Scientists Confirm What Every Beachgoer Secretly Fears About Seabirds

gizmodo.com Gayoung Lee 2025-11-18 00:00:50

As a seabird researcher, Leo Uesaka spends most of his time reviewing hours of bird footage. That can get quite tedious and demanding at times, but every second is worth paying attention to—after all, that’s how you notice things like the penchant for seabirds to poop only while airborne. In a first-of-its-kind study published today in Current Biology, Uesaka and his team report that streaked shearwaters—large, unassuming seabirds common in East Asian waters—engage in a very specific type of ba

What Do Kids Actually Think About AI?

wired.com Charley Locke 2025-11-19 00:00:00

Ask an adult what they think about kids and AI, and expect to hear a strong opinion. Parents, politicians, experts—everyone has a take on whether young people should use AI, how to moderate their exposure, and how it’s changing the ways they think and communicate. Many of these opinions revolve around education. Adults fret that kids will turn ChatGPT into a research bot, paper writer, or math problem solver.

Toothpaste Made From Hair Works Better Than Fluoride, Scientists Say

gizmodo.com Natalia Mesa 2025-11-18 05:00:15

Looking for an effective, sustainable toothpaste? It might be on top of your head. Scientists have discovered that keratin, a protein found in hair, skin, and wool, can repair tooth enamel and stop tooth decay. It might also protect teeth even better than conventional fluoride-based toothpastes, stopping tooth decay in its tracks, according to a new study. When keratin comes into contact with saliva, it forms a protective coating that mimics natural enamel, the study shows. Not only can it shi

How We’ll Know for Sure If Microplastics Are Destroying Our Health

Doctors Were Worse at Spotting Cancer After Leaning on AI, Study Finds

Artificial intelligence tools have been shown to help doctors detect pre-cancerous growths in the colon—but don’t even think about taking those tools away once you’ve introduced them.

Some health enthusiasts swear by smartwatches as a way to monitor stress levels, but a recent study calls into question that common usage. The study, published in the Journal of Psychopathology and Clinical Science, claims that such watches display a very limited ability to actually communicate what a person’s psychological state is.

Weirdly Hot Rocks in New England Traced to 80-Million-Year-Old Greenland Rift
