Underwater noise pollution threat to marine life

A breakthrough study by a specialist European research team, including scientists at the University of St Andrews, shows man-made underwater noise pollution is picked up by whales in a similar way they sense natural predators, ...

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 ...
