See the Face of a 10,500-Year-Old Woman, Reconstructed by Archaeologists and Artists – Based on well-preserved ancient DNA.

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.

Is an apple a day really good for your health? - Eating an apple a day is great– but only if that is part of a diet rich in various other plant-based foods, since that is a key driver of good health.

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.

From Dead Dirt to Healthy Soil in 7 Simple Steps – The articles from Leaf & Limb are always full of practical suggestions. I am doing all 7 of these steps in my yard!

A Large, Invasive Lizard Was Spotted in a California Park – An Argentine black and white tego. Another invasive...probably a pet that escaped or was released. Tegus have established populations in several parts of Florida, where they’ve been declared an invasive species. The lizards have also infiltrated southeast Georgia, and they have been spotted in Alabama, Texas, South Carolina and Louisiana.

Ultra-processed foods are everywhere — and they’re quietly raising health risks - The effects of UPFs can pile up over time, adding to the risk of heart attack, stroke and other serious health issues by raising blood pressure and blood sugar levels. While ultra-processed foods include obvious culprits like potato chips, candy and frozen pizza, there are also some that people may believe are good for them, such as packaged granola bars, sports drinks and fruit-filled yogurt.

The hunt for Marie Curie's radioactive fingerprints in Paris - Marie Curie worked with radioactive material with her bare hands. More than 100 years after her groundbreaking work, the lingering radioactive fingerprints she left behind are still measurable.

5 simple (and cheap) things to make your house use less energy - Climate solutions for reducing home energy use can be extremely simple — and sometimes even free.

When Rivers Take a Weird Turn – Two examples where water (river) flows in unexpected ways…with satellite images from Landsat 9 of the two areas.

6 feel-good exercises to alleviate sore, achy feet – Some of these were new-to-me. I’m trying them all!

Is it better to neglect your garden? – Maybe…except for stepping in strategically to keep invasives from taking over. My yard is a work in progress but the goal it to make changes that mean it will require less and less intervention over time.

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.

Southern Magnolia Petals as Seasoning

I was surprised when my daughter told me that southern magnolia petals were edible. My son-in-law has started a batch of kombucha using the petals for the flavoring. She brought two freshly picked petals from their tree for me to try. She and I ate one of the petals raw. They are very spicy…gingery with a hint of other flavors…pleasant. I put the second one in the refrigerator and used half of it to season a veggie stir-fry side for lunch the next day.

The flavor worked well with the mushrooms, carrots, and celery. The only other seasoning I used was onion flakes and a little salt. The flavor in the stir fry was milder than eating the petal raw…I enjoyed it because it was quite different than my usual stir fry seasoning. I slivered the other half of the petal and put it in a small container in the freezer to use later.

Most of the flowers are too high in the tree to harvest – but it is thrilling to utilize a plant for food that I always assumed was only ornamental. This seems to be the year for discovering edible plants well established around our homes (the earlier one was violets…they are much easier to harvest)!

Millions of new solar system objects to be found and 'filmed in technicolor' -- studies predict – The era C. Rubin Observatory ‘first look’ event is June 23! It is located on Cerro Pachon ridge in northern Chile. I found myself wondering how the deep funding cuts in the US will impact the facility and the scientists involved.

How electric scooters are driving China's salt battery push - Even as the rest of the world tries to close its gap with China in the race to make cheap, safe and efficient lithium-ion batteries, Chinese companies have already taken a head-start towards mass producing sodium-ion batteries, an alternative that could help the industry reduce its dependence on key raw minerals. A bigger market for sodium-ion batteries may be energy storage stations, which absorb power produced at one time so it can be used later.

Dead End: Nine Highways Ready for Retirement - This year’s nominees include Austin’s Interstate 35, which exacerbated segregation in the urban core when it was built in 1962, replacing a once-vibrant boulevard that served as a community gathering space.

The Overlooked Biodiversity of Appalachian Caves – Many of these creatures would be on the list for Missouri caves as well!

A Bauhaus-Trained Artist Wove Tapestries in the Woods for Decades. Now, Her Legacy Comes into Focus – I enjoyed the art and the biography of the artist!

Unique Silla Kingdom Crown Was Decorated with Insect Wings – Found in South Korea in a 1,400-year-old grave…a gilt-bronze crown decorated with a series of heart-shaped indentations that had been delicately inlaid with the colorful wings of the jewel beetle, some of which remained in situ after almost a millennium and a half.

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.

Warming Linked to Rising Cancer Rates Among Women in the Middle East - As temperatures in the region rose, so did cancer rates in Qatar, Bahrain, Jordan, Saudi Arabia, the United Arab Emirates, and Syria, which are prone to extremely hot summers. Increasingly extreme heat is making air pollution worse, weakening our immune systems, and putting additional strain on hospitals. These and other factors could be driving up the risk of cancer.

90-Year-Old Korean Artist Kim Yun Shin Is Finally Going Global – Creative longevity!

Archaeologists Unearth Two Rare African Figurines in 1,500-Year-Old Christian Burials in Israel - The artifacts are carved from rare ebony wood that originated in India or Sri Lanka. Each figurine features a small hole through which a cord might have been threaded, allowing the owner to wear it around their neck.

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.

Fast food, fast impact: How fatty meals rapidly weaken our gut defenses - Researchers discovered the gut protective protein, IL-22, was rapidly depleted in mice after just two days of eating high-fat foods.

Where To Go Caving in the National Park System – Mammoth Cave, Carlsbad Caverns, Wind Cave, Crystal Cave in Sequoia, Jewel Cave, Lehman Caves in Great Basin. I have been to all of them except Crystal Cave and Lehman Caves. Mammoth Cave would be the closest for me to see again.

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.

Ten Little Celebrations – April 2025

April was a busy month….lots of little celebrations to choose from. My top ten are included in this post.

Lots of 300-piece puzzles. I found 23 300-piece puzzles at the used book sale and while I was sorting new donations. I’ll take a few of them each month when I go to Dallas to visit my dad so this will be a prolonged celebration.

Buying and planted spicebush. I celebrated finding spicebush at a native plant sale and bought two of them for my daughter’s yard. We got them planted the day after I bought them.

Another garden room. I savored my daughter’s garden room while ‘house sitting’ while she was at work and arborists were working in her yard.

Cherry cobbler. Cherry cobbler was one of my dad’s favorite desserts…and I celebrated that memory while realizing that it is one of mine too!

Hosta garden. I celebrated that the clumps of hostas in my flower beds were robust enough to divide and create a hosta garden between a pine tree and my patio that is too shady for other plants to grow well.

Clean windows. There was burst of spring cleaning at my house that involved windows! I haven’t done all of them yet but am celebrating the clear views from the ones that are clean.

Onondaga Cave. This is my favorite cave in Missouri (so far). I celebrated the day trip for the destination and that I did it with my daughter.

Tea Bar lunch. My daughter and I had one off-campus lunch after my geology class….to a place we had been to before. It was even better than our first lunch almost a year ago!

Edible violets. I celebrated learning that violets are edible. It is great to have native salad greens from my yard!

Car repair. I had an undercarriage cover that cracked near the front of my car. After thinking it was an easy fix (but it wasn’t) and the dealership ordering the wrong part, I celebrated finally getting it fixed.

Whorls of White off Greenland – A satellite image (from the Terra satellite), captured on February 24, 2025, shows the southern part of Greenland, from its snow-topped ice sheet and glaciers to the sea ice swirling along its coasts. When this image was acquired, the sea ice extent along Greenland’s East Coast was about average. However, Arctic-wide, sea ice in late February was exceptionally low for the time of year due to a warm winter.

The baby boom in seven charts - The US baby boom is typically defined as the time period between 1946 and 1964. But – it appears that the increase in birth rate began earlier…in the late 1930s. And it happened in many countries at the same time. This common trend across many countries suggests that the baby boom was driven by shared societal shifts rather than isolated national circumstances. The baby boom was also surprising because it happened alongside rising levels of women’s education and workforce participation — changes that now often coincide with falling birth rates.

Cheap Chinese Panels Sparking a Solar Boom in the Global South - A surge in solar installations in parts of the developing world. The glut of cheap solar means poorer countries can speed their shift away from fossil fuels while shoring up their supply of energy.

Following Frogs into the Flames – The tree frogs are using the trees all the way up to 40 feet, up to the crown of the tree, as a safe place during fires, and also for several weeks after the fire, when the ground is still somewhat inhospitable.

Brewing tea removes lead from water – Brewing black tea in cellulose tea bags works best for removing lead…longer steeping removes more.

Where California’s Land Is Sinking and Rising – Analysis of vertical land motion between 2015 and 2023. Areas of sinking land in coastal California cities and in parts of the Central Valley are caused by factors like soil compaction, erosion, and groundwater withdrawal.

Oldest Section of China’s Great Wall Uncovered - The recent excavations occurred around what is known as the Qi Wall, which was already considered to be the oldest in existence. New dating, however, suggests that the wall’s construction originates to the late Western Zhou Dynasty (ca. 1050–771 BC) and the Spring and Autumn Period (770–ca. 475 BC), making it 300 years older than previously thought.

What happens when a diet targets ultra-processed foods? - The findings suggest that people can reduce their ultra-processed food intake, if given the proper tools, and that they will be enthusiastic about interventions designed for this purpose. The results also suggest that reducing UPF intake will lead to meaningful health improvements -- such as weight loss and better mood -- in as short as eight weeks.

Glass fertilizer beads could be a sustained nutrient delivery system - Excessive and inefficient use of agricultural fertilizers can present an environmental threat, contaminating waterways and generating greenhouse gases such as nitrous oxide. Now, researchers have addressed those challenges with glass fertilizer beads. The beads control nutrient release….releasing fertilizer over a longer time period.

Historic Frank Lloyd Wright Home Gifted to Chicago University – The last remaining example of Wright’s prairie-style designs. When the Bach residence was completed in 1915, it boasted walnut furnishings throughout and a clear view of Lake Michigan from its rear porch.

Costco Adventures

My daughter decided to buy a Costco membership…and I decided to buy one too. I’ve had the membership for a month…am still in the learning curve. The warehouse is far enough away that I won’t be going more than about once a month; I’ll still do a weekly shopping at a grocery store very close to where I live.

My first trip to the warehouse was an adventure since their website does not say where in the warehouse things are located…or even accurately portrays what is in the warehouse versus has to be ordered. I did find a bedspread that I liked and a brand of protein drinks that was new to me but less expensive that the brand I had been buying (and nutritionally almost the same). They have bags of frozen chicken breasts that work great for us – but I might not even need one bag per month! I bought a big package of water bottles which I won’t do again – too heavy.

I was in the area and bought gas at Costco….saving a bit on each gallon. I’ll continue to do that, but it won’t be for every tank since I buy more gas when I am on a road trip…and generally do my driving around town under battery power (in my plug-in hybrid Prius Prime).

It snowed before my next trip to Costco and I decided to see if they sold a snow blower (probably for next winter). They had an electric one for a good price and, after my husband confirmed my initial assessment of the machine, I ordered it; it was delivered less than a week later.  It’s a relief to know that shoveling snow is not in my future!

For my third trip to Costco, I arrived as the warehouse opened and had a list. I was disappointed they did not have Ritz crackers (my husband eats a lot of them so I was hoping to get a large box) or a crunchy peanut butter that didn’t have sugar (also for my husband) or popcorn kernels (they had prepackaged popcorn….not the ‘whole food’ version). But – I did buy two sets of sheets, a 35 pack of Coke zero sugar (won’t do that again…too heavy), the CereVe lotion that I like, our favorite spaghetti sauce, frozen broccoli, a 2 loaf pack of Dave’s bread, 1.5 gallons of lactose-free milk (won’t do that again since my grocery store has it for a little bit more but in a recyclable container), mushrooms, protein drinks, and butter.

I am still in the mode of wandering around the store to find what I need….and occasionally splurging. The splurge of my most recent shopping was Honey Citron Ginger Tea. It is fabulous in hot water!

The lessons learned so far mostly are about not buying things that are too heavy. Big packs of toilet paper and paper towels are OK…but not soft drinks or water! I think I am getting what I expected from the membership so far, but will continue to assess as the year progresses.

Scientists Investigate Smell of Egyptian Mummies – A systematic study of the smells of 9 Ancient Egyptian mummified bodies. Odors are from pine, cedar, juniper, frankincense and myrrh.

'Healthy' vitamin B12 levels not enough to ward off neuro decline – The conclusion: “we need to invest in more research about the underlying biology of B12 insufficiency, since it may be a preventable cause of cognitive decline.”

Rethinking Fire-Resistant Landscaping: Which Trees Should We Plant? – After the recent wildfires across Southern California - Experts recommend replacing highly flammable trees with fire-resistant alternatives such as oak, sycamore, toyon, lemonade berry, and lilac. While the idea of removing iconic palm trees may be met with resistance, fire safety advocates argue that proactive changes in landscaping are necessary to adapt to the increasing wildfire risks in California.

Floods Swamp Tennessee – Satellite image from February 17 of the flooding after the February 15-16 storm. The area of western Kentucky to the north had more severe flooding….but clouds prevented a similar image on the 17th.

Learn COVID pandemic lessons — before it’s too late - “The science will deliver if we have a new emerging infectious disease,” says Joanne Liu, a pediatric emergency-medicine specialist at McGill University in Montreal, Canada, and a former international president of the medical-aid organization Médecins Sans Frontières (also known as Doctors Without Borders). “I think it will be the people who aren’t going to deliver…..None of us thought about the case scenario in which we would have leaders and a large part of the population that do not believe in science.” Yet that scenario is here. It means that researchers in public health and infectious diseases must work closely with social scientists who have been studying how another disease — misinformation — spreads and how best to counter it.

In many countries, people breathe the cleanest air in centuries. What can the rest of the world learn from this? – Lots of graphs….focused on sulfur dioxide and nitrogen oxide emissions….and the relationship to coal and catalytic converters.

The Science of Snakehead Slime - One of this fish’s most reported habits is its ability to move about on land. The answer, according to new research, may lie at least in part with another of the snakehead’s infamous features: its slime.

Wide-Eyed Fly Wins the 2024 Royal Entomological Society Photography Competition – Macro photography of insects…great work my amateur photographers. My favorite was the ladybird larva feeding on a colony of aphids.

How much protein do you really need to get strong? – A concerning take away: In 2018, a nonprofit group called the Clean Label Project, based in Broomfield, Colorado, released a report about toxins in popular brands of protein powders in the US. Researchers screened 134 products for 130 types of toxins and found that many protein powders contained heavy metals (lead, arsenic, cadmium and mercury), bisphenol-A (or BPA, which is used to manufacture plastic), pesticides, or other contaminants with links to cancer and other health conditions. Interestingly, one certified "organic" product had twice the contaminants of non-certified ones. Plant-based protein powders were the most contaminated, while egg and whey-based powders were found to be the cleanest.

Dust from Car Brakes More Harmful than Exhaust – Brake dust evidently causes greater injury to lung cells than diesel exhaust. Brake pads on the market now include copper which can aggravate asthma when inhaled. Note: the shift to electric vehicles could curb pollution from brake pads. Most electric cars use regenerative braking that limits the need for conventional brake pads.

Ten Little Celebrations – February 2025

February was busier than usual this year – a combination of a class, a new role for me in the Missouri Master Naturalist chapter, and some significant volunteer hours. It all made for plenty of little celebrations.

Owl Pellets. Having 28 children busily dissecting owl pellets – finding and identifying tiny bones. I celebrated that we picked something they all seemed to enjoy doing all the way to the end of our time (and a little beyond).

A new protein drink. Another whey-based protein drink that already has lactase added…worth celebrating for the convenience (and also because it is not as thick or expensive as the one I had been buying).

Niece going to have another baby. My sisters and I celebrated that there will be another baby in the family next fall. My sister that is the grandmother shared the news with us almost as soon as she found out.

Snowy Feeder Watch day. I celebrated the extra birds that came to our feeders when snow was on the ground.

Seeing lots of Northern Harriers. I celebrated seeing Northern Harriers on our field trip to Lockwood MO. We’d seen them before in New Mexico but not as many…and it’s thrilling to see them closer to where we live.

Lunch with my daughter. My daughter and I have been meeting for lunch a Student Union dining room after my geology class. It feels celebratory every time we meet (and we generally have dessert too).

Finding witch hazel. I celebrated when I found a witch hazel in bloom at the Springfield Botanical Garden…even though I was hoping to see more of them.

Grandniece and grandnephew. I celebrated seeing my sister’s grandchildren when I went to Dallas to visit my father. One is just learning to crawl, and the other is reasonably adept at recognizing/saying colors.

Snow day. A day of staying indoors due to weather – always a time to celebrate. The day seems like a serendipity block of time that I had not anticipated.

Soup. Soup is my favorite meal on cold days. I celebrated finding a quick and tasty one made from ingredients in my freezer: turkey meatballs, corn, broccoli, and edamame….a little seasoning and sometimes left over spaghetti sauce…delicious.

Frank Lloyd Wright’s Only Skyscraper to Be Sold for $1.4 Million After Legal Saga – Hopefully the power gets turned back on right away and the conservation of the building starts.

Under Colonial-Era Barracks Floorboards in Australia – Peanut shells, peach pits, citrus peel, hazelnuts….hiding the remains of treats from the authorities.

Experts Are Unraveling the Mysteries of This Breathtaking 2,000-Year-Old Mosaic Depicting Alexander the Great in Battle – The mosaic comes from the ruins of Pompeii and was discovered in 1831. It is housed in the National Archaeological Museum of Naples. Conservation work started in 2020. The mosaics tesserae rocks could have come from Italy, Greece, the Iberian Peninsula and Tunisia.

Mt. Washington Cog Railway Goes Electric! - Engineering students from the University of New Hampshire are working alongside the Mt. Washington rail staff to develop an all-electric locomotive, with help from robotic welding systems. It will be the world’s first entirely battery-powered mountain-climbing electric vehicle.

As Oceans Warm, Predators Are Falling Out of Sync with Their Prey - Warning signs are beginning to be observed in marine ecosystems planetwide, from herring and zooplankton in the North Sea, to sardines and bottlenosed dolphins in the Southern Ocean, to — along with striped bass — baleen whales and menhaden in the northwest Atlantic.

Meet the Channel-billed Cuckoo, the World’s Largest Brood Parasite - They’re the size of a raptor, with broad wings, a long, trailing tail, and a honking great bill reminiscent of hornbills or toucanets. Their plumage is a light grey, with thick black and white banding on the tail feathers. And their eyes: large, beady, blood-red, surrounded by a strawberry-colored ring of bare skin.   

Noise as a Public Health Hazard - Cities in Europe and the United States are starting to map noise levels to understand where dangerous sound levels exist and how to better protect people living and working nearby.

Atop the Oregon Cascades, team finds a huge, buried aquifer - Scientists have mapped the amount of water stored beneath volcanic rocks at the crest of the central Oregon Cascades and found an aquifer many times larger than previously estimated -- at least 81 cubic kilometers. The finding has implications for the way scientists and policymakers think about water in the region -- an increasingly urgent issue across the Western United States as climate change reduces snowpack, intensifies drought and strains limited resources.

Carbon Dioxide Levels Rose by a Record Amount Last Year - Last year saw the biggest one-year jump on record for the past 60 years, with carbon dioxide levels rising by 3.58 parts per million. Increasingly severe heat and drought mean that trees and grasses are drawing down less carbon dioxide than in the past, while desiccated soils are also releasing more carbon back into the atmosphere. Conditions were particularly poor last year owing to a very warm El Niño which fueled hotter, drier weather across much of the tropics. The forecast is for a smaller jump in carbon dioxide levels in the coming year because the Pacific is now in the La Niña phase.

Floods linked to rise in US deaths from several major causes - Over the last 20 years, large floods were associated with up to 24.9 percent higher death rates from major mortality causes in the U.S. compared to normal conditions. A new study demonstrates the sweeping and hidden effects of floods --including floods unrelated to hurricanes, such as those due to heavy rain, snowmelt, or ice jams.

Frozen Cranberries

The cranberries I froze back in November and December are enhancing my winter meals. I like the flavor and color they add! Here are a few of my recent cranberry additions…

I processed frozen cranberries into bits to fold into oatmeal cookies; I liked the tang of the cranberries as a change from raisins. My husband surprised me by liking them as well since he usually says he wants plain oatmeal cookies – no raisins or nuts.

Cranberries also are great in spicy soups. The one I have enjoyed most recently was one I made with left over taco meat. I cooked arugula and cranberries before adding the left-over meat. The cranberries split as they cook…and can we squished…no need to process them beforehand.

Cranberries are always good with any chicken or turkey dish…probably because of the priming from Thanksgiving meals over the years.

…. I am savoring the supply I still have in the freezer.

Making Hot Chocolate

It’s a cold morning as I write this, and I have just made myself a cup of hot chocolate…a great way to start the day.

I start out with water (about 25% of my cup)…microwave it for 30 seconds…then add a rounded teaspoon of cocoa powder. I enjoy watching the powder melt! The clumps are like little melting icebergs that eventually disappear under the surface.

Then I add milk (about 50% of my cup) and then more water (another 25% of my cup). Most of the time I also add a very light sprinkle of cayenne pepper too – a nod to the way Aztecs made their chocolate drink although they didn’t use milk, and they made their drink at room temperature.

The cup goes back in the microwave for 2.5 minutes.

I’ve gotten used to not adding any sugar at all! I like the flavor with just the milk and cocoa and cayenne. On cold mornings, it is the first calories of the day…but not as many as the traditional hot chocolate or hot chocolate mix packets.

Gleanings of the Week Ending December 14, 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.

Unusual Foods People Used to Eat All the Time – Poke (as in pokeweed) salad, turtle soup, cream chipped beef on toast, limburger sandwich, and vinegar pie. I remember my mother serving cream chipped beef on toast in the 1960s. She also served canned chicken or hard-boiled eggs in cream sauce over toast! It was a quick meal in the days before microwaves.

Incredible Winners of the 2024 International Landscape Photographer of the Year – Take a look and pick a favorite. I like the ‘sunrise on the Atacama Desert’….its crisp lines. The lightning and double rainbow over the Grand Canyons is awesome too.

The ancient significance of the date palm - Phonecia translates to the “Land of Palms” in ancient lands, where palm growth and harvesting dates to approximately 5,000 years ago in ancient Mesopotamia, growing along the Tigris and Euphrates rivers. Date palm trunks and fronds were used as the roof for homes of Akkadians, Sumerians, and Babylonians. Mature palm leaves were made into mats, baskets, screens, and fans.

'One of the greatest conservation success stories': The 1969 mission to save Vermont's wild turkey - Vermont's wild turkeys are a successful restoration story, and one that stood the test of time, unlike elsewhere in the United States where wild turkey numbers are now declining.

Here's how much home prices have risen since 1950 – I bought my first home in 1978…bought subsequent homes in 1983, 1986, 1994, and 2022. I remember the interest rates on mortgages in the 1980s being high (the article says 13.7%) and 1990s (the article says 10.1%). In 2020 the interest rate was low, but we didn’t need a mortgage to purchase our last house! Every house we’ve purchased over the years has been above the median home price (unadjusted).

VA offering 'green burial sections' at national cemeteries – Hopefully ‘green burial’ will become the norm everywhere soon. We don’t need chemicals/embalming fluids leaching into the environment.

When Did People Start Eating Three Meals a Day? - In ancient Roman times, dinner was the one large meal everyone ate, although it was consumed earlier in the day than it is today — sometime around noon. This extended into the Middle Ages in Europe. Laborers often ate a small meal of bread and ale early in the morning before starting a day’s work on the farm. Their main meal of the day, called dinner, was served around noon, and a light snack, known as supper. By the end of the 18th century, many people were eating dinner in the evening after returning home from work. It wasn’t until around 1850 that lunch officially began filling the gap between breakfast and dinner. By the turn of the 20th century, lunch had become a defined meal, typically eaten between 12 p.m. and 2 p.m., and consisting of standard lunch fare even by today’s standards: sandwiches, soups, and salads.

Can we avert the looming food crisis of climate change? - The study integrates key concepts of the dynamics of atmospheric CO2, rising temperatures, human population, and crop yield…and highlights the urgent need to address CO2 emissions to maintain agricultural productivity. It also uncovers a promising strategy to mitigate crop loss caused by climate change: developing crop varieties with a higher temperature tolerance. Next steps for the team involve refining their model to include more variables like insect population, water availability, soil quality, and nutrient levels, which also impact crop yield under climate change.

US Grid Operators Kept the Lights on This Summer with More Solar, Storage, & Wind - In summer 2024, grid operators in all regions maintained enough capacity to keep the lights on during periods of peak demand, even as they retired older generators, and an increasing number of regions used more solar and storage to meet peak demand. Because it is one of the nation’s fastest-growing regions and had near-record peak demand in 2024, the new report concentrates on ERCOT (Electric Reliability Council of Texas) to analyze summer grid operations.

Old Growth – Mitch Epstein photographs of very old trees.

The true story of a famed librarian and the secret she guarded closely – Belle da Costa Greene, the first director of New York's historic Morgan Library and Museum.

Inside Turkey’s Mysterious Ancient City That Once Sheltered Thousands—Underground - The Derinkuyu underground city is a sort of gargantuan anthill, except made by and for humans—up to 20,000 of them at a time, in fact. The city descends 280 feet into the earth, divided into eight levels. Upper levels were primarily used for living and sleeping, while lower levels were used for storage, even housing a dungeon. The far-stretched system of interconnected rooms was carved out of the Cappadocia region’s tuff rock. People didn’t live in these underground quarters year-round, however, as they were mainly used for shelter during times of conflict or extreme weather.

Climate change will affect food production, but here are the things we can do to adapt - Farmers can pick crop varieties best suited to different climate condition...production can shift to places with more optimal temperatures…planting and harvest times can shift as the seasons shift…focusing on the right irrigation, fertilizer, pesticides synchronized to climate change. We have the chance to build a more productive and resilient food system, but it’s not guaranteed that we will. It depends on whether the seeds, irrigation, and adaptation practices will be available. That will require real and sustained investment from governments, donors, and private companies.

Toothbrushes and showerheads covered in viruses ‘unlike anything we’ve seen before’ - We live in a richly microbial world. Interactions with bacteria and other microbes in our homes are an integral part of our human biology.

The monarch butterfly may not be endangered, but its migration is - Migrating monarchs don't fly at night, so they spend their evenings in bunches on trees or shrubs, known as roosts. The study relied on 17 years of data from more than 2,600 citizen scientist observations of monarch roosts along the butterfly's migration route. The researchers found that roost sizes have declined by as much as 80%, with these losses increasing from north to south along the migration route. The evidence shows that when monarchs are reared in a captive environment, either indoors or outdoors, they're not as good at migrating.

World’s Rivers Are Driest They - In 2023, the hottest year on record, the Mississippi River and Amazon River basins were at all-time lows, while the Ganges, Brahmaputra, and Mekong rivers, which all have their headwaters in the Himalayas, were also unusually dry. Across nearly half the globe, rivers were drier than normal.

The worrying puzzle behind the rise in early-onset cancer - Over the past 10 years, rates of colorectal cancer among 25- to 49-year-olds have increased in 24 different countries, including the UK, US, France, Australia, Canada, Norway and Argentina. Perhaps the most obvious explanation points to the role of obesity and metabolic syndrome, conditions which have been associated with driving cancer risk through increasing inflammation throughout the body and causing the dysregulation of key hormonal pathways. Or maybe changes in sleep patterns is part of the explanation. Combined with shifts in lifestyle, many cancer scientists believe that a key driving force for these illnesses is the consequences of various toxic changes within the gut (from microplastics). Antibiotics might be involved too. The bottom line…it’s a looming public health crisis.

New research reveals how large-scale adoption of electric vehicles can improve air quality and human health - Computer simulations show that aggressive electrification of the U.S. vehicle fleet, coupled with an ambitious rollout of renewable electricity generation, could result in health benefits worth between US$84 billion and 188 billion by 2050. Even scenarios with less aggressive grid decarbonization mostly predicted health benefits running into the tens of billions of dollars.

New study explores how universities can improve student well-being - Six guiding principles for improving student well-being:

  • Embedding well-being into curricula for broader, more accessible adoption.

  • Having each initiative only focus on one or two aspects of well-being, making it easier to create instruction that can also be more immersive.

  • Tailoring initiatives to the student body and university culture.

  • Securing buy-in from faculty.

  • Ensuring new offerings are accessible and don't create additional financial burden for students.

  • Employing an iterative assessment framework at the beginning to make it easier to change or scale up a program.

Ten Little Celebrations – October 2024

The temperatures were more pleasant in October….I enjoyed the outdoor field trips and classes a lot more.

Pleasant temperature to walk around the Missouri campus during class. We were outdoors longer but it was easy compared to short hikes around campus in August and September!

Field trip to a healthy stream and woodland. Celebrating the water quality and the native species (not overcome by invasives)!

Cut down a Japanese barberry and burned most of it. Celebrated one more non-native (that is sometimes invasive) being gone from my yard.

Geology field trip plans. I celebrated that enough of my Missouri Master Naturalist classmates and chapter are interested in geology field trips to make them a likely late fall/early winter activity.

Getting seeds planted. I got buckeye, Hopi sunflower, common milkweed, and persimmon seeds during the second week of October….and celebrated when I got them planted. Some must go through the cold temps of winter to sprout in the spring.

Volunteering at a fair for homeschoolers…talking about Monarch butterflies. I celebrated by first gig as a Missouri Master Naturalist…and that my iPad-based slideshow of Monarch butterfly pictures was well received.

Owl Pellet. I vaguely remember that I had dissected an owl pellet in some previous training…but I celebrated that I did a more thorough job this time… and found a complete rodent skull…and the backbone…lots of ribs.

First solo Missouri Master Naturalist volunteer gig. I celebrated that the two days spent doing an after-school program with a local school for gift students was positive for them…and for me!

Whataburger. Sometimes I just want to splurge. On the way back from my Dallas trip, I stopped for a Whataburger…celebrated that it tasted just as I remembered - although I won’t do it very often.

Successfully completed my Missouri Master Naturalist training. Hurray! I am celebrating what I learned and that I now have more time to volunteer!

American Agriculture in the early 1990s (ebooks)

Liberty Hyde Bailey edited 4 volumes of the Cyclopedia of American Agriculture between 1900 and 1910. It was a time when horticulture and agriculture were becoming more organized at universities and Bailey was a proponent of America as a ‘great agricultural civilization.’

The books are easily browsed on Internet Archive and the photographs clearly reflect the ‘state of the art for agriculture’ in the early 1900s when they were written. I selected two sample images from each of the 4 volumes. (click on the image to see a larger version)

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.

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.

Chickasaw National Recreation Area's Monkey Tree Needs Some TLC - An Osage orange tree estimated to be about 130 years old with three thick spreading trunks that generations of children have played on.

Divers Discover Mesmerizing Roman Mosaic Beneath the Sea – Near Naples…a villa in a city known as the Las Vegas of the Roman Empire…now under water.

Healthy diet with less sugar is linked to younger biological age – The correlations between a diet that is rich in vitamins and minerals, especially one without much added sugar, and having a younger biological age at the cellular level.

Agriculture: Less productive yet more stable pastures - Grassland optimized for high yield responds much more sensitively to periods of drought than less intensively used meadows and pastures.

Anne Boleyn’s Childhood Home Is Restored to Its Tudor Glory – The interiors of rooms restored to the style they had during Anne Boleyn’s time.

Forest carbon storage has declined across much of the Western U.S., likely due to drought and fire – Forests in some parts of the world, like the American West, probably do not have the potential to help curb climate change.

Ten Little Celebrations – July 2024

4th of July. The holiday was full of the poignancy of the First Americans Museum and the Oklahoma City National Memorial (site of the Murrah Building bombing)…and then fireworks observed from our hotel window. It is probably going to be one of the most memorable 4th of July celebrations for me.

 A neighborhood walk before the rain. There is always something to notice on a walk around our neighborhood…I celebrate our robins and dandelion puffs and magnolias in bloom…relatively common things that brighten my day.

A protein drink that already has lactase enzyme in it. I was pleasantly surprised that the protein drink that I can find easily at the truck stops along the way to Dallas includes lactase so that I don’t have to remember to take a Lactaid….and it tastes good. Celebrating!

 Philbrook Museum and Gardens.Celebrating finding a ‘favorite place’ in Tulsa.

 Planting orange daylilies. I ordered 25 daylily roots and planted them around the two maples in my front yard. I am celebrating that maybe I can reproduce the ruff I had around my oak tree in Maryland.

 A robin’s egg. Celebrating finding an eggshell…and realizing – from the color – that it was a robin’s egg.

Springfield Botanical Gardens daylilies and pollinator gardens. Celebrating one of my favorite places in Springfield. There is always something worth seeing there.

Out to lunch with my daughter. My daughter and I are exploring locally owned restaurants for brunch or lunch. All of them have been good experiences….celebrating my daughter and the food.

Friends of the Library. Celebrating my first volunteer gigs in Missouri. I got some additional training this month so I can do more tasks. I enjoy the work and the other volunteers.

Whatever it is, the way you tell your story online can make all the difference.
