Drones reveal 41,000-turtle nesting mega-site hidden in the Amazon

A team at the University of Florida used drones and smart modeling to accurately count over 41,000 endangered turtles nesting along the Amazon’s Guaporé River—revealing the world’s largest known turtle nesting site. Their innovative technique, combining aerial imagery with statistical correction for turtle movement, exposes major flaws in traditional counting methods and opens doors to more precise wildlife monitoring worldwide.

This gut hormone could explain 40% of IBS-D cases—and lead to a cure

A mysterious gut hormone may be behind many cases of chronic diarrhea, especially in people with undiagnosed bile acid malabsorption, a condition often mistaken for irritable bowel syndrome. Researchers from the University of Cambridge identified that the hormone INSL5 spikes when bile acid reaches the colon, triggering intense diarrhea. Their discovery not only sheds light on the biological cause of symptoms but opens the door to a diagnostic blood test and new treatment options, including a surprising existing drug that blocks this hormone’s effects.

Did humans learn to walk in trees?

In the quest to understand how and why early humans started walking on two legs, scientists are now looking to chimpanzees living in dry, open savannah-like environments for clues. A new study reveals that these chimpanzees, despite the open terrain, still frequently climb trees to gather fruit and other foods found high in the canopy. Their behavior suggests that bipedalism may not have evolved purely as a response to ground-based travel, but also for safe and efficient movement within trees.

Scientists just invented a safer non-stick coating—and it’s inspired by arrows

Scientists at the University of Toronto have developed a new non-stick material that rivals the performance of traditional PFAS-based coatings while using only minimal amounts of these controversial "forever chemicals." Through an inventive process called "nanoscale fletching," they modified silicone-based polymers to repel both water and oil effectively. This breakthrough could pave the way for safer cookware, fabrics, and other products without the environmental and health risks linked to long-chain PFAS.

7000 steps a day cuts death risk by 47%—and that might be all you need

Walking 7000 steps a day may be just as powerful as hitting the much-hyped 10,000-step goal when it comes to reducing the risk of early death and disease. A sweeping global review of 57 studies shows that 7000 steps per day slashes the risk of dying early by nearly half—and brings major benefits across heart health, dementia, depression, and more. The bonus? Even walking from 2000 to 4000 steps per day brings measurable improvements. For millions of people, this study redefines what it means to "move enough."

Is the air you breathe silently fueling dementia? A 29-million-person study says yes

Air pollution isn't just bad for your lungs—it may be eroding your brain. In a sweeping review covering nearly 30 million people, researchers found that common pollutants like PM2.5, nitrogen dioxide, and soot are all linked to a significantly higher risk of dementia. The most dangerous? PM2.5—tiny particles from traffic and industry that can lodge deep in your lungs and reach your brain.
