6 Things You Should Never Wear on a Flight – Most of the suggestions are good for road trips as well.

What Your Last Name Says About Your History – Interesting…a different perspective on names.

Photos of the Week – December 6, 2024 – Winter sunrise/sunset beauty on the prairie.

German Archaeologists Discovered the Iconic Bust of Nefertiti in an Ancient Egyptian Sculptor’s Studio – One of the most famous of ancient Egyptian artifacts…’ownership’ has been questioned from the beginning.

Lifesaver for wild bees: The importance of quarries – Research done in Germany, but Missouri has considerable limestone…perhaps we should be striving to keep quarries open rather than overgrown with woody plants. Many wild bees in Germany and in Missouri nest in the ground and often need open, sunny areas to do so.

Archaeologists discover key tool that helped early Americans survive the ice age - Tiny artifacts unearthed at a Wyoming site where a mammoth was butchered 13,000 years ago are revealing intriguing details about how the earliest Americans survived the last ice age. Archaeologists found 32 needle fragments made from animal bone buried almost 15 feet (nearly 5 meters). Analyzing the bone collagen of the needles revealed they were created from the bones of red foxes, bobcats, mountain lions, lynx, the now-extinct American cheetah, and hares or rabbits!

Here Are 2024’s Best Northern Lights Photographs - From a purple and green sky in Canada's Banff National Park to an unexpected, fiery orange appearance in Namibia, this year's auroras took us by surprise. While called the Northern Lights Photographer of the Year, there are plenty of Southern Lights represented in this year's collection too.

The Arctic Could Have Its First ‘Ice-Free’ Day by as Early as 2027 - The first summer on record in which practically all the sea ice in the Arctic melts could occur much earlier than previously expected. In a new study, scientists warn that the ever-increasing greenhouse emissions may bring us closer to an ice-free Arctic by the end of the decade.

Water Infrastructure, Disasters, Water Scarcity & Security, Potable Water, & Conflict – A post about what happened to Ashville, NC. Water-related disasters currently make up over 90% of all disasters on Earth, with record-breaking floods and droughts making headlines around the world. Over the past ten years, the number of fatalities from these catastrophes has doubled. Climate change, warming surface water temperatures, and more aggressive hurricanes making their way up to some of the planet’s oldest mountains in North Carolina have all contributed to a growing awareness that rising temperatures have disrupted the entire water infrastructure of the Appalachians.

Meet the Mysterious Woman Who Shaped MoMA – A biographical post about Lillie P. Bliss and the creation of the Museum of Modern Art as an exhibition focused on her opens.

How a Soviet swamp rat scheme for Azerbaijan went horribly wrong – Nutria introduced in the 1930s…..destroying every wetland in Azerbaijan today.

Light Pollution May Be Keeping Honey Bees Up at Night - On hot nights honey bees will sleep outside and slept less/more fitfully if there is artificial light…which could undermine the health of the colony.

The next massive volcano eruption will cause climate chaos — and we are unprepared – The history of large eruptions and what we can determine about the aftermath…though provoking on what it would be like if a massive eruption happened in the modern world.

Carbon recycling instead of plastic trash – Using iron electrocatalysis and producing green hydrogen as a biproduct…can be powered by solar panels. I hope this can be commercialized near term. We are overwhelming our world with plastic trash!

CT Scans Unlock Secrets of Mummified Individuals at Field Museum – Respect for the ancient dead…but still studying their bodies.

How do countries measure immigration, and how accurate is this data? - Three types of migrants who don’t have a legal immigration status. First, those who cross borders without the right legal permissions. Second, those who enter a country legally but stay after their visa or permission expires. Third, some migrants have legal permission to stay but work in violation of employment restrictions. Most high-income nations have a small minority of irregular immigrants in their immigrant population; the exception is the United States which estimates 22% of their immigrants are irregular.

Riding The Rails on Amtrak's Cardinal Line Through New River Gorge – Maybe a relaxing way to see the National Park and Preserve…thinking about next fall.

Mother Tiger Teaching Cub How to Fight Wins Nature’s Best Photo Awards – Great pictures….but Patricia Homonylo’s video is the most thought provoking….the one that is a call to action.

Geologists rewrite textbooks with new insights from the bottom of the Grand Canyon - From the Tonto Group's 500-meter-thick strata, we're learning about sea-level rise and the effects of catastrophic tropical storms -- probably more powerful than today's devastating hurricanes -- during a period of very hot temperatures when the Earth was ice-free.

Quantifying How Urban Trees Cool Cities - The authors of a new study estimate that the city of Baltimore could reduce land surface temperatures by 0.23°C if they increased tree canopy by 1%. To achieve 1.5°C of cooling, they would need to increase tree canopy cover by 6.39%.

Drought Expands Across the U.S. – We are finally getting some rain…but we are in the ‘extreme drought’ area of southwestern Missouri; it is going to take a lot to get back to ‘normal.’ On October 29, abnormal dryness and drought affected over 78 percent of the American population—the highest percentage in the U.S. Drought Monitor’s 25-year-long record.

Cholera, Zika and West Nile: The deadly diseases that sweep in after hurricanes – Damage to infrastructure has been the big focus of reporting in the US, but diseases are ramping up.

• Florida health authorities released a warning in early October of a likely spike in Vibrio vulnificus infections, urging residents to avoid wading in floodwaters.  Vibrio vulnificus is a bacteria which can cause the breakdown of skin and soft tissue, sometimes leading to amputations.

• West Nile cases rose in Louisiana and Mississippi following Hurricane Katrina.

• Studies found that flooding in Louisiana following hurricanes Rita and Katrina led to an increase in the airborne fungi Penicillium and Aspergillus, which can cause allergies, respiratory infections and pneumonia.

• Research into the aftermath of hurricanes Maria, Irma and Michael, shows that a significant number of people in Florida developed new chronic health conditions such as asthma and allergies in the six months following the disasters.

Satellite Imagery Shows Breadth of Flooding in Spain - Valencia saw a year’s worth of rainfall in just eight hours, with floods destroying buildings, disrupting trains, and leaving more than 100,000 homes without power.

What animal societies can teach us about aging - Humans are not the only animals to change our social behavior as we age. Red deer may become less sociable as they grow old to reduce the risk of picking up diseases, while older house sparrows seem to have fewer social interactions as their peers die off.

The world’s oldest tree? Genetic analysis traces evolution of iconic Pando forest - By sequencing hundreds of samples from the tree, researchers confirmed that Pando, a quaking aspen tree (Populus tremuloides) in Utah, is between 16,000 and 80,000 years old. Pando consists of some 47,000 stems that cover an area of 42.6 hectares in Utah’s Fishlake National Forest. Because of the way the plant reproduces, this collection of aspens is technically all one tree, supported by a single, vast root system. Pando is triploid, meaning that its cells contain three copies of each chromosome, rather than two. As a result, Pando cannot reproduce sexually and mix its DNA with that of other trees, and instead creates clones of itself.

Have we found all the major Maya cities? Not even close – Using lidar to survey 50 square miles revealed evidence of more than 6,500 pre-Hispanic structures, including a previously unknown large city complete with iconic stone pyramids.

Stunning Shortlisted Photos From the 2024 Close-Up Photographer of the Year Contest – My favorite was “Chicory” for the color…and that I knew what it was!

Low-level lead poisoning is still pervasive in the US and globally - Chronic, low-level lead poisoning is a major risk factor for cardiovascular disease in adults and cognitive deficits in children. Factors such as menopause and hyperthyroidism release lead sequestered in the skeleton, which causes a spike in blood lead concentrations. The solution to protecting people from lead poisoning is to identify and eliminate environmental sources of lead: eliminating lead acid batteries, replacing lead service lines, banning leaded aviation fuel, reducing lead in foods, abating lead paint in older housing, and further reducing lead-contaminated soil and other legacy sources.

Ghost Forests Creep Into North Carolina - Large swaths of cypress and pine forests along the southeast Atlantic coast have died, shed their bark, and become pale, leafless snags that line the waterways like gravestones. In the period before winds topple the snags over and shrubs cover them up, researchers call the eerie ecosystems “ghost forests.” One place that is it happening is Alligator River National Wildlife Refuge…and I realized I have been there! We visited in April of 2015. It was the first place I saw river otters and two vultures (different species) sharing a meal. There probably were bald cypress dying in 2015, but it is even more evident now.

Trees cool better than reflective roofs in vulnerable Houston neighborhoods - Heat islands occur in cities where structures such as buildings and roads absorb the sun's heat more than natural landscapes such as trees and grass. The researchers considered three different heat island mitigation strategies: painting roofs white to increase solar reflectance; planting vegetation on roofs to increase evaporation through the plants; and planting more trees, which increases evaporation and provides shade.

Ten Striking Images from the Bird Photographer of the Year Awards – Great images…and the titles/descriptions add to their impact.

From wastelands to wetlands: The fight to save Sri Lanka's natural flood buffers – Transforming garbage patches into biodiverse wetlands in Colombo. About 15 years ago, these ecosystems were degraded and filled with rubbish. Residents organize weekly collection runs, piling up sorted waste at a small collection unit which the municipality sends off for recycling. School kids volunteer, kayaking through the lake to dig up invasive water hyacinth. Ancient kingdoms thrived in a well-managed wetland system where people used them for transport and to grow food. Today, Colombo is home to four wetland parks and several other recreational spaces linked by wetlands.

Eye on the Fertile Crescent: Life Along the Mideast’s Fabled Rivers - The Tigris and Euphrates, the fabled waterways that pour through the heartlands of Eurasian civilization, through the Fertile Crescent, from their chilly headwaters in the mountains of Turkey through vast watersheds in Syria, Kuwait, and Iran, to finally empty into the Persian Gulf at the sweltering marshland shores of Iraq. A series of pictures along the rivers today.

Deaths From Antibiotic-Resistant Infections Could Reach 39 million by 2050 - In 1990, 1.06 million deaths were attributable to antimicrobial resistance. For kids ages 5 and younger, deaths attributable to antibiotic resistance declined by more than 50 percent between 1990 and 2021, mostly due to vaccination, water and sanitation programs, some treatment programs, and the success of those. For patients ages 70 and older, the number of deaths increased by more than 80 percent during the same period. The team estimates that deaths among children will be cut in half by 2050, but deaths among seniors will double. New superbugs can emerge or disappear at a moment’s notice, and scientists still don’t have a good understanding of what causes these unpredictable swings. We urgently need new strategies to decrease the risk of severe infections through vaccines, new drugs, improved health care, better access to existing antibiotics and guidance on how to use them most effectively

Why Are Black Bears Thriving? - Their adaptability has made them one of the world’s most abundant bear species, and also the one faring the best in an increasingly human-dominated landscape.

These Ancient Egyptian Barracks Paint a Vivid Picture of Military Life During the Reign of Ramses II – Mudbrick rooms… evidence of soldiers’ daily provisions, accessories and toiletries, like ivory applicators for kohl eyeliner, necklaces of carnelian and faience beads shaped like pomegranate blossoms, and scarabs engraved with deities’ names. Weaponry demonstrates the place was well armed and may even have been able to produce some weapons on site.

People aren't volunteering as much these days: What gives? - In recent years, giving back to their community hasn't played as big a role in many Americans' lives. The 2008 recession had the biggest dampening effect on volunteering in areas with the most economic growth and above average income equality. When we talk about economic development for communities, we shouldn't divorce that from the civic development of communities. (I was surprised that the study did not find an impact on volunteering from the COVID-19 pandemic…maybe it is too early to see the impact?)

The Largest Prehistoric Structure South of the Sahara - Long after the Kingdom of Zimbabwe’s demise in the 15th century, Great Zimbabwe’s legacy endures. Shona people conducted rites here through the 19th century, and one of the stolen stone eagles that formerly adorned the city graces Zimbabwe’s flag. There are 10 million Shona people around the world today—and there is much to learn about their Bantu-speaking ancestors, who first settled Great Zimbabwe in the 4th century C.E. They farmed, mined iron, and kept cattle, a culinary staple that also denoted social class.

See an Ancient Egyptian Temple’s Brilliant Colors, Newly Revealed Beneath Layers of Dust and Soot - Restoring parts of the 2,000-year-old Temple of Edfu—and shedding new light on what the richly decorated house of worship looked like in its prime: paint and traces of gold leaf.

Brain vasculature changes important for predicting cognitive impairment - A study showing that several measurements of the brain, including blood flow and the brain's ability to compensate for the lack of it, are better predictors of mild cognitive impairment than risk factors like hypertension and high cholesterol. The researcher and its participants are in Oklahoma.

The ancient practice of 'good fire' is reviving Nebraska's birds, bears and berries - In its original shape, the once wide, but relatively shallow Platte River provided an open space for the (sandhill) cranes to roost, while also keeping an eye on predators. These four-to-five-foot tall birds with wingspans of six-to-seven feet found abundant plants and insects to eat on the Nebraskan prairies. Lightning strikes brought occasional wildfires, which cleared out dead material and refreshed native plant life. Fire suppression is not always a good thing…

Giant Slab of Bog Butter Recovered in Ireland – Nearly 50 pounds! It is being analyzed by the National Museum of Ireland. It would be interesting to know how long it had been in the bog.

How Agroforestry Could Help Revitalize America’s Corn Belt – 8,200 hazelnut saplings growing with flocks of chickens in narrow grass paddocks between the rows of fledgling trees…. By combining food-bearing trees and shrubs with poultry production it is an example of agroforestry — an ancient practice that intertwines annual and perennial agriculture. Other forms include alley cropping, in which annual crops including grains, legumes, and vegetables grow between rows of food-bearing trees, and silvopasture, which features cattle munching grass between the rows. An acre of land under agroforestry can sequester five metric tons of CO2 annually, versus one ton for an acre of corn or soybeans. As the region’s vast corn and soybean operations continue hemorrhaging soil and fouling water and climate change proceeds apace, they may find themselves looking for new directions sooner than later.

Humans Pollute the Environment With 57 Million Tons of Plastic Each Year - Uncollected waste is the biggest source of plastic pollution, with at least 1.2 billion people living without waste collection services forced to ‘self-manage’ waste, often by dumping it on land, in rivers, or burning it in open fires. This “self-managed” plastic waste makes up more than two-thirds of the modeled plastic pollution. The study also calculated the largest contributors to plastic pollution in the world: India is in first place, producing 10.2 million tons a year; Nigeria is in second; Indonesia is in third; and China—which had been ranked in first place according to other models—instead comes in fourth. The U.S. ranks 90th, with more than 52,500 tons of plastic pollution produced annually.

One of world's fastest ocean currents is remarkably stable - There is growing scientific and public interest in the global Atlantic Meridional Overturning Circulation, or AMOC, a three-dimensional system of ocean currents that act as a "conveyer belt" to distribute heat, salt, nutrients, and carbon dioxide across the world's oceans. This study found that Florida Current, the beginning of the Gulf Stream system and a key component of the AMOC, has remained stable for the past four decades. Understanding the state of the Florida Current is very important for developing coastal sea level forecast systems, assessing local weather and ecosystem and societal impacts.

Growth of Solar Continues to Defy Predictions - The world is set to install a third more solar capacity this year than it did in 2023, surpassing forecasts by both industry experts and independent analysts. China is driving the bulk of the growth. Through May, India installed more solar capacity than it did in the whole of last year, and in the U.S., new tax breaks are giving the industry a significant boost. Solar manufacturing has jumped fourfold since the passage of the Inflation Reduction Act in 2022.

Birds Form Surprising Relationships with Other Avian Species During Migration - The researchers found that songbirds tended to show up together rather than avoid each other. American redstarts and magnolia warblers reliably appeared together in the researchers’ nets in spring and fall. The same thing happened with ruby-crowned kinglets and white-throated sparrows. The presence of other birds with similar foraging behavior or similar food preferences may signal to newcomers where the good habitat is, helping them refuel more quickly.

Residents in San Joaquin Valley breathe chemical pesticides - A new study found 22% of adults and 10% of children who participated in an air-quality study in California's San Joaquin Valley were breathing detectable levels of pesticides. Participants in this study served as citizen scientists, going about their normal days while wearing the backpacks to collect the samples.

Creative ways communities are reducing food waste – Returning oyster shells to the water in Alabama, collecting food waste for composting in almond orchards in California, gleaning fruit at the end of the season to supply the needy in New Hampshire-Massachusetts, and using underused land to grow free food in Washington.

Only Two US Metro Areas Are Affordable for Homebuyers - Before the Covid-19 pandemic, 20 U.S. states were considered affordable home-buying markets for most households. Today, just two metro areas remain ‘affordable’ by that definition issued by the National Association of Realtors — and no entire states fit the bill. The two metro areas are Youngstown and Akron, Ohio. Home prices have increased by 47% nationwide just since 2020, according to a June report by the Harvard Joint Center for Housing Studies. A major factor is that there aren’t many homes for sale.

Witness 1.8 billion years of tectonic plates dance across Earth’s surface in a new animation – I watched the video twice…the first just enjoying the overall moves. The second time I watched for how North America moved over time.

What Are the Best Policies for Reducing Carbon Emissions? - A systematic analysis of more than 1,500 climate policies from around the world found that only 63 were successful, reducing average emissions by 19 percent on average. Policies are more effective when implemented with a variety of other policies, instead of alone. In the U.K., banning coal-fired power plants worked when it was combined with tax or price incentives. The same was true for banning combustion engine cars in Norway. The study also found that successful strategies differed between countries—in developed countries, carbon pricing was effective, while regulation was successful in developing countries.

How thyroid hormone fuels the drive to explore - Research in mice sheds light on how thyroid hormone alters wiring in the brain. Findings reveal that thyroid hormone syncs up the brain and body to drive exploratory behavior. Too little thyroid hormone slows down metabolism and can result in symptoms of depression, while too much speeds up metabolism and can lead to symptoms of mania. The receptor for thyroid hormone is expressed by cells throughout the entire brain, including in areas of the cortex responsible for high-level cognition like planning and decision-making.

Cutthroats and Cottonwoods: Protecting the South Fork of the Snake - The South Fork contains the largest cottonwood gallery in the West. In the fall, the leaves on the tall-timbered giants lining the banks bounce in the breeze like gold coins exploding from the pot at rainbow’s end. Native Yellowstone cutthroat trout are in the South Fork. Most of the cutthroats spawn in tributaries contributing to the South Fork but they are found throughout and the farther you float, the bigger they get…. a river that is as it should be. Consistently wild.

Nutrition and healthy aging: The role of protein quality in combatting muscle loss - Aging may reduce our ability to digest, absorb and utilize the nutrients in food. It is important to consider increasing the amount and improving the quality of protein (probably higher than what is currently recommended for the general population) we consume. For example – research showed that consuming higher-quality (whey and pea) protein supplements at breakfast and lunch increased muscle-building in older adults by almost 10 per cent. However, collagen protein — a supplement heavily marketed towards older adults — did nothing to bolster muscle-building in older adults.

Flash Flood Roars Through Frijoles Canyon at Bandelier National Monument – One of my favorite places in New Mexico……hope I can visit again sometime when it isn’t flooded!

Cooler Communities for All - Four key design strategies to reduce urban temperatures:

• Increase tree percentage in parks and green spaces

• Provide shade

• Use plant materials and water instead of hardscape

• Switch to green ground cover, including grasses and shrubs

This Massive Egyptian Observatory Is Unlocking Celestial Secrets of an Ancient Culture - Archaeologists in Egypt have just uncovered a truly stellar find—a sixth century B.C.E. astronomical observatory in the ancient city of Kafr El-Sheikh. The observatory, made from mud bricks, is the largest and oldest of its kind in the region, spanning nearly 10,000 square feet. It was in ancient Egypt that the 365-day calendar was born, and the 24-hour day. They completely mapped the night sky, and had their own constellations and zodiac, some signs of which are still recognized today.

Looting of the Sudan National Museum – more is at stake than priceless ancient treasures - It was founded in 1959, ahead of the construction of the Aswan High Dam. A Unesco-led salvage campaign was launched in 1960 to protect and preserve the ancient monuments that would be flooded by the dam, which would alter the landscape of the Nubian region. The reported loss of parts of this collection represents a profound and multi-layered tragedy for future generations.

The Mysterious Turkish Megaliths That Predate the Pyramids - Göbekli Tepe or “Potbelly Hill” in Turkish…it may be the world’s oldest calendar.

Planes, trains and monster diggers: The vehicles pushing the limits of electric power - BBC Future Planet recently went on a hunt for some of the biggest electric vehicles in the world – by size and weight. There is no shortage of impressive examples, from giant mining machines to trains and cargo ships. Often the largest excavators are connected to an electric power source by a cable, rather than using an on-board battery. But in terms of weight, heavy goods vehicles are among the largest EVs you might find yourself sharing the road with. Volvo's FH Electric truck, if you include its double trailer and load, is among contenders for the heaviest battery-powered electric road vehicle. Though research suggests we might one day see electric passenger aircraft capable of carrying as many as 90 people. The biggest electric planes today can accommodate a maximum of around nine passengers. The most powerful electric train in the world is perhaps the Shen24 in China. It is capable of carrying more than 10,000 tons – of coal – at up to 120km/h (75 mph).

A photographer captures life in America’s last remaining old-growth forests – What a great project photographer David Herasimtschuk had undertaken!

Plankton mark seasons in the sea, just like leaves and flowers on land – The seasonal flux of phytoplankton and zooplankton. The photo of diatoms (algae) in this post was what caught my attention; I’ve always enjoyed finding them in water samples.

14 Extraordinary Highly Commended Photos From the 2024 Wildlife Photographer of the Year Contest – My favorite was “Leaving the Nest” …two tawny owlets.

The Ancient Temple Carved Out of a Single Rock - Kailasa Cave, one of 34 in the Ellora Caves complex that has been cut and dug from the basalt rock of the Deccan plateau. 100 feet high and 300 feet long would make it the world’s largest—with all four sides liberated and sculpted into pavilions, halls, vestibules, towers, and courtyards by 800 hardy monks over 150 years beginning in the 7th century BCE. It was once painted white to mimic the Himalayan peak.

Thracian horseman’s grave unearthed in Bulgaria - The man was buried wearing clothing decorated with gold appliqués. A gold necklace, a gold diadem, a gold ring, and a knife decorated with gold and semiprecious stones were recovered from the burial, in addition to the remains of a horse and full battle gear, including a breastplate, sword, scabbard, and other knives and spears

Microplastics Found in Human Brains - The brains of people who suffered from dementia contained significantly more plastic than the brains of healthy people. Troublingly, the new study found more plastic in brain samples gathered in 2024 than in samples gathered in 2016.

Wildlife Photographer Captures Intimate Photos of Alaska’s Grizzly Bears – The bears of Lake Clark National Park. Wildlife photographers from around the world started coming to the Kenai Peninsula in Lake Clark National Park around 15 years ago, but they can’t get up close to the bears without a trained guide close by.

Solar Energy Revolution Brewing In Arkansas, With An Assist From GM - As of Q1 2024, Arkansas ranked #27 on the state-by-state rankings of installed solar capacity tracked by the Solar Energy Industries Association. One area that has seen some healthy activity is rooftop solar and other small-scale projects. According to the figures kept by SEIA, a single utility-scale solar project in Chicot County accounted for an outsized share of the 1,122 megawatts of installed capacity (140 megawatts). Last week GM announced that it has entered a PPA for electricity from the largest ever solar energy project in Arkansas so far, the Newport Solar project. Located in the town of Newport, the 180-megawatt project comes under the umbrella of the firm NorthStar Clean Energy, a branch of CMS Energy.

Say 'aah' and get a diagnosis on the spot: is this the future of health? - Analyzing the color of the human tongue. The proposed imaging system can diagnose diabetes, stroke, anemia, asthma, liver and gallbladder conditions, COVID-19, and a range of vascular and gastrointestinal issues.

The weird way the Los Angeles basin alters earthquakes - The enormous five-mile-deep (8km), sediment-filled basin that LA is built upon plays a surprising role in the effects felt above ground. Imagine the Los Angeles basin as a giant bowl of jelly – the dense rocky mountains and underlying rock make up the bowl, while the sediment fill is represented by the gelatinous mixture. If you shake the bottom [of the bowl] a little bit, the top flops back and forth quite a bit. And atop this quivering mass of jelly is the megacity of Los Angeles. Other cities built on basins: Seattle, Portland, Salt Lake City, Mexico City, and Tehran.

Rethinking the dodo - The Dodo was the first living thing that was recorded as being present and then disappeared. Researchers went through all the literature on the Dodo encompassing hundreds of accounts dating back to 1598 and visited specimens around the UK, including the world's only surviving soft tissue from the Dodo, in the Oxford Museum. They confirm that the bird was a member of the columbid (pigeon and dove) family. Contrary to previous assumptions about its demise, it was almost certainly a very active and fast animal.

Elite Woman’s Grave Found in an Abandoned Fortress in Mongolia - The fortress of Khar Nuur was part of a system of walls and fortresses that spanned nearly 2,500 miles. Radiocarbon dating of the burial indicates that it dates to between A.D. 1158 and 1214, after the fortress had been abandoned, and likely between the fall of the Khitan or Liao Empire in A.D. 1125 and the rise of the Mongolian Empire in A.D. 1206. The researchers explained that the burial is one of only 25 graves dated to this period that have been found in Mongolia. The woman was between the ages of 40 and 60 at the time of death, and she was dressed in a yellow silk robe and headdress made of materials likely imported from China. Her coffin, made of non-local wood, also contained gold earrings, a silver cup, a bronze vessel, a gold bracelet, and coral and glass beads.

The banana apocalypse is near, but biologists might have found a key to their survival - Today, the most popular type of commercially available banana is the Cavendish variety, which was bred as a disease-resistant response to the Gros Michel banana extinction in the 1950s from Fusarium wilt of banana (FWB). For about 40 years, the Cavendish banana thrived across the globe in the vast monocultured plantations that supply the majority of the world's commercial banana crop. In the 1990s, a new strain of the Fusarium fungus started causing problems….and the research race was on to save bananas.

Florida is building the world's largest environmental restoration project - In February 2023, a large digger broke ground on a multi-billion-dollar project that has been decades in the making: building a reservoir the size of Manhattan Island. The reservoir, which is part of an historic restoration of the Everglades ecosystem, is intended to help bring a secure, long-term supply of clean drinking water to Florida's residents. The whole project is due to be completed in 2029.

Streetlights Helping Trees Defend Against Insects - Streetlights left on all night cause leaves to become so tough that insects cannot eat them, threatening the food chain. Decreased herbivory can lead to trophic cascading effects in ecology. Lower levels of herbivory imply lower abundances of herbivorous insects, which could in turn result in lower abundances of predatory insects, insect-eating birds, and so on.

Versailles’s Hidden Scientific Legacy to Surface in a Major U.K. Exhibition - The five-mile-squared grounds were mapped out by geometricians and astronomers; keeping the 14,000 fountains bubbling further required developing an unprecedented hydraulic engineering system. AND… Giovanni Domenico Cassini, who headed the Paris Observatory, turned skyward, mapping the moon with a precision that wouldn’t be matched until the late 19th century. AND… Hundreds gathered in the courtyard of Versailles to watch the flight of a hot-air balloon, agronomists developed a hardier potato capable of feeding the masses, and an inoculation against smallpox was discovered.

Air conditioning causes around 3% of greenhouse gas emissions. How will this change in the future? – The article concludes: “Rather than lamenting air conditioning's impact on energy use, we need to accept that demand for cooling will increase, work on making it affordable for those who need it most, and build efficient solutions that ensure electricity grids worldwide can cope.”

Ancient Rome’s Appian Way Is Now a UNESCO World Heritage Site - Rome’s Appian Way, an ancient highway dating to the fourth century B.C.E., has been declared a UNESCO World Heritage site.

Could the shingles vaccine lower your risk of dementia? - The idea that vaccination against viral infection can lower the risk of dementia has been around for more than two decades. Associations have been observed between vaccines, such as those for diphtheria, tetanus, polio and influenza, and subsequent dementia risk. It may be the resulting lack of viral infection creating this effect. We need more research exploring in greater detail how infections are linked with dementia. This will help us understand the root causes of dementia and design potential therapies.

Archaeologists Find a Cache of Ancient Murano Glass Off Bulgarian Coast - Underwater archaeologists in Burgas, Bulgaria have discovered over 100 glass objects dating back to the days of the Ottoman empire in the nation’s Chengene Skele bay. It is speculated that the glass artifacts fell from the cargo of a ship battered by a storm in the shallow, rocky area of the sea. Experts attribute the glass objects to Murano, a Venetian island still renowned today for its fine glassware, likely made in the late 16th and early 17th centuries.

Want the health benefits of strength training but not keen on the gym? Try ‘exercise snacking’ – Great idea!

Timing is everything: Study finds link between bowel movement frequency and overall health – The research showed that if stool sticks around too long in the gut, microbes use up all the available dietary fiber, which they ferment into beneficial short-chain fatty acids. After that, the ecosystem switches to fermentation of proteins, which produces several toxins that can make their way into the bloodstream. They showed that the microbial composition of study participants' gut microbiomes was a telltale sign of bowel movement frequency. Fiber-fermenting gut bacteria, often associated with health, appeared to thrive in a "Goldilocks zone" of bowel movement frequency, where people pooped between 1-2 times per day. However, bacteria associated with protein fermentation, or the upper gastrointestinal tract tended to be enriched in those with constipation or diarrhea, respectively.

Replacing Fuel Tax A Government Quandary - As the proportion of electric cars on the roads rise, what will fill the funding gap left by the loss of gasoline and diesel tax? One possibility is a road user charge (RUC).

Scientists Find an Underground Cave on the Moon That Could Shelter Future Explorers - Radar data from NASA’s Lunar Reconnaissance Orbiter (LRO) points to the presence of a cave beneath the moon’s surface. Such caves could serve as shelters for future human explorers, since they could protect astronauts from the moon’s hazardous surface environment. (Note – LRO was launched in 2009. My daughter, as an undergraduate, did some of the initial image calibration work!)

With CO2 Levels Rising, World’s Drylands Are Turning Green - Southeast Australia has been getting hotter and drier. Droughts have lengthened, and temperatures regularly soar above 95 degrees F (35 degrees C). Bush fires abound. But somehow, its woodlands keep growing. One of the more extreme and volatile ecosystems on the planet is defying meteorology and becoming greener. Long-term studies by University of California, Riverside in the Sonoran Desert show that shorter shrubs better adapted to less rainfall and higher temperatures are moving in at the expense of native plants, creating an impression of greening that marks an ecological breakdown.

Why Are Amphibians the Most Endangered Class of Animals? - Amphibians are the most endangered class of animals in the world, with 41% facing extinction. Climate change on its own would not be such an incredible threat if it weren’t for the toll it takes when combined with habitat loss, fragmentation and disease.

New solutions to keep drinking water safe as pesticide use skyrockets worldwide - A 62% rise in global pesticide use in the past 20 years has escalated fears that many of these chemicals could end up in our waterways, causing cancer. Powdered activated carbon (PAC) is currently used to remove organic pesticides from drinking water, but the process is costly, time consuming and not 100% effective. The researchers found that reducing the PAC particles from the existing commercial size of 38 μm (one millionth of a metre) to 6 μm, up to 75% less powder was needed to remove six common pesticides, achieving significant water treatment savings.

Huge! The Massive and Mystical Jordanian Monument to an Enigmatic People - The ancient city of Petra. Known as the “Rose City” for the warm pink blush of the sandstone cliffs it is carved out of, Petra was built by the enigmatic Nabateans. Built over two millennia ago, it was long lost to the shifting sands of Jordan’s desert until it was rediscovered by European travelers in the early 1800s.

Melting Sea Ice Is Making the Northwest Passage More Dangerous - Old, thick chunks of sea ice that tend to cluster near the North Pole are increasingly drifting southward toward Canada and into the path of ships. The younger, thinner ice that once held older ice in place is becoming scarcer as the region warms. For the cargo vessels, fishing boats, and cruise ships crossing the northwest passage, drifting chunks of old, thick sea ice pose a significant threat.

Could the world famous Roman Baths help scientists counter the challenge of antibiotic resistance? – A diverse array of microorganisms were found in the hot waters of the Roman Baths. Tests showed 15 of the isolated bacteria -- including examples of Proteobacteria and Firmicutes -- displayed varying levels of inhibition against human pathogens including E.coli, Staphylococcus Aureus and Shigella flexneri.

The Changing Nature of Wilderness - The U.S. government has begun to acknowledge the Indigenous history of ‘wilderness’ areas and, in some (very few) cases, restored land to native tribes or created co-management agreements.

Nearly 25% of land in Africa has been damaged – What’s to blame, and what can be done - The “big five” drivers of land degradation globally and in Africa are:

• biological invasions, where plant species have spread outside their indigenous area and disrupted the services provided by ecosystems

• climate change driven events, such as intense droughts and severe fires

• extractive activities, such as mining and over-harvesting

• habitat transformation or fragmentation, including deforestation and poor agricultural practices

• pollutants such as sulfur dioxide, and eutrophication – where algae and other plants take over plant life.

The Hunt: Genghis Khan’s Final Resting Place - His last wish was to be buried in secret, something his soldiers accomplished in two ways: by killing everyone they met enroute to the gravesite, and then trampling that site under the hoofs of their horses until no trace was left. Although tomb culture, inherited from the neighboring Chinese, was well-established by the time Genghis Khan was born, many were constructed underground, some at a depth of more than 65 feet. Most Mongolians today would prefer that Genghis Khan’s tomb stayed hidden. Not because discovering it would unleash an ancient curse—a superstition that was actually quite widespread in Soviet times—but simply out of respect for the historical figure’s dying wish.

Airplane noise exposure may increase risk of chronic disease - Research has shown that noise from airplanes and helicopters flying overhead are far more bothersome to people than noise from other modes of transportation, and a growing body of research suggests that aircraft noise is also contributing to negative health outcomes.

New fossils show what Australia’s giant prehistoric ‘thunder birds’ looked like – and offer clues about how they died out - While the birds had broad, short toes and hoof-like claws for moving across open ground between bodies of water, their partial reliance on freshwater and new plant growth would have become more difficult as ponds and lakes shrunk and disappeared.

Phoenix Heat Deaths Rose by 1,000 Percent in 10 Years - Relentless heat led to 645 deaths last year in Maricopa County, the most ever documented in Arizona’s biggest metropolitan area. Almost half of the victims last year were homeless — 290 people. Twenty died at bus stops, others were in tents, and an unrecorded number of people were found on the pavement, prone as if on a baking stone.

Warming Brings Early Bloom to Bulgarian Rose Fields – Bulgaria is a top producer of rose water and rose oil. To produce these goods, pickers must harvest the flowers early in the morning, when their petals are richest in oil. After a mild winter and warm spring, pickers in Bulgaria’s Rose Valley have headed to the fields around three weeks earlier than normal.

Korean Art History eBooks

Internet Archive had 14 of the 15 volumes of the Chōsen koseki zufu – published beginning in 1915 in Japanese and full of illustrations of Korean antiquities. It was the result of the Japanese work to systemically organize and investigate cultural assets and sites throughout the Korean Peninsula after they annexed the country in 1910.

Most of what I know about Korea is in the context of the Korean War of the 1950s and, more recently, the products from South Korea that are exported to the U.S. These books enlarged my understanding of the deep history of the country via the pictures (although I probably would have gotten even more from the books if I could read Japanese!). I have selected a sample image from each volume…but there are many more in the books…well worth the time to browse.

A new way to quantify climate change impacts: 'Outdoor days' - Noting the number of days per year that outdoor temperatures are comfortable enough for normal outdoor activities. In the North, in a place like Russia or Canada, you gain a significant number of outdoor days. And when you go south to places like Bangladesh or Sudan, it's bad news. You get significantly fewer outdoor days.

Is filtered water healthier than tap water? - Water filters, it seems, are having a heyday – particularly in North America, Europe, and China. I was a little surprised that the article did not mention microplastics in water – even in countries that have relatively high standards for their water supplies.

Baltimore’s Toxic Legacies Have Reached a Breaking Point – “Normal” southwest of the collapsed Frances Scott Key Bridge in Baltimore…one of the most polluted places in the U.S. – a different perspective on the bridge collapse.

European ruling linking climate change to human rights could be a game changer — here’s how - On 9 April, the European Court of Human Rights delivered a groundbreaking ruling: states are obliged to protect their citizens from the threats and harms of climate change. And in that regard, judges said, Switzerland’s climate action has been inadequate. Without prescribing specific years or percentage reductions, the ruling set out how a nation can show it is compliant. It must set out a timetable and targets for achieving carbon neutrality, and pathways and interim targets for reducing greenhouse-gas emissions. Measures must be implemented in a timely, appropriate, and consistent manner. Governments must also provide evidence that they have complied with targets, and update targets regularly.

Positive perceptions of solar projects - A new survey has found that for U.S. residents living within three miles of a large-scale solar development, positive attitudes outnumbered negative attitudes by almost a 3-to-1 margin.

18th-Century Foundation Uncovered at Colonial Williamsburg – Even in much studied areas, there are still new things to discover!

Metabolic health before vaccination determines effectiveness of anti-flu response - Metabolic health (normal blood pressure, blood sugar and cholesterol levels, among other factors) influences the effectiveness of influenza vaccinations….even in people with obesity which the vaccine had previously been documented as being less effective.

The environmental cost of China's addiction to cement - Today, China still accounts for just over half of the world's total annual 4.1bn tons of cement production (52%) – followed by India (6.2%), the EU (5.3%) and the US (1.9%). Little of that cement produced in China is exported. In 2020 the country used an estimated 2.4 billion tons of cement, 23 times the amount used in the US in the same year.

Teotihuacan's Pyramids Damaged by Ancient Earthquakes – Damage from megathrust earthquakes at the site between about AD 100 and 600: fracturing and dislodging of large masonry blocks used to construct the buildings, as well as chipping of blocks that comprised the pyramids' outer stairs.

Mini-colons revolutionize colorectal cancer research - Scientists have combined microfabrication and tissue engineering techniques to develop miniature colon tissues that can simulate the complex process of tumorigenesis outside the body with high fidelity, giving rise to tumors that closely resemble those found in vivo….offering a new path to research colon cancers and their treatment.

Meet the World’s Largest Freshwater Crayfish – The Tasmanian giant crayfish. Their numbers are declining due to fishing and disturbance.

FDA urges Congress to pass bill mandating food manufacturers test for lead – I am surprised Congress did not pass this already. According to the U.S. Disease Control and Prevention, there have been at least 519 confirmed, probable and suspect cases of lead and chromium poisoning traced to imported applesauce pouches produced by brands WanaBana, Schnucks and Weis. Lead exposure in children is associated with learning and behavior problems, as well as hearing and speech issues and slowed growth and development.

Retention ponds can deliver a substantial reduction in tire particle pollution - The presence of wetlands and retention ponds alongside major highways led to an average reduction of almost 75% in the mass of tire wear particles being discharged to aquatic waters. Tire wear particles significantly outweighed other forms of microplastics, such as plastic fibers and fragments.

Climate change is fueling the US insurance problem – I’ve seen more articles about this recently….there is no good news re insurance…nothing that can overcome what climate change is doing. One state-level action that could help mitigate the impacts of climate change is the implementation of flood disclosures. Organizations like the Natural Resources Defense Council have urged states to require flood disclosure polices during property sales to help buyers decide whether buying is worth the risk. Research has shown disclosure can devalue flood-prone properties and discourage development in risky areas. Even though the number of states requiring flood disclosure policies is slowly increasing, Florida remains noticeably absent, and one-third of states still have no requirement that sellers must disclose a property's flood risk to potential buyers.

Does the time of day you move your body make a difference to your health? – Maybe – for people living with obesity.

How the iron lung paved the way for the modern-day intensive care unit – The iron lung was first used to save the life of a child in 1928. It swiftly became a fixture in polio wards during the polio outbreaks of the subsequent decades, particularly from 1948 until the vaccine was developed in 1955. And its creation paved the way for many subsequent medical innovations. Some patients spent just a short time in the iron lung, perhaps weeks or months until they were able to regain chest strength and breath independently again. But for patients whose chest muscles were permanently paralyzed, the iron lung remained the key to survival.

Food security in developed countries shows resilience to climate change - Data on American wheat production, inventories, crop area, prices and wider market conditions from 1950 to 2018, together with records of annual fluctuations in the weather for the same period reveals strong evidence of an increase in weather and harvest variability from 1974 onwards. However, Wheat prices remain relatively stable, along with the price of associated goods mainly due to farmers and agricultural industries providing a buffer, smoothing out any bumps in the supply of grain to retailers and consumers.

Where the Xerces Blue Butterfly Was Lost, Its Closest Relative Is Now Filling In - Silvery Blues collected 100 miles south of San Francisco were released at a restored a swath of dunes in the Presidio, a former military base, trying to bring back native wildlife. They will pollinate native flowers and form a critical link in the food chain there.

Colorless, odorless gas likely linked to alarming rise in non-smoking lung cancer - 5-20% of newly diagnosed lung cancers occur in people who have never smoked, many of whom are in their 40s or 50s.  Non-smoking lung cancer cases is likely linked to long-term, high exposures of radon gas. This colorless, odorless gas is emitted from the breakdown of radioactive material naturally occurring underground that then seeps through building foundations. The gas can linger and accumulate in people's homes and lungs silently unless they know to test for it. We had our Missouri house tested and radon remediation installed before we moved it!

Contents of Roman Lead Coffin Examined in England - The examination of the contents of a Roman lead coffin discovered in 2022 in the city of Leeds has identified the partial remains of a child (about 10 years old). The initial evaluation of the coffin’s poorly preserved contents found the remains of a woman between the ages of 25 and 35 at the time of her death some 1,600 years ago, a bracelet, a glass bead necklace, and a finger ring or an earring.

Feral Hogs to Be Removed from Congaree National Park – My husband and I visited Congaree in 2008 and I vividly remember the feral hogs. Evidently action is being taken to remove them. They have become a pervasive problem to both the park and surrounding landowners, routinely causing widespread damage to land and water resources both within and outside of the park. Recent observations have shown that they have begun to cause more extensive damage to areas near the Harry Hampton Visitor Center, including areas where synchronous fireflies are active and where restoration of longleaf pine is ongoing.

What four decades of canned salmon reveal about marine food webs - The cans contained fillets from four salmon species, all caught over a 42-year period in the Gulf of Alaska and Bristol Bay. Researchers dissected the preserved fillets from 178 cans and counted the number of anisakid roundworms -- a common, tiny marine parasite -- within the flesh. The parasites were killed by the canning process but still visible… counting them is one way to gauge how well a marine ecosystem is doing.

Texas Solar Power Growth Changing the Shape of Daily Electricity Supply in ERCOT – Looking at the changes between 2022 and 2023…easy to see graphically.

Functional capacity in old age is like an ecosystem that may collapse when disrupted - In old age, a tighter interlinkage between different domains of functional capacity may indicate a loss of system resilience. When functional capacity domains are tightly interconnected, a disruption in one domain can affect others and lead to a collapse in functioning.

Ming Dynasty Tomb Found in China's Xinfu District – Part of excavations before nearby highway construction begins.

I spy with my speedy eye: Scientists discover speed of visual perception ranges widely in humans - The rate with which we perceive the world is known as our "temporal resolution." Though our visual temporal resolution is quite stable from day to day in general, a post-hoc analysis did suggest that there may be slightly more variation over time within females than within males.

Study Reveals Vast Networks of ‘Ghost Roads’ in Asian Rainforests - An extensive analysis of satellite imagery has uncovered thousands of miles of unmapped roads slicing through Asia’s tropical rainforests - “ghost roads” may be laid down by miners, loggers, poachers, drug traffickers, and land grabbers, often illegally.

What do terracotta warriors tell us about life in ancient China? – Discovered 50 years ago…they are a snapshot of the soldiers of Qin – the feudal state that unified China, for the first time in 221BC under the country's first emperor Qin Shi Huang – from the soles of their shoes to their candy-colored clothes to the bronze weapons buried with them to their distinct facial features. 2,000 terracotta warriors have been excavated but more are uncovered every year.

This Map Shows Where Planting Trees Would Make Climate Change Worse - Trees draw down carbon dioxide from the atmosphere, helping to keep warming in check. But their dark, green leaves also absorb heat from sunlight. Snow and sand, by virtue of their light color, reflect more sunlight back into space. As such, trees planted in snowy areas or in the desert will absorb more sunlight than their surroundings, which may negate the climate benefits of soaking up carbon dioxide.

These 3,000-Year-Old Treasures Were Forged from Meteoritic Iron - In the 1960s, researchers discovered a trove of Bronze Age treasure in Villena, Spain. New research has revealed that some of them made between 1400 and 1200 B.C.E. were forged from iron from a meteor that struck Earth a million years ago. Who manufactured them and where this material was obtained are still questions that remain to be answered.

Vernal Pools Make Your Garden Sing - It’s not just frogs that are making homes in these little pools of water. Less vocal species like salamanders, dragonflies, fairy shrimp, and even dozens of native plants are there too. Even more species than that can be found simply visiting the pool for a drink or snack, including great blue herons, wood ducks, and box turtles.

Return of Trees to Eastern U.S. Kept Region Cool as Planet Warmed - Over the 20th century, the U.S. warmed by 1.2 degrees F (0.7 degrees C), but across much the East, temperatures dropped by 0.5 degrees F (0.3 degrees C). A new study posits that the restoration of lost forest countered warming, keeping the region cool. Still, the return of trees can only partially account for the drop in temperature. Other possible explanations include the growth of irrigation, a source of water vapor, and the uptick in particulate pollution, which reflects sunlight, thereby cooling the air.

Sweetened drinks linked to atrial fibrillation risk - 20% higher risk of irregular heart rhythm, known as atrial fibrillation, among people who said they drank two liters or more per week (about 67 ounces) of artificially sweetened drinks. The risk was 10% higher among people who said they drank similar amounts of sugar-sweetened beverages.

Measles outbreaks and what parents need to know - Measles can lead to complications such as ear infections, diarrhea, pneumonia, and encephalitis (brain swelling). One to three of every 1,000 children infected with measles dies. More than 97 percent of the people who have had their two shots of the vaccine never get measles.

A new world of 2D material is opening up - 2D materials have shown great potential for an enormous number of applications. You can imagine capturing carbon dioxide or purifying water, for example. Now it's about scaling up the synthesis and doing it in a sustainable way.

In Cleveland, mushrooms digest entire houses: How fungi can be used to clean up pollution - Fungi can eat the noxious waste from abandoned homes. Heavy metals and other toxins are extracted and captured in the mushrooms that grow, while the substrate leftovers, including the mycelium, are compacted and heated to create clean bricks for new construction. The resulting "mycoblocks" have a consistency akin to hardwood and, depending on the specifics of the manufacturing process, have been shown to be significantly stronger than concrete.

Under Threat in Their Native California, Giant Sequoias Are Thriving in Britain - First introduced to country estates in the 19th century, half a million sequoias now grow in Britain, compared to just 80,000 along the western flank of the Sierra Nevada in California, where they are increasingly imperiled by warming. Up to a fifth of all large giant sequoias in California died in wildfires in 2020 and 2021. The trees in Britain are still relatively young — sequoias can live for more than 3,000 years — and squat. In Britain’s cool, mild climate, sequoias are growing nearly as fast as in California.

Whales That Go Through Menopause Live Longer and May Help Care for Grandchildren - Female tooth whales that go through menopause (narwhals, killer whales, false killer whales, short-finned pilot whales and beluga whales) have longer lifespans than those that don’t, surviving decades past their reproductive prime!

A healthier diet is linked with a slower pace of aging, reduced dementia risk - We have some strong evidence that a healthy diet can protect against dementia…but the mechanism of this protection is not well understood. This study suggests that slower pace of aging mediates part of the relationship of healthy diet with reduced dementia risk, and therefore, monitoring pace of aging may inform dementia prevention. Additional observational studies need to be conducted to investigate direct associations of nutrients with brain aging.

The next pandemic? It’s already here for Earth’s wildlife – The pathogenic strain of avian influenza has killed millions of birds and unknown numbers of mammals. Between January 1, 2003 and December 21, 2023, 882 cases of human infection were reported from 23 countries, of which 461 (52%) were fatal. To prevent the worst outcomes for this virus, we must revisit its primary source: the incubator of intensive poultry farms.

Ultra-fast fashion is a disturbing trend undermining efforts to make the whole industry more sustainable - Ultra-fast fashion is marked by even faster production cycles, blink-and-you’ll-miss-it trends, and poor labor practices. Without change, the industry will account for 26% of the world’s carbon budget for limiting global warming to 2°C by 2050. Established brands such as Gap introduce 12,000 new items a year and H&M 25,000. But Shein leaves them in the dust, listing 1.3 million items in the same amount of time.

The benefits of trees – From an architect’s perspective…working with trees rather than just around them.

How the color orange got its name – Orange was my mother’s favorite color for many years. She had the door of the house they built painted orange! So - this post caught my attention. In English, before the turn of the 16th century, orange objects would be simply known as “yellow-red” or “geoluhread” in Middle English. There are also records of the word “saffron” being used to as a replacement for “orange” as a descriptor. Oranges, the fruit, take their name from the Sanskrit nāraṅga meaning orange tree. Nāraṅga morphed via the Persian word nâranj and the French pomme d’orenge, meaning “apple of the orange tree.”

Quality time with Pocket Gophers - Pocket gophers spend most of their lives underground. There are some 38 species found across a wide swath of central and North America. In many areas, they’re abundant. And yet, many people have never seen one.

Scientists shocked to discover new species of green anaconda, the world’s biggest snake - Green anacondas are the world’s heaviest snakes, and among the longest. Predominantly found in rivers and wetlands in South America, they are renowned for their lightning speed and ability to asphyxiate huge prey then swallow them whole. New research upends scientific understanding of this magnificent creature, revealing it is actually two genetically different species. The snakes are well-adapted to a life lived mostly in water. Their nostrils and eyes are on top of their head, so they can see and breathe while the rest of their body is submerged. Anacondas are olive-colored with large black spots, enabling them to blend in with their surroundings. The two species of green anaconda look almost identical, and no obvious geographical barrier exists to separate them. But their level of genetic divergence – 5.5% – is staggering. By comparison, the genetic difference between humans and apes is about 2%.

Helping caregivers help people with dementia eat at home - Over 80% of people with dementia in the United States live at home. An estimated 60% of home-based patients aren't able to routinely eat or prepare food on their own. Professionals recommended:

• Lowering auditory and visual distractions.

• Eliminating household clutter, clearing pathways and improving lighting.

• Providing written instructions to guide patients' mealtime activities.

Peek Inside the Ancient Egyptian Tomb of Neferhotep, Now Open to the Public - Revitalizing ancient artifacts is no easy lift. All the wall paintings, reliefs, and sculptures required stabilizing loose stone fragments, cracks, detached plaster, and paint layers, not to mention cleaning and preserving surfaces damaged by fire and time. The restoration project started in 2000.

Discovering Mammoth Cave’s Oceanic Past - Creatures that lived in an ancient seaway that covered the landscape known today as Kentucky some 325 million years ago: crinoids, horn coral, brachiopods…small dark slashes that indicate shark teeth…a dorsal fin spine…a large piece of shoulder skeletal cartilage.

Saguaro Arms and Other Cactus Musings in Tucson – Remembering Saguaro National Park from my daughter’s graduate school years in Tucson. The research about the arms is interesting: The working theory is that saguaros start their branching at a certain size, not a certain age. Initial data indicates that saguaros tend to grow their first arm facing the south or southeast, often when they’re around 11-feet tall. Second arms often grow facing north. Arms seem to grow in a way that maintains symmetry and allows the saguaro to keep its balance.

Apples, Walnuts… and Toast? A New Study Reveals the Flavors of Ancient Roman Wine - Georgian vintners still employ a rustic approach. Grapes are crushed by hand or foot, placed in egg-shaped vessels known as qvevri, and buried for up to six months. It’s a UNESCO-recognized tradition dating back 8,000 years and researchers believe can help reveal the sight and scent of ancient Roman wine.

Mexico is suing US gun-makers for arming its gangs − and a US court could award billions in damages - In January, a federal appeals court in Boston decided that the industry’s immunity shield, which so far has protected gun-makers from civil liability, does not apply to Mexico’s lawsuit. Mexico’s lawsuit alleges that U.S. gun-makers aided and abetted illegal weapons sales to gun traffickers in violation of federal law. According to the lawsuit, feeding demand for illegal weapons is central to the industry’s business model.

Climate change reversing gains in air quality across the U.S.: study - The study finds that climate change is increasing the prevalence of two of the air pollutants most harmful to human health: particulate matter, commonly referred to as PM2.5, and tropospheric ozone. Whereas pollutants from cars and factories could be targeted by regulations over the past few decades, climate-related deterioration in air quality is a much tougher problem to solve.

Avar Grave Offers Clues to 7th-Century Heavy Cavalry - Thought to be a complete set of lamellar armor, which was made from hundreds of small iron plates, was spread out over the warrior.

What Does a Solar Eclipse on Mars Look Like? New, Breathtaking Images, Caught by NASA’s Perseverance Rover, Give Us an Idea – Images of Phobos passing across the sun’s surface…back on February 8.

Benefits of heat pumps - Nationally, heat pumps would cut residential sector greenhouse gas emissions by 36%-64%!

How millennials could give the suburbs a much-needed makeover – The trend is to move to the suburbs and not feel like you need to go to the city to have a great dinner or to see a show or live music or the arts.

The far-reaching impacts of wildfire smoke – and how to protect yourself - One study found that a quarter of the US's PM2.5 pollution was caused by wildfire smoke. In western regions, as much as half was caused by smoke. If there is a wildfire nearby, the Centers for Disease Control and Prevention advise taking steps to limit your exposure where possible:

Choose a room to close off from outside air

Wear a tightly fitting respirator, if it is safe for you to do so

Keep track of fires nearby using services such as AirNow's fire and smoke map

Pay attention to health symptoms and seek medical care if needed

Ancient Lipstick Dating Back More Than Three Millennia Is Found in Iran – Analysis of the loose, dark purple fine powder revealed minerals (hematite, quartz, braunite, anglesite, and rare tiny crystals of galena) and vegetal fibers.

In Scotland, Renewable Power Has Outstripped Demand – A milestone for Scotland. The volume of electricity produced by renewables in Scotland was equal to 113 percent of demand in 2022. Fossil fuels still supply some electricity, helping to smooth over gaps in renewable power. Across the U.K., fossil fuel power is at its lowest level in nearly seven decades. Impressive.

Gleanings of the Week Ending February 24, 2024

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.

Surprisingly vibrant color of 12-million-year-old snail shells – Polyenes (includes carotenoids) preserved almost unchanged…and found in fossils.

Asbestos: The strange past of the 'magic mineral' – Asbestos was woven into textiles fit for kings and used for party tricks. One 18th-Century philosopher even slept in a night-cap made from it. It was also used to make the funerary shrouds for monarchs; because it didn't burn, it helped to keep their ashes separated from the rest of the pyre. An account from Ancient Greece describes a golden lamp made for the goddess Athena, which could reportedly burn for a whole year without going out and had a wick made from "Carpathian flax" – thought to be another name for asbestos. In 1899, an English doctor recorded the first confirmed case of a death linked directly to the material – a 33-year-old textile worker who had developed fibrosis of the lungs. In the UK, all asbestos was banned in 1999, but much of the asbestos added before this date remains in place – as buildings degrade, it is posing a significant health risk.

Rise of Peru’s Divine Lords – Hilltop sites in the Andes…early examples of divine lordship - a form of leadership that would endure in Peru for more than 1,000 years.

Amid Record Drop in Fossil Power, Europe Sees Wind Overtake Natural Gas - The E.U. power sector is undergoing a monumental shift - fossil fuels are playing a smaller role than ever as a system with wind and solar as its backbone comes into view. Coal generation fell by 26 percent, while gas generation fell by 15 percent.

Student Design Competition: Integrating Solar and Agriculture - Some 2.8 gigawatts of agrivoltaics exist across the U.S. Many combine solar energy with pollinator habitat and sheep grazing. The National Renewable Energy Laboratory (NREL) is looking for new design proposals from graduate and undergraduate landscape architecture students to push the agrivoltaics envelope!

The Moon Is Shrinking, Causing Moonquakes at a Potential NASA Landing Site - Researchers examined data on moonquakes detected by lunar seismometers, which have been on the moon since Apollo program astronauts left them there more than 50 years ago. They also used mapping data from NASA’s Lunar Reconnaissance Orbiter to identify the telltale creases on the moon. Through modeling, they linked these faults to seismic activity.

Texas Reservoirs Reach Dangerous Lows - In Corpus Christi, on the south Texas coast, authorities last month stopped releasing water aimed at maintaining minimum viable ecology in the coastal wetlands, even as oil refineries and chemical plants remain exempt from water use restrictions during drought. On the lower Texas coast, the Rio Grande has not been flowing consistently, and Colorado River water releases have been minimal as that river faces shortages farther upstream.

Extreme Birding: Gull Watching at the Landfill - You can find gulls around North America (and many parts of the world), including in interior states. At least 28 gulls can be seen in North America, with additional vagrant species showing up from time to time. Individual species look different depending on age and other factors. A gull goes through three feather molts in its first year.

Poisonous Seed Stash Discovered in the Netherlands – Black henbane contained in a hollow goat (or sheep) thigh bone sealed with a plug of black birch bark…from AD 70-200.

Ocean Sponge Skeletons Suggest a More Significant History of Global Warming Than Originally Thought - An analysis of six sea sponges—centuries-old creatures with an internal chemistry that holds secrets about climate history—points to global temperatures already having increased by 1.7 degrees Celsius due to human activity --- that’s more than scientists currently agree upon….so there is a flurry of activity to corroborate the finding.
