Gleanings of the Week Ending November 29, 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.

Everyday microplastics could be fueling heart disease - Microplastics—tiny particles now found in food, water, air, and even human tissues—may directly accelerate artery-clogging disease, and new research shows the danger may be far greater for males.

The Mystery of the Mast Year - Every few years, certain species of trees seem to go buck wild, dropping an extraordinary quantity of nuts, seeds, or fruits all at once. What’s more, this bumper crop tends to extend across vast geographical ranges, so that a white oak in Central Park is shedding buckets of acorns at the same time as a white oak in the Shenandoah Valley. Not all trees mast, but many species dominant in American forests do, such as oak, hickory, beech, and dogwood.

Ultra-processed foods quietly push young adults toward prediabetes - More than half of the calories people consume in the United States come from ultra-processed foods (UPFs), which include items such as fast food and packaged snacks that tend to contain large amounts of sodium, added sugars and unhealthy fats.

Why Should We Avoid Heating Plastic? - When plastic is heated, its molecules will move around more freely and the whole structure will become less rigid. This makes it easier for those additives to detach and migrate into nearby foods or liquids. To reduce your exposure, heat food in containers made of inert materials like ceramic or glass, avoid storing hot, fatty, or acidic food in plastic, and try to shorten the storage time of all food and beverages in plastic containers.

'They're just so much further ahead': How China won the world's EV battery race - In 2005, China only had two EV battery manufacturers. Twenty years later, it produces more than three-quarters of the world's lithium-ion cells. Today, China dominates the production at every stage of the battery supply chain, apart from the mining and processing of some raw minerals.

Obesity-Related Cancers Are Rising in Young and Old - Six of cancers—leukemia, thyroid, breast, colorectal, kidney, and endometrial—increased in prevalence in young adults in at least 75 percent of the examined countries. However, five of these six cancers also showed increased prevalence in older adults. Colorectal cancer was the exception. The cancer types with increased incidence in both younger and older adults were all linked to obesity.

Growth of Wind and Solar Keeping Fossil Power in Check - This year it is projected that new wind and solar power will more than meet growing demand for electricity globally, keeping fossil fuel consumption flat. However, while the world is beginning to keep emissions from power plants in check, overall emissions continue to tick up, rising by 1.1 percent this year.

Researchers Discover ‘Death Ball’ Sponge and Dozens of Other Bizarre Deep-Sea Creatures in the Southern Ocean - Researchers have discovered 30 previously unknown deep-sea species in the remote ocean surrounding Antarctica - an achievement highlighting just how little humanity knows about some of the deepest regions of the planet. Fewer than 30 percent of the expedition’s samples have been assessed thus far so there could be more discoveries to report soon.

Short-Chain PFAS Eclipse Their Longer Counterparts in Blood Serum - The conventional wisdom is that short-chain PFAS are of lesser concern because they don’t bioaccumulate, but what we’re seeing is that they can occur at high levels in people. A new study shows that young adults who ate more UPFs also showed signs of insulin resistance, a condition in which the body becomes less efficient at using insulin to manage blood sugar.

Get Up Close with Alabama’s Rivers – Mac Stone photographing Alabama’s waterways…places full of biodiversity. The post includes pictures: southern dusky salamander, pitcher plant blooms, alligator snapping turtles, swamp lily, brown pelican.

Vacation to Pensacola, FL

Our trip from home (Nixa, MO) to Pensacola, FL in April was our most substantial post-pandemic vacation…three days in a place we had not visited before bracketed by long driving days. We thought we were used to long drives because of all the trips between Maryland and Missouri last spring associated with our move, but the non-Interstate roads and long rural expanses going to Pensacola made it a harder drive. The only rest stops were welcome centers when we crossed state lines; we made stops at fast food places and gas stations but sometimes they were further apart than we prefer.

It was scenic…with roadcuts and forests, rivers and fields. In Arkansas there seemed to be a lot of farmers plowing…kicking up dust; I’d seen so many no-till fields in recent years that the plowing struck me as a retro strategy (and one that obviously depleted topsoil). In Mississippi, we noticed a community with blue roofs; as we got closer, we realized the blue was from tarps and there were big stacks of fallen trees nearby; a police car monitored the comings and goings from the community. By the time we got to Alabama we were tired…glad we were getting close to our destination.

Our previous visits to Florida had been primarily to the Atlantic coast and Orlando. Pensacola had a deep South vibe. The military presence (current and historical) also influenced our perception of the area. We wanted to see the Gulf Islands National Seashore and several other natural areas – for birds and plants. We stayed at a hotel with a small kitchen…took advantage of the breakfast they provided and snacked in our room in the evening after having a substantial lunch while we were out and about during the day. There was a magnolia blooming near our room.

Overall – the trip was OK but not spectacular. We learned about ourselves as much as about the area:

  • A google maps time of 11.5-12 hours is too much for us to do in a day – particularly if the route is not mostly Interstates.

  • Spring is a great time for road trips….fall will be too. Summer is often too hot and winter weather can be problematic.

  • Birding festivals give us the discipline to get up and out early…into places that are harder to find on our own in an unfamiliar area of the country. We’ll register for a festival to structure our next trip.

I’ll be posting about our Pensacola vacation in the upcoming days….stay tuned.

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.

New report deepens understanding of wind-wildlife interactions -- ScienceDaily – This article overviews the report. The 24 page report is available here. The amount of collaboration between the industry, government, conservation, academic and scientific organizations is significant and ongoing.

Marsh-Billings-Rockefeller National Historical Park Celebrates Forests – Maybe I’ll go to Vermont for this festival next September – if it’s an annual event.

These surreal jarred fish tell an urgent story of extinction – The Royal D. Suttkus Fish Collection – nearly 8 million preserved fish…a window into how 20th century development changed the Southeastern US fish….a record of that destruction.

No bones about it, this protein slows down fracture-healing -- ScienceDaily - Abundance of ApoE may explain why older people have trouble healing broken bones. Turning off ApoE completely causes fat to be deposited in arteries (a cardiovascular problem) so treatment options may involve lowering ApoE for short periods of time.

O Canada! We Like Your Food Guide – Food guides from Canada (and some other countries) … some differences from the US. Canada merges ‘dairy’ in with protein foods rather than featuring it as an independent group.

Scientists Are Getting Better at Predicting Hurricane Intensity – A new algorithm has been developed to include the complicated physical mechanisms of tropical cyclone dynamics and the way they interact with upper-ocean and atmospheric circulation. It may reduce the error of tropical cyclone prediction within a 24-hour period by 16%. Every little bit of improvement in prediction means better preparations when an intense storm is approaching.

Artworks of the Dark Zone – From caves in Tennessee and Alabama. Artwork incised in mud and inscriptions. A slideshow.

How Penn State is Cutting Greenhouse Emissions in Half – and Saving Money – Kudos to Penn State. I wonder how many other universities are doing similar things.

Empty Meditative Landscapes Visualize the Tranquil Beauty of Silence – A visual treat

Ed Hawkins “Climate Stripes” May be the Most Important Science Image so Far in This Century – Effective visualization of lots of data…becomes information. The next step is action.
