Humpback whale population on the rise after near miss with extinction - A new study finds that the western South Atlantic humpback population has grown to 25,000 whales. Researchers believe this new estimate is now close to pre-whaling numbers.
Stranded whales detected from space - A new technique for analysing satellite images may help scientists detect and count stranded whales from space. Researchers tested a new detection method using Very High Resolution (VHR) satellite images of the biggest mass stranding of baleen whales yet recorded. It is hoped that in the future the technique will lead to real-time information as stranding events happen.
Hush, little baby: Mother right whales 'whisper' to calves - A recent study explores whether right whale mother-calf pairs change their vocalizations to keep predators from detecting them.
Scientists uncover genetic similarities among species that use sound to navigate - Insect-eating bats navigate effortlessly in the dark and dolphins and killer whales gobble up prey in murky waters thanks in part to specific changes in a set of 18 genes involved in the development of the cochlear ganglion -- a group of nerves that transmit sound from the ear to the brain, according to a new study.
Researchers use drones to weigh whales - Researchers have devised a way to accurately estimate the weight of free-living whales using only aerial images taken by drones.
