Gleanings of the Week Ending January 03, 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. (Note: I have changed the format to include the date and source of the article.)

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.

Onyx Cave

After Cosmic Caverns and lunch, we opted to see a second cave. It wasn’t on our original itinerary, but the rain had forced a change in plans. Onyx Cave became our afternoon destination. It has been famous since 1891…and there is considerable damage that has accumulated over the years.

The first part of our tour was self-guided with headphones that described things at each stop. The second part was a guided tour.

The lighting in the cave was not as good as in other caves I have visited, including Cosmic Caverns, but it is still possible to get reasonable pictures. Sometimes the damage (sawed off stalactites and soda straws) revealed the inner structure of the formations. The cave is damp but many of the formations have been touched often over the years…so they have a dry look.

I think my favorite cave tour this year is Onondaga Cave that I toured back in April (posts one and two).

Cosmic Caverns

Last weekend we made an overnight trip to Arkansas as an early birthday celebration for my daughter. We picked her up at 8 AM at her house in Springfield MO (seeing what she means about her native plant garden being overwhelmed by grass).

Our plan had been for a hike at a state park in the morning, but it started sprinkling on the way there and was raining hard when we got to the park. We quickly decided to head to Cosmic Caverns. The parking lines there are made with bat stencils!

There were steep steps that reminded me of caves I toured as a child.  Now many caves have replaced their stairs with long ramps that make the cave more accessible.

The cave lighting was good, but the guide’s flashlight was sometimes needed to highlight features…and the black light flashlight provided a different perspective of some of the formations.

The cave was discovered in 1845 and there is damage that has occurred over the years. It is still a beautiful place to visit, and I enjoyed seeing how well my phone captured the cave formations.

Fantastic Caverns

Fantastic Caverns is a great place to visit in the summer since the cave is 60 degrees all year long. We arrived a little before 10 AM and got tickets for 10:30 since there was a large school group at 10. During the wait, I bought some goat milk soap in the gift shop and looked at the mineral, quilt, and other artifact displays in the visitor center.

At 10:30 we walked out of the visitor center, down a ramp, and got on the tram that would take use through the cave.

I managed to take more pictures of the entrance (man-made) as we started our tour than I did during my previous visits. There is a lot of Viriginia Creeper on the rock face.

I used the ‘night scene’ setting on my Canon Powershot SX730 HS (my oldest camera!) because it is easier to hold than my phone. The lighting in the cave is relatively good and the guide illustrated several ways lighting of the cave has changed over the years. This was my third visit, and this guide was probably less experienced that my previous visits. (click on any image below to see a larger version).

This was the first visit to the cave for my daughter and the second for my husband. We all agreed that it is an excellent option for visitors that are not physically able to do other caves. We are already planning a visit to a cave that offers ultraviolet light tours…but that requires being able to walk around on your own with a headlamp and googles!

Zooming – April 2025

Springtime photography….is April the best month? It seems like that might be true this year. The photographs were taken at the Springfield Botanical Gardens, my yard, the Missouri State University Campus, my daughter’s yard, Onondaga Cave, and 2 volunteer activities. There were so many images to choose from; I selected 23. I used three different cameras – iPhone 15 Pro Max, Canon Powershot SX730 HS, and Nikon Coolpix P950. Enjoy the slideshow!

Onondaga Cave (2)

Onondaga Cave is a wet cave. That means many of the formations are still active and the air in the cave is very moist. There is an airlock where the tour begins and ends. There are salamanders in the cave, but their numbers have declined with the bats (White Nose Syndrome); the salamanders eat the bat droppings and there are not enough to sustain as many salamanders and before. We didn’t manage to see any.

There is a river that runs through the cave. At one point you can hear the water moving but when you look at it from above it seems very still! They know where the water goes but not where it comes from!

On the way home we stopped at Bennett Spring State Park near Lebanon MO. It was raining so the only picture I took was of a painted glass window! We drove down to where the spring emerges and then back to I-44 along a road through the forest….lots of dogwoods in bloom in the understory. It was a grand finale to the day trip even with the rain!
