Gleanings of the Week Ending July 18, 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.

07/06/2026 Clean Technica Fixing Climate Communications Part 1 - Make consequences such as your insurance bill, your home, and your children’s health urgent and tangible; make the cause concrete by anchoring every message to pollution rather than climate change; and make the cure feel expansive rather than restrictive. Reaching enough people to sustain the transition will require a delivery infrastructure built around genuine community engagement, economically grounded wins, and a willingness to hold accountable the interests that have made this conversation harder than it needs to be.

07072026 Clean Technica Climate Communications — From Losing the Argument to Winning It Part 2 - Telling the climate story with the value proposition of cost, risk management, improved operational performance, supply chain resiliency, and long-term enterprise value is a winning one. It’s a strategy that appeals to the C-suite, is durable, and can be couched in shareholder returns.

07/06/2026 Smithsonian Magazine These 11 Wildlife Images from the Ocean Conservancy’s Photography Contest Showcase the Wonder of Earth’s Waters - The annual contest received more than 1,000 photographs of marine wildlife and habitats this year. The ones that rose to the top were portraits of ocean wildlife, and I think that’s because we crave to see and connect with animals on an interpersonal level.

07/07/2026 The Conversation 3.1 billion‑year‑old rocks in Australia reveal a forgotten chapter of Earth’s water cycle - We learn the water cycle in school as a story of evaporation and precipitation. But Earth runs a second, far slower one deep beneath our feet. On the ocean floor, seawater seeps into the oceanic crust and reacts with the rock, becoming chemically bound inside its minerals, locked into their crystal structures rather than sitting as free water. Over millions of years, sinking tectonic plates carry these water-bearing minerals down into the mantle, the hot rock layer beneath the crust. This sinking of one plate beneath another is called subduction, and volcanoes eventually breathe the water back out. The deep water cycle moderates Earth’s water budget. At the surface, it keeps the oceans from drying up or drowning the continents, while in the interior, it changes how the mantle melts and builds continents.

07/06/2026 NWF Blog Marine Animal Quiz: It’s Plastic Free July! - Take the time to learn more about how plastic pollution in the oceans of the world harms marine life and consider action steps you can take to reduce your plastic waste footprint.

07/04/2026 ScienceDaily The secret to healthy aging may be hidden in your blood - A new study found that centenarians have a unique chemical "fingerprint" in their blood that sets them apart from normal aging, including unusual patterns of bile acids and steroids linked to longer survival.

07/03/2026 Planetizen Lake Powell reaches lowest water level on record - Currently, Lake Powell is around 24 percent full. The last time it was completely full was in 1983. Since then, water levels have fluctuated, but in 2026, they have fallen to a critical point. And there are multiple concerns if the water levels continue to drop. One includes reaching "dead pool," the point at which water levels are so low that water can no longer move across the dam and into the Grand Canyon, which would cause significant ecological impacts and reduce the capacity for hydroelectricity. 

07/03/2026 Yale Environment 360 In Overfished Adriatic Sea, Dolphins Look to Trawlers for Food - Off the eastern coast of Italy, large numbers of bottlenose dolphins are looking to fishing trawlers as a source of food, a sign that dolphins may be struggling to feed themselves in waters depleted by overfishing. Dolphins may also suffer hearing damage that results from chronic exposure to the noise of trawlers. It is risky behavior. However, finding sufficient prey away from trawlers in an overfished sea may be too difficult. It appears that for these animals, taking the risks is better than going hungry.

7/2/2026 Smithsonian Magazine Earth Might Be Home to 20 Million Insect Species—More Than Three Times as Many as Previously Thought – Only about one million species have been named and described, meaning up to 95 percent of the planet’s insect diversity might remain a mystery…. With more than 40 percent of known insect species threatened with extinction. “The library is being burned before the books can be read.”

Gleanings of the Week Ending June 27, 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.

06/17/2026 Science Daily Scientists say most of what’s in your food is still a mystery - Most chemicals in food are invisible to us in terms of research. We consume them every day, but we have little idea what they do. Projects such as the Foodome Project are now attempting to catalogue this hidden chemical universe. More than 130,000 molecules have already been listed, linking food compounds to human proteins, gut microbes and disease processes. The aim is to build an atlas of how diet interacts with the body, and to pinpoint which molecules really matter for health.

06/17/2026 The Conversation Levels of ‘forever chemicals’ in dolphins and whales are rising globally - Whales and dolphins inhabit some of the largest and seemingly most pristine environments on Earth, from tropical coastlines to Antarctic waters. Yet even they cannot escape PFAS – persistent “forever chemicals” that leak from our homes, factories and waterways into the sea. Whales and dolphins inhabit some of the largest and seemingly most pristine environments on Earth, from tropical coastlines to Antarctic waters. Yet even they cannot escape PFAS – persistent “forever chemicals” that leak from our homes, factories and waterways into the sea. Some dolphin studies have reported changes in immune-related markers associated with PFAS exposure. The highest concentrations tended to be found in coastal dolphins and porpoises, suggesting animals living near urban and industrial areas face greater exposure.

06/15/2026 Smithsonian Magazine Venus Flytraps Snap Their Traps Shut in Less Than a Second - A team reports that the chomping motion happens when rigid walls of cells on the leaves’ outer surface suddenly soften. The findings provide new insights into plant biology and could inspire new robotic designs.

6/16/2026 The Conversation Microplastics are everywhere in Pennsylvania’s water – but the tide may be turning - Microplastics are nearly everywhere, their concentration in sediment has been doubling every 20 years, and some of the most common types are among the most toxic. More than 80% of mismanaged plastic waste - plastic that’s littered, dumped or otherwise not properly contained - is estimated to be transported by rivers to coastal environments. What can you do to decrease your exposure to microplastics and help decrease their spread? You can stay informed about which plastics carry the greatest health risks and check the recycling number on the bottom of containers before you buy. You can also swap out single-use plastic cups, straws and food containers for alternatives, such as glass, stainless steel or unbleached paper.

06/11/2026 NASA Air Pollution’s Daily Pulse Over the Northeast - More than 35 million people live along the New York–Washington corridor and breathe the region’s air. While air quality has improved significantly in recent decades, outbreaks of ground-level ozone remain common, particularly in the warm summer months, when the chemical reactions that produce the pollutant accelerate and stagnant air allows ozone to accumulate. A reminder of this seasonal phenomenon came earlier than usual in 2026, when a mid-May heat wave prompted the New York State Department of Health and the New York Department of Environmental Conservation to issue a health advisory on May 17 over concerns about ozone.

06/13/2026 Clean Technica Solar & Storage Provide Over 90% of All New Power Added to the U.S. Grid in Q1 - The United States added 7.8 gigawatts (GW) of new solar capacity in the first quarter of 2026, surpassing 6 million cumulative installations as solar remained the leading source of new power added to the grid. Despite changing tax policy and regulatory actions targeting clean energy, solar and energy storage represented 91% of new capacity installed in Q1 as utilities, homeowners and businesses seek energy security amid global gas and gas turbine supply disruptions.

03/17/2026 National Geographic To study microplastics, Cassandra Rauert first had to build a plastic-free lab. It wasn't easy - An air-locked, 250-square-foot facility built almost entirely from stainless steel and nicknamed “the submarine”—though it feels less like a sub and more like a starship from a galaxy where plastic never took over modern life. Known as the Minderoo Plastics and Human Health Laboratory

06/09/2026 Science Daily An invisible forever chemical rain is falling across the planet - Researchers found that refrigerants and certain anesthetic gases have generated more than 335,000 tons of trifluoroacetic acid (TFA), a highly persistent "forever chemical," that has been deposited across Earth's surface since 2000. The pollutant is now showing up everywhere from rainwater to remote Arctic ice, and scientists expect levels to keep rising. Scientists are still working to fully understand the long-term effects of TFA. The European Chemicals Agency classifies the chemical as harmful to aquatic life. Researchers have also detected TFA in human blood and urine. In addition, the German Federal Office for Chemicals recently proposed classifying TFA as potentially toxic to human reproduction.

06/09/2026 National Wildlife Federation Data Centers are Driving Up Your Energy Bill - Clean energy has become the cheapest form of energy, but wind and solar still only account for 17 percent of the country’s energy generation. The biggest barrier to deploying clean energy is usually transmission. Without enough transmission to deliver cheaper clean energy to where it’s needed, over 900 GW of solar and wind projects sit waiting in queue, and utilities often default to more expensive fossil fuel generation instead. We can double down on outdated systems that pollute our air and water and drive up prices, or we can invest in the resilient energy solutions that have proven to be the cheapest, build the grid needed to deliver them, and ensure the largest electricity users pay their fair share of the costs they trigger.

06/08/2026 National Parks Traveler Young Mountains, Old Rocks: A Geological Overview of the Teton Range - The Tetons continue to grow. The tectonic forces that built the range are still active, and stress continues to build even if the Teton Fault has not experienced major movement in recorded history. Evidence of ongoing stress appears east of the Teton Range, where the Snake River does not flow down the center of its riverbed. Instead, the river flows preferentially along the western side of its banks as the extensional stress builds and the eastern block of the fault (the block underlying Jackson Hole) tilts more westward.

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!
