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.

12/28/2025 SciTechDaily Microplastics Burrow into Blood Vessels and Fuel Heart Disease - New research led by biomedical scientists at the University of California, Riverside suggests that routine contact with microplastics — tiny particles released from packaging, clothing, and many plastic products — may speed up atherosclerosis, a condition in which arteries become clogged and can lead to heart attacks and strokes. The team studied LDLR-deficient mice, which are genetically prone to developing atherosclerosis. Both male and female mice were fed a low-fat, low-cholesterol diet comparable to what a lean and healthy person might consume. Over a nine-week period, the mice received daily doses of microplastics (10 milligrams per kilogram of body weight). These exposure levels were chosen to reflect amounts considered environmentally relevant and similar to what humans could encounter through contaminated food and water.

1/1/2026 ScienceDaily This 100-year-old teaching method is beating modern preschools - Public Montessori preschool students enter kindergarten with stronger reading, memory, and executive function skills than their peers. These gains don’t fade — they grow over time, bucking a long-standing trend in early education research. Even better, Montessori programs cost about $13,000 less per child than traditional preschool. (My daughter went to a private Montessori school for preschool-kindergarten…she enjoyed it and did very well in her subsequent education/career so I am not surprised by the results of this national trial.)

12/31/2025 Archaeology Magazine Bones of Chaco Canyon’s Imported Parrots Reexamined – A reexamination of more than 2,400 parrot bones unearthed at Chaco Canyon suggests that most of the macaws and parrots that were kept by ancient Puebloans were likely restricted to the large, multistory buildings known as great houses, where they lived in heated rooms with plastered walls.

12/31/2025 ScienceDaily Microplastics are leaking invisible chemical clouds into water - Microplastics in rivers, lakes, and oceans aren’t just drifting debris—they’re constantly leaking invisible clouds of chemicals into the water. New research shows that sunlight drives this process, causing different plastics to release distinct and evolving mixtures of dissolved organic compounds as they weather. These chemical plumes are surprisingly complex, often richer and more biologically active than natural organic matter, and include additives, broken polymer fragments, and oxidized molecules. Understanding how these chemicals evolve across different stages of plastic breakdown will be essential for assessing their long-term environmental impact.

1/2/2026 National Parks Traveler A Day in the Park: Assateague Island National Seashore – This was a great get away from where we lived in Maryland until recently. We’d cross the Bay Bridge, visit Blackwater National Wildlife Refuge and then be at Chincoteague and Assateague Island National Seashore after that.

1/2/2026 The New York Times A Study Is Retracted, Renewing Concerns About the Weedkiller Roundup - In 2000, a landmark study claimed to set the record straight on glyphosate, a contentious weedkiller used on hundreds of millions of acres of farmland. The paper found that the chemical, the active ingredient in Roundup, wasn’t a human health risk despite evidence of a cancer link. Last month, the study was retracted by the scientific journal that published it a quarter century ago, setting off a crisis of confidence in the science behind a weedkiller that has become the backbone of American food production.

1/2/2026 Smithsonian Magazine When the Bayeaux Tapestry Makes its Historic Return to England - Created in the 11th century, the delicate, 230-foot-long embroidered textile has been in France since 1077.

12/30/2025 YaleEnvironment360 2025 Was Another Exceptionally Hot Year - 2025 was the second hottest on record, surpassed only by 2024. It continues a recent trend of exceptional, unexplained warming. The last three years have been, by a wide margin, the hottest ever recorded. The recent jump in warming, which exceeded the predictions of climate models.

12/21/2025 My Modern Met Photographer Explores the Rich Complexity of Africa’s Great Rift – Photography of a place --- and an interview with the photographer.

12/17/2025 Washington Post These kitchen items may be contaminating your food with chemicals - Plastic ushered in a new era of convenience and filled homes with cheap, disposable goods. But it also has exposed ordinary people to tens of thousands of chemicals that slip out of those items into household dust, food, water — and from there, into bodies. Some of these chemicals are known to disrupt pregnancies, triggering birth defects and fertility problems later in life; others have been linked to cancer and developmental problems. “The problem is, none of the plastics that we have right now are safe,” said Wagner, of Norwegian University of Science and Technology. “That’s not a very nice thing to hear, but that’s what the data tell us.”

Happy New Year 2026

A new year – and the annual thoughts about beginnings – where do I go from here. I am trying to sustain my lifelong optimism, but it is hard with the continuing world turmoil particularly at the Federal level in the US. It is frustrating that our response to the biggest challenges of our time (climate change, plastic pollution) seems to be lost in the chaos, perhaps more in the US that elsewhere in the world.

Sunrise is also a symbolic beginning of more than just the day. This time of year, it is very easy to be up in time to see it…and take a few moments to savor the beauty of it and the natural world….making an effort to imagine a positive path of the future of human endeavors and our home planet.  

Gleanings of the Week Ending November 8, 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.

Childhood Exposure to Plastic Raises Lifetime Health Risks - Scientists analyzed decades of research into the impact on pregnant mothers, fetuses, and children of three chemical additives — phthalates, bisphenols, and perfluoroalkyl substances — that make plastic more flexible, more rigid, or more resistant to heat or water. Early exposure to these chemicals can leave children at greater risk of heart disease, obesity, infertility, and asthma well into adolescence and adulthood. Plastic additives are also believed to affect the development of the brain, with studies linking the chemicals to lower IQ, ADHD, and autism. The widespread use of plastic is exacting a deepening toll, with Americans paying an estimated $250 billion yearly to treat ailments linked to plastic.

Scientists Resurrect 40,000-Year-Old Microbes from Alaskan Permafrost. What They Found Raised Worries About the Future of a Warming Arctic - Roughly 40,000 years ago, microbes went dormant in a rock-like layer of frozen soil near the future site of Fairbanks, Alaska. Now, researchers have successfully “reawakened” the tiny creatures, raising concerns about how those microbes could increase greenhouse gas emissions in a warming Arctic.

The Butterflies of Marinduque: Small Wings, Big Changes - Marinduque supplies about 85% of the Philippine’s butterfly pupae exports. Beyond trade, butterflies have become symbols of livelihood, culture, and conservation for the island.

A simple fatty acid could restore failing vision - Retinal polyunsaturated fatty acid supplementation reverses aging-related vision decline in mice….and systemic lipid supplementation could potentially counteract the effects of age on the immune system. But will in work in humans…that’s still TBD.

Is it possible to lose weight on an 'Ozempic' diet? – Study findings suggest that there's some kind of mechanism we can tap into to restore healthy eating without drugs by limiting the sense of reward and achieving a sense of satisfaction without overeating.

This Chilling Recording Reveals Large Bats Catching, Killing and Eating Birds Midflight – How the greater noctule bat, the largest bat species in Europe, catches and eats its prey.

Fentanyl overdoses among seniors surge 9,000% — A hidden crisis few saw coming - Fatal overdoses among adults 65 and older involving fentanyl mixed with stimulants such as cocaine and methamphetamines have risen dramatically, climbing 9,000% in the past eight years. The rate now mirrors that seen in younger adults. The rise in fentanyl deaths involving stimulants in older adults began to sharply rise in 2020, while deaths linked to other substances stayed the same or declined. Cocaine and methamphetamines were the most common stimulants paired with fentanyl among the older adults studied, surpassing alcohol, heroin, and benzodiazepines such as Xanax and Valium.

Billions of bacteria lurk in your shower, just waiting to spray you in the face - should you be worried? - For most people the risk of catching a bug from your shower head is low, particularly if you are using it frequently. Running the shower for 60-90 seconds, allowing it warm up before stepping under the spray, also means it is also doing some useful work in that time, flushing out many of the microbes. This is particularly advisable after a holiday or any long gap between using the shower. Regular cleaning by running very hot water through the shower, along with descaling your shower head or soaking it in lemon juice can help to disrupt the microbes living there and control the size of biofilms.

Dolphins may be getting Alzheimer’s from toxic ocean blooms - Dolphins washing up on Florida’s shores may be victims of the same kind of brain degeneration seen in humans with Alzheimer’s disease. Researchers discovered that cyanobacterial toxins—worsened by climate change and nutrient pollution—accumulate in marine food chains, damaging dolphin brains with misfolded proteins and Alzheimer’s-like pathology. Since dolphins are considered environmental sentinels for toxic exposures in marine environments there are concerns about human health issues associated with cyanobacterial blooms. In 2024, Miami Dade County had the highest prevalence of Alzheimer's disease in the United States.

Nigeria, a Major Oil Producer, Sees Beginnings of a Solar Boom - For Nigerians, the cost savings from ditching diesel mean that a solar panel pays for itself within six months. Homeowners who can afford the up-front costs are installing rooftop solar in large numbers, while some villages are setting up community solar and battery projects. Solar is making huge gains in Nigeria, with imports of Chinese solar panels growing by two-thirds between June 2024 and June 2025. n Pakistan, high fuel prices, a byproduct of the Ukraine war and the loss of a fuel subsidy, have spurred the mass adoption of solar.

Plastics Crisis: Recycle Inventory

I have been recycling for a long time…starting out when newspapers and cans (separately) were the only items that could be recycled. By the time we moved from Maryland, the county where we lived supplied recycle bins for everyone; the cost was included with trash service. The items we recycled included cardboard, paper, glass jars/bottles, tin cans, aluminum cans, plastic bottles/jugs, and milk cartons/juice boxes. We always had more in the recycle bin than in the trash bin and that seemed true for everyone in our neighborhood.

When we moved to Missouri, the curbside recycling was an added cost beyond trash pickup and we quickly discovered that not as many people recycled. The list of recyclables did not include glass or milk cartons/juice boxes. The local recycling center accepts glass, so we periodically take glass there. The milk cartons/juice boxes go into the trash. We still have more in our recycling bin than in trash. The bulk is cardboard/paper, but the next is plastic…followed by tin/aluminum cans.

Focusing in on the plastic that is in our recycling bin….

  • There are soft drink bottles…but those will be going away shortly because I will either stop drinking soft drinks or buy them in aluminum cans.

  • There are milk jugs. I buy milk in jugs rather that cartons because the jugs can be recycled. There are not plastic free options for milk since even the cartons have plastic coating them.

  • There are a few cleaned-out bottles with caps. It is not as clear that these plastics are always recycled; for that reason, I am actively trying to reduce/eliminate them. I have already eliminated laundry detergent (buying laundry sheets in paper packaging instead). I sometimes don’t recycle bottles that held products that are hard to clean out (peanut butter, for example) and plan to buy those things in glass from now on which is more reliably recycled. I also am experimenting with DIY toilet bowl cleaner (soda, vinegar, essential oil) rather than buying the bottled version.

  • Plastic bags are collected and taken back to stores that accept them for recycling; I am skeptical that they are recycled but it is challenging to find out what really happens to them. They are usually not plastic shopping bags these days since we use reusable bags so frequently. They are bread bags, plastic from around soft drinks (although we are getting better at avoiding that), plastic bags that held food (popcorn, produce), packaging from clothing purchases, air ‘pillows’ from packaging, toilet paper packaging). I am overtly trying to reduce or eliminate this type of material even though it is supposedly recycled.

Even with all the effort I put into recycling of plastic – a lot ends up in the trash because it is not recyclable and even some of the plastic that enters the recycling process ends up in landfills because it is cheaper to make new plastic rather than to process recycled plastic!

We cannot recycle our way out of the plastic crisis! Read The May 2022 report The Real Truth About the U.S. Plastics Recycling Rate from Beyond Plastics. It documents a recycling rate of just 5-6% for post-consumer plastic waste in the U.S. for 2021. The report also reveals that while plastics recycling is on the decline, the per capita generation of plastic waste has increased by 263% since 1980. The failure of plastic recycling is in contrast to paper which is recycled at 66% (2020 figure per American Forest and Products Association). High recycling rates of post-consumer paper, cardboard, and metals proves that recycling works to reclaim valuable natural material resources. It is plastic recycling that has always failed as it has never reached 10% even when millions of tons of plastic waste per year were counted as recycled when exported to China.
