NEW YORK - Less than two weeks after graduating from the New York City police academy, more than 1,500 rookie officers have a daunting first assignment: helping to protect Times Square on New Year s Eve.The deployment is just one of an array of security measures 151; many visible, many not 151; that the New York Police Department rolls out each year for the event that turns the Crossroads of the World into a massiv

The yearly ritual also means worrying about potential terror threats.

Using this data, the scie

The study demonstrates for the first time a direct connection between magnetic turbulence in the disk, the formation of a billion-degree corona above and below the disk, and the production of hard X-rays around an actively feeding black hole.
