Rise in mass die-offs seen among birds, fish and marine invertebrates

Mon, 01/12/2015 - 13:00
An analysis of 727 studies reveals that there have been more instances of rapid, catastrophic animal die-offs over the past 75 years. These mass kills appear to have hit birds, fish and marine invertebrates harder than other species.

How songbirds may help build a better hearing aid

Tue, 01/06/2015 - 11:51
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.

Unique Sulawesi frog gives birth to tadpoles
