A plant-inspired filter is pulling microplastics out of Atlantic City's wastewater

A startup founded by two Princeton graduates has installed what it calls the world's first large-scale system for filtering microplastics out of wastewater, at a treatment plant serving Atlantic City, New Jersey. The design copies water-shedding plants: water slides off while tiny plastic particles stick, so they can be collected and sent for recycling. A prototype removed 98% of microplastics in lab tests, and a two-year pilot will see if it does as well in the real world, even though no federal rule requires it yet.

Divers rescue a young kangaroo found swimming far out to sea

A dive boat crew in South Australia's Boston Bay did a double take when their skipper spotted a juvenile kangaroo paddling about 3 kilometers from shore. The exhausted roo let diver Jake Murray scoop it aboard, where it eventually dozed off in his arms. Hours later it hopped away from the beach under its own power, and nobody is quite sure how it ended up so far out.

An anonymous diner had even added extra premium beef to their order before settling the whole tab and slipping out. A longtime volunteer said it was a day she would never forget.

Namibia's Lion Rangers mix smartphones and tracking skills to keep desert lions and farmers safe

In north-west Namibia, a community program called Lion Rangers uses GPS collars, camera traps and phones alongside traditional tracking to warn farmers when lions are near their livestock. It runs across 11 local conservancies and has grown to more than 40 rangers and patrol leaders. Conservation work helped the region's desert lions rebound from about 20 adults in 1997 to around 180, and the rangers help keep that recovery going by heading off conflict with people.

A student exchange program helps American teens see their own country through new eyes

The American Exchange Project sends recent high school graduates on weeklong stays in U.S. communities very different from their own, from Utah to Texas to the Bronx. The students then host their new friends in their own hometowns, so the exchange runs both ways. Participants say the deep conversations surfaced real differences but also a surprising amount of common ground.

Europe's fire salamanders have a hidden green glow

Researchers found that fire salamanders, the familiar black-and-yellow amphibians, fluoresce green and cyan under ultraviolet light, especially on their yellow undersides. The glow comes mainly from skin glands and their toxic secretions, which keep glowing for more than a day after release. It's a reminder that even well-studied animals still have surprises when seen with new tools.

Mayo Clinic studies point to new ways to tackle aging 'zombie' cells

Seven Mayo Clinic studies dig into senescent cells, which stop dividing but linger and pump out inflammation linked to age-related disease. The team built better ways to identify the different kinds of these cells and tested strategies to target them, including a natural compound found in tomatoes. In aging mice, the treatments reduced inflammation and improved physical and brain health.

Early humans reached the Jordan Valley at least 1.9 million years ago

Using three independent dating methods, researchers found the 'Ubeidiya site in the Jordan Valley is at least 1.9 million years old, far older than earlier estimates of 1.2 to 1.6 million years. That makes it, along with Dmanisi in Georgia, one of the oldest known places early humans lived outside Africa. It suggests our ancestors spread into the region earlier than scientists thought.

Meet 'D-rex,' a record-breaking giant fungus from China's forests

Scientists in Yunnan, China, discovered a new fungus, Dianjunus rex, whose upright fruiting structures grow up to 50 centimeters tall and weigh as much as 2.2 kilograms. That makes them the largest known among a huge group of fungi called ascomycetes. It belongs to an entirely new fungal family whose lineage seems to date back to just after the dinosaurs died out.
