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?

Greenland Sled Dog DNA Reveals a Story of Human Migration and Ancestry of the Unique Breed - The ancestors of the Inuit arrived in Greenland earlier than previously thought—potentially even before the arrival of the Vikings.

A Bird’s Eye View: Drones Search for Grassland Birds in Colorado - Drones have been used to survey animals from afar for years; this project borrows from those learnings for the novel —and challenging—task of detecting small-bodied, ground-nesting birds (Bobolinks) amid thick, tall grass, without disturbing the species of interest.

Hungary's oldest library is fighting to save 100,000 books from a beetle infestation - Tens of thousands of centuries-old books are being pulled from the shelves of a medieval abbey in Hungary to save them from a beetle infestation that could wipe out centuries of history. I wondered how many of the books have been scanned.

'Wobbly-tooth puberty': How children's brains change at six-years-old – A stage in which a child is constructing their identity, and they're trying to figure out who they are in relation to other people. The transformation includes a greater capacity to reflect on their feelings and modify them when needed, along with an "advanced theory of mind" that allows them to think more sophisticatedly about others' behaviors and respond appropriately. They also begin master the basics of rational enquiry and logical deduction, so that they can take more responsibility for their actions

How a hidden brain circuit fuels fibromyalgia, migraines, and PTSD - Scientists at the Salk Institute have discovered a hidden brain circuit that gives pain its emotional punch—essentially transforming ordinary discomfort into lasting misery. This breakthrough sheds light on why some people suffer more intensely than others from conditions like fibromyalgia, migraines, and PTSD. By identifying the exact group of neurons that link physical pain to emotional suffering, the researchers may have found a new target for treating chronic pain—without relying on addictive medications.

Greenland’s Bejeweled Ice Sheet - In spring 2025, jewel-toned points of blue began to appear on the white surface of the Greenland Ice Sheet. As summer arrived, they grew larger and more numerous, taking on unique shapes and occasionally forming connections. The colorful seasonal phenomenon is due to meltwater from snow and ice, which pools atop the ice sheet in places each melt season. An image from the Operational Land Imager-2 on NASA’s Landsat9.

Easter Island Was Far Less Isolated Than Previously Believed, Study Reveals - Earlier genetic studies in the 2010s laid the ground for the most recent investigation, showing that Easter Island was reached at least two times by the 14th century. Further influence arrived from pre-European South Americans, an interaction evidenced by the presence of sweet potatoes and the Birdman concept. This post is about the idea that after language, plants, animals, and material culture arrived on Easter Island from the west, monumental ritual architecture began traveling in the opposite direction.

In a First, Solar Was Europe’s Biggest Source of Power Last Month - Solar was the largest source of electricity in the EU in June, supplying a record 22 percent of the bloc’s power. Solar amounted to more than 40 percent of generation in the Netherlands and 35 percent in Greece. Analysts say that the June surge in solar power helped Europe weather a brutal heat wave, which saw temperatures soar upwards of 110 degrees F (43 degrees C). Last month was the warmest June on record in Europe, and scientists say that climate change played a key role in the heat wave, pushing temperatures to dangerous extremes.

Inequality has risen from 1970 to Trump − that has 3 hidden costs that undermine democracy – A thought provoking post. The author described 3 ways that the increase in inequality undermines democracy: 1. Fraying social bonds and livelihoods, 2. Increasing corruption in politics, 3. Undermining belief in the common good.

Honeybees remove 80% of pollen—leaving native bees with nothing - Our modern agricultural industry is so reliant on honeybees that humans have introduced them worldwide, and in many cases, they have escaped human management and risen to prominence in natural ecosystems as non-native, feral populations. And, like any other non-native organism, feral honeybees may perturb native ecosystems when they become sufficiently abundant.
