  • Researchers have known for decades that whales create elaborate songs, sometimes projecting their calls for miles underwater. A new study from the Woods Hole Oceanographic Institution (WHOI), however, has revealed a previously unknown element of whale songs that could aid this mode of communication, and may play a pivotal role in locating other whales in open ocean.

    • Research from the University of Sussex suggests that humans are unique among primates in being able to intentionally alter the frequencies of our voices to sound larger or smaller than we really are, a capacity that is likely to have evolved over many thousands of years. Body size is very important for many animals, including humans, in predicting social dominance, reproductive success and health. Because of this, communicating body size to others through vocal signals is important, and being able to alter ones voice to trick other members of the species is a useful evolutionary tool. Psychologists Dr Kasia Pisanski and Dr David Reby, in collaboration with researchers from the University of Havana, University of Wroc?aw, and McMaster University, have discovered that humans can intentionally lower or raise the frequencies of our voices to sound larger or smaller than we actually are.

    • NEWPORT, Ore. - A sophisticated new type of "tag" on whales that can record data every second for hours, days and weeks at a time provides a view of whale behavior, biology and travels never before possible, scientists from Oregon State University reported today in a new study. This "Advanced Dive Behavior," or ADB tag, has allowed researchers to expand their knowledge of whale ecology to areas deep beneath the sea, over thousands of miles of travel, and outline their interaction with the prey they depend upon for food. It has even turned whales into scientific colleagues to help understand ocean conditions and climate change.
