Brain Freeze

sciammind_cover_200904Some 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.

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.

With A Little Help

The walk to and from school can’t be uphill both ways, but going it alone might make it seem that way. When judging the steepness of a hill, people overestimated its angle more when alone than when they were accompanied by—or even thinking about—a friend, reports an international group of researchers led by Simone Schnall of University of Plymouth in England in the Journal of Experimental Social Psychology in May. The longer the volunteers had been friends with their companions, the less steep the hill seemed.

Seismic “Noise”–Oil Prospecting Data Could Decipher Ocean Mixing

Three decades ago researchers discovered what are essentially enormous saltwater lakes in the Atlantic Ocean. These “lakes,” called meddies, are gently spinning lenses of water up to 100 kilometers across and one kilometer thick. They float a few hundred meters below the surface of the ocean. Such large, warm bodies, which turned out to come from the Mediterranean Sea, should have an impact on heat exchange in the ocean—and on the planet’s climate. But efforts to study meddies—conventionally by dropping probes that directly measure the ocean’s temperature, salinity and velocity—have proved too costly, infrequent and spread out to reveal how the meddies dissipate their heat.
