Scientists at the University of East Anglia discovered that humans can learn to use mouth clicks like bats do, judging distances after just a short training session. This breakthrough could transform how we help visually impaired people navigate their world.
Molly Burke reached out and touched a tree in a park without a cane or guide dog, stunning her boyfriend who was filming. She was using passive echolocation, a real skill she learned as a child to navigate by detecting "sound shadows."
Scientists discovered how bats fly through cluttered environments without crashing by detecting motion changes in sound waves. The breakthrough could help make drones and self-driving cars safer in complex spaces.

Scientists used a robot to crack the code of how tiny bats detect motionless insects hiding on leaves using sound waves. The discovery could lead to pest-fighting farm robots that protect crops without chemicals.
Scientists created tiny drones that "see" in the dark using bat echolocation, opening new possibilities for rescue missions in fires and collapsed buildings. The breakthrough solves a problem that has stumped robotics engineers for years.
Those dark shapes zigzagging across your yard at dusk aren't random visitors. Scientists say returning bats mean your garden is healthier than you think.
Norway is introducing electric sightseeing vessels that will dramatically reduce noise pollution and emissions in its famous fjords. The ships promise a more peaceful experience for passengers while protecting marine wildlife.
Scientists discovered hedgehogs can hear ultrasound frequencies up to 85kHz, opening the door to road-safe devices that could prevent thousands of deaths. Cars with built-in ultrasound repellers could soon keep these beloved mammals out of harm's way.
Scientists discovered that a tiny change in mouse brains enabled complex songs and polite conversation, the same mutation believed to have sparked human language. The finding suggests our most unique ability required less evolutionary rewiring than we thought.
A UK city just secured lottery funding to help residents reconnect with nature through bat walks, birdsong events, and twilight celebrations. The project tackles a surprising gap: while most people know nature boosts happiness, only half feel truly connected to it.
Scientists finally captured video proof of sperm whales headbutting each other, confirming legends told by 19th-century sailors. The surprising footage reveals younger whales, not adults, engage in this powerful behavior.
Global shipping regulators just approved new guidance to reduce underwater noise threatening narwhals and other Arctic whales. Simple fixes like slower speeds and cleaner hulls could cut noise pollution nearly in half while saving fuel.
Scientists discovered European hedgehogs can hear ultrasonic frequencies up to 85,000 hertz, opening the door to car-mounted sound devices that could save them from roadkill extinction. One-third of hedgehog deaths come from vehicle collisions, pushing these adorable creatures toward threatened status.
Researchers discovered that 55 pilot whales beached themselves on Scotland's Isle of Lewis because they were protecting a pod member in distress. The tragedy reveals the remarkable loyalty of one of the ocean's most social species.
An AI system listens for endangered orca calls 24/7 and alerts Seattle ships to slow down or pause construction, giving the world's last 76 southern resident orcas a fighting chance. The technology has already detected the whales on 19 days this year.
Blue whales sing at frequencies so low that killer whales can't hear them beyond a kilometer, effectively making the ocean's loudest animal acoustically invisible to its only predator. This discovery reveals how nature's largest creatures use sound as a survival tool.
Engineers created underwater mapping technology that works even in cloudy, sediment-filled water by combining sonar and cameras. The breakthrough could revolutionize underwater exploration, construction, and safety operations.
Researchers have developed a breakthrough framework that helps us finally understand what animals actually experience, transforming how we care for billions of creatures. The "teleonome" system could end decades of guessing about animal welfare.
