Brown University-led Team Discovers How Bats Avoid Collisions
March 29, 2010
How do bats avoid colliding with objects while flying? A Brown University-led team, using tiny microphones on bats' heads, reports that bats tweak the frequencies of the sounds they emit to detect and maneuver around obstacles. The scientists also found that bats make mental templates of each sound (or broadcast) and the echo it creates, to differentiate one broadcast/echo set from another. Results appear in Proceedings of the National Academy of Sciences.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2012, its budget was $7.0 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 50,000 competitive requests for funding, and makes about 11,500 new funding awards. NSF also awards about $593 million in professional and service contracts yearly.
