on honeybees that humans have introduced them worldwide, and in many cases, they have escaped human management and risen to prominence in natural ecosystems as non-native, feral populations. And, like any other non-native organism, feral honeybees may perturb native ecosystems when they become sufficiently abundant.

Doctors say we’ve been misled about weight and health - Doctors' advice about healthy eating and physical activity is still relevant as it may result in better health. The main goal is to offer good care irrespective of weight, which means not caring less but rather discussing benefits, harms, and what is important to the patient.

Let’s Consider a Couple of Workable Solutions to the Plastic Crisis – The first is to reduce the reliance on plastic shopping bags. Research shows that plastic bags were much less frequently found in beach litter where communities had implemented plastic bag policies. The second is green roofs in cities. Green roofs were shown to be more than capable of intercepting microplastics — at the rate of 97.5% efficiency for trapping microplastics from atmospheric deposition…..and roof areas make up 40-50% of urban impermeable areas.

Melting Glaciers Will Lead to More Volcanic Eruptions – New research from the Chilean Patagonia. Glaciers tend to suppress the volume of eruptions from the volcanoes beneath them. But as glaciers retreat due to climate change, the findings suggest these volcanoes go on to erupt more frequently and more explosively. According to a 2020 study, 245 of the world’s active volcanoes are within three miles of ice. 

A Partnership for a Healthier Appalachian Forest - The story of the southern Appalachians – and many forests across the United States – is one of widespread logging between the early 1900s and 1940s. That was followed by the “Smokey Bear era” of fire suppression. Now active management is the strategy including thinning, herbicide application and controlled burns.

The Vienna cemetery where endangered species and biodiversity thrive – 2.4 sq km (0.9 sq miles). The cemetery is home to European hamsters, Europea green toad, Alpine longhorn beetle, European ground squirrel, and Eurasian hoopee….and many other species.

Florida Seniors Face Rising Homelessness Risk - Florida seniors make up a growing portion of the state’s unhoused population as the housing crisis continues. Cost of housing is increasing with institutional investors buying up land and insurance costs skyrocketing.

Researchers Unearth 3,500-Year Old Peruvian City with an Illustrious History - Probably a market hub, and that once connected Pacific coast communities with those in the Andes and Amazon thriving around the same time as early Middle Eastern and Asian civilizations. The urban center is known as Peñico and was founded between 1,800 and 1,500 B.C., experts said. It is near the location where the Caral civilization, said to be the oldest in the Americas first appeared 5,000 years ago. Following eight years of research, the experts classified as many as 18 structures including ceremonial temples and residential housing complexes. Sculptural reliefs and works showing the pututu, a conch shell trumpet can also be seen on some of the walls. Researchers also found clay sculptures of human and animal figures, as well as necklaces created with beads and seashells.

How Has U.S. Energy Use Changed Since 1776? – Historical perspective. Coal, petroleum and natural gas did not surpass renewables (i.e. wood) until 1885!

Is this the end for Easter Island's moai statues? – The moai are made from tuff, a volcanic rock largely composed of compressed ash. This type of stone is porous and unusually soft. The wind and rain do not treat it kindly. Weathering of the moai appears to have increased sharply during recent decades; drier weather followed by very heavy rains, more wildfires, rising sea level  and increased wave event have all contributed.

The end of tuberculosis that wasn’t - In the late 1980s, many thought the fight against tuberculosis (TB) had been won. A disease that had plagued humans for at least 9000 years was on the path to being eliminated. Three factors raised concerns about the resurgence of tuberculosis in the United States and rich countries in Europe in from mid-1980s and 1990s: HIV/AIDS epidemic, the rise in drug-resistant tuberculosis, and higher rates of TB in foreign-born populations.

The US’s asbestos U-turn: why the Environmental Protection Agency is reconsidering its ban - Each year, around 40,000 deaths in the US and about 5,000 in the UK are attributed to asbestos exposure. If the US ban is lifted, it’s possible that the number in the US could increase over the coming decades while those in the UK will continue to fall. While global consensus moves toward stricter regulation, the US now finds itself at a crossroads, between scientific evidence and pressure from industry.

Inside Egypt’s Enigmatic $1 Billion Grand Museum - During a press conference on June 14, Egyptian Prime Minister Mostafa Madbouly said the official opening was postponed due to “current regional developments”—loosely referring to the then-escalating conflict between Israel and Iran.

Rare, Mind-Bending M.C. Escher Works Are Up for Auction - Escher was a skilled artist who seamlessly bridged the worlds of art, mathematics, and science in the mid-20th century. Today, his influence remains as important as ever, with a fascinating body of work that continues to mesmerize and inspire minds across the world.

As Wind and Solar Grow, China Ships More Coal Overseas - Analysts say the era of “more renewables, more coal” in China is over, with solar and wind now set to displace coal, rather than supplement it. Even under conservative assumptions coal generation in China could soon peak and enter structural decline.

Work, wages and apprenticeships: sifting for clues about the lives of girls in ancient Egypt - Elephantine, a town at Egypt’s southern frontier near modern-day Aswan, provides a unique window into the urban life of some girls who worked in textile workshops during the ancient Egyptian Middle Kingdom, which dates approximately 2030–1650 BCE. Girls received payment for their labor. It also suggests a structured apprenticeship system where young girls (and boys) worked alongside experienced craftswomen. Historians must always look beyond elite contexts to incorporate diverse evidence types – administrative documents, archaeological remains, and artistic representations – to construct a more complete picture of ancient lives.

Earth’s Clouds on the Move - Clouds are common on Earth, but they are ephemeral and challenging to study. Remote sensing has helped scientists tremendously by enabling consistent, global tracking of the elusive features, even over inaccessible areas like the poles and open ocean. Two published studies: 1) Where storm clouds form has changed. The implications for the climate are significant: This has added a large amount of warming to the system. 2) The shift in storm clouds increased the amount of energy absorbed by the oceans by about 0.37 watts per square meter per decade—a substantial amount on a planetary scale. Big question: What has caused the reduction in reflective storm clouds and whether the trend will continue.

Sinkhole Exposes Remnants of Medieval English Hospital - Walls hidden just beneath the city streets that once belonged to the twelfth- or thirteenth-century St. Leonard’s Hospital. The institution was built just after the Norman conquest and replaced the earlier St. Peter’s Hospital, which was founded by the Anglo-Saxon King Aethelstan. It was a place for caring for the unwell, elderly, and the condemned, but also served as an orphanage, helped feed the poor, and provided meals for the prisoners in York Castle. The hospital was destroyed during the Reformation under the reign of Henry VIII.

Lightning Strikes the Arctic: What Will It Mean for the Far North - A warmer world is expected to bring more thunderstorms, especially at higher latitudes. Scientists are now reporting a dramatic surge in lightning in the Far North and are scrambling to parse how this could affect wildfires, the chemistry of the atmosphere, and Arctic ecosystems.

Scavenger Animals Are in Trouble, and That Could Spell Bad News for Human Health - Scavengers are in trouble—and their decline could be harmful to human health. Half of the 17 obligate scavenger species included in the study are considered “vulnerable” or “critically endangered” by the IUCN. When they are reduced in numbers or disappear, some smaller, occasional scavengers are proliferating. These creatures, such as rodents and feral dogs, tend to transmit diseases to humans.

How do sleep trackers work, and are they worth it? A sleep scientist breaks it down - Most modern sleep trackers do a decent job of estimating your total sleep each night. Some are more accurate for sleep staging, but this level of detail isn’t essential for improving the basics of your sleep. Focus on improving your healthy sleep strategies and pay attention to how you feel during the day.

Meet the Kangaroos That Live in Trees - Filling an evolutionary niche akin to monkeys, they’re keystone species in the rainforests of New Guinea and Australia.

Manet Cut This Painting in Half 150 Years Ago. Now, the Two Sides Are Back Together for a Rare Reunion - In 1874, Manet began to paint a scene of the Brasserie Reichshoffen on a large canvas. Unlike his paintings of military scenes or upper-class life of the 1860s, the new piece captured the dramas of everyday life. But Manet became dissatisfied with the composition of the large work and opted to cut the canvas in two. Over the next few years, he refined each half into more concise, if slightly less ambitious, depictions of the same café: At the Café and Corner of a Café-Concert. While both paintings are well regarded, Manet’s contemporaries struggled to understand his decision to separate them. But Manet’s conviction that the two should be kept apart remained strong. When the two paintings of the same café were exhibited at the Triennial Salon in Antwerp in 1879, they were shown in separate rooms.

Deconstructing Buildings: The Quest for New Life for Old Wood - A growing number of cities have launched initiatives to reuse the wood waste from construction and demolition that now ends up in landfills. The challenge, proponents say, is to deploy new techniques for disassembling old buildings and markets for repurposing the salvaged wood. Using reclaimed wood in buildings stores carbon and helps reduce emissions by avoiding the need to cut new trees. Going forward, some architects say, buildings should be designed for disassembly — meaning every structure is built not only to last but also for easy dismantling and repurposing when its time is up.

Why the appendix is much more important than we once thought - The appendix has been shown to be an important component of immune function, especially in early life. In addition, the appendix itself contains a very diverse and varied microbiota distinct from other parts of the gastrointestinal tract, suggesting a specialized role. Removal of the appendix has been associated with a reduction in gut bacterial diversity which can lead to intestinal dysbiosis and potentially increase susceptibility to various diseases. Appendectomy has also been linked to an increase in fungal diversity in the gut; the appendix may play a role in the balance between bacterial and fungal populations, potentially acting as a store of commensal gut microbiota that repopulate the colon after exposure to pathogens or antibiotic treatment. The appendix may play a further role in protecting the gastrointestinal system from invading pathogens.

How Extreme Heat Impacts Children - Infants and young children sweat less and are unable to regulate their core body temperature as well as adults. Playgrounds are not always built with materials designed to withstand heat and prevent burns. Older children such as high school athletes face increased risk of heatstroke and other illnesses during practices and games. 

Weather makers: How microbes living in the clouds affect our lives - Trillions of bacteria, fungi, viruses and single-celled organisms travel the globe high in the atmosphere. Current aerobiologists deploy sophisticated air-samplers on drones and use DNA-sequencing technology to identify airborne life by its genes. The aerobiome, researchers now recognize, is an enormous habitat filled only with visitors. By one estimate about a trillion trillion bacterial cells rise each year from the land and sea into the sky. By another estimate, 50 million tons of fungal spores become airborne in that same time. Untold numbers of viruses, lichen, algae and other microscopic life forms also rise into the air. It's common for them to travel for days before landing, in which time they can soar for hundreds or thousands of miles. The aerobiome is a force to be reckoned with – one that exerts a powerful influence on the chemistry of the atmosphere. It even alters the weather. It turns out that biological molecules and cell walls are exceptionally good at triggering rain. More sobering… In a 2023 survey of clouds, bacteria carrying 29 different kinds of resistance genes were found.  A single airborne bacterium may carry as many as nine resistance genes, each providing a different defense against drugs. Every cubic meter of cloud could hold up to 10,000 resistance genes. A typical cloud floating overhead may hold more than a trillion of them.

The New Normal Is Already a Loss: How Shifting Baselines Skew Our View of Nature - Think back on the bird song you woke up to this morning. You might have pulled out a few recognizable threads, perhaps the robin, the crow, the sparrow. Now imagine what morning might have sounded like to your grandparents. Major scientific studies indicate that it was likely a cacophony of song by comparison—many kinds of birds and more of them. The difference, the shift in normal, is gradual over time and the loss, without memory or data, is hard to define. With each generation, our perception of the natural world changes, and with it, our understanding of what accounts for abundance and loss of biodiversity. A term bandied about is the “new normal.” In ecology, it’s called the shifting baseline syndrome. 

Fungi to the Rescue: How Mushrooms Are Helping Clean Up Toxic Lands - Mycoremediation, the use of fungi to break down pollutants and absorb heavy metals from contaminated soil. Certain species can transform petrochemicals, pesticides, and heavy metals into harmless compounds or concentrate them for safer removal. This nature-based method offers an affordable, less disruptive alternative to traditional “dig and dump” remediation approaches.

The Famous, Feathered Dinosaur Archaeopteryx Could Fly, Suggests New Study of a ‘Beautifully Preserved’ Fossil - A fossil collector discovered the Chicago Archaeopteryx sometime before 1990 in limestone deposits near Solnhofen, Germany, where all known Archaeopteryx fossils originate. As the Field Museum’s preparators worked on the pigeon-sized Chicago Archaeopteryx, they realized that the fossil included more soft tissues and delicate skeletal details than any other known Archaeopteryx specimen. From previous fossils, they already knew the dinosaur had asymmetric feathers, which are vital to creating thrust in modern, flying birds. But the hard slab of limestone around this specimen had also preserved a key layer of feathers called tertials that had never been documented before in Archaeopteryx.

Sequoia And Kings Canyon National Parks' Giant Sequoia Trees - Giant sequoia trees can live to be more than 3,000 years old! Large giant sequoias often owe their size to rapid growth rather than age, so an old giant sequoia will not necessarily be the largest specimen. While these giant trees are more resistant to threats, they are not immune. Climate change influences the growth and survival of sequoias, particularly in the form of droughts with unusually high temperatures known as “hotter droughts.”

5,000-Year-Old Bread Buried in Bronze Age House - The flatbread, which measures, five inches wide and one inch thick, is among the earliest known baked items ever discovered. Analysis determined that it was made from a coarsely ground flour made of emmer, a type of ancient wheat, and lentils. A modern bakery has already begun to reproduce and sell breads based on the ancient recipe.

Tea, berries, dark chocolate and apples could lead to a longer life span - Increasing the diversity of flavonoids within your diet could help prevent the development of health conditions such as type 2 diabetes, cardiovascular disease (CVD), cancer and neurological disease.

Experts Think the Hagia Sophia Is in Danger. They’ve Got a Plan to Protect It from Earthquakes - In light of recent earthquakes in Turkey, experts fear the 1,500-year-old mosque is structurally vulnerable, and the Turkish government has ordered a renovation. A team of government-appointed engineers, architects and art historians will begin by stripping a layer of lead that covers the main dome and looking for ways to strengthen the connections between it and the semi-domes. They’ll also look for ways to improve the main pillars and subterranean supports. Experts are also hoping that the work may reveal older murals from previous periods in the Hagia Sophia’s layered history.

Secrets of the Gobi Wall Revealed - Snaking for 200 miles across the inhospitable terrain of southern Mongolia, the so-called Gobi Wall is the least studied section of a system of medieval fortifications that once extended from China into Mongolia. The wall was primarily constructed from rammed earth, stone, and wood during the Xi Xia period (AD 1038-1227), a dynasty ruled by the Tungut tribes of western China and southern Mongolia. It was much more than a purely defensive mechanism built to repel invasions, but that it also served to regulate trade and manage frontier movements.

Why climbing the stairs can be good for your body and brain - Climbing stairs has been found to improve balance and reduce the risk of falling for older people and improve their lower body strength. Other studies also find that climbing a couple of flights of stairs can positively affect our cognitive abilities such as problem-solving, memory, and potentially creative thinking. As a "low impact" form of exercise, even short bursts of stair climbing can help improve cardiorespiratory fitness and reduce the risk of cardiovascular disease.

When Sears Pioneered Modular Housing - In an early iteration of modular housing, kit homes were sold by companies like Sears and Montgomery Ward in the early and mid-20 century - complete with “all the materials that a kit home purchaser needed to build the home, including at least 10,000 pieces of precut lumber to suit the model of the home, drywall, asphalt roof shingles, carved staircases, and the nails, door knobs, drawer pulls, paint and varnish needed to do the job. Electrical, heating systems, and plumbing materials could also be purchased at extra cost.”

Scientific breakthrough brings CO2 'breathing' batteries closer to reality - Scientists have made a breakthrough in eco-friendly batteries that not only store more energy but could also help tackle greenhouse gas emissions. Lithium-CO2 'breathing' batteries release power while capturing carbon dioxide, offering a greener alternative that may one day outperform today's lithium-ion batteries.

Fitness fight: Native bees struggle against invasive honey bee - High densities of European honey bees could be harming Australian native bees' 'fitness' by reducing their reproductive success and altering key traits linked to survival. Has this happened in North America as well?

Ancient pollen reveals stories about Earth’s history, from the asteroid strike that killed the dinosaurs to the Mayan collapse – Missouri rocks: When an asteroid struck Earth some 66 million years ago, the one blamed for wiping out the dinosaurs, it is believed to have sent a tidal wave crashing onto North America. Marine fossils and rock fragments found in southeastern Missouri appear to have been deposited there by a massive wave generated by the asteroid hitting what is now Mexico’s Yucatan Peninsula. Among the rocks and marine fossils, scientists have found fossilized pollen from the Late Cretaceous and Early Paleocene periods that reflects changes in the surrounding ecosystems. The pollen reveals how ecosystems were instantly disrupted at the time of the asteroid, before gradually rebounding over hundreds to thousands of years.

A New, Shape-Shifting ‘Flapjack’ Octopus Has Been Discovered in the Deep Sea Off the Coast of Australia - The tiny cephalopod grows only about 1.6 inches across, but it can survive more than half a mile beneath the ocean’s surface. During the 2022 expedition, the team used high-tech cameras, nets and sleds to collect samples and snap photographs deep below the ocean’s surface. Many of the specimens they found are thought to be new species.

How the humble chestnut traced the rise and fall of the Roman Empire - According to researchers in Switzerland, the Romans had something of a penchant for sweet chestnut trees, spreading them across Europe. But it wasn't so much the delicate, earthy chestnuts they craved – instead, it was the fast-regrowing timber they prized most, as raw material for their empire's expansion. And this led to them exporting tree cultivation techniques such as coppicing too, which have helped the chestnut flourish across the continent.

China’s Mega Dam Project Poses Big Risks for Asia’s Grand Canyon - China’s plans to build a massive hydro project in Tibet have sparked fears about the environmental impacts on the world’s longest and deepest canyon.

Step Into a Painstakingly Recreated 3D Model of the Parthenon, Now Restored to Its Ancient Glory - By combining archaeology and technology, a researcher has shed light on a longstanding architectural mystery: how the ancient Greeks experienced the inside of the Parthenon, the Athenian Acropolis’ largest temple, built and dedicated to the goddess Athena in the fifth century B.C.E.

How Tikal Became One of the Greatest Mayan Cities—and Then Vanished - Nowadays, the ruins of Tikal, an ancient Maya city in northern Guatemala, have been largely reclaimed by the jungle. Howler monkeys jump from pyramid to pyramid. Bats hide in the crevices of abandoned homes. Bullet ants and tarantulas crawl along the forest floor while coatis—racoon-like animals with long, upright tails—search for fallen fruit. Many of the city’s structures remain unexcavated to ensure their preservation. Tikal began life as a series of small, unassuming hamlets. Across centuries, it grew into one of the largest and mightiest cities in the loosely affiliated network of municipalities that made up the Maya civilization. At its peak, which approximately lasted from 600 to 900 C.E., Tikal comprised an area of roughly 50 square miles, 3,000 stone structures, and a population that may at one point have exceeded 60,000 people. While other Maya settlements like Chichen Itza remained inhabited well into the 12th century C.E., Tikal is thought to have collapsed around the year 900.

Pit Stops on the Monarch Flyway: Arkansas Partnership Benefits Pollinators - You just don’t see as many monarch butterflies as you used to. Researchers have documented that eastern populations of monarchs have declined by as much as 80 percent since the 1990s. A partnership in Arkansas is restoring pollinator habitat, providing those critical stops for butterflies to rest and feed. The habitat is also utilized by migratory songbirds and northern bobwhite, a popular gamebird that has seen significant declines.

Vitamin supplements slow down the progression of glaucoma - In glaucoma, the optic nerve is gradually damaged, leading to vision loss and, in the worst cases, blindness. High pressure in the eye drives the disease, and eye drops, laser treatment or surgery are therefore used to lower the pressure in the eye and thus slow down the disease. n experiments on mice and rats with glaucoma, the researchers gave supplements of the B vitamins B6, B9 and B12, as well as choline. This had a positive effect. A clinical trial has been started to see if the vitamins have the same impact in people.

The surprising power of breathing through your nose – The nose can be the first line of defense for your immune system. Mouth breathing has been shown to increase acidity and dryness in the mouth, linking it to cavities, demineralization of the teeth and gum disease. You can think of the nose like a wind chime for the mind; when air moves through your nose, it seems to have a significant influence on your cognitive processes. Nasal breathing has positive effects on the limbic system – the parts of the brain that regulate emotion and behavior – in ways that mouth breathing doesn't.

Dust in the system -- How Saharan storms threaten Europe's solar power future - New research reveals how Saharan dust impacts solar energy generation in Europe. Dust from North Africa reduces photovoltaic (PV) power output by scattering sunlight, absorbing irradiance, and promoting cloud formation. Based on field data from 46 dust events between 2019 and 2023, the study highlights the difficulty of predicting PV performance during these events.

In Galápagos, Iconic Giant Tortoises Get a Helping Hand - Fifteen species of giant tortoises — the largest in the world — once roamed the Galapagos Islands but today only 11 survive. Dome-shelled tortoises reach sexual maturity at 20 to 25 and lay 16 to 20 eggs at a time. When the park was established in 1959, some of the tortoise species were heading towards extinction while others were deemed vulnerable or threatened. But a captive breeding program launched in 1965 has shown great success and has released more than 10,000 giant tortoises back into the wild.

Walmart Announces Nationwide EV Charging Network - According to a press release from the company, “With a store or club located within 10 miles of approximately 90% of Americans, we are uniquely positioned to deliver a convenient charging option that will help make EV ownership possible whether people live in rural, suburban or urban areas.”

Shingles vaccine lowers the risk of heart disease for up to eight years - There are several reasons why the shingles vaccine may help reduce heart disease. A shingles infection can cause blood vessel damage, inflammation and clot formation that can lead to heart disease. By preventing shingles, vaccination may lower these risks. Our study found stronger benefits in younger people, probably due to a better immune response, and in men, possibly due to differences in vaccine effectiveness. The study was done in South Korea.

Hikers Make Stunning Discovery of $340,000 Gold Hoard in Czech Mountains - Most of the coins are French with the overall hoard broadly dated from 1808 to 1915. There is, however, a notable exception: the Austro-Hungarian coins. Small markings on the coins, known as countermarkings, indicate that they were reissued in 1921 in an area of Yugoslavia most likely encompassing modern-day Serbia and Bosnia and Herzegovina. The hoard remains under investigation and archaeologists hope that with the aid of archival records they will be able to work out the full story behind the treasure.

All of the biggest U.S. cities are sinking - The fastest-sinking city is Houston, with more than 40% of its area subsiding more than 5 millimeters (about 1/5 inch) per year, and 12% sinking at twice that rate. Some localized spots are going down as much as 5 centimeters (2 inches) per year. Two other Texas cities, Fort Worth and Dallas, are not far behind. Some localized fast-sinking zones in other places include areas around New York's LaGuardia Airport, and parts of Las Vegas, Washington, D.C. and San Francisco. Massive ongoing groundwater extraction is the most common cause of these land movements. In Texas, the problem is exacerbated by pumping of oil and gas. Droughts will also likely worsen subsidence in the future. Some buildings in the Miami area are sinking in part due to disruptions in the subsurface caused by construction of newer buildings nearby.

How Herbicide Drift from Farms Is Harming Trees in Midwest - There’s growing evidence that agricultural herbicides — which are also used on golf courses, lawns, and rights of way — are inflicting widespread damage on trees and other vegetation across the Midwest and upper South and perhaps doing broader ecological harm as well. The problem is causing increasing concern and even alarm among landowners, state forestry officials, and scientists. In 48 percent of the cases, researchers found damage more than 1,000 feet from the nearest farm field; six samples showed herbicide damage at more than a mile.

The 11,070-foot (3,374-meter) peak is located within the Tordrillo Mountains, west of Cook Inlet, and is bordered on the south by the Chakachatna River valley and the river’s headwaters, Ch’akajabena Lake. In 2025 gas emissions, earthquakes, and ground deformation in March suggested that an eruption was likely. Several of these indicators lowered slightly in April, reducing the relative likelihood of an eruption.

What Caused the Downfall of Roman Britain? - A team from the University of Cambridge has studied oak-tree rings and found that there were periods of extreme drought in the summers of A.D. 364, 365, and 366. They suggest that these extremely dry conditions affected the Romans’ main crops, spring-sown wheat and barley, and set the stage for the rebellions.

How climate change is supercharging pollen allergies – Longer growing season….and extreme allergy events where trillions of pollen particles, sucked up into the clouds as the storm formed, splintered by rain, lightning and humidity into ever-smaller fragments – then cast back down to Earth for people to breathe them in. In one such event in Australia - emergency rooms saw eight times as many people turning up with breathing problems as they would normally expect. Nearly 10 times as many people with asthma were admitted to hospital. 10 people died. It’s been called ‘thunderstorm asthma.’ In the US, pollen levels are expected to be higher than average in 39 states…with worse symptoms.

Colorful city birds – Brown shades are more common in natural environments than in cities. Successful urban bird species have more elaborate colors in their plumage, which is especially true for females.

Mangrove Pioneers - On the ground, a team surveying tidal marshes near the Florida–Georgia border in 2024 found red mangroves (Rhizophora mangle) and black mangroves (Avicennia germinans) growing 50 miles (80 kilometers) and 14 miles (23 kilometers) farther north, respectively, than their previously documented range. Landsat and other satellite imagery are valuable for monitoring marsh-to-mangrove transitions over larger areas and longer time frames. Conditions along the U.S. East Coast are conducive to mangrove territory expansion - less-frequent extreme cold events and rising winter temperatures in the region as contributing factors to the trees’ survival.

Why Norway is restoring its Cold War military bunkers - Norway is a land with many bunkers. At the peak of the Cold War, the sparsely populated, mountainous country had around 3,000 underground facilities where its armed forces and allies could hide and make life difficult for any invader. Norway is reactivating two of their most iconic underground structures of the Cold War. The role of the reactivated base which has had structural and equipment upgrades is to help the "resilience and survivability" of Norway's F-35s in the face of a Russian attack.

Are Hairstyles the Key to Unlocking Art History’s Most Famous Portraits? - Hairstyling has always been a way that women exacted agency over their self-presentation.  Paintings and sculptures can be rare visual records of these carefully chosen, and ephemeral, hairdos—which, unlike fashion garments, can’t survive and be passed down. (Although some historic wigs and clip-ins have stood the test of time and made it into museum collections.)

Making Sense of Butterfly Declines - Over the past two decades, the total number of butterflies across 554 species has plummeted by 22%. That means a loss of about one butterfly out of every five observed since 2000. This alarming trend underscores the severity of the decline, with many species experiencing drastic reductions in their populations. Three ways to help butterflies: plant native, plant native milkweed (i.e. native host plants), don’t spray.

2,000-Year-Old Wooden Houses Found in China - Houses in Shaoxing, Zhejiang, that date to the Warring States period (475–221 b.c.). The stilted and terraced wood-frame structures would have been covered with reeds and bamboo. The walls, made of interwoven wooden posts and thatch, retain numerous small holes, which archaeologists believe were left by grass ropes used to bind the structure together. Artifacts recovered from the site included primitive porcelain cups, red pottery tripods, ceramic urns, bronze drill bits, and plentiful remains of domestic animals as well as marine resources.

Retreating Arctic Glaciers Have Exposed 1,500 Miles of Coastline - Scientists tracked the movement of 1,500 coastal glaciers from 2000 to 2020, finding that retreating ice had unveiled hundreds of miles of coastline, largely in Greenland - revealing stores of precious metals…. but they warn that newly exposed coastline, which has not been cemented with ice, is vulnerable to erosion and landslides.

Gleanings of the Week Ending April 5, 2025

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

What’s Hiding Inside This 2,200-Year-Old Pyramidal Structure in the Judean Desert? - Alongside Nahal Zohar, a stream in the southern Judean Desert, archaeologists are picking through a large building they believe was used as a stronghold for protecting the caravan route bringing bitumen and salt from the Dead Sea to Mediterranean ports. To date, researchers have found a new Dead Sea Scroll, excellently preserved ancient Roman swords, and a 10,000-year-old basket and lid.

Which Native Plant Are YOU? - Take a moment to enjoy a bit of playful anthropomorphism as you take a Native Plant Personality Quiz, to see which native plant YOU are most like!

Ecologists document Utah's bee species and say beehive state is rich in bee diversity - 1,167 bee species are documented in the state of Utah!

Mud, water and wood: The system that kept a 1604-year-old city afloat - The city, which turned 1604 years old on March 25, is built on the foundations of millions of short wooden piles, pounded in the ground with their tip facing downwards. These trees – larch, oak, alder, pine, spruce and elm of a length ranging between 3.5m (11.5ft) to less than 1m (3ft) – have held up stone palazzos and tall belltowers for centuries, in a true marvel of engineering leveraging the forces of physics and nature.

From Wasteland to Wonder – A free eBook by Basil Camu about trees and how each of us can improve the places we love. It includes QR codes for instructional videos about how to do things. One that I viewed and will apply immediately is how to prune shrubs in a way friendly to the plant…and results in less frequent pruning!

Renewables Accounted for More Than 90 Percent of New Power Globally Last Year - Still, growth is not on pace to meet a global goal to triple renewable capacity by the end of this decade. Continuing its clean-energy dominance, China installed more renewable power than all other countries combined last year.

7 Ways State Wildlife Action Plans Save Species – From the National Wildlife Federation.

Women Played a More Important Role in Producing Medieval Manuscripts Than Previously Thought - Female scribes were responsible for producing at least 110,000 handwritten manuscripts between 400 and 1500 C.E. in the “Latin West,” or the Roman Catholic parts of Europe, researchers find. That represents roughly 1.1 percent of the total 10 million manuscripts produced during that period….and that is likely an underestimate.

Jamestown is Drowning - Millions of artifacts have been excavated from the site over the last century, helping historians to understand much of what we know about this historic early settlement. But untold numbers of other artifacts may soon be lost forever because of increasing water levels, not just from flooding but also from rising groundwater and migrating wetland areas. Among the most profound known impacts are the loss of human remains. The average sea level has risen nearly 1.6 feet in the tidewater region of Virginia—a trend that is now accelerating. Studies predict that about 14 of Historic Jamestown’s 23 acres—or 60 percent—could be permanently underwater within the next 50 years.

These Are the 20 Happiest Countries in the World - The United States dropped to its lowest ranking yet in the annual report. This year, America came in 24th, down from its peak at 11th on the 2012 list.
