Gleanings of the Week Ending December 13, 2025
/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.
How extreme weather is making plastic pollution more mobile, more persistent and more hazardous - Rising temperatures, humidity and sunlight break plastic down, making it brittle and cracked, accelerating its disintegration into tiny fragments. A 10-degree Celsius (18 Fahrenheit) rise in temperature during an extreme heat wave could double the rate at which plastic degrades. Extreme storms, flooding and wind also hasten the breakdown of plastic, mobilize it and spread it more widely. Flooding can also help forge “plastic rocks,” created when rocks and plastics form a chemical bond and merge together. These become hotspots for microplastic generation. Wildfires release microplastics and highly toxic compounds into the atmosphere. Global annual production of plastic increased 200-fold between 1950 and 2023 and is predicted to keep increasing as the world moves toward clean energy and oil companies shift investments to plastics.
YMCA: The Swan Song of SROs and the Birth of Modern Homelessness - Single room occupancy hotels played a central role in America’s affordable housing ecosystem for decades, providing cheap, flexible accommodations without government subsidy. They are effectively large-scale boarding houses, offering small private rooms or dorm-style quarters with shared bathrooms and minimal kitchen facilities. The YMCA was the nation’s largest SRO provider, with more than 100,000 units nationwide at its peak. SROs were far from ideal, but without this form of housing or any other low-cost option, homelessness was the inevitable result. It was just as Edith Elmer Wood feared back in 1919: Housing reform had created a housing famine.
Recycling Lead-Acid Batteries Has Significant Health Risks - What happens to the old ones when they are no longer serviceable? They get melted down to recover the lead in them, which can then be used to make new batteries. In the US, that work often gets outsourced to other countries. It’s a patchwork of shoddy factories in places like Ghana, Nigeria and Tanzania providing more lead for new car batteries….and where people die from lead poisoning. Car companies look the other way.
More Than 1,200 Marine Animal Species Eat Plastic. Ingesting Even a Tiny Amount Can Kill Them - Data from more than 10,000 marine animal autopsies. About half of the examined sea turtles, one-third of seabirds and one in eight marine mammals had plastics in their stomachs. The study didn’t examine other ways plastics can hurt wildlife, such as strangulation, malnutrition or toxic effects. It also didn’t look at the harms of tinier pieces of plastics—microplastics—which have been found in the deep ocean and can also affect marine life. Researchers say the best way to protect wildlife from plastic is to reduce the amount of it that enters the ocean, namely through local and national policy.
The Forgotten Roman Ruins of the ‘Pompeii of the Middle East’ – Jerash – ruins near Amman, the capital of Jordan and the country’s second most popular tourist destination after Petra. After spending more than a millennium covered by sand, Jerash has reclaimed its place as a cornerstone of both Western and Middle Eastern civilization.
Just ten species make up almost half the weight of all wild mammals on Earth – Deer and boars account for almost half the biomass of wild land animals.
New research reveals what’s really hiding in bottled water - Each sip may contain invisible microplastics that can slip through the body’s defenses and lodge in vital organs. These tiny pollutants are linked to inflammation, hormonal disruption, and even neurological damage, yet remain dangerously understudied. “People need to understand that the issue is not acute toxicity -- it is chronic toxicity.”
Beavers are Dam Good for Biodiversity, Bringing Bats, Butterflies and Other Critters to Their Neighborhoods - Beavers are famous for being ecosystem engineers, capable of transforming once-dry landscapes into lush, green wetlands that support many other land- and water-dwelling species. Now, two new studies suggest these benefits also extend to creatures who spend much of their time in the air like bats and pollinator insects.
This tiny pill could change how we diagnose gut health - Tiny ingestible spheres filled with engineered bacteria can detect intestinal bleeding by glowing when they encounter heme. Early tests in mice suggest they could become a quick, noninvasive way to monitor gut disease. The work was done by the NSF of China and other sources in China. Will China now dominate this type of research with the funding cuts in the US?
Meet the 7 Swans a-Swimming – There are 7 swan species in the world…which fits very well with The Twelve Days of Christmas.
