Electromagnetic devices, from power drills to smart-phones,
require an electric current to create the magnetic fields that
allow them to function. But researchers at the University of
California, Los Angeles have developed a method for switching
tiny magnetic fields on and off with an electric field—a sharp
departure from the traditional approach of running a current
through a wire. The new composite can control magneto-electric
activity at a scale of just 10 nm. Many collisions occur between
asteroids and other objects in our solar system, but... Excess
heat, like that generated by extended use of a computer or other
device,... A team of scientists in the United States has combine
three different imaging methods... Bacteria on a surface wander
around and often organize into highly resilient communities
known as biofilms. It turns out that they organize in a rich-
get-richer pattern similar to the distribution of wealth in the
U.S. economy, according to a new study. A research team led by
UCLA bioengineers has
