Feed These Bacteria a Splash of Glycerol, and 95% of the Uranium Leaves the Water

Microbes in a flooded German uranium mine turned 95 percent of the dissolved metal into an iron compound that held together when oxygen returned, the exact failure that has always defeated standard cleanup.

Brain & Aging

They Measured the Forever Chemicals in the Umbilical Cord Itself. The Babies With the Most Scored Lower at Two.

Scientists skipped the usual stand-in and measured the forever chemicals in the umbilical cord blood itself. By age two, the babies carrying more of them scored lower on communication and motor development, and the companies that made these chemicals knew the risk for decades.

Chemists Cracked Unsorted Plastic Into Hydrogen With Lye, and Trapped Three-Quarters of the Carbon Instead of Torching It

Most plastic never gets recycled. It gets burned or buried, and polyethylene keeps turning up in human brain tissue. A UCLA and Ewha team cracked mixed, unsorted trash into more than 90 percent pure hydrogen at low heat and trapped 75 percent of the carbon instead of letting it escape.

The Lungs May Be Where Rheumatoid Arthritis Actually Starts

Across Italy, South Korea, and California, higher fine-particle pollution tracks more RA flares and more new cases, and the biology keeps pointing at the airway, not the knee.

Lead Strips Dopamine From the Exact Brain Circuit ADHD Drugs Are Built to Rescue

Childhood lead keeps landing on the same target: the striatal dopamine circuit that ADHD drugs are built to rescue. A Philadelphia cohort just tied it to real diagnoses, not test scores.

A Road Made From Recycled Fishing Nets Shed Less Microplastic Than the Tires Rolling Over It

Hawaii scientists laid ocean-net plastic into a real Oahu street, then measured what came off. The recycled plastic barely registered. Tire wear, the source almost nobody regulates, swamped it by orders of magnitude.

We Fixed the Ozone Hole. The Replacement Is Now in Your Blood.

A new Lancaster modeling study finds CFC replacement refrigerants and anesthetic gases have rained 335,500 tonnes of the forever chemical TFA across the planet since 2000, and it is now the dominant PFAS in American blood.

A 16-Foot Fire Tornado Burned an Oil Slick With 40% Less Soot. Cleanup Crews Have Been Breathing the Same Old Smoke Since the Exxon Valdez.

A federally funded field trial used a controlled fire whirl to burn up to 95% of a crude oil pool while cutting soot by 40%, raising the question of why the standard in-situ burn, with its measured worker-lung cost, has gone unchallenged for thirty-five years.

The Crunchy Mom and the MAHA Mom Were Fighting the Same War. The Pesticide Lobby Won Anyway.

For one strange year, the EWG hiking-boots crowd and the MAHA red-hat moms were fighting the same pesticide war. Then Trump invoked the Defense Production Act on behalf of Bayer, the final MAHA report quietly stopped mentioning glyphosate, and a coalition that was actually winning got stomped by a C
