Some of us sing, and some of us just mouth the lyrics, but we all rely on our brain to coordinate even the simplest motor behaviors. Scientists interested in the brain activity behind motion often use birdsong as a model because certain songs are sung the same way every time, providing a naturally controlled setting for investigation. Now researchers have solved a long-standing mystery about the hierarchy of brain regions essential for birdsong using a chilly technique that could tease out the interconnected processes behind many complex actions.

Duct Tape for the Brain
Kirsten Timmons was navigating a frozen overpass one night when a passing car skidded out of control and slammed into her vehicle. As her car came to a stop, Timmons’s head probably snapped around its own axis, decelerating sharply when it struck the seat-belt holder next to her. Continue reading Duct Tape for the Brain
Oxford Cagey About New Animal Labs
LONDON–When scientists move into new laboratory buildings, their universities often proclaim the event with a ribbon cutting and champagne. Yet when the first mice arrived at the University of Oxford’s new animal research facility last week, officials waited to make the announcement until a press conference here today. Rather than enthusiastically providing details about the building’s inhabitants–animals and researchers included–Oxford officials spent much of the media encounter declining to answer questions and asking that names of those involved with the building not be used.

Internal Waves Beneath The Sea
Seismologist W. Steven Holbrook and oceanographer Raymond Schmitt might be forgiven for talking past each other aboard a research cruise. Oceanographers normally drop probes overboard, measuring the ocean’s temperature, chemistry and motion. To seismologists, however, the ocean is in the way of their measurements: They typically tune their microphones to detect echoes from below the seafloor in search of clues about Earth’s structure. But over the past five years, Holbrook and Schmitt have learned to listen to each other — and to apply seismic techniques to hear hints of the ocean’s structure.
