08/15/2026 BBC  Future The controversial story of the North American raccoons wreaking havoc in Germany - One morning in April 1934, the records show, the animals were released from two crates to the south side of Lake Edersee near Vöhl, around 50km (30 miles) to the south-west of Kassel. This population grew and grew. Today, Kassel has been called the "raccoon capital of Europe", with an estimated urban population of around 30,000 of the animals.    

08/21/2026 Smithsonian Magazine An ‘Extremely Rare’ Half-Male, Half-Female Bird Temporarily Took Up Residence Outside of Chicago - An eye-catching bobolink with both male and female characteristics temporarily took up residence at a nature preserve just west of Chicago. The bobolink is what’s known as a “bilateral gynandromorph.” Because of a genetic anomaly, the right side of its body is male while the left side is female, with a straight vertical line dividing the two halves. It’s believed to be the first documented gynandromorphic bobolink. The bird behaved like a male, eventually wooing a mate and raising fledglings.

08/21/2026 Science Daily Archaeologists discover mysterious 400-year-old Indigenous pot in Florida - The pot was compact enough to fit in a palm, with a simple rim, a smooth dull gray surface, and no decoration. Its original purpose is unknown, as is the number of people who may have used it. What archaeologists do know is that the vessel survived for centuries underground

08/21/2026 Artnet Why Louis Comfort Tiffany Still Dazzles Collectors - Louis Comfort Tiffany‘s lamps are coveted and his stained glass is celebrated, but the artist behind the famous brand has remained stubbornly in the shadows. Two new exhibitions aim to throw the spotlight on his full talents.

08/21/2026 Clean Technica Sunrun Shifts Away from Affiliates to Direct Sales - Sunrun has been the #1 rooftop solar power installed in the United States for several years now.Sunrun installed 19,793 subscriber systems in the second quarter of this year, which is an amazingly high number. However, the bad news is that this was down 31% from Q2 2025. Yikes. On the plus side, the company had a higher percentage of its solar power systems get energy storage add-ons than ever before — a whopping 74%. That’s up from 70% in Q2 2025. Sunrun has surpassed 266,000 total storage systems installed, accounting for 4.6 GWh of capacity. That includes the 332 MWh installed last quarter.

08/19/2026 NASA Elephant Butte Reservoir Runs Low - Elephant Butte Reservoir, the largest reservoir in New Mexico, is at its lowest level since 1971. My husband and I took a birding field trip in a boat on the reservoir in November 2016; they told us it was low then…and I wonder what has happened to the birds (pelicans, grebes, coots, and cormorants) that won’t find much water when they return to the area this fall.

08/19/2026 The Prairie Ecologist The Notorious (and other) Visitors to Our New Prairie Garden – Lots to photograph in a native plant garden!

08/19/2026 Planetizen To guarantee residents fresh water, Tijuana looks to the sea - The project is expected to produce 2,200 liters of fresh water per second — about 190,000 cubic meters a day — and increase available freshwater in the region by 45%. Construction is set to begin on Aug. 18, one day after signing the contract but nearly three weeks after the project's intended start date of Aug. 1.  It is expected to be complete in 2029.

08/18/2026 Yale Environment 360 Collapse of Atlantic Currents Could Drive a Surge in Warming - A vast system of Atlantic currents appears to be weakening, and scientists say its collapse could lead to dramatic cooling in northern Europe. A new study suggests an additional risk: a surge in warming across the rest of the globe.

08/21/2026 BBC Future India is turning to ancient water systems as modern ones run dry - In recent years, India is increasingly looking to revive ancient water structures as a way to help address the country's looming water crisis. Baoris, or ancient stepwells – large scale tiers of carved stone with steps that descend into the water table, allowing access to groundwater – are the most striking. Thousands of disused subterranean stepwells, built from the 7th to the mid-19th Centuries, famously dot India's landscape. From New Delhi to Jodphur, dozens have been restored in recent years. Open traditional structures like stepwells do not escape evaporation completely, but by helping to move water beyond reach of the Sun into aquifers they allow it to stay both cool and reachable by any well or handpump nearby.

2/20/2026 BBC How ultra-processed foods affect our gut microbiome - The additives added to processed food to keep it fresher for longer might be having an unexpected effect on the health of the microbes in our guts. Research carried out on both animals and humans appears to pinpoint a direct link between emulsifiers and ill health. One French study of more than 100,000 adults in 2024 found those who were more exposed to emulsifiers had a greater risk of type 2 diabetes. Another study of more than 90,000 adults found a potential link between emulsifiers and breast and prostate cancers.

2/20/2026 Smithsonian Magazine Researchers Retrieve the Deepest-Ever Rock Core from Beneath Antarctica’s Ice. It Holds Clues About the Earth’s Past—and Future - The 748-foot-long sediment core contains a record of roughly the past 23 million years, including periods when the planet’s surface temperature was hotter than it is today.

2/20/2026 National Parks Traveler Tidal Basin Gets Hundreds of New Cherry Trees - Paid for by a generous donation from the nation of Japan, the trees represent the most recent chapter in this remarkable cultural exchange dating back to Japan's original gift of cherry trees in 1912.

2/19/2026 Science Daily New sodium ion battery stores twice the energy and desalinates seawater - Being able to use sodium vanadate hydrate in salt water is a really exciting discovery, as it shows sodium-ion batteries could do more than just store energy -- they could also help remove salt from water. In the long term, that means we might be able to design systems that use seawater as a completely safe, free and abundant electrolyte, while also producing fresh water as part of the process.

2/18/2026 The Guardian Hazardous substances found in all headphones tested by ToxFREE project - Bisphenol A (BPA) appeared in 98% of samples, and its substitute, bisphenol S (BPS), was found in more than three-quarters. Synthetic chemicals used to stiffen plastic, BPA and BPS mimic the action of estrogen inside organisms, causing a range of adverse effects including the feminization of males, early onset puberty in girls, and cancer. Previous studies have shown that bisphenols can migrate from synthetic materials into sweat, and that they can be absorbed through the skin. Given the prolonged skin contact associated with headphone use, dermal exposure represents a relevant pathway, and it is reasonable to assume that similar migration of BPA and its substitutes may occur from headphone components directly to the user’s skin.

2/17/2026 The Conversation Air pollution may directly contribute to Alzheimer’s disease – U.S. researchers tracked nearly 28 million older adults over six years nationwide. They found that those exposed to higher levels of fine particulate air pollution were more likely to develop Alzheimer’s. The US study used Medicare insurance claims to confirm Alzheimer’s diagnoses and area data by postcode for fine particle pollution levels. It also looked at other factors that could explain the link, such as the proportion of smokers or overweight people living in more or less polluted areas.

1/15/2026 Science Daily Scientists question the safety of BPA-free packaging - BPA-free is an incredibly misleading label. It usually means one bisphenol has been swapped for another, and there are more than 200 of them. Some may be just as harmful, or even worse. We need to test these compounds before they're widely adopted, not after.

2/11/2026 Archaeology Magazine What Caused Ancient People to Abandon a Fruitful Bison Hunting Site? - For around 700 years, Native people of the American Great Plains hunted bison at a site in central Montana that archaeologists call Bergstrom. Then, around 1,100 years ago, humans abandoned the site even though bison remained abundant in the area. Researchers discovered that drought caused the water supply to process the animals at the site dried up…forcing the hunters to move away.

2/23/2026 Planetizen California Seals 21 Urban Oil Wells in South LA After Decades of Activism – There are too many stories like this – why do we ever trust the oil companies to not walk way and leave a toxic mess? I’m glad the state is stepping in…but the companies that made money from the site over the years need to be held financially accountable.

2/23/2026 Science Daily Babies exposed to far more “forever chemicals” before birth than scientists knew - By using advanced chemical screening on umbilical cord blood, scientists detected 42 different PFAS compounds, including many that standard tests do not routinely check for. These long lasting chemicals are found in common products like nonstick cookware, food packaging, and stain resistant fabrics, and they can build up in the body over time. The study helps show that prenatal PFAS exposure is more complex and widespread than earlier studies suggested
