Gleanings of the Week Ending November 8, 2025

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.

Childhood Exposure to Plastic Raises Lifetime Health Risks - Scientists analyzed decades of research into the impact on pregnant mothers, fetuses, and children of three chemical additives — phthalates, bisphenols, and perfluoroalkyl substances — that make plastic more flexible, more rigid, or more resistant to heat or water. Early exposure to these chemicals can leave children at greater risk of heart disease, obesity, infertility, and asthma well into adolescence and adulthood. Plastic additives are also believed to affect the development of the brain, with studies linking the chemicals to lower IQ, ADHD, and autism. The widespread use of plastic is exacting a deepening toll, with Americans paying an estimated $250 billion yearly to treat ailments linked to plastic.

Scientists Resurrect 40,000-Year-Old Microbes from Alaskan Permafrost. What They Found Raised Worries About the Future of a Warming Arctic - Roughly 40,000 years ago, microbes went dormant in a rock-like layer of frozen soil near the future site of Fairbanks, Alaska. Now, researchers have successfully “reawakened” the tiny creatures, raising concerns about how those microbes could increase greenhouse gas emissions in a warming Arctic.

The Butterflies of Marinduque: Small Wings, Big Changes - Marinduque supplies about 85% of the Philippine’s butterfly pupae exports. Beyond trade, butterflies have become symbols of livelihood, culture, and conservation for the island.

A simple fatty acid could restore failing vision - Retinal polyunsaturated fatty acid supplementation reverses aging-related vision decline in mice….and systemic lipid supplementation could potentially counteract the effects of age on the immune system. But will in work in humans…that’s still TBD.

Is it possible to lose weight on an 'Ozempic' diet? – Study findings suggest that there's some kind of mechanism we can tap into to restore healthy eating without drugs by limiting the sense of reward and achieving a sense of satisfaction without overeating.

This Chilling Recording Reveals Large Bats Catching, Killing and Eating Birds Midflight – How the greater noctule bat, the largest bat species in Europe, catches and eats its prey.

Fentanyl overdoses among seniors surge 9,000% — A hidden crisis few saw coming - Fatal overdoses among adults 65 and older involving fentanyl mixed with stimulants such as cocaine and methamphetamines have risen dramatically, climbing 9,000% in the past eight years. The rate now mirrors that seen in younger adults. The rise in fentanyl deaths involving stimulants in older adults began to sharply rise in 2020, while deaths linked to other substances stayed the same or declined. Cocaine and methamphetamines were the most common stimulants paired with fentanyl among the older adults studied, surpassing alcohol, heroin, and benzodiazepines such as Xanax and Valium.

Billions of bacteria lurk in your shower, just waiting to spray you in the face - should you be worried? - For most people the risk of catching a bug from your shower head is low, particularly if you are using it frequently. Running the shower for 60-90 seconds, allowing it warm up before stepping under the spray, also means it is also doing some useful work in that time, flushing out many of the microbes. This is particularly advisable after a holiday or any long gap between using the shower. Regular cleaning by running very hot water through the shower, along with descaling your shower head or soaking it in lemon juice can help to disrupt the microbes living there and control the size of biofilms.

Dolphins may be getting Alzheimer’s from toxic ocean blooms - Dolphins washing up on Florida’s shores may be victims of the same kind of brain degeneration seen in humans with Alzheimer’s disease. Researchers discovered that cyanobacterial toxins—worsened by climate change and nutrient pollution—accumulate in marine food chains, damaging dolphin brains with misfolded proteins and Alzheimer’s-like pathology. Since dolphins are considered environmental sentinels for toxic exposures in marine environments there are concerns about human health issues associated with cyanobacterial blooms. In 2024, Miami Dade County had the highest prevalence of Alzheimer's disease in the United States.

Nigeria, a Major Oil Producer, Sees Beginnings of a Solar Boom - For Nigerians, the cost savings from ditching diesel mean that a solar panel pays for itself within six months. Homeowners who can afford the up-front costs are installing rooftop solar in large numbers, while some villages are setting up community solar and battery projects. Solar is making huge gains in Nigeria, with imports of Chinese solar panels growing by two-thirds between June 2024 and June 2025. n Pakistan, high fuel prices, a byproduct of the Ukraine war and the loss of a fuel subsidy, have spurred the mass adoption of solar.

Stunning Microscope Videos Highlight Self-Pollination, Algae and Tumor Cells in the Nikon Small World in Motion Contest – The first and fifth were my favorites of these short videos.

Bird Photography Boat Tour

Our second day of the Whooping Crane Festival continued with another boat tour after returning from the King Ranch and a quick lunch. The afternoon emphasis was on bird photography. The difference was subtle. The guide did suggest some settings to accommodate photographing in the very bright environment of a sunny day. I opted to take the normal opportunities to photograph birds as usual…but then took some photographic challenges too.

I started before we even boarded the boat. Grackles were taking snack packaging out of a trash can. The female seemed to be unimpressed with her partner’s antics.

I attempted to get a double-crested cormorant taking off from the water…managed to capture the form and splashes of water but the eye doesn’t show….plenty of room for improvement.

There were terns (probably common terns) diving toward the water for fish. I tried pointing my camera in that direction and pressing the button to take multiple pictures in fast succession. It was hard to hold the camera still as the boat moved! The shape of the bird as it nears the surface of the water was something I couldn’t study until I looked at my pictures on a bigger screen. This was my first attempt at photographing feeding terns!

The back of a white-tailed hawk – the only sighting of this species of the trip. It isn’t a great picture in the traditional sense….but it does tell a story. The bird was sitting in dead mangroves; the mangroves died during very cold weather a few years ago and recovery is slow; hurricane damage to the Aransas area would be even worse than before if one comes through before the mangroves can become established again.

The birds always seemed to be a little further away than optimal…and the boat was rocking. But I took pictures anyway: white ibis, little blue heron, osprey, great egret, and great blue heron. I tend to take photographs rather than make notes about what I am seeing…it’s easier with the camera already in hand!

And then there were the reddish egrets… with their pink and black bill.

And finally one started foraging…moving rapidly in the shallows. It seemed to veer off suddenly…something there that the bird didn’t expect?

I took group pictures of birds on small islands in the water…always interesting to see how many I can identify on my big screen later. In the one below, I see brown pelicans (adult and juvenile), American white pelicans, cormorants (double crested probably)…all in the foreground.

As I zoomed in on birds that were not in a group I noticed a black skimmer and some Caspian terns.

It’s always a thrill to see a bird I would not have seen without being on a birding field trip like this red-breast merganser. It was a single bird…swimming rapidly away from the boat…and I probably would not have noticed it without someone pointing it out. I’m not sure it was the guide or another participant that noticed it.

The same was true for another black-crowned night heron.  I photographed one on the King Ranch in the morning! I was pleased that I was able to find and focus on the bird more easily than many of the others on the boat.

The light began to change as we neared the end of the day. There were enough clouds to try a non-bird landscape shot of the water the sky…a bit of land at the horizon.

I changed a setting on my camera to try an artsy image of a cormorant and the shore as we came back toward the dock.

And then the boat stopped just before we got to the dock….for dolphins. I couldn’t top my husband’s dolphin picture in the bow wave of the big ship, but it was fun trying to anticipate when they would surface!

And then one last picture before we got off the boat! It was a great second day at the Whooping Crane Festival. The next morning was an early one….getting on a boat at 6 AM to see Whooping Cranes in the Aransas National Wild Life Refuge. We headed to the hotel for an early evening to be ready for it.

Sunset Dolphin Cruise

The second activity of the Whooping Crane Festival for us was a Sunset Dolphin Cruise…in the late afternoon of the first day of the festival.

The angle of the sun made the water look bluer that it did earlier in the afternoon. There were plenty of brown pelicans about.

The moon was visible in the clear sky…above shoreline construction cranes.

Cormorants were using structures further above the water than earlier in the day.

I took several pictures of the Aransas Pass Lydia Ann Lighthouse as we passed by.

The high point of the trip was dolphins surfing the bow wave of a big ship coming through the channel. My husband managed to get a picture of three leaping out of the water!

By the end of the cruise the sun was sinking fast into the haze.

We headed to the hotel to rest up…be prepared for the early start of our second day at the Whooping Crane Festival.

Gleanings of the Week Ending January 14, 2023

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

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!
