4/14/2026 SR+ An Ingenious Vortext Nanoplastics, Human Health & Investigative Science - Investigating here the relationship of microplastic and nanoplastic particles in the human body and the impact these Microplastics (MPs) and Nanoplastics (NPs) and their associated piggybacking chemical additives have as potent endocrine disruptors and other ways they impact human health. Before reading the full text of this report please listen to the Podcast of Dr. Aviva Romm, MD: “a Yale-trained board-certified family physician, midwife, and herbalist specializing in integrative medicine for women and children.

4/27/2026 The Conversation Global supply chains cause environmental harm, but they can help repair it too - When supply chains move beyond traditional markers of performance — efficiency, flexibility and responsiveness — to consider the benefits and harms of their activities, they can become environmentally just. Such supply chains distribute environmental benefits (such as clean air, water or access to land) more fairly while ensuring all stakeholders are included in decision-making.

4/27/2026 Science Daily Pesticide exposure linked to 150% higher cancer risk in major study - To better understand the link between pesticides and cancer, researchers created detailed models showing how agricultural chemicals spread across Peru. The analysis included 31 widely used pesticides. None of these are classified as known human carcinogens by the World Health Organization (WHO), yet their combined presence in the environment was carefully tracked. he team then compared these exposure maps with health data from more than 150,000 cancer patients recorded between 2007 and 2020. This comparison revealed a clear pattern. Regions with higher environmental pesticide exposure also had higher rates of certain cancers. In these areas, the likelihood of developing cancer was about 150% greater on average.

4/25/2026 Clean Technica Drought Could Be Making Antibiotic Resistance Worse - A recent study published in the journal Nature Microbiology found that when soil dries out, it can speed up the natural processes that create and spread antibiotic resistance. In normal, moist soil, bacteria live in a relatively stable environment. But when soil dries out, water gets squeezed into tiny, isolated pockets. Bacteria get crowded together, nutrients become scarce and competition turns brutal. In these conditions, bacteria produce more antibiotics to attack each other, and more resistance genes emerge to help them survive. It’s an arms race fueled by drought.

4/26/2026 BBC Surviving in a poisoned land: Chernobyl's wildlife is different, but not in the ways you might think - Four decades have now past since Chernobyl's reactor number four exploded on 26 April 1986, sending radioactive material far and wide. Tree Frogs inside the exclusion zone were, on average, darker than those outside the zone. Many pine trees, which are especially sensitive to radiation, died after exposure to fallout. Birch trees took over in some locations creating a completely different kind of forest. In areas once frequented by people, wolves, bears and bison now roam. Populations of deer, wild boar and elk have flourished. Species including the Eurasian lynx have also returned to the area after vanishing long before the accident. groups of dogs apparently descended from pets abandoned after the 1986 disaster, are also plentiful in this area.

4/25/2026 Planetizen Finland opens world's longest multimodal, car-free bridge - A new 0.74-mile bridge in Finland is likely the world's longest car-free bridge.  The Kruunuvuori Bridge, which opened last week, serves pedestrians, cyclists and, starting next year, trams. It connects Helsinki's eastern island suburbs with the city center.

4/27/2026 Smithsonian Magazine See the 1-in-50-Million Split-Color Lobster Caught Off the Coast of Massachusetts - The unusual-looking lobster is two-toned, with a line dividing its body into an orange side and a brown side. This can happen when two fertilized, unlaid lobster eggs touch—causing one to absorb the other

4/23/2026 Smithsonian Magazine A Rare ‘Cloud Jaguar’ Was Spotted in Honduran Mountains for the First Time in a Decade- The hefty felines can grow to eight feet long from nose to tail tip and weigh up to about 350 pounds. Jaguars have stocky, heavy bodies with short—but massive—limbs, as well as big heads and teeth that make for a powerful bite. They’re the third-largest cats in the world and the largest in the Americas.

4/22/2026 Yale Environment 360 Sustainable Wood Schemes Failing to Slow Deforestation - Schemes that certify wood or paper as sustainable are doing little to stem the loss of forests globally. The schemes are voluntary, run not by governments but by independent groups. Between 2013 and 2023, the world lost at least 50 million acres of forest each year, an area roughly the size of Nebraska, according to an analysis of satellite imagery. What is striking is that countries with more certified acres saw no less clearing of forest overall.

4/26/2026 The Conversation Soil monitoring: what the new EU‑wide ‘ground rules’ have in store for Europe - The European soil monitoring directive, adopted by the European Union at the end of 2025, aims to achieve healthy soils by 2050. It calls for soil microbial diversity analysis (bacteria and fungi) at six-year intervals based on environmental DNA or “eDNA”. Yet, while eDNA is a powerful tool for detecting biodiversity at scale, it is not enough on its own for interpreting observed changes and identifying their causes.

Meet the Kangaroos That Live in Trees - Filling an evolutionary niche akin to monkeys, they’re keystone species in the rainforests of New Guinea and Australia.

Manet Cut This Painting in Half 150 Years Ago. Now, the Two Sides Are Back Together for a Rare Reunion - In 1874, Manet began to paint a scene of the Brasserie Reichshoffen on a large canvas. Unlike his paintings of military scenes or upper-class life of the 1860s, the new piece captured the dramas of everyday life. But Manet became dissatisfied with the composition of the large work and opted to cut the canvas in two. Over the next few years, he refined each half into more concise, if slightly less ambitious, depictions of the same café: At the Café and Corner of a Café-Concert. While both paintings are well regarded, Manet’s contemporaries struggled to understand his decision to separate them. But Manet’s conviction that the two should be kept apart remained strong. When the two paintings of the same café were exhibited at the Triennial Salon in Antwerp in 1879, they were shown in separate rooms.

Deconstructing Buildings: The Quest for New Life for Old Wood - A growing number of cities have launched initiatives to reuse the wood waste from construction and demolition that now ends up in landfills. The challenge, proponents say, is to deploy new techniques for disassembling old buildings and markets for repurposing the salvaged wood. Using reclaimed wood in buildings stores carbon and helps reduce emissions by avoiding the need to cut new trees. Going forward, some architects say, buildings should be designed for disassembly — meaning every structure is built not only to last but also for easy dismantling and repurposing when its time is up.

Why the appendix is much more important than we once thought - The appendix has been shown to be an important component of immune function, especially in early life. In addition, the appendix itself contains a very diverse and varied microbiota distinct from other parts of the gastrointestinal tract, suggesting a specialized role. Removal of the appendix has been associated with a reduction in gut bacterial diversity which can lead to intestinal dysbiosis and potentially increase susceptibility to various diseases. Appendectomy has also been linked to an increase in fungal diversity in the gut; the appendix may play a role in the balance between bacterial and fungal populations, potentially acting as a store of commensal gut microbiota that repopulate the colon after exposure to pathogens or antibiotic treatment. The appendix may play a further role in protecting the gastrointestinal system from invading pathogens.

How Extreme Heat Impacts Children - Infants and young children sweat less and are unable to regulate their core body temperature as well as adults. Playgrounds are not always built with materials designed to withstand heat and prevent burns. Older children such as high school athletes face increased risk of heatstroke and other illnesses during practices and games. 

Weather makers: How microbes living in the clouds affect our lives - Trillions of bacteria, fungi, viruses and single-celled organisms travel the globe high in the atmosphere. Current aerobiologists deploy sophisticated air-samplers on drones and use DNA-sequencing technology to identify airborne life by its genes. The aerobiome, researchers now recognize, is an enormous habitat filled only with visitors. By one estimate about a trillion trillion bacterial cells rise each year from the land and sea into the sky. By another estimate, 50 million tons of fungal spores become airborne in that same time. Untold numbers of viruses, lichen, algae and other microscopic life forms also rise into the air. It's common for them to travel for days before landing, in which time they can soar for hundreds or thousands of miles. The aerobiome is a force to be reckoned with – one that exerts a powerful influence on the chemistry of the atmosphere. It even alters the weather. It turns out that biological molecules and cell walls are exceptionally good at triggering rain. More sobering… In a 2023 survey of clouds, bacteria carrying 29 different kinds of resistance genes were found.  A single airborne bacterium may carry as many as nine resistance genes, each providing a different defense against drugs. Every cubic meter of cloud could hold up to 10,000 resistance genes. A typical cloud floating overhead may hold more than a trillion of them.

The New Normal Is Already a Loss: How Shifting Baselines Skew Our View of Nature - Think back on the bird song you woke up to this morning. You might have pulled out a few recognizable threads, perhaps the robin, the crow, the sparrow. Now imagine what morning might have sounded like to your grandparents. Major scientific studies indicate that it was likely a cacophony of song by comparison—many kinds of birds and more of them. The difference, the shift in normal, is gradual over time and the loss, without memory or data, is hard to define. With each generation, our perception of the natural world changes, and with it, our understanding of what accounts for abundance and loss of biodiversity. A term bandied about is the “new normal.” In ecology, it’s called the shifting baseline syndrome. 

Fungi to the Rescue: How Mushrooms Are Helping Clean Up Toxic Lands - Mycoremediation, the use of fungi to break down pollutants and absorb heavy metals from contaminated soil. Certain species can transform petrochemicals, pesticides, and heavy metals into harmless compounds or concentrate them for safer removal. This nature-based method offers an affordable, less disruptive alternative to traditional “dig and dump” remediation approaches.

A History of Some National Park Roads – The only roads mentioned in the article I haven’t experienced is Generals Highway in California and Going-to-the-Sun Road in Montana!

The Famous, Feathered Dinosaur Archaeopteryx Could Fly, Suggests New Study of a ‘Beautifully Preserved’ Fossil - A fossil collector discovered the Chicago Archaeopteryx sometime before 1990 in limestone deposits near Solnhofen, Germany, where all known Archaeopteryx fossils originate. As the Field Museum’s preparators worked on the pigeon-sized Chicago Archaeopteryx, they realized that the fossil included more soft tissues and delicate skeletal details than any other known Archaeopteryx specimen. From previous fossils, they already knew the dinosaur had asymmetric feathers, which are vital to creating thrust in modern, flying birds. But the hard slab of limestone around this specimen had also preserved a key layer of feathers called tertials that had never been documented before in Archaeopteryx.

Are pumpkins a future superfood? – Maybe. The plants are high heat and drought tolerant….. and tolerate salinity. Nutritionally they have essential vitamins, minerals, and fats.

Do or dye: Synthetic colors in wastewater pose a threat to food chains worldwide - Dyes create several problems when they reach water systems, from stopping light reaching the microorganisms that are the bedrock of our food chains, preventing their reproduction and growth, to more direct consequences like the toxic effects on plants, soils, animals and humans. Remediation technologies for dye-containing wastewater, including chemical, biological, physical and emerging advanced membrane-based techniques.

Billions Of Snow Crabs Have Died in Alaska. Will Billions of People Be Next? – Starvation….but linked to marine heatwaves that affected snow crab metabolism.

Even treated wood prevents bacterial transmission by hand – Maybe we should be using wood more frequently for surfaces where keeping bacteria at bay is important (countertops, for example).

Staring at the Sun — close-up images from space rewrite solar science – Results from Parker Solar Probe and Solar Orbiter…and the ground-based Daniel K. Inouye Solar Telescope.

Higher levels of triglycerides linked to lower risk of dementia – A correlation…not necessarily a causal relationship.

Jupiter's volcanic moon Io looks stunning in new Juno probe photos – From an October 15th flyby.

The Rio Grande isn’t just a border – it’s a river in crisis – So many rivers are in trouble. The Rio Grande drought story is complicated by international treaty…and contentious relations at the border.

These Rare Daguerreotypes Are the Earliest Surviving Photos of Iran in the 1850s – It would be interesting to see what these same places look like today.

Why are bed bugs so difficult to deal with? – They are increasingly resistant to pesticides that previously were effective. Creating policies that require reporting and resident notification by landlords…and requiring the landlords to treat infestations within 30 days has been effective in New York. Infestations can be managed, but probably not eliminated.
