Gleanings of the Week Ending January 17, 2026

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.”

Gleanings of the Week Ending February 11, 2023

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.

Why the world feels so unstable right now – Intermittent instability of nonlinear systems of nature and global society –weather and climate, the economy, a pandemic, a war. We attempt to model nonlinear systems to predict these intermittent instabilities…but it is hard. Right now there seem to be significant nonlinear systems interacting: weather/climate + diseases (COVID-19 and bird flu (US)) + inflation + Russia’s invasion of Ukraine.

Completing The Electrical Circuit at Kilauea in Hawai'i Volcanoes National Park – The technique to get a detailed ‘CAT scan’ of the volcano…..mapping locations of subsurface magma in 3D.

Ex-cell-ent Clouds off Chile’s Coast – Open and closed-cell marine stratocumulus clouds photographed by Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra and Aqua satellites. Learning more about these clouds….contributing to better weather prediction and improving the accuracy of climate models.

The Surprising Substances Ancient Egyptians Used to Mummify the Dead – Evidently some of the substances the embalmers were using came from Southeast Asia. Perhaps embalming instigated early global trade.

Algae robots transport antibiotics to infected tissues (infographic) – Researchers inserted the modified algae into mouse windpipes…they spread into the lung tissue and killed pathogenic bacteria!

Hundreds of Frank Lloyd Wright’s Designs were never built. Here’s what they might have looked like. – Computer generated models from David Romero.

5 expert tips to protect yourself from online misinformation – We all need tools to help us distinguish information from misinformation.

Montessori: The world’s most influential school? – I sought out a Montessori pre-K and K for my daughter about 30 years ago…and it fit her needs. I have no way of analyzing how closely the school adhered to classical Montessori ideals.

An action plan to prevent Alzheimer’s disease – Defining what 2nd generation memory clinics should include.

Gallup: Fewer than half of Americans believe US healthcare is good enough – Not surprising really – it’s expensive and we are all getting more skeptical that the system is as effective as it should be for what it costs. Evidently the people in my age group (over 55) were generally more satisfied with their health care than other age groups; people old enough to qualify for Medicare may not be as anxious about costs but I was surprised that I am in the minority in thinking US healthcare is ‘subpar’ rather than ‘excellent’ or ‘good’ based on the effectiveness issue and the structure of the system overall.

30 years ago – February 1992

30 years ago – in February 1992 – it was a big month for milestones.

My paternal grandmother celebrated her 80th birthday. My mother had arranged a week-long celebration with various relatives appearing throughout the week, my daughter and I were there for the duration. My daughter had done enough airplane travel in her 2.5 years that getting from Maryland to Texas was uneventful, but the week was full of new experiences and lots of desserts; she and her cousin of similar age (the two great-grandchildren) were a pleasant distraction even when they were overly excited!  We stayed with one of my sisters for several nights because my parent’s house was needed for other relatives on those nights and my daughter discovered the fun of bunk beds (when we got home, she told her dad that she wanted bunk beds in her room). One of the enduring gifts from that birthday was a pink rose bush that a nephew and his wife brought; it is blooming profusely (in season…picture from last fall) beside my parent’s garage always reminding us of my grandmother and the couple that purchased it.

Another milestone was my daughter being accepted into the Montessori School I had selected as my first choice for her in the fall. It turned out to be a very positive experience for her over the next 3 years of pre-school and kindergarten…and was the last educational decision I made for her without her input!

Our grand piano was delivered in February 1992. It has been the largest part of our living room furniture since then! I took some pictures of it recently. Only the nicks in the legs from the vacuum cleaner give an indication of its age. It’s had an annual visit from the same piano tuner for almost the entire time!

Overlaid on those milestones – my daughter had a terrible cold and ear infection after we returned from Texas! Between our daughter and 2 careers there were frequent unexpected events; it was often a challenge to not feel overwhelmed – but there were always times to savor along the way too.

Ten Little Celebrations – August 2019

August 2019 was busy – but not as overwhelming as July. I savored the recovery time before the busy fall field trip season volunteering and my own travels. It was still easy to find little celebrations this month.

For three weeks of the month, I celebrated two mornings with Howard County Conservancy summer campers. What great experiences for me and (I hope) for the campers. Fossils, water and flight….interesting themes of high interest to the 5-12 years old groups. I could have counted 6 little celebrations but opted to count each week as 1 larger celebration since I had so many other things to celebrate.

Celebrating Coursera course Bugs 101: Insect-Human Interactions from University of Alberta (which I hope to finish by the end of the month). It was wonderful to have time to dig into an online course again.

Montessori teachers in the Wings of Fancy exhibit. A group of Montessori teachers in training came through the exhibit one morning (when it wasn’t too hot) and I celebrated conversations and that the method is still popular. My daughter certainly thrived in that type of pre-school.

Finding lots of botanical print books. Just when I think I am about to run out of online botanical books, I find a lot more…..and celebrate.

Getting a new laptop ordered. My old laptop is almost out of warranty and, even though it has a new battery and seems to be working well, I ordered a new one. I’m very excited about getting it all set up by the end of the month.

Flavorful cantaloupe. The CSA had very sweet cantaloupes this year. I celebrated melons that were as good as my memories of childhood cantaloupe from my grandparents’ farm.

Office rearrangement. I celebrated a new arrangement of my office furniture and general tidiness of my home office…in preparation for a new laptop.

Photographing a living cicada. Usually the cicada’s I photograph are not living – or are too cold to move. I celebrated seeing one fly into a tree and photographing it…while it was singing.
