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.)

12/4/2025 American College of Emergency Physicians Opinion: Physicians Must Reduce Plastic Waste - Waste audits in the emergency departments (EDs) of Kent Hospital in Warwick, Rhode Island, and Mass General Hospital in Boston found that four pounds of waste is generated per patient, per encounter, and about 60 percent of the waste is plastic…. If we consider our plastic footprint with everything we are doing, we can adjust our habits to give our patients and our world healthier care.

11/19/2025 Consumer Reports Consumer Reports announces winners of its Microplastics Detection Challenge - Contest challenged participants to develop simple and inexpensive at-home tests to enable people to detect microplastics in their food. 

12/12/2025 Yale Environment 360 Dozens of Countries See Their Economy Grow as Emissions Fall - Historically, more industry meant burning more fossil fuels. 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.

12/7/2025 Cool Green Science Family, Survival and Change: The Secret Life of the Red-cockaded Woodpecker - In the heart of the longleaf pine forests of the southern United States, a quiet drama plays out each spring. 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. 

11/30/2025 The Conversation 56 million years ago, the Earth suddenly heated up – and many plants stopped working properly - Plants can help regulate the climate through a process known as carbon sequestration. However, abrupt global warming may temporarily impact this regulating function. What happened on Earth 56 million years ago highlights the need to understand biological systems’ capacity to keep pace with rapid climate changes and maintain efficient carbon sequestration.

12/8/2025 The Planetary Society The year in pictures 2025 - This collection of images, going as far back as late November 2024, captures some of the highlights of humanity’s exploration of space over the past year.

11/6/2025 The Scientist What Happens When a Fly Lands on Your Food? - How many microbes does a single fly typically carry? How many microbes does it take to get people sick?

Fall 2025 International Student Enrollment Outlook and Economic Impact – The drop in new international student enrollment in the United States this fall could result in a 15 percent drop in overall enrollment. This drop would result in nearly $7 billion in lost revenue and more than 60,000 fewer jobs.

Woodpeckers thrive where missiles fly. How a bombing range became a wildlife refuge - A U.S. Air Force bombing range in Florida has become a sanctuary for endangered species like the red-cockaded woodpecker!

Used EV Batteries Get New Life Supporting the Texas Power Grid - In Texas, retired EV batteries are being repurposed to shore up the state’s unstable electric grid. Batteries have made significant capacity contributions within Texas’ electric grid in recent years and have been credited with helping prevent summer blackouts by bolstering grid reliability.

World Cannot Recycle Its Way Out of Plastics Crisis - The world churns out more than 200 times as much plastic today as it did in 1950, and production is only rising. Microscopic bits of plastic waste have been found nearly everywhere. Many of the more than 16,000 chemicals used in plastics — flame retardants, fillers, dyes — can harm human health, and fetuses, infants, and young children are particularly vulnerable. Without efforts to stem the use of plastic, production is on track to nearly triple by 2060.

Gorgeous, Hidden Animal Tattoos Discovered on a More Than 2,000-Year-Old ‘Ice Mummy’ by Using Digital Imaging - Tigers, stags and a leopard twist around each other, the animals’ stylized and intricate details spread in ink across a woman’s forearm. On her hand is the delicate outline of a bird with a fluffy tail. It sounds like something you might see from a tattoo artist today, but these designs appear to be preserved on a more than 2,000-year-old “ice mummy” from Siberia’s Pazyryk culture.

How do the microplastics in our bodies affect our health? - The use of plastics in society first came into being on a large scale in about the 1920s, and we see a big increase from the 1960s onwards. In a study published in 2024, scientists found that consumption of the particles has increased sixfold since 1990, particularly in various global hotspots including the US, China, parts of the Middle East, North Africa and Scandinavia. In February 2025, scientists identified microplastics in the brains of human cadavers. Most notably, those who had been diagnosed with dementia prior to their death had up to 10 times as much plastic in their brains compared to those without the condition. Because humans are consuming so many different types of plastic, it's both unlikely and impractical, without vast sources of funding, for researchers to be able to identify a direct link between ingesting microplastics and one particular disease….but there is mounting evidence that they are impacting health.

This diet helped people lose twice as much weight, without eating less - People eating minimally processed foods lost twice as much weight as those on ultra-processed diets, even though both diets were nutritionally balanced and participants could eat freely!

A Promised U.S. Drilling Boom Has Yet to Materialize - The price of oil, the world’s most-traded commodity, is more responsive to global demand and supply dynamics than to domestic policy and politics. The economics of solar and wind are increasingly too attractive to ignore. They are now almost always the least expensive — and the fastest — option for new electricity generation.

Your sleep schedule could be making you sick, says massive new study - A global study of over 88,000 adults reveals that poor sleep habits—like going to bed inconsistently or having disrupted circadian rhythms—are tied to dramatically higher risks for dozens of diseases, including liver cirrhosis and gangrene.

Climate Change Responsible for Recent Decline of Eastern Monarch Butterflies – I know that the milkweed in my Maryland yard is not as healthy looking and I don’t see as many butterflies as I did in the 1990s…it’s a sad trend.

Top 25 birds of the week: July 2021 and Perching – A special treat – two collections of bird photographs in this gleanings post!

The parenting penalties faced by scientist mothers – There are no single or quick ‘fixes’ – moving forward requires thoughtful approaches. The status quo is not acceptable or sustainable!

True Grit: Adventures in Red-Cockaded Woodpecker Research – My husband and I saw red-cockaded woodpeckers in Florida during a birding festival field trip…so I tend to look at articles that appear in my news feed about them.

Florida Breaks Annual Manatee Death Record In First 6 Months Of 2021 – Florida seems to be a less appealing place to visit these days. Manatees were an animal my husband and I always wanted to see there and now they are starving to death because the seagrass (their food) is dead or dying in polluted waters. Other animals are probably impacted as well.

Chaco Culture National Historical Park: Hard To Reach, Filled With The Unexpected – I’ve only been to Chaco Canyon once….in the spring when it wasn’t overly hot. There were not many people on the windy, cool day we were there. The sounds of the place increased the sense of history in the ruins.

Air pollution during pregnancy may affect growth of newborn babies – There are so many aspects of the human impact on our environment that overwhelm what our bodies can handle…we should probably assume that there will be health impacts – particularly noticeable in the very young and the very old.

Burrowing Owls Face an Uncertain Future – They need holes from small colonial mammals….areas that are not plowed.

U.S. Power Sector Sees Biggest One-Year Drop in Emissions in More Than Two Decades – Picking up the pace as more renewables come online.

‘Inflammation clock’ can reveal body’s biological age – Maybe this turns out to be a good diagnostic to prompt interventions to extend healthy lifespan (via treatments on specific types of inflammation).

Three Kinds of Woodpeckers

/

The third day of the Space Coast Birding and Wildlife Festival got off to an early start – on a bus at 5 AM heading to the rural area in central Florida for a day of birding (about 50 miles south of Orland). We arrived at our first stop in Three Lakes Wildlife Management Area just before sunrise and hiked into the longleaf pine forest.

Our guides took us off the trail and through the palmettos and other vegetation growing between the pines – and pointed out the woodpecker holes in the pines. We stood and watched the holes.

Sure enough just as the day brightened a little – a red-cockaded woodpecker appeared in one of the longleaf pines (the only tree they use for nesting).

The bird flew out to neighboring pines in search of breakfast. I never saw a red-cockade…but read that they are difficult to see in the field.

The long leaf pines are not as numerous as they once were. They don’t grow in dense stands so are not as commercially viable as other pines in the south. But they are a boon to wildlife and are resistant to wildfire.

As we walked back toward the bus we saw a brown-headed nuthatch – another bird of the longleaf pine forest (which I didn’t manage to get a picture of) and our second woodpecker of the day. I saw the typical holes first – the work of a yellow-bellied sapsucker.

Soon we saw the birds themselves. They too were after breakfast.

Further down the country road we stopped at a stand of trees with some snags…and saw red-headed woodpeckers almost immediately. A lot of woodpeckers have red on their heads – but the name is reserved for this one. The head is red all over!

What a thrill to see three kinds of woodpeckers in one day of birding!
