UC Berkeley psychologist Fred Theunissen's work on songbirds could help improve hearing aids to allow people to home in on specific sounds in noisy environments, a particular problem for the hard of hearing. He and his graduate students study zebra finches, which are especially adept at listening in crowded, noisy environments, and developed an algorithm for reducing distortion in hearing aids.
Amid the amazing biodiversity of the Indonesian island of Sulawesi lives a 5-gram frog that gives direct birth to tadpoles, without ever laying eggs. This unique reproductive strategy, found in a group of fanged frogs endemic to the island, is described for the first time by UC Berkeley herpetologist Jim McGuire and colleagues from Indonesia and Canada.
