When people think of the fastest animals, most consider running cheetahs, flitting hummingbirds, or jumping kangaroos. But there's a level above what we think of as “fast”: Ultrafast organisms conserve energy and move in nano- or even micro-seconds.
Sheila Patek, PhD, an associate professor in the biology department at Duke University, discusses her research on ultrafast creatures, including the powerful punch of the mantis shrimp and the force behind trap-jaw ants. By using high-speed digital cameras, Dr. Patek and her colleagues are among the first in their field to successfully analyze in slow motion the biology and intention behind these movements.
Dr. Patek goes into more depth about the biology behind ultra-fast movements in an interview with associate editor Katie L. Burke:

PODCASTS: Expanding With the Cosmos
Using the Atacama Cosmology Telescope (ATC), a 6.5-meter microwave collector in Chile, cosmologists are piecing together the early history of the known universe. In an exclusive American Scientist interview, Arthur Kosowsky—a member of the ATC team and a professor in the Department of Physics and Astronomy at the University of Pittsburgh—discusses how he is using ATC to reach back in time billions of years to search for gravitational waves that could verify inflation and reveal unprecedented details about how the cosmos was born.
