American Schools Have Been Feeding Children for More Than 100 Years. Here’s How the School Lunch Has Changed - The National School Lunch Program is the longest running children’s health program in U.S. history, and it has an outsized impact on nutritional health.

Pompeii’s Most Fascinating Finds of the Decade—So Far - From children's drawings to ancient fast-food counters, new finds continue to reshape our understanding of daily life in the ill-fated Roman city. very year, archeologists come across remains and artifacts that broaden our understanding of what daily life in Pompeii and, by extension, the rest of the Roman Republic was like.

Where in the world are babies at the lowest risk of dying? – Data collected by countries…and then tweaked to be made more consistent so that comparisons can be done. It’s about how to look at statistical data.

How gardening can help you live better for longer - In 2015, Norway became one of the first countries to create a national dementia care plan, which includes government-offered daycare services such as Inn på tunet – translated as "into the yard" – or care farms. Now, as researchers recognize the vast cognitive benefits of working on the land, more communities are integrating gardening into healthcare – treating all kinds of health needs through socially-prescribed activities in nature, or green prescriptions.

Chasing Unicorns: A Photographer’s Journey Documenting Rhino Conservation - Bringing the rhinos from one conservancy to another was a monumental effort. A photographer documented the work of conservationists and veterinarians.

Gilded-Age Tiffany Window Heads to Auction with Multimillion-Dollar Price Tag - With most surviving examples of Louis Comfort Tiffany’s mastery of mottled glass still affixed to the walls of churches or stately homes, purchasing opportunities are rare.

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.

163 Treasures from King Tut’s Tomb Arrive at the Grand Egyptian Museum - The museum one step closer to staging the first-ever complete display of the legendary boy king’s golden treasures. I remember the two King Tut exhibits I have views – in New Orleans and Baltimore.

Sulfur runoff amplifies mercury concentrations in Florida Everglades - Sulfur applied to sugarcane crops in South Florida is flowing into wetlands upgradient of Everglades National Park, triggering a chemical reaction that converts mercury into toxic methylmercury, which accumulates in fish.

Foraging Violets – I have a lot of violets growing in my yard…and I am going to start harvesting them for salads. Why buy fresh greens when there is such a plentiful supply that I can pick just before I eat them?

The Unexpected Science of Staying Happy – An article about the World Happiness Report. The U.S., Canada, and Switzerland—all once top 10 contenders—have dropped out of the top 20 for the first time since the report began. That decline is linked to a drop in social trust and a rise in what researchers call “deaths of despair,” especially among men over 60​.

The 120-Year-Old Tiny Home Villages That Sheltered San Francisco’s Earthquake Refugees – A different perspective on history….more substantial than tents.

Exquisite Street Photography Celebrates the Different Moods of New York City at Night – More umbrellas than I expected.

Relics of a Red World in Bighorn Basin – Satellite image of “red beds” in northern Wyoming and Southern Montana formed when the land was part of Pangea and there were extreme wet/dry seasons causing hematite in the rocks to oxidize (rust). The area is rich in fossils and oil/gas reserves.

Tree Rings Bear Witness to Illegal Gold Mining Operations in the Amazon, New Study Finds – The miners use liquid mercury which is then burned to obtain the gold….releasing toxic mercury into the air. Core samples from trunks of fig trees show the mercury levels…when they ramped up and how substantial they were/are.

Smoke from US wildfires, prescribed burns caused premature deaths, billions in health damages - Researchers estimated that smoke from wildfires and prescribed burns caused $200 billion in health damages in 2017, and that these were associated with 20,000 premature deaths. Senior citizens were harmed the most.

Rare ‘Doomsday’ Oarfish Surfaces in California, Just the 20th Discovered in the State Since 1901 - Usually lives as far as 3,280 feet below the surface. Scientists conducted a necropsy, but they couldn’t discern a reason for the elusive fish’s death. Scientists aren’t totally sure why oarfish and other deep sea-dwelling creatures sometimes surface, but they suspect the animals may be disoriented, sick or injured.

Owl-Inspired “Bionic” Fan for EVs Reduces Fan Noise 50% While Improving Efficiency 10% - Making EVs even quieter!

Do you have knee pain from osteoarthritis? You might not need surgery. – Article written by researchers in Australia about the updated treatment guidelines for knee osteoarthritis that stress exercise, increasing physical activity, weight management, and pain medication (in moderation and not opioids). The links at the end of the article include an online exercise program specifically for knee osteoarthritis.

Frank Lloyd Wright’s Only Skyscraper Set to Close Amid Controversy – Price Tower in Bartlesville, Oklahoma. Built in 1956. Designated a National Historic Landmark in 2007.

Rebuilding the Genome of Woolly Mammoths - Typically, ancient DNA fragments yield short snippets of DNA and provide an incomplete picture of the genomic puzzle. However, the woolly mammoth skin sample showed promise. The team assembled the first 3D reconstruction of the woolly mammoth’s genome, which had 28 chromosomes; the order of genes was very similar to that of the Asian elephant. They discovered: the specimen was female; differences from modern elephants in the genes related to hair follicle development and, more broadly, hair maintenance; cooling and dehydration can preserve the molecules in their original locations.

Homelessness – From Our World in Data. Interesting…but frustrating too. I was glad that they emphasized when the data is not consistently collected…and the analysis gets very tricky.

Only One Country Is Making Progress on Electrifying Everything – Unfortunately it is not the US…it’s China. The country that electrifies most rapidly and builds the most renewables to power its electrified economy will be the most competitive economy globally.

As Arctic Thaws, New Evidence of Looming ‘Mercury Bomb’ - Scientists estimate that the amount of mercury in the atmosphere has grown sevenfold over the last 500 years, primarily from burning coal. Air currents are carrying airborne mercury toward the Arctic, where it is absorbed by plants, which then deposit the toxin in the soil. Over centuries, mercury has built up in the frozen ground, such that today, Arctic permafrost may hold more mercury than the atmosphere, the oceans, and every living organisms combined. As the region warms, melting permafrost could liberate this buried mercury.

Rare Fossils Give Clues to How Tardigrades Survived Mass Extinctions by Hitting the Snooze Button - Tardigrades are known for being some of the most resilient animals to exist, capable of surviving extreme temperatures, pressure, radiation and starvation—they can even withstand exposure to outer space. Only four known fossils of tardigrades have been found to date, and all of them are preserved in amber, or ancient tree resin; recently they were reanalyzed using confocal fluorescence microscopy. Cryptobiosis is the secret to tardigrades’ incredible resilience, and it appears to have evolved in two tardigrade linages (at least). In survival situations, these hardy creatures will expel the water from their bodies and suspend their metabolism almost completely allowing them to outlast unfavorable conditions of their environment.

Five ways the brain can age: 50,000 scans reveal possible patterns of damage - Results could lead to methods that detect the earliest stages of neurodegenerative disease. Dementia and its precursor, mild cognitive impairment, had links to three of the five patterns. Intriguingly, the researchers also found evidence that the patterns they identified could potentially be used to reveal the likelihood of more brain degeneration in the future. Other patterns were linked to conditions including Parkinson’s disease and Alzheimer’s disease, and one combination of three patterns was highly predictive of mortality.

Dragonflies Reveal Path of Mercury Pollution – Dragonfly larvae collected from 150 national parks and then analyzed for mercury revealed: in arid regions, mercury comes from snow and rain, while in wetter, more forested areas, airborne mercury clings to leaves, which then fall to the ground, where the toxin spreads.

Komodo dragons have iron-coated teeth to rip apart their prey – A clue to how dinosaurs like Tyrannosaurus rex killed and ate their prey.

COVID-19 devastated teacher morale − and it hasn’t recovered - A National Education Association survey of members found that, as of late 2022, a staggering 55% of educators were thinking of calling it quits because of: eroding sense of safety in the school, intense and unrelenting workload, lackluster leadership and changing expectations, and cuts in jobs and budget. Better pay is a start. I was disappointed that this article did not suggest more than that.

Two Baby Condors at Pinnacles National Park Are Healthy, ‘Adorable Fluffballs’ – Avian flu killed at least 20 California Condors in Arizona and Utah last spring…so the health of these birds is great news. So far, their lead levels (often a problem if their parents bring them carrion with bullet fragments) are low. They will make their first flights in October or November.

Biden Designates Baaj Nwaavjo I'tah Kukveni - Ancestral Footprints of the Grand Canyon National Monument – Protecting the land around Grand Canyon National Park.

Nearly Two-Thirds of All Species Live in the Ground, Scientists Estimate - Soils are richer in life than coral reefs or rainforest canopies, providing a home to nearly two-thirds of all species. The study is the first to tally the total number of soil dwellers, large and small, finding that more than twice as many species live in the ground as was previously thought: 59 percent of all species depend on soil for their survival, including 90 percent of fungi, 86 percent of plants, and 40 percent of bacteria.

What Pots Say—and Don’t Say—About People – “What can such a well-traveled artifact tell us about the people who left it in the ground? Its culture of origin may be less important than how it fit into life where it was found.”

Microplastics found in human heart tissues, both before and after surgical procedures - Everywhere scientists look for microplastics, they've found them -- food, water, air and some parts of the human body….even in the heart. But it still is not known how/if the microplastics impact the cardiovascular system.

Microalgae vs. Mercury - In the search for ways to fight methylmercury in global waterways, scientists at Oak Ridge National Laboratory discovered that some forms of phytoplankton are good at degrading the potent neurotoxin.

How an asteroid impact would transform the food we eat – Thought provoking…and scary. Right now, I am beginning to wonder how the level of drought in the US is going to change the food we eat…or will we eat the same way but pay much higher prices.

A Field Guide to Unexpected, Out-of-Place Wildlife – Why wildlife shows up in the ‘wrong’ place… I had read about the shifting range of armadillos last spring (was reminded of it by the reference to the Virginia opossum in this post).

State Of the Birds Report: More Than Half of U.S. Bird Species Are Declining – Sad….another indicator that the Earth is changing.

Economic losses from hurricanes become too big to be offset by the US if warming continues – I’ve been wondering about this since Hurricane Harvey and finally there is some analysis of the data…but, so far, it does not seem to be changing the way we deal with the aftermath of these catastrophic storms. The dominate idea still seems to be ‘rebuild.’

Life expectancy improves in some countries after big drops in 2020 – but US and others see further falls  - The life expectancy at birth in the US was 79.8 in 2019 and was down to 77.4 in 2021. It might take a few years until the impact of COVID-19 on life expectancy is fully understood. It seems to me that there are other cultural changes that happened concurrent with the COVID-19 pandemic that could impact life expectancy in the US into the future: reduced vaccination rates, reduced trust in medical professionals, increased belief in whatever is said on social media and conspiracy theories, increased stress/mental health challenges, etc.

The Clean Water Act at 50: Big Successes, More to Be Done – The Act was passed the year I graduated from high school. I had done a project about algae as pollution indicator in the streams around Dallas, Texas in the fall before so I was aware of water pollution issues of the time. It is frustrating that there is still so much to be done….

New model of Alzheimer’s as an autoimmune disease – A new perspective….maybe leading to new therapies in the future.

Ancient Maya Cities Were Polluted with High Levels of Mercury – The Maya coated surfaces (walls and floors and bodies) with cinnabar…and the mercury from that leached into the water supply and soils. Chronic mercury poisoning causes tremors, weakened vision and hearing, and paralysis! The contamination at some sites is high enough that archaeologists need to use mitigation techniques and protective gear.

Young kids avoid one learning trap that often snares adults – Young kids are not as good at focused attention as adults which means they notice new things happening away from a ‘focus area’ more quickly…..but focused attention can also mean learned inattention in adults which might not be the best strategy in all situations.

After Three Summers, Man Finally Gets Photos of Hummingbird with Rainbow Wings – Beautiful pictures. They prompted me to look up why hummingbird feathers can show the colors of the rainbow. I found a Science Daily post from back in 2020 that offers an explanation.
