Gleanings of the Week Ending February 28, 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.

2/16/2026 Journal of Advanced Research Association between exposure to microplastics and lipid disorders: A case-control study – Study with 239 patients aged ≥18 years who underwent fiberoptic bronchoscopy with bronchoalveolar lavage fluid (BALF) collected. Microplastics in BALF were identified and quantified using laser direct infrared spectroscopy. Fourteen main types of microplastics were detected in BALF with PE being dominant. Exposure to microplastics was associated with elevated levels of total cholesterol.

2/16/2026 National Parks Traveler A Day in the Park: Canyon de Chelly National Monument – This article reminded me of a visit to the park in 1983! We hiked the White House Trail, and I remember wading across a stream with the 4 of us holding hands just in case there was a pocket of quicksand. We managed to get through with neither of the two cameras getting dipped in the water.

2/13/2026 Science Daily Scientists make microplastics glow to see what they do inside your body - A new study proposes an innovative fluorescence-based strategy that could allow researchers to track microplastics in real time as they move, transform, and degrade inside biological systems.

2/15/2026 Our World in Data Four minutes of air conditioning - In at least 45 countries, the average residential electricity use per person for an entire day is less than the electricity that is required to power an air conditioner for one hour. In India, the daily electricity budget is sufficient for only 44 minutes of AC. In Nigeria, just 13 minutes; and in South Sudan, just 4. Most people in some of the world’s hottest countries do not use AC. The most recent data from the International Energy Agency suggests that just 5% of households in India, 6% in South Africa, and 16% in Brazil had air conditioning. In the very poorest countries, almost no one has it. In colder countries, we wouldn’t accept people freezing in their homes. The opposite is also true: we shouldn’t accept people working and living in oppressive heat without ways to cool themselves down.

2/15/2026 Planetization South Carolina Mapping Tool Tracks Marsh Migration From Sea Level Rise - A new mapping tool funded by the National Fish and Wildlife Foundation maps South Carolina’s shifting salt marshes, which are pushing inland as seawater levels rise. The mapping tool translates theoretical projections into actionable data. For a more detailed explanation and videos see the article on Governing.

1/23/2026 The Scientist Antibiotic Resistance Is Rising: 4 Trends Could Change That Course - Antibiotic resistance is sometimes framed as an inevitable catastrophe. But I believe the reality is more hopeful: Society is entering an era of smarter diagnostics, innovative therapies, ecosystem-level strategies and policy reforms aimed at rebuilding the antibiotic pipeline in addition to addressing stewardship. For the public, this means better tools and stronger systems of protection. For researchers and policymakers, it means collaborating in new ways. The question now isn’t whether there are solutions to antibiotic resistance – it’s whether society will act fast enough to use them.

2/11/2026 Smithsonian Magazine Ice Fishermen Catch Record-Breaking 244-Pound Atlantic Halibut After Hours-Long Struggle - The fish measured more than six and a half feet long and easily broke the previous record—194 pounds—for the largest halibut caught on the Saguenay, which had been set last winter. The record-breaking Saguenay fish was the 27th halibut hooked this winter as part of the research project. After organs are removed for study, the fishermen will get to keep and split roughly 170 pounds of meat.

2/16/2026 Science Daily Microplastics have reached Antarctica’s only native insect - Scientists have discovered that Belgica antarctica — a tiny, rice-sized midge and the southernmost insect on Earth — is already ingesting microplastics in the wild. While lab tests showed the hardy larvae can survive short-term exposure without obvious harm, those exposed to higher plastic levels had reduced fat reserves, hinting at hidden energy costs.

2/16/2023 Cool Green Science 8 of the World’s Little-Known Wildlife Migrations – Lots of different kinds of animals of this list!

2/16/2026 Yale Environment 360 Despite Rollbacks, U.S. Fossil Fuels Face Tough Road Ahead - The weakening of environmental regulations belies the downward trajectory for fossil fuels under President Trump. Today, the U.S. coal fleet is the smallest it has been in decades, having shrunk roughly in half since 2010. There are no new coal plants under construction. Oil is expected to stagnate as global production outpaces demand. Oil executives say the shale boom may be coming to an end. Natural gas remains a bright spot for U.S. fossil fuels as a recent boom in gas exports continues to drive demand for U.S. gas

A Five-Pound Hunk of the World’s Oldest Known Synthesized Pigment Was Found in Nero’s Palace – Egyptian Blue. The pigment is a synthetic pigment produced by firing a mixture of silica, limestone and minerals containing copper and sodium carbonate at high temperatures. The Roman architect Vitruvius recorded the recipe in his treatise De Architectura in the first century B.C.E., reflecting how the color spread through the Mediterranean world. Archaeologists discover traces of Egyptian blue that are all but imperceptible to the human eye. For instance, with the help of microscopes and luminescent imaging, researchers at the British Museum discovered that Egyptian blue once adorned the Parthenon marbles.

See the First Stunning Images Taken by the Blue Ghost Lunar Lander on Its ‘Scenic Route’ to the Moon – It still has a few months before reaching the moon….lots of Blue Marble views.

Changing cholesterol over time tied to risk of dementia – Interesting result. I wondered if cholesterol fluctuation is more concerning that merely being high….that there in an underlying reason for the fluctuations that indicates a problem that is not being directly addressed by the medications that generally are trying to lower cholesterol.

Astronomers have spied an asteroid that may be heading for Earth. Here’s what we know so far – On December 22, 2032,  the asteroid 2024 Y04 might collide with Earth. It was first detected on December 27, 2024 and will continue to be observed until it will be lost to our telescopes until we will see it again in 2028 and refine what we know….be able know for sure whether there will be a collision and where on earth the collision will be. In just the past few years, we have discovered 11 asteroids before they hit our planet. In each case, we have predicted where they would hit, and watched the results. We have also, in recent years, demonstrated a growing capacity to deflect potentially threatening asteroids.

An Arctic 'beyond recognition' by 2100 - Under 2.7 degrees Celsius of warming, the Arctic region is likely to experience the following effects:

• Virtually every day of the year will have air temperatures exceeding pre-industrial temperature extremes.

• The Arctic Ocean will be free of sea ice for several months each summer.

• The area of the Greenland Ice Sheet that experiences more than a month of surface temperatures above 0 degrees Celsius will quadruple compared with pre-industrial conditions, causing global sea levels to rise faster.

• Surface-level permafrost will decrease by 50 percent of pre-industrial levels.

Study Highlights Challenges to The Electrification Of Homes In The US - Solar powered homes demonstrated impressive resilience during summer heat waves. However, they proved remarkably vulnerable during winter storms. In fact, fully electrified homes were nearly three times more vulnerable to winter outages, compared to those drawing power from mixed energy sources. The integration of distributed energy resources such as solar and battery storage has emerged as a critical factor in household resilience.

Sky skimmers: The race to fly satellites at the lowest orbits yet – A handful of pioneering companies have begun work on designs for satellites that may be able to orbit the planet at unusually low altitudes while simultaneously harvesting air and using it to make propellant – literally on the fly. This new generation of orbiters could enable ultra-high-definition surveillance of activities on the ground, or superfast satellite-based communications. The race is on. (I wondered if the US activities mentioned in the post are going to survive budget cuts.)

Low-level traffic air pollution linked to liver damage and fatty liver disease - When we inhale air pollution, the very tiny particles known as PM2.5 enter the bloodstream through the lungs. The liver, which filters toxins from the blood, then accumulates these substances, which can include heavy metals such as arsenic, lead, nickel and zinc. The study authors suggest avoiding peak hour traffic, taking less congested routes when walking or cycling or consider wearing a mask, and keeping car windows closed with air recirculation mode on while driving in heavy traffic.

Hitting Its Stride or Hitting a Wall? South Texas at a Watershed Moment - Between extreme heat, flooding, drought, and the vagaries of politics and international trade, there is a growing fear that the Valley’s boom times could come to a grinding halt — or worse, that the region will experience the same type of climate-related exodus that has pushed many of today’s current immigrants to its doorstep. An even bigger question is whether the region has become a harbinger of mounting international tensions over shrinking resources that are expected to play out with more frequency in coming years.

Searching the entire sky for the secrets to our universe - As soon as the end of February, NASA and the Jet Propulsion Laboratory will launch a new telescope into orbit around the Earth. SPHEREx will join the ranks of other space telescopes, filling in a crucial gap by detecting infrared light with wavelengths too long to see with the naked eye. It's an important addition because no single instrument can fully perceive the universe and its contents. Infrared can also be used to detect the unique fingerprints of particular molecules in the universe, including the basic components of life — water and organic materials frozen in the ices of interstellar dust clouds where stars are born.

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.

Digesta: An overlooked source of Ice Age carbs – Partially digested vegetable matter from large herbivores (such as bison) might have provided carbohydrates and other macro nutrients reducing the burden of ‘gathering’ for a time after an animal was slaughtered. Perhaps during migration, it was the dominant source of carbohydrates in a situation with reduced accessibility of plants. And maybe women participated in hunting to a larger extent than previously thought; ‘grave goods’ in burials found that perhaps 30-50% of all large-game hunters in the Americans during the late glacial era may have been female!

Anemia found to be common in ancient mummified Egyptian children – CT scans were done on 21 child mummies (between ages 1-14 at death) to study the skeleton inside the wrapped remains. 7 of the children had pathological enlargement of the cranial vault, typically associated with anemia. The study also found a child that died less than a year after birth of thalassemia (the body could not produce hemoglobin).

Bathing through the ages: 1300 – 1848 – 14th and 15th century bathhouses provided services beyond bathing (lancing abscesses, pulling teeth, steam rooms, mineral baths, cupping, herbal concoctions); they helped shape the public health services of larger cities as they grew, and health conditions deteriorated. By the 16th century, bathhouses started to disappear as Europe was ravished by plague, smallpox, and syphilis. But – by the 1800s, sanitation reformers were arguing that making bathing facilities available to the poorest classes of society offered an ‘affordable and immediate way’ of improving public cleanliness and health. Bathhouses, along with waterworks and sewage systems, laid the foundation for the UK Health Act of 1848.

Glass or Plastic: which is better for the environment? – There is not a clear-cut answer. I will lean toward glass because of its non-toxicity….but I also realize we need to improve the ways we use it (less single use) and recycle it (better sorting and improved processing that avoids melting it twice),

Greener batteries – Batteries with Organic Electrode Materials (OEMs) are one alternative that is being researched…in this case using azobenzene by a research team at a Chinese University. Hopefully there are researchers around the world also focused on producing greener batteries.

Protein powders: When should you use them? – I think of protein powder as an ultra-processed food….a food I only want to use if I can’t manage to get enough protein from unprocessed or lightly processed foods in my diet. It is not something I want to use every day!

Long Reviled as ‘Ugly,’ Sea Lampreys Finally Get Some Respect – Not so long ago…lampreys were an organism that seemed destined for extinction because we only saw it as a predator that wiped out the Great Lakes lake-trout fishery. Now, the consensus is that, in their natural habitat, marine lampreys are “keystone species” supporting vast aquatic and terrestrial ecosystems. They provide food for insects, crayfish, fish, turtles, minks, otters, vultures, herons, loons, ospreys, eagles, and hundreds of other predators and scavengers. Lamprey larvae, embedded in the stream bed, maintain water quality by filter feeding; and they attract spawning adults from the sea by releasing pheromones. Because adults die after spawning, they infuse sterile headwaters with nutrients from the sea. When marine lampreys build their communal nests, they clear silt from the river bottom, providing spawning habitat for countless native fish, especially trout and salmon. Wow!

The Pacific Garbage Patch Is Home to Coastal Species—in the Middle of the Ocean – A surprise for researchers…they found shrimp-like arthropods, sea anemones and mollusks, Pacific oysters, orange-striped anemones and ragworms. Crustaceans were taking care of eggs and anemones were cloning themselves. This does not make the Garbage Patch acceptable!

Photography In the National Parks: Same Spot, Different Time / Season / Weather – Spots in Yellowstone, Mount Rainier, and Olympic National Parks.

Greater fat stores and cholesterol increase with brain volume, but beyond a certain point they are associated with faster brain aging – People in wealthy countries have largely grown accustomed to eating more and exercising less -- habits that are associated with decreased brain volumes and faster cognitive decline. This study looks at indigenous people (two tribes in Bolivia that live along tributaries of the Amazon). The tribe that was closer to our subsistence ancestors had the lowest rates of hear disease and minimal dementia; in this group - BMI, adiposity and higher levels of "bad" cholesterol were associated with bigger brain volumes in older adults!
