Study: Good night's sleep cleans out gunk in brain

LOS ANGELES (AP) — Here's a reason to get some shuteye: A new study suggests our brains go on a cleaning spree during sleep, flushing out gunk that builds up while we're awake.

West Nile Virus

Del. reports first human case of West Nile virus

DOVER, Del. (AP) — Delaware public health officials have confirmed the state's first human case of West Nile virus this year.

Officials said Friday that a woman in her early 20s living in New Castle County tested positive for the virus on Wednesday.

For the past five years, the state usually has reported no more than one case per year, but there were nine reported cases of West Nile infection last year.

The virus is transmitted by mosquitoes, but officials say roughly 80 percent of people infected with West Nile virus will not become ill.

Rocket Launch

NASA scrubs launch of 2 rockets from Va

WALLOPS ISLAND, Va. (AP) — NASA has canceled a planned launch of two rockets from the Eastern Shore of Virginia due to poor weather conditions.

NASA had hoped to launch the Black Brant V and Terrier-Improved Orion 15 seconds apart on Friday in support of the Daytime Dynamo experiment. This is the third attempt that's had to be scrubbed due to poor weather or scientific conditions.

NASA says the project is designed to study a global electrical current called the dynamo, which sweeps through the ionosphere.
