+ - First Evidence of Another Universe? 2

Submitted by blamanj
blamanj writes "Three months ago, astronomers announced the discovery of a large hole at the edge of our universe. Now, Dr. Laura Mersini-Houghton thinks she knows what that means. (Subscription req'd at New Scientist site, there's also an overview here.) According to string theory, there are many universes besides our own. Her team says that smaller universes are positioned at the edge of our universe, and because of gravitational interactions, they can be observed, and they're willing to make a prediction. The recently discovered void is in the northern hemisphere. They contend another one will be found in the southern hemisphere."

+ - The first image taken with an ultra low field MRI->

KentuckyFC writes "MRI machines are about to get smaller, much smaller. Most of their bulk is taken up by the huge superconducting magnets required to generate fields of about a Tesla. Now a team at the Los Alamos National Lab in New Mexico has built a machine that can produce images using a field of only a few microTesla. So giant superconducting magnets aren't necessary, a development that has the potential to make MRI machines much smaller, perhaps even suitcase sized. Today, the team has posted sections of the first 3D brain image taken with the device (abstract, pdf)."
