Space station supply launch called off in Virginia

Oct 28, 2014

CAPE CANAVERAL, Fla. (AP) — A space station delivery mission was called off Monday, just hours after the orbiting lab had to sidestep a piece of treacherous junk.

Orbital Sciences Corp. got to within the 10-minute mark for the Virginia launch of its unmanned Cygnus capsule. But a sailboat ended up in the restricted danger zone, and controllers halted the evening countdown.

The Virginia-based company will try again Tuesday evening.

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

Oct 17, 2013

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.

Though the cleaning was observed in mice, scientists think it happens in people too.

The findings were reported in Friday's issue of the journal Science and may provide new clues to treat Alzheimer's and other brain diseases.

People who are sleep-deprived have trouble learning and making decisions. But despite decades of research, scientists can't agree on the basic purpose of sleep.

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.
