9/15/2025 NIH National Library of Medicine Microplastics in Drinking Water: A Review of Sources, Removal, Detection, Occurrence, and Potential Risks - Microplastics in drinking water systems exhibit multi-source input characteristics, originating from environmental infiltration into water sources; leaching from materials in water distribution systems; migration from bottled water packaging interfaces; and re-release during water treatment processes. The potential hazards of MPs remain a critical concern. Future work needs to integrate research from environmental science, toxicology, and public health to clarify the dose–effect relationships of MPs, improve risk assessment systems, and promote technological innovation and policy regulation to effectively ensure drinking water safety and public health.

12/21/2025 Plantizen Winter Road Salt is Making Waterways Toxic to Wildlife - Salt used to keep roadways free of ice and snow is accumulating in waterways, causing dangerously high salinity levels in water bodies in Pennsylvania, New Jersey, and Delaware - well above the healthy accepted drinking water standard for people on a low-salt diet.

12/22/2025 ScienceDaily This fish-inspired filter removes over 99% of microplastics - Washing machines release massive amounts of microplastics into the environment, mostly from worn clothing fibers. Researchers have developed a new, fish-inspired filter that removes over 99% of these particles without clogging. The design mimics the funnel-shaped gill system used by filter-feeding fish, allowing fibers to roll away instead of blocking the filter. The low-cost, patent-pending solution could soon be built directly into future washing machines.

12/24/2025 The Prairie Ecologist Photos of the Year – From Chris Helzer: “Well, we’ve almost made it through 2025. To say it has been an eventful year seems like a massive understatement. As I’m sure is true for many of you, I tried to manage stress and anxiety by spending time in nature – exploring with curiosity and wonder and giving myself a break from the rest of the world for a little while. It helped.”

12/24/2025 ScienceDaily Scientists reverse Alzheimer’s in mice and restore memory - The damaged brain can, under some conditions, repair itself and regain function. )ne drug-based way to accomplish this in animal models in the study, and also identified candidate proteins in the human AD brain that may relate to the ability to reverse AD and opens the door to additional studies and eventual testing in people. The technology is currently being commercialized by Glengary Brain Health, a Cleveland-based company.

12/22/2025 The Conversation Everyday chemicals, global consequences: How disinfectants contribute to antimicrobial resistance - During the COVID-19 pandemic, disinfectants became our shield. Hand sanitizers, disinfectant wipes and antimicrobial sprays became part of daily life. They made us feel safe. Today, they are still everywhere: in homes, hospitals and public spaces. But….The chemicals we trust to protect us may also inadvertently help microbes evolve resistance and protect themselves against antibiotics.

10/14/2025 All about Vision How microplastics affect your eyes, and what you can do - Microplastics don't go away. They just get smaller and smaller over time. They can come from everyday things like bottles, tires, fabrics and personal care products. Studies have found microplastics on and even inside people's eyes.

12/25/2025 BBC The best nature photography of 2025 - From the depths of the oceans to deserts, mountains and the remote Amazon, this year's most extraordinary nature photography brings us glimpses of the diversity and awe of the natural world. This year we meet acrobatic gorillas, maritime lions and grinning bears. 

12/22/2025 Smithsonian Magazine This Mama Polar Bear Adopted a Young Cub - The bears need all the help they can get these days with climate change. If females have the opportunity to pick up another cub and care for it and successfully wean it, it’s a good thing for bears in Churchill.

12/19/2026 Artnet Inside the 6,000-Year-Old Underground Temple Where the Walls Literally Sing - Ħal Saflieni Hypogeum, an ancient, underground burial complex on the Mediterranean island of Malta. Built around 4,000 B.C.E. this subterranean burial ground amplifies sound at a soothing frequency.

Too much salt can hijack your brain – In a study using rats, researchers showed that a high-salt diet activated immune cells in a specific brain region, causing inflammation and a surge in the hormone vasopressin, which raises blood pressure. Researchers tracked these changes using cutting-edge brain imaging and lab techniques that only recently became available.

Two-Thirds of River Trash Is Plastic - Recent research conducted at the University of California–Santa Barbara found that rivers have far too much plastic in them. 1.95 million metric tons of plastic — the weight of 5.3 Empire State buildings — travels down rivers worldwide every year. It comes from littering, illegal dumping, leakage from landfills…and is mobilized across landscapes, through urban drainages, and into waterways by wind and rains. And it isn’t harmless. Microplastic in rivers accumulates in food sources, and direct exposure via inhalation and consumption of water leads to direct accumulation in our bodies. Macroplastic in rivers affects our infrastructure and communities by blocking drainages, exacerbating flood risk and damage, and negatively affecting tourism, fisheries, and shipping. And plastic also impacts the river ecosystem and biodiversity via wildlife entanglement, ingestion, and smothering, leakage of chemical additives, and transport of non-native species and pathogens. Plastic continues to break down into smaller and smaller pieces. As microplastic breaks down, it becomes nanoplastic…which might be the most dangerous to health of living things – including humans.

'I had no idea it would snowball this far': Why a Brazilian favela facing eviction decided to go green - Favelas – or Brazilian slums – are widespread informal settlements often situated on the periphery of major cities such as São Paulo and Rio de Janeiro. They are home to low-income populations and can be built precariously on unstable land such as slopes and hills. They are often underserved in formal infrastructure – meaning they can be especially vulnerable to climate impacts and risks such as landslides – and commonly don't have access to public services such as sanitation. The post is about one favela that cleaned up trash/waste…built a garden.

These Lizards Have So Much Lead in Their Blood, They Should Be Dead. Instead, They’re Thriving – Brown anoles (non-native…native to Caribbean) around New Orleans since the 1990s. They are not physiologically impaired by the high levels of lead in their bodies.

Canadian Archaeologists Excavate Homestead of Black Rancher John Ware – He arrived in Canada in 1882…herding 3,000 head of cattle and settled near Millarville, Alberta.

In Scotland, Whale Strandings Have More Than Tripled - Over the past three decades, the number of whale strandings in Scotland has grown dramatically. Scientists say pollution and industrial noise may be driving the losses.

What Is High-Quality Prairie Anyway? - What are the criteria we should use for evaluating prairies?

Pic for Today – I saw more Jewelweed in Maryland than I do in Missouri….but always enjoy spotting it…I couldn’t resist adding this post to the gleanings this week.

113-Year-Old Bathhouse Being Restored at Hot Springs National Park – Glad the Maurice Bathhouse is going to be rehabilitated; it has been closed since 1974.

Scientists finally crack the secret to perfect chocolate flavor - Scientists have decoded the microbial and environmental factors behind cacao fermentation, the critical process that defines chocolate’s taste.

Study investigates source of Amazon’s “Dark Earth” – Created intentionally? It is less acidic than surrounding soils…probably from the addition of ash.

New York City Greenery Absorbing All Traffic Emissions on Many Summer Days – There is a lot more greenery that previously thought…looking beyond parks to modest backyards, shrubbery growing in vacant lots, and trees dotting city sidewalks. That’s good for the summer when everything is green and growing….but it also implies that winter air quality is problematic.

‘Stomp’ Performers Hang Up their Garbage Lids – After 3 decades off-Broadway. Watch the video!

Riddle solved: why is Roman concrete so durable? – It wasn’t just volcanic ash that made Roman concrete better…lime clasts play a self-healing role!

Why is every parking lot covered with solar panels? – Evidently Michigan State has done it…hopefully other universities and big box stores do similar projects. 

How the war in Ukraine is killing marine mammals – The dolphins that were washing up on the shore of the Black Sea prior to the war were few and usually had markings suggesting entanglement in fishing gear.  The theory about the increased number appearing now, without marks, is that the dolphins are experiencing acoustic trauma from the increased use of sonar by Russian submarines.

Climate impact labels on sample food menu had strong effect on food selection – A study done by Johns Hopkins. The result indicate that this kind of labelling could promote more sustainable choices….and have positive health benefits as well!

Aerial Photos Capture the Abstract Beauty of Salt Ponds – From a new book….with images and background about these man-made landscapes.

Great Salt Lake will disappear in 5 years without a massive ‘emergency rescue’ – My husband and I visited the lake back in 2008. The pictures in the article are so different that I needed the captions to recognize the place. The lake was already shrinking in 2008 but the shrinking has increased with long term drought and increased population diverting more water that would otherwise flow into the lake. Aside from the ecological collapse if the lake goes dry, the dust from the dry lakebed is kicked up by winds and can damage lungs/exacerbate other respiratory illness. This does not bode well for public health in Salt Lake City.

Painted skulls from Peru’s Chincha Valley analyzed – The red paint on the skulls was not all the same on all the skulls: some have iron-based ochres and others have mercury-based cinnabar….the red paint on one of the skulls was a combination of the two!
