10 Ways Vincent Van Gogh Continues to Make News, Even Today – An artist that has been ‘newsworthy’ for a very long time. This post about recent instances of ‘Van Gogh mania.’

Measles vaccines save millions of lives each year – Statistics about measles and the impact of the vaccine…history and how the choices we make will have impacts on the future trajectory of the disease.

New River Gorge National Park and Preserve – It became a national park in 2020. I’ve driven through it…stopped at a visitor center…but haven’t experienced it the way I have other national parks.

Forty Years of Change in Louisiana’s Wetlands – Images from Landsat 9 from 1985 and 2024 show that much of the wetland has transitioned to open water….reshaped by storms and sea level rise.

In healthy aging, carb quality counts - The researchers analyzed data from Nurses' Health Study questionnaires collected every four years between 1984 and 2016 to examine the midlife diets and eventual health outcomes of more than 47,000 women who were between the ages of 70 and 93 in 2016. The analysis showed intakes of total carbohydrates, high-quality carbohydrates from whole grains, fruits, vegetables, and legumes, and total dietary fiber in midlife were linked to 6 to 37% greater likelihood of healthy aging and several areas of positive mental and physical health.

Wildlife Photographer Captures Mid-Air Battle of Two Birds Fighting for Dinner – The battle over a vole between a Northern Harrier and Short-eared Owl in British Columbia, Canada. Dramatic photos. Both birds are over Missouri Prairies in the winter too!

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

China’s Mega Dam Project Poses Big Risks for Asia’s Grand Canyon - China’s plans to build a massive hydro project in Tibet have sparked fears about the environmental impacts on the world’s longest and deepest canyon. It has also alarmed neighboring India, which fears that China could hold back or even weaponize river water it depends on.

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

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

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.

Emily Cole, Daughter of Hudson River School Icon, Shines in Overdue Museum Show – She became a porcelain painter (botanicals) and painted in her father’s studio…. exhibiting her work a what is now the Thomas Cole National Historic Site.

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.

The Largest Harbor in Ancient Greece Is Centuries Older Than We Thought - A discovery of lead pollution and 5 lumps of brown coals were carbon dated to the days of the Bronze Age.

When This Brilliant Author Died, She Left Behind a Legacy of Grief, Haunting Poetry and Surprising Resilience – I remember reading Silvia Plath books as a teenager.

Maple seeds’ unique spinning motion allows them to travel far even in the rain, a new study shows – Autorotation keeps the seeds in the air for longer, so they travel farther. The researchers studied how raindrops that hit the seeds reduce the time they are in the air. The next part of the study will look at rolling samaras (from tulip poplar and ash trees).

Rare Footage Shows Baby Polar Bears Emerging from Their Den in the Arctic - At birth, polar bears are blind, nearly hairless and weigh just over a pound—about the same as a loaf of bread. But they spend their first few months snuggled inside a snowy den, fattening up on their mother’s milk. By the time they emerge in the spring, the cubs are covered in fluffy white fur and weigh 22 to 26 pounds. Scientists have managed to capture rare footage of a polar bear mother and her cubs leaving their den in the Arctic for the first time.

Summer Heat Wave in South America - In February 2025, an area of high pressure parked over the southern Atlantic Ocean, causing temperatures to soar in parts of South America. As of February 27, Argentina noted that six provinces were under a red-level (very dangerous) alert for extreme heat.

The world's strongest ocean current should be getting faster – instead, it is at risk of failing – The Antarctic Circumpolar Current - five times stronger than the Gulf Stream and more than 100 times stronger than the Amazon River. Fresh, cool water from melting Antarctic ice is diluting the salty water of the ocean, potentially disrupting the vital ocean current.

More Than 1,500 Sandhill Cranes Killed by Bird Flu in Indiana - In recent weeks, biologists with the Indiana Department of Natural Resources have counted hundreds of dead sandhill cranes statewide. At least 500 of the birds were found dead in Jackson County, in the south-central part of the state, in early January. So far, no sick or dead cranes have been reported in Nebraska.

Inside the Clear Waters of England’s Ancient Chalk Streams - A globally rare type of waterway found almost exclusively in England—these rivers’ specific features both create rare biodiverse habitats and make them uniquely vulnerable. Burbling up from aquifers formed in chalk layers that date back to the Cretaceous Period, these rivers exist only where chalk sits close to the Earth’s surface. That’s why of the 200-odd identified chalk streams in the world, nearly all of them are found in England, where 66 million years ago a shallow seabed collected the skeletons of aquatic creatures—the makings of chalk. Ideal habitat for trout and Atlantic salmon.

How our lungs back up the bone marrow to make our blood - Researchers at UCSF found hematopoietic stem cells (HSCs) in human lung tissue that make red blood cells, as well as megakaryocytes, which produce the platelets that form blood clots.

Gold Jewelry Found at Karnak Temple - Karnak was the largest and one of the most important religious sites in ancient Egypt. An Egyptian-French team was investigating the northwest sector of the precinct when they uncovered a ceramic vessel that contained a collection of gold jewelry and statuettes dating to the 26th Dynasty (664–526 b.c.). One of the statuettes depicts the Theban triad of gods: Amun, his wife Mut, and their son Khonsu. Archaeologists also discovered several mudbrick buildings dating to the same era that were likely used as workshops or storage facilities connected to the Karnak temples.

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.

Cold is beneficial for healthy aging, at least in animals – Research with nematodes and cultivated human cells. Both carried genes for ALS and Huntington’s disease. Cold actively removed protein clumps…preventing protein aggregation that is pathological for those diseases. The protease activator that caused the change was discovered…and the impact of temperature explored. Interestingly – “human body temperature has steadily declined by 0.03 degrees Celsius per decade since the Industrial Revolution, suggesting a possible link to the progressive increase in human life expectancy over the last 160 years.”

See Colorful Paintings of the Zodiac Signs from an Ancient Egyptian Temple – Ceiling paintings in a Ptolemaic temple…suggesting Greeks brought the zodiac tradition to Egypt.

 Nearly 1,000 Acres Added to New River Gorge National Park and Preserve – The acres are in the Preserve part of the park. I have visited the park only once…passing through on one of my many trips between Maryland and Missouri. There is a lot to explore there!

Vehicle Exhaust Filters Do Not Remove “Ultrafine” Pollution – Aargh! No wonder there are so many yellow and red air quality days in our cities caused by particulates.

What it really takes for Asia to get to net zero – Home to 5 of the 10 largest emitters: China, India, Indonesia, Japan, and South Korea. An article posted ahead of the BBC’s Sustainability Summit in Singapore. "The perception of higher cost for sustainability practices remains," says An (chief sustainability officer of City Developments Limited in Singapore). "But companies are starting to wake up to the fact that achieving climate goals is an "investment, not a cost."

Thread-like pumps can be woven into clothes – My first thought was maybe these will be commonplace in clothes – enabling us to work outdoors even on very hot days.

Sabertooth cat skull newly discovered in Iowa reveals details about this Ice Age predator – Almost as iconic as dinosaurs when it comes to childhood curiosity about extinct animals. One piece of trivia about modern cats: 40% of lion skulls in a study had survived head trauma to hunt another day. One of the ‘sabers’ of the Iowa Sabertooth was broken not that long before it died…might have even caused its death. Prey fights back…the predator does not always ‘win.’

Europe's unique trials in food 'social security' – Two projects: Montpellier, France and Brussels, Belgium. Run by collectives. The idea that quality, nutritious and organic food should be accessible to everyone.  Each citizen receives a monthly allowance enabling them to buy food meeting certain environmental and ethical criteria. The trials are running for 12 months. The big challenge is changing the way society thinks about food.

The Beauty of Bugs – The picture at the beginning of the article jogged my memory – of the necklace made from insect exoskeletons I saw at the Edge of Cedars State Park Museum when I visited Utah in 2013! I posted about it and took a picture back then…and am pleased to learn more about it and the possible implication it might have re the Basketmaker II culture.

Scientists discover a way Earth’s atmosphere cleans itself – It’s surprising that we don’t know more about how the Earth’s atmosphere works!

Virginia Museum of Fine Arts – Part 2

Continuing the highlights from our visit to the Virginial Museum of Fine Arts….

The Ancient gallery is dedicated to Egyptian, Greek, Roman and Etruscan art. I was glad the museum permits (non-flash) photography because there were lots of Zentangle prompts in the pots. Thinking about how old some of them are…how amazing it is that they survived…that they still appeal to us now. Some of them appeared to be more functional objects than art but may those pieces tell us more about the lives of long-ago peoples that things intended only for display or another special purpose.

I’d never seen an Egyptian bust that was intentionally made from a rock with a vein of another color across the face. It is quite striking and was the ‘style’ for a short period of Egyptian history.

In the East Asian gallery, there was black screen with botanical images. It did not look as impressive until I zoomed with the camera and made out the detail of the images.

Other items from the East Asian gallery provided a diversity of styles and materials. The small bowl is made from agate.

Back for a last look as some pieces from the Ancient gallery….gold piece from a crown, more pottery, jewelry and two small friezes.

For a short walk around, we saw a lot of interesting (and beautiful) things!
