Human hair used to make flexible displays for smart devices

Researchers from the Queensland University of Technology and Griffith University have developed a method for turning small hair strands into carbon nanodots, which are tiny, uniform dots that are one-millionth of a millimeter. ...

Using AI to map marine environments

Sonar is commonly used to map the ocean floor, and seabed composition (e.g. mud, clay or rock) affects the way the sound is reflected back. Salinity, depth and water temperature also affect how sound waves are propagated ...

Artificial materials reconstruct porpoise's echolocation

Over millions of years, porpoises have developed powerful biosonar with high accuracy and intelligence to detect and track prey in noisy underwater environments. The sound source in a porpoise is about one half of the wavelength ...

More dolphins die in Aegean Sea; group suspects navy drills

The Aegean Sea has seen a "very unusual" spike in dolphin deaths over the past few weeks, a Greek marine conservation group said Monday, adding that the rise could be linked to massive Turkish naval exercises in the area.

Underwater ice terrace observed at the front of Grey Glacier

By using underwater sonar, researchers have found that a glacier jutting into a freshwater lake in southern Chile looks different underwater compared to ocean-bound glaciers in Greenland. Their findings, published in the ...

Sonar disturbs blue whales feeding

No one really knows why pods of whales spontaneously drive themselves aground. Military sonar may be one culprit, and the need to train and test submarine tracking technology in open water could put the US Navy in conflict ...
