Fall 2025 International Student Enrollment Outlook and Economic Impact – The drop in new international student enrollment in the United States this fall could result in a 15 percent drop in overall enrollment. This drop would result in nearly $7 billion in lost revenue and more than 60,000 fewer jobs.

Woodpeckers thrive where missiles fly. How a bombing range became a wildlife refuge - A U.S. Air Force bombing range in Florida has become a sanctuary for endangered species like the red-cockaded woodpecker!

Used EV Batteries Get New Life Supporting the Texas Power Grid - In Texas, retired EV batteries are being repurposed to shore up the state’s unstable electric grid. Batteries have made significant capacity contributions within Texas’ electric grid in recent years and have been credited with helping prevent summer blackouts by bolstering grid reliability.

World Cannot Recycle Its Way Out of Plastics Crisis - The world churns out more than 200 times as much plastic today as it did in 1950, and production is only rising. Microscopic bits of plastic waste have been found nearly everywhere. Many of the more than 16,000 chemicals used in plastics — flame retardants, fillers, dyes — can harm human health, and fetuses, infants, and young children are particularly vulnerable. Without efforts to stem the use of plastic, production is on track to nearly triple by 2060.

Gorgeous, Hidden Animal Tattoos Discovered on a More Than 2,000-Year-Old ‘Ice Mummy’ by Using Digital Imaging - Tigers, stags and a leopard twist around each other, the animals’ stylized and intricate details spread in ink across a woman’s forearm. On her hand is the delicate outline of a bird with a fluffy tail. It sounds like something you might see from a tattoo artist today, but these designs appear to be preserved on a more than 2,000-year-old “ice mummy” from Siberia’s Pazyryk culture.

How do the microplastics in our bodies affect our health? - The use of plastics in society first came into being on a large scale in about the 1920s, and we see a big increase from the 1960s onwards. In a study published in 2024, scientists found that consumption of the particles has increased sixfold since 1990, particularly in various global hotspots including the US, China, parts of the Middle East, North Africa and Scandinavia. In February 2025, scientists identified microplastics in the brains of human cadavers. Most notably, those who had been diagnosed with dementia prior to their death had up to 10 times as much plastic in their brains compared to those without the condition. Because humans are consuming so many different types of plastic, it's both unlikely and impractical, without vast sources of funding, for researchers to be able to identify a direct link between ingesting microplastics and one particular disease….but there is mounting evidence that they are impacting health.

This diet helped people lose twice as much weight, without eating less - People eating minimally processed foods lost twice as much weight as those on ultra-processed diets, even though both diets were nutritionally balanced and participants could eat freely!

A Promised U.S. Drilling Boom Has Yet to Materialize - The price of oil, the world’s most-traded commodity, is more responsive to global demand and supply dynamics than to domestic policy and politics. The economics of solar and wind are increasingly too attractive to ignore. They are now almost always the least expensive — and the fastest — option for new electricity generation.

Your sleep schedule could be making you sick, says massive new study - A global study of over 88,000 adults reveals that poor sleep habits—like going to bed inconsistently or having disrupted circadian rhythms—are tied to dramatically higher risks for dozens of diseases, including liver cirrhosis and gangrene.

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

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

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

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

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

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

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

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

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

Goodbye to the Wheelbarrow

We made the decision to not move our wheelbarrow to Missouri over a month ago. It was rusting and the tire had never managed the heavier loads very well. We took it to scrap metal collection at our county landfill after we finished using it for the yard work and moving other items headed for trash/recycling from the basement around to the front of the house.  

The wheelbarrow was a legacy from my mother-in-law…one of the items that continued to remind me of her through the over 30 years since her death. I don’t remember her buying it during the year or so she lived with us, so it must have been something she moved from Texas to Maryland. She did a lot of gardening that year, but it seems improbable that she could handle the wheelbarrow physically. We still have miniature daffodils and day lilies in our yard from the bulbs she bought/planted; I moved them with us from our previous house. I’ve decided not to dig up bulbs to take to Missouri…concerned about introducing some invasive insect or worm that is common in Maryland but not in Missouri. I’m going to buy some new bulbs next fall and when they bloom – I’ll still be reminded of her.
