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

Ten Little Celebrations – February 2026

I celebrated getting outdoors in February and a flurry of education related activities!

Melting snow. We had snow on the ground for the last week of January and into February. We all celebrated when it finally melted although it was pretty as long as one didn’t have to get out and about.

Cranberry orange relish. I used my last frozen cranberries to make cranberry orange relish – savored the flavor….and will miss it until the cranberries are in the stores again in the fall.

Ozark Witch Hazel blooming. My small Ozark Witch Hazel I planted last spring is blooming. It retained its leaves so the blooms were a little difficult to see.

Missouri fish and amphibian webinars. There were two webinars that were a pleasant surprise in February – they were very well done.

Salmon salad. I celebrated the flavors of salmon, pear, and cabbage with a lemon honey olive oil dressing – with a feisty lime blend of seasonings.

Training for master naturalists. I celebrated that the training plan for the new cohort of Missouri Master Naturalists in our area seems to be coming together. It looked daunting at first.

Macro and high key flower photography. I celebrated a winter photography project – a purchased bouquet on the windowsill in my office.

Ecoregion maps of Missouri. Looking at maps from an out-of-print Atlas was interesting and I celebrated how great they will fit into a presentation for the master naturalist training next fall – the module I will be presenting.

Wilson’s Creek National Battlefield. I celebrated the longest hike of the month – interesting place for birds and habitats…and also thinking about history and the way it looked during the Civil War.

Plastics and human health webinar.  I heard a webinar on the same topic with the same speaker from a year ago – and realized that this topic is progressing rapidly. I celebrated that she’ll likely continue to present webinars and include new information.

2/2/2026 York Daily Record Mountains of plastic turf in limbo after Pa. recycling project falters - A Danish company's plan to build an artificial turf recycling plant in Pennsylvania has failed due to bankruptcy. The state is now responsible for cleaning up thousands of tons of abandoned turf stockpiled across three counties. The abandoned turf, which may contain "forever chemicals," will now be sent to a landfill instead of being recycled.

2/8/2026 Clean Technica Why China’s Aluminum Industry May Have Reached Peak CO2 - Relocation to hydro regions is largely complete. Secondary aluminum is rising into double digit millions of tons. Coal heavy output has already peaked and begun to edge down. Renewable penetration in coal regions continues to rise. Reversing this trend would require renewed growth in coal-based smelting or a collapse in recycling, neither of which fits China’s industrial or energy trajectory.

2/9/2026 BBC Fungi mining and giant waste piles: How to get rare earths without mining rock -Gigantic heaps of coal ash, mine tailings and red mud are traditionally expensive and difficult to deal with. But if new processes allow rare earth harvesters to engage in remediation while hoovering up rare earths, then industry and environmentalists might no longer be at odds over what to do about all that waste.

2/8/2026 Science Daily Scientists finally solve a 100-year-old mystery in the air we breathe - The new model offers a stronger foundation for understanding how airborne irregularly shaped nanoparticles (like soot, microplastics, viruses) move across a wide range of scientific fields. These include air quality monitoring, climate modeling, nanotechnology, and medicine. The approach could improve predictions of how pollution spreads through cities, how wildfire smoke or volcanic ash travels through the atmosphere, and how engineered nanoparticles behave in industrial and medical applications.

2/6/2026 Archaeology Magazine Aqueduct at Early Italian Villa Explored - Based on the construction method of this hydraulic system, it might have been originally created to serve a rural village predating the construction of the villa, during a period before the Romans had fully solidified their control over this region of Italy.

2/4/2026 Yale Environment 360 Seas to Rise Around the World — but Not in Greenland - The reasons are twofold. 1)  the massive Greenland ice sheet, which at its center is roughly a mile thick, compresses the land underneath. As the ice melts, the land rebounds, rising above the sea. 2) the Greenland ice sheet is so large that it exerts a gravitational pull on surrounding waters, drawing them higher. But in a warming Arctic, Greenland is shedding some 200 billion tons of ice a year. As its gravitational pull wanes, waters recede.

2/5/2026 Smithsonian Magazine Air Pollution Can Cause Some Ants to Turn on One Another—and Neglect Their Young - As insect populations decline around the world, the findings further point to air pollutants as a possible cause, in addition to pesticides, light pollution and other factors. The work is especially important given the crucial role ants play in maintaining healthy habitats, such as dispersing seeds, controlling pests and aerating soil.

2/4/2025 Cool Green Science Reading the Tree Rings – Great photographs by Greg Kahn for this article. One of the labs visited for the article was the Laboratory of Tree-Ring Research at the University of Arizona that I visited when my daughter was a graduate student in Tucson in 2015 (my blog post about it here).

2/4/2026 Compound Interest World Cancer Day: How antibody–drug conjugates for cancer work - Our ability to use medicines to target more effectively is improving, and antibody–drug conjugates are an increasingly effective tool in combating cancers. This graphic explains what they are, how they work, and how they might improve in the future.

2/4/2026 National Parks Traveler Florida’s Ailing Reef - The reef is fighting for its very survival, beset by the trauma of climate change and warming water, commercial and recreational fishing, and drainage pollution coming from Florida’s canal system.

2026 Million Marker Test Kit – I’m going to do as much as I can to reduce microplastics…then do this test….probably next summer. It is advertised as the only mail-in test for BPA, BPS, BPF, phthalates, parabens, and oxybenzone.

2/3/2026 Yale 360 China to See Solar Capacity Outstrip Coal Capacity This Year - By the end of 2026, wind and solar will account for nearly half of China’s power capacity. Including hydro and nuclear power, clean energy will amount to nearly two-thirds of total power capacity, while coal will amount to a third. Competing with cheap solar and wind, a large share of coal plants are now operating at a loss.

2/1/2026 Cool Green Science Catching Sharks for Science - On Long Beach Island, volunteer anglers help researchers uncover the hidden journeys of sharks in threatened salt marsh ecosystems.

2/3/2026 Science Daily Even remote Pacific fish are full of microplastics - Even in some of the most isolated corners of the Pacific, plastic pollution has quietly worked its way into the food web. A large analysis of fish caught around Fiji, Tonga, Tuvalu, and Vanuatu found that roughly one in three contained microplastics, with Fiji standing out for especially high contamination. Reef and bottom-dwelling fish were most affected, linking exposure to where fish live and how they feed.

2/1/2026 National Parks Traveler New York Art Teacher Earns 30 National Park Resident Artist Spots In 10 Years – Artist-in-residence at National Park Service sites. Many of the programs are funded by nonprofits, grants, or donations made directly to the Park Service.

1/29/2026 BBC From bad omen to national treasure: The rare bone-swallower stork saved by a female army - Known locally as the hargila (or "bone-swallower") for its scavenging ways, greater adjutant storks are unique birds. Roughly 5ft (1.5m) tall, they aren't only imposing but also play a vital role in maintaining the health of a wetland ecosystem. As scavengers that consume and clean up carcasses, they prevent the spread of disease and break down decaying organic matter, recycling essential nutrients back into the soil. They were feared, reviled and in some communities, hunted for their meat which was once widely used in folk medicine as a cure for leprosy or antidote to poison.

1/28/2026 Archaeology Magazine Study tracks wild potato across the Southwest - People carried a small, wild potato known as the Four Corners potato (Solanum jamesii), across the southwestern United States some 10,000 years ago.

1/27/2026 Super Age Wellness Is Finally Admitting It Got the Last Decade Wrong – The article lists 10 trends from the 2026 Global Wellness Report. One of the 10 is “Microplastics are at threat to healthspan.”

Air quality

I’ve been noticing that the air quality where I live (as reported in The Weather Channel app) has not been good during the recent cold weather. The primary pollutant is always Micro Dust/PM2.5. Since transportation sources of pollution (cars, trucks) are, if anything, a little lower during cold and snowy weather – I am assuming that the uptick is from the electricity generating coal plant or wood burning stoves/fireplaces.

I notice that my eyes are the first to register air quality issues. They start to itch or feel gritty – not as bad as a floating eyelash but not comfortable. Saline drops help but time consuming to do frequently. I find myself just forging ahead with my eyes itching and trying not to rub them. Recently I have been wondering if some of my ‘allergies’ (runny nose and sneezing that comes and goes over the course of the day) are PM2.5 related rather than pollen since there isn’t pollen in the air in winter.

If the day is orange – like shown in the screen shot – I try to stay indoors with the filters of my HVAC and some room air purifiers between me and the ‘bad air.’ That is possible for me most of the time since I am a post-career person. I do sometimes have things I do away from home, but they are mostly indoors this time of year and presumably well filtered/ventilated. I am a little anxious about some ‘winter wellness’ hikes I have planned…hoping that the air quality will be ‘green’ when those occur.

I enjoy being outdoors and realize that air quality will impact when I will be comfortable as time goes on (i.e. air quality will deteriorate since there is less being done right not to reverse the trend). Working in my yard won’t be impacted too much since I can simply check the air quality and only go out when it is ‘green.’ I hope I can get through a few more years of volunteering in the Butterfly House at the Springfield Botanical Garden during the summer months; signing up for shifts is done well in advance and the air quality could be problematic when the day arrives…I want to be a dependable volunteer but do I go even if the air quality is poor?

The air quality in Lewisville TX (where I go monthly to visit my dad) is considerably worse than in Springfield MO. This winter it has been orange or red most of the times I’ve been in the area. It’s been too cold to take Dad for a walk outside – and I will always check the air quality before taking him for an outdoor walk even when the weather is pleasant again. There are times that Oklahoma smells smokey (grass fires or power plants?) as I drive through. I am adding a small air purifier to the inside of the car and not doing a lot outdoors when I am there unless I check and the air quality happens to be ‘green.’

I find myself wondering what contributes to the air quality being ‘not green,’ but it is hard to tease out that information. The measurement just reports how much PM2.5 there is. I hope that some organization begins to make the contributors more visible to the public (and it would be great if The Weather Channel added that info in their app). Would it spur more people to push for changes to utilities….to retire coal burning plants a quickly as possible?

12/5/2025 The Scientist The Ice is Alive: Uncovering the Vanishing World of Glacial Microbes - The ice teems with an invisible and thriving biosphere, lush with bacteria, fungi, and viruses. Scientists have estimated that the glaciers and ice sheets around the globe could contain as many as 1029 cells. The most dynamic … is the surface, where windblown dust mixes with microorganisms to form a dark, granular sediment known as cryoconite. Because this aggregate is darker than the surrounding white ice, it absorbs more solar radiation, melting the ice beneath it. This melting creates water-filled depressions called cryoconite holes that pockmark vast areas of the ice sheet. Cryoconite holes are far from simple puddles; they are oases of life in a polar desert.

1/14/2026 The Conversation Native pollinators need more support than honeybees in Australia – here’s why - Since the 1990s, the global decline of pollinators due to human activities, climate change and diseases has been a serious concern, especially in Europe and North America. The honeybee is so good at invading and proliferating in Australian landscapes, we now have some of the highest reported densities of feral honeybees in the world. Despite the global pollinator decline, honeybees haven’t disappeared anywhere in the world, even in countries with far fewer resources than Australia. Nor has any plant species gone extinct from a lack of honeybees. In contrast, there is overseas evidence of plant population declines due to the presence of honeybees and lack of native pollinators.

1/13/2026 Yale Environment 360 Photos Capture the Breathtaking Scale of China’s Wind and Solar Buildout - Last year China installed more than half of all wind and solar added globally. In May alone, it added enough renewable energy to power Poland, installing solar panels at a rate of roughly 100 every second.

1/12/2026 Compound Interest What are rubber ducks made from? - Scientists discovered polyvinyl chloride, or PVC for short, accidentally in the 1800s on more than one occasion. A hard and brittle plastic, PVC had little commercial use until it was mixed with softening plasticizers to make a much more moldable material. The modern rubber duck is not made from rubber, but from plasticized PVC colored with a bright yellow pigment.

1/13/2026 Clean Technica EPA Cooks the Books on Industrial Pollution Costs – They (EPA) will henceforth consider only the economic cost of the regulations to corporations, and if they are deemed to be too burdensome, those regulations will be softened in order to avoid undue economic harm to the polluters. This includes fine particulates (2.5 microns or less) that include microplastics and fossil fuel combustion products….contributing to many negative health outcomes.

1/13/2026 UPI U.S. greenhouse gas emissions growing faster than economy - For the first time in three years annual U.S. greenhouse gas emissions increased, climbing by 2.4% in 2025 as federal policy shifted back to fossil fuels. For the first time in three years annual U.S. greenhouse gas emissions increased, climbing by 2.4% in 2025 as federal policy shifted back to fossil fuels.

1/11/2026 Science Daily A room full of flu patients and no one got sick - n a striking real-world experiment, flu patients spent days indoors with healthy volunteers, but the virus never spread. Researchers found that limited coughing and well-mixed indoor air kept virus levels low, even with close contact. Age may have helped too, since middle-aged adults are less likely to catch the flu than younger people. The results highlight ventilation, air movement, and masks as key defenses against infection.

1/15/2026 BBC Rare images of Europe's 'ghost cat' - After several decades, this mysterious little beast is returning to our forests.

1/14/2026 NASA Earth Observatory Fires on the Rise in the Far North - In the far north, wildfires are breaking old patterns. Satellite data show that wildland fires once scattered across the Arctic are now surging in numbers—particularly in northern Eurasia—and many are burning more intensely than before. n the 2000s, fires north of 60 degrees latitude appeared across both North America and Eurasia, but starting in the early 2010s, their numbers skyrocketed, most dramatically in Eurasia. Even the icy island of Greenland entered a new fire regime during this period, experiencing more large fires, though still too few to be visible on these maps. Researchers attribute these trends to rising temperatures, which have made northern landscapes more flammable, along with a poleward expansion of lightning—the primary ignition source for these fires.

1/3/2026 The Scientist Polio Vaccine History: The Shot That Saved Millions - On April 12, 1955, when the Salk polio vaccine was declared “safe and effective,” church bells rang out, kids were let out of school, and headlines around the world celebrated the victory over polio. When asked whether he was going to patent the vaccine, Salk told journalist Edward R. Murrow it belonged to the people and would be like “patenting the sun.”

1/8/2026 Smithsonian Magazine Hundreds of Flowering Species Bloomed Across Britain and Ireland Last Winter - Citizen scientists in the British Isles documented more than 300 native plant species blooming in early 2025, a phenomenon likely caused by climate change. While it’s lovely to see so many wildflowers in bloom … it’s also a sad reflection of the way our climate is changing and the knock-on effects this might have for all the wildlife—bees and other pollinators, butterflies and all the larger creatures further up the food chain—that depend on plants. If flowering times are increasingly out of sync with insect hatching times, the consequences could be very serious.

1/8/206 People in Brazil are living past 110 and scientists want to know why – Brazil’s highly diverse population harbors millions of genetic variants missing from standard datasets, including rare changes linked to immune strength and cellular maintenance. Brazilian supercentenarians often remain mentally sharp, survive serious infections, and come from families where multiple members live past 100. Together, they reveal aging not as inevitable decline, but as a form of biological resilience.

1/7/2026 The Conversation Surprising number of foods contain microplastics. Here’s how to reduce the amount you consume - While eliminating plastics entirely from our diets may be impossible, making these swaps should help to reduce your exposure.

1/6/2026 Nature Defossilize our chemical world - Achieving net zero means eliminating fossil fuels, not carbon — the chemical element has a crucial part to play in powering the modern world. Defossilization means finding sustainable ways to make carbon-based chemicals. Alternative sources of carbon include the atmosphere and plants, as well as carbon in existing biological or industrial waste, such as used plastics or agricultural residue. In some cases, these chemicals will eventually return carbon dioxide to the atmosphere through burning or biodegradation. In principle, this will occur as part of a circular process, rather than one that has added greenhouse gases.

1/5/2026 Planetizen The Child Population in These Cities is Dropping Fast - The proportion of young children in western U.S. metros is falling faster than in other parts of the country. Lower birth rates can sometimes ease immediate pressure on housing and schools but also lead to challenges in supporting economic growth and elder care, as the ratio of working adults to retirees declines.

1/4/2026 Washington Post What we learned about microplastics in 2025 - For many scientists, 2025 was the year of microplastics. It’s only in the past year or so that we have begun to understand that the tiny plastics — including some that are impossible to see with the naked eye — are in our bodies and food as well.

1/9/2026 Science Alert Study Finds Microplastics Are Widespread in Popular Seafoods - In the Pacific Northwest – a region of North America renowned for its seafood – researchers have found particles from our waste and pollution swimming in the edible tissue of just about every fish and shellfish they collected.

12/18/2025 Yale Environment 360 After Ruining a Treasured Water Resource, Iran Is Drying Up - Iran is looking to relocate the nation’s capital because of severe water shortages that make Tehran unsustainable. Experts say the crisis was caused by years of ill-conceived dam projects and overpumping that destroyed a centuries-old system for tapping underground reserves. 

1/8/2026 BBC The animals saved in Greece's ancient accidental 'arks' - Shielded from development and agriculture, many archaeological sites have now become inadvertent safe harbors for plants and animals. In Italy, rare orchids flower around an Etruscan necropolis. In the ancient Greek religious centre of Delphi, researchers found what they believe is a new species of snail – just 2mm (0.08in) long – suspected to live only in that area. In recent years, two new species of lizard were identified in Machu Picchu that may have once had a wider range and today enjoy the relatively undisturbed conditions of the ancient sanctuary. To better understand the connection between historical sites and nature, in 2022 the Greek government launched the Biodiversity in Archaeological Sites research project. Over two years, 49 specialists in all kinds of plants and animals surveyed 20 archaeological sites that spanned Greek history.

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.

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.”

Plastics Crisis – Healthy Food in Unhealthy Packaging

Plastic dominates packing in the grocery stores – even in the produce section.

 In the store where I shop, more than half the produce items are in plastic – either clamshell (more rigid plastic) or flexible bags. Neither type of plastic is recycled effectively. It’s impossible to buy leafy greens or grapes or carrots or mushrooms, or celery or blueberries…the list goes on and on…in the store where I usually shop without the plastic! Usually there are potatoes, squash, broccoli, cabbage, kale, bell peppers, cucumbers, apples, pears, lemons, and oranges from bins where I can use my own bags or keep them unbagged…but none of them are the organic versions. I am beginning to wonder whether organic is worth it with all the plastic around those foods (and maybe used during production to control weeds). Right now, I am skewing toward the food with the least packaging (or no packaging). If I do buy something in plastic packaging, I take it out of that packaging as soon as I get it home!

I’ve started buying eggs in a pulp paper carton (even though they are more expensive) rather than the Styrofoam cartons; not sure why the producers are using Styrofoam since it isn’t a healthy material and does not protect the eggs from breakage very well either.

The picture below is from Life Magazine from November 10, 1947. The groceries in the picture fed a family of 4 (parents and 4-year-old twins) plus their cat. There might not be any plastic in the picture! The meat and bread appear to the wrapped in paper. The eggs are in boxes and there are canned goods. There isn’t much produce (celery, lettuce, radishes, onions, potatoes); the potatoes and onions are in paper bags and the rest is unwrapped.

I’m not advocating reverting to the 1940s – but we should revie the history of food packaging now that we are understanding the downsides of its single-use design that results in environmental contamination. No one wants to be full of plastic and the associated health challenges.

The Arctic is heating up as much as four times as quickly as the global average, due to the burning of fossil fuels, and this extra heat is warping the world’s refrigerator. We can point to the Arctic as a faraway place but the changes there affect the rest of the world.

12/30/2025 Science Daily Why your vitamin D supplements might not be working - Magnesium may be the missing key to keeping vitamin D levels in balance. The study found that magnesium raised vitamin D in people who were deficient while dialing it down in those with overly high levels—suggesting a powerful regulating effect. This could help explain why vitamin D supplements don’t work the same way for everyone and why past studies linking vitamin D to cancer and heart disease have produced mixed results. (I also learned that dark chocolate is a good source of magnesium from this post!)

It is available online here.

12/19/2025 Smithsonian Magazine Flesh-Eating Screwworms Are Creeping Closer to a Comeback in the United States - Roughly 60 years ago, the United States eradicated the New World screwworm, an insect that feeds on living tissue. A concerted effort led by USDA wiped them out by 1966 by releasing sterile male flies and, since female flies only mate once, this strategy helped diminish their numbers until the population collapsed. The agency estimates the eradication of screwworms saves ranchers $900 million per year in lost livestock. But now, the flesh-eating creature appears to be creeping closer to a comeback. Efforts are ramping up to monitor for screwworms and prepare to fight it back again.

12/17/2025 Archaeology Magazine How did the Roman invasion of Britain impact health? - The health of the women and children declined overall during the Roman period, but mainly among those who lived in urban areas. The decline in health in urban areas can be attributed to overcrowding, pollution, limited access to resources, and devastating exposure to lead in Roman infrastructure.

12/17/2926 The Conversation The US already faces a health care workforce shortage – immigration policy could make it worse - America’s health care system is entering an unprecedented period of strain. An aging population, coupled with rising rates of chronic conditions, is driving demand for care to new heights. The workforce isn’t growing fast enough to meet those needs. For decades, immigrant health care workers have filled gaps where U.S.-born workers are limited. Nationally, immigrants make up about 18% of the health care workforce, and they’re even more concentrated in critical roles. Roughly 1 in 4 physicians, 1 in 5 registered nurses and 1 in 3 home health aides are foreign-born.

12/15/2025 Nature Tracing pollution in the lives of Arctic seabirds – Scientists on Svalbard — the largest island of the Norwegian polar archipelago: there used to be sea ice in the fjord in May when we arrived for the start of the season, but we haven’t seen any sea ice since 2009. They are monitoring the presence of polyfluoroalkyl substances (PFASs) in the birds. The years long research has shown that some contaminants transfer to the yolks of the birds’ eggs. High levels of PFASs have been found to lower hatching rates and reduce overall survival rates. In particular, PFASs disrupt hormones and lower fertility rates in male birds.

But renewable energy has made it possible to generate more wealth without producing more emissions. The U.S. and most of Europe, have completely decoupled growth from emissions over the last decade. Fortunes rose, while emissions fell. Together, these countries account for 46 percent of the global economy.

12/12/2025 Science Daily Scientists find dark chocolate ingredient that slows aging - Scientists have uncovered a surprising link between dark chocolate and slower aging. A natural cocoa compound called theobromine was found in higher levels among people who appeared biologically younger than their real age.

12/11/2025 Clean Technica Drones, Diesel, & Policy: Two Countries, Two Agricultural Futures - China’s rapid adoption of agricultural drones is one of the most interesting examples of technological divergence between two major food producers. The contrast is striking. Chinese pilots are now treating an amount of land with drones each year that is larger than the total farmland base, which means multiple drone passes on the same fields to handle weeds, pests, fertilizer and sometimes seeding. At the same time, the United States is advancing a policy coalition that targets DJI with composite national security concerns and proposes to ban the most widely used spray drones in the country. This fight matters because the ban would remove the only cost effective and widely deployed option for seeding and spraying. It would also shut down a path for lower diesel use and lower chemical demand in a sector that does not have many easy ways to cut operating costs.

12/11/2025 Smithsonian Magazine Gas Stoves Are Poisoning Americans by Releasing Toxic Fumes Associated with Asthma and Lung Cancer - A new study, published this month in the journal PNAS Nexus, suggests that gas stoves are the main source of indoor nitrogen dioxide pollution in the United States, responsible for more than half of some Americans’ total exposure to the gas. The gas can irritate airways and worsen or even contribute to the development of respiratory diseases like asthma. Children and older individuals are particularly susceptible to its effects.

Inside tiny nest cavities high into pines, red-cockaded woodpecker (RCW) parents work tirelessly to feed their chicks. They live in family groups where everyone, even older offspring, helps care for the young. That’s what makes them special; they’re cooperative breeders, families bound not just by instinct, but by teamwork. These woodpeckers remind us that recovery isn’t just about numbers. It’s about understanding the subtle, interconnected forces that make life possible in the first place.

Plastics Crisis – Rorra Countertop Water Filtration System

After reading a lot about municipal water quality, I realized that the water filtration I have been using the past few years (Brita Elite) was not good enough. Yes, the filters claimed to remove some microplastics (I guess they would be considered ‘Particulates (Class 1)’, but I was unclear what testing had been done on the filter). Then there were the issues of the filter housing (plastic) and the pitcher it was installed in (plastic). I started looking for possible upgrades.

I opted to replace my Brita pitchers with a Rorra Countertop Water Filtration System. It is a 2.5-gallon countertop unit that has stainless-steel parts. I bought the unit along with a filter subscription since it will probably need a new filter every 90 days. The company has results from NSF and NSF/ANSI accredited testing showing that system reduces over 50+ contaminants including Total PFAS, Lead, Microplastics, and Estrone. It is engineered and manufactured in the US.

The set up was relatively easy once I got it out of the box! There were an outer box and several inner boxes. I am still working to segregate the recyclable parts from the (relatively small) amount that is not cardboard. They recommended washing all the parts with soapy water which was a little daunting because of the size (like a large mixing bowl). I had to watch the video a couple of times about how to get the filter in properly but – in the end – it was easy.

I have enjoyed the Rorra so far although I am thinking about moving it to another location around the sink, so I don’t have to reach all the way over the sink to fill it from the top. I have carafes that I am using to put water in the refrigerator and to carry downstairs for use for tea in my office. I also use the carafes to fill the reservoir as needed. The spigot is very convenient!

Looking back, I am glad I started filtering our drinking water several years ago. The water supply to our house is from our municipality and it is hard to address the potential of plastic water pipes in our city, community, and house (they probably would shed more microplastics they older they are)…or the microplastics that come from the source of water to our city (wells). Now – with the Rorra – we are upgrading that filtering. It is an investment for our long-term health – not eliminating microplastics (since there are so many other sources of microplastics in our environment) but a dramatic reduction in this one source is a good thing.

12/2/2025 Washington Post ‘Everywhere chemicals’ are in our food, decades after scientists recognized dangers - A large body of science has linked phthalates to a variety of serious health conditions, including premature birth and infertility. The costs to society are huge. A 2024 NYU-led study that catalogued health effects from phthalates exposure in the United States — including contributions to diabetes levels and infertility — estimated that dealing with phthalate-related diseases cost $66.7 billion in a single year. Previous Washington Post article on phthalates from last September: The health risks from plastics almost nobody knows about.

12/2/2025 Science Daily Is your gut being poisoned? Scientists reveal the hidden impact of everyday chemicals - Many chemicals designed to act only on one type of target, say insects or fungi, also affect gut bacteria. Some of these chemicals had strong effects. For example, many industrial chemicals like flame retardants and plasticizers -- that we are regularly in contact with -- weren't thought to affect living organisms at all, but they do.

12/7/2025 Clean Technica Your Single-Use Plastic Bottles Are Killing Endangered Sea Turtles - A recent study published in Proceedings of the National Academy of Sciences concludes that plastic ingestion has been documented in nearly 1,300 marine species, including every seabird family, marine mammal family, and sea turtle species. Researchers analyzed data from more than 10,000 autopsies from marine creatures killed by ingesting plastic; they calculated amounts consistent with a 90% likelihood of death:

• 23 pieces (0.098 cm3/cm) in seabirds;

• 29 pieces (39.89 cm3/cm) in marine mammals: and,

• 405 pieces (5.52 cm3/cm) in sea turtles (377 for juveniles).

12/2025 Greenpeace Plastic Merchants of Myth: Circular Claims Fall - After decades of meager investments accompanied by misleading claims and a very well-funded industry public relations campaign aimed at persuading people that recycling can make plastic use sustainable, plastic recycling remains a failed enterprise that is economically and technically unviable and environmentally unjustifiable. (Press release for the document)

12/8/2025 The Conversation PFAS in pregnant women’s drinking water puts their babies at higher risk – Data on all births in New Hampshire from 2010-2019 were analyzed. The 11.5 thousand births that occurred within 3.1 miles of a site known to be contaminated with PFAS and where mothers were served by public water system (well based) were selected for further analysis. PFAS was greater in the water system wells downstream from the site. Births in the area served by wells downstream were 43% more likely to be low-weigh (under 5.5 pounds), 20% greater chance of preterm birth, and 191% greater chance of the infant not surviving its first year. Research was done at University of Arizona.

12/8/2025 Science Daily Humans are built for nature not modern life - Human biology evolved for a world of movement, nature, and short bursts of stress—not the constant pressure of modern life. Industrial environments overstimulate our stress systems and erode both health and reproduction. Evidence ranging from global fertility declines to chronic inflammatory diseases shows the toll of this mismatch.

12/7/2025 Clean Technica The Floating Solar Revolution - Despite this year’s sharp U-turn in federal energy policy, the renewable energy transition continues to branch out in new directions. One emerging factor is the relatively new area of floating solar. The field has already begun to scale up in some regions around the world, and innovative solar firms are carving out new opportunities here in the US as well.

12/7/2025 Science Daily New moonquake discovery could change NASA’s Moon plan - Scientists have discovered that moonquakes, not meteoroids, are responsible for shifting terrain near the Apollo 17 landing site. Their analysis points to a still-active fault that has been generating quakes for millions of years. While the danger to short missions is low, long-term lunar bases could face increasing risk. The findings urge future planners to avoid building near scarps and to prioritize new seismic instruments.

Sustaining Elder Care – December 2025

It’s been a little more than a month since my sisters and I moved my dad to a memory care facility – away from the memory care residence we had moved him to in January 2023. We had decided that the residence no longer met his needs very well; he was spending a lot of time in his room on his own and the staff yelled for him to come to them for medications and meals. I’m looking back over the last month and realizing that there have been some challenges, but the move was worth it.

His new room require some new furnishings because it was bigger and configured differently. For example – the sink did not have surface area around it so we bought a piece that would provide surface area for things like his toothbrush and water glass plus some storage. It makes it easier for the staff to have the towels in the bathroom rather than in the closet! The room was big enough for 2 guess chairs rather than just one and he now has a chest of drawers to supplement the drawers under his bed (and we are not using the drawers under the bed very much now).

He was confused about the new place…anxious that he would not be able to find his way back to his room and forgetful about how to use the key fob to unlock his door. My sisters put seasonal wreaths on his door as do quite a few other resident’s families….so we opted to emphasize the Beagle Welcome sign. His eyesight is not great but perhaps the O of the wreath with the sign underneath is something he can see well enough. He is getting more proficient with the key fob that he wears around his wrist.

He complained about his big toe hurting and we discovered a bruise. He doesn’t remember anything happening that could have caused it. We are assuming he ran into a piece of furniture sometime when he didn’t have shoes on….not that long after he moved into his new place and was unfamiliar with everything. The bruise has disappeared now.

The staff was not used to shaving residents! My dad has an electric razor and the only staff member that knew how to use it was a male! We noticed that the other men in memory care all have beards. My dad is more comfortable now that he has assistance shaving. We discovered that the facility does not require electric razors (rather than old razors that can be a hazard for memory care residents)….perhaps they will change.

On the plus side – the facility consistently cuts up my dad’s food so that he can feed himself, gets him out of his room for exercise and socialization, helps him find his room/open his door as needed, and has taken quick action when we have noticed an issue.

The decorations for Christmas cover a lot of surface area inside my dad’s room right now…and a large television to play landscapes and animal scenes has been mounted above the dresser. I haven’t seen them yet. One of my goals, because of his eyesight and cognitive challenges, is to diplomatically encourage my sisters to declutter as much as possible.

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?

Treadmill Walks

A few years ago, when we moved from Maryland to Missouri, I was reluctant to move our treadmill, but my husband insisted. Now I am glad he did. I am using it daily to increase my daily activity level. There is no excuse to avoid a 30-minute treadmill walk – weather is not a factor! I’ll increase the incline and speed over time – improving my stamina for when I do hike outside. I’m looking forward to being in better shape to enjoy the hikes already scheduled in January and February.

While I walk, I alternate between reading a novel on my iPad or looking out the French door at our deck and hollies…and the neighbor’s trees/roof. Both activities keep it from becoming boring. I’m glad there is a good view to the outside…and that it didn’t require me to move the treadmill from where we had the movers place it!

Vitamin C Rejuvenates Aging Ovaries in Primates - A long-term primate study suggests vitamin C may slow ovarian aging by reactivating antioxidant defenses—though fertility effects remain untested. Oxidative damage contributes to aging not only in ovaries but also in the brain, heart, and kidneys—raising the possibility that similar interventions might benefit other organs.

Rings of Rock in the Sahara - In northeastern Africa, within the driest part of the Sahara, dark rocky outcrops rise above pale desert sands. They are thought to have formed as magma rose toward the surface and intruded into the surrounding rock. Repeated intrusion events produced a series of overlapping rings, their centers roughly aligned toward the southwest. The resulting ring complex—composed of igneous basalt and granite—is bordered to the north by a hat-shaped formation made of sandstone, limestone, and quartz layers. Photo taken from International Space Station.

How your hormones might be controlling your mind - Hormones are chemical messengers released by certain glands, organs, and tissues. They enter the bloodstream and travel around the body, before binding to receptors in a specific place. The binding acts as a kind of biological "handshake" which tells the body to do something. For example, the hormone insulin tells liver and muscle cells to suck up excess glucose from the blood and store it as glycogen. We still don't understand exactly why some people are so sensitive to hormonal fluctuations, while others aren't. We know that hormones impact mood and mental health, but we need to figure out how they do so before we can come up with the proper treatments.

Texas Voters Approve $1 Billion per Year for 'Critical' Water Infrastructure – Wise move by Texas voters; hopefully it will be enough to keep up with the state’s growing population and resulting demand for water. More details here.

How Does Sugar Affect Our Oral Microbiome and Teeth? - Less processed foods, especially those high in fiber, are often less sticky, which decreases bacteria’s ability to adhere and overgrow at a surface. Additionally, the fiber acts like miniature brushes. “These fibers constantly remove plaque from your tooth surfaces. The additional chewing of these types of foods also increases saliva production, which washes out the oral cavity, removing excess bacteria from the mouth surface to limit the formation of biofilms. Meanwhile, additional sugar from candy and other sweet products disrupts this whole community. Not only are these processed foods stickier, giving the bacteria a place to latch onto, but they also form biofilms.

How Satellite Imagery Reveals Plastic Pollution Hotspots in the Ocean - Plastic pollution isn’t just a sad environmental story we scroll past on the news anymore; it has become a personal health emergency. It is a genuinely scary reality that microplastics, those tiny, unseen fragments, have made their way into our lungs and bloodstreams. To grasp the sheer scale of this threat, researchers are turning to Sentinel satellite imagery, utilizing it as an essential “eye in the sky” to track exactly where these hazardous accumulation zones are growing. However, mapping is just the diagnostic tool; the ultimate cure lies in fixing land-based waste management.

The photos showing why pink dolphins are the Amazon's 'great thieves' - As fishermen cast their nets into the river, suddenly a sleek pink shape emerged from the depths, swimming toward the trapped fish. Moving quickly, the creature – an Amazonian pink river dolphin – poked holes in the net and stole a catfish. Known locally as boto in Portuguese and bufeo in Spanish, the pink river dolphin is a funny sight. With its melon-shaped head, rose-colored skin, and slender, hundred-toothed snout, it is the largest freshwater dolphin in the world, growing up to 2.5m (8.2ft) long and weighing as much as 200kg (440lbs). Four types of pink river dolphins live in the Amazon River basin. All of them are endangered, facing significant population declines in recent decades due to hunting, entanglement in fishing nets, pollution and droughts.

Half of heart attacks strike people told they’re low risk - A new study led by Mount Sinai researchers reports that commonly used cardiac screening methods fail to identify almost half of the people who are actually at risk of having a heart attack. People who appear healthy according to standard assessments may already have significant and silent atherosclerosis. Because of this, depending solely on symptoms and risk calculators can delay detection until meaningful prevention is no longer possible. Doctors should shift their focus from detecting symptomatic heart disease to detecting the plaque itself for earlier treatment, which could save lives.

Clogged Glymphatic System Linked to Dementia Risk - The brain’s built-in clearance system, called the glymphatic system, removes toxins from the brain through the flow of cerebrospinal fluid (CSF) via minuscule channels that trace blood vessels. Scientists have suspected that the glymphatic system may play a role in processes such as sleep and recovery from traumatic brain injury. MRI scans from nearly 40,000 people revealed biomarkers linked to defective toxin clearance in the brain predicted the susceptibility to dementia later in life.

Ansel Adams Photos Capture Daily Life Inside Japanese Internment Camps During WWII - The establishment of Japanese internment camps is arguably one of the darkest moments in American history. Between 1942 and 1946, about 120,000 people of Japanese descent were forcibly relocated into these concentration camps. This was done out of unfounded suspicions that Japanese Americans might act as saboteurs or spies following the attack on Pearl Harbor in 1941. In 1943, celebrated American photographer Ansel Adams visited the Manzanar War Relocation Center in California, creating a timeless document of the daily life on this site. The 244 photo collection can be browsed on the Library of Congress website.

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.

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.

Spotted Lanternfly Biology and Lifecycle – Missouri is trying to stop them from gaining a foothold in the state….but it will take a lot of vigilance. The invasive insects are already in Illinois and could move into Missouri very easily – particularly as egg masses on vehicles. In the current infestations, spotted lanternfly has shown to have one generation per year consisting of four nymphal stages, an adult stage, and overwintering as egg masses.

Could Non-Invasive Colon Cancer Screening Replace Colonoscopies? – It would be great if these could work….colonoscopies are invasive tests….but, for now, they are the only choice for a reliable screening for colon cancer.

13 Non-Toxic, Plastic Free Electric Kettles for a Healthy Cup – A plastic free electric kettle is on my wish list for this year. It will be used a lot in my office.

Reindeer Hunting Artifacts Emerge from Melting Ice in Norway - Melting ice in Norway has revealed a 1,500-year-old reindeer trap, preserved beneath centuries of snow and ice layers. Archaeologists uncovered wooden mass-capture fences, marked antlers, weapons, and a unique decorated oar from the site this year.

Why are thyroid cancer cases increasing across the world? - We're likely observing a multifactorial phenomenon that includes environmental, metabolic, dietary and hormonal influences, possibly interacting with underlying genetic susceptibility.

A Bird in Mourning Wins the 2025 European Wildlife Photographer of the Year Contest – Great photos!

Anxiety is one of the world’s most common health issues. How have treatments evolved over the last 70 years? – I was surprised that no new drugs have been approved since 2004. While existing treatments can be very effective for some people — in fact, life-changing for some — we still have some way to go to develop effective treatments for everyone who struggles with an anxiety disorder, and ensure these treatments are available to them.

What a baby's first poo can tell you about their future health - T he Baby Biome study, which aims to understand how a baby's gut microbiome – the trillions of microbes living in their digestive tract – affect their future health. Babies born vaginally seem to inherit most of their bacteria from their mother's digestive tract; babies born via C-section had more bacteria associated with hospital environments.

From Ruins to Reuse: How Ukrainians Are Repurposing War Waste - Russian bombardments have generated more than a billion tons of debris across Ukraine since 2022. Now, local and international efforts are meticulously sorting the bricks, concrete, metal, and wood, preparing these materials for a second life in new buildings and roads. 

Our Plan to Restore the Gulf Coast for People and Wildlife - America’s Gulf Coast stretches over 1,700 miles and is home to 15,000 species of fish and wildlife, making it one of the most biodiverse areas in the country. It’s also one of the fastest-growing—the counties that border the Gulf are home to approximately 65 million people. Despite the challenges, including federal funding cuts to states, shifting political priorities and increasingly destructive storms and flooding, the National Wildlife Federation remains optimistic about what we can achieve in the next five years and the decades to come.

Inflammation Starts Long Before the Pain in Rheumatoid Arthritis - Millions of people around the world suffer from rheumatoid arthritis, an autoimmune disorder that causes debilitating joint swelling and pain. New research reveals more early biomarkers for rheumatoid arthritis which may lead to ways to prevent, rather than treat, the disease.

Bottled Water is a Major Source of Microplastics - Nano- and microplastics have been linked in studies to inflammation, immune dysregulation, cardiac events, and metabolic disruptions. Though human data are still emerging, evidence also suggests a connection to respiratory disease, reproductive issues, and even neurotoxicity. 

Traces of Opium Detected on Egyptian Alabastron - Traces of opium have been detected in an ancient Egyptian alabaster vase held in Yale University’s Peabody Museum. It had been previously suggested that such vases held perfumes or cosmetics for royal elites.

Gum disease may quietly damage the brain - Researchers observed that participants with gum disease had significantly more white matter hyperintensities, even after accounting for other risk factors. The findings hint that chronic oral inflammation could subtly impact the brain, especially in older adults.

6 Best Non-Toxic Lunch Boxes That Don’t Shed Microplastics – I am using my glass left-over containers….but I don’t need to carry my lunch every day!

How Air Pollution is Aging People Faster - Long considered mainly a threat to the lungs and heart, air pollution is now emerging as a driver of biological aging at the molecular level. With air pollution’s role in accelerating aging, researchers are exploring interventions ranging from reducing emissions to using protective measures. Alongside identifying the effects of different pollutants, scientists are now investigating the biological mechanisms through which air pollution accelerates aging.

Domestic Solar Manufacturing Booms During Trump Administration with Entire Solar Supply Chain Reshored - New data from the Solar Energy Industries Association (SEIA) shows that the entire solar supply chain has been reshored and U.S. manufacturing capacity has grown across every segment of the solar and storage supply chain. With the news of Hemlock’s new ingot and wafer facility coming online in Q3, the United States now has the capacity to produce every major component of the solar supply chain.

Covid 2020: Where cruise ships went to die - Aliağa Ship Breaking Yard in Turkey is the fourth-largest facility in the world for breaking down large ships, and as the effect of cancelled cruises began to bite, it's where many of the cruise companies sent their huge ships to die.

China Has Added Forest the Size of Texas Since 1990 - In many wealthy nations — the U.S., Canada, Russia, and much of Europe — forests are making a comeback, according to the U.N. assessment. As India and China become more developed, they too are seeing forests return. Even as fires and drought destroy some forest, on balance, these countries are adding trees. Over the last three and a half decades China has planted roughly 120 million acres of forest, according to U.N. figures, much of it added to contain the spread of deserts.

How Do Cadaver Dogs Recognize Human Remains? - Someday scientists will understand how cadaver-associated molecules bind to receptors in dog noses and how this binding, in turn, affects the molecules’ structure and chemistry. Knowing the exact stimuli that cadaver dogs pick up may also advance researchers’ efforts in building “electronic noses.” These chemical sensors are not meant to replace cadaver dogs but rather as stand-ins that could go to places that are inaccessible or too dangerous for dogs.
