When it's hot and humid, you probably don't want to move much and aren't very hungry. The same goes for cows; but when they don't eat, farmers lose money.

Researchers at the University of Missouri think they can help avoid those losses. They've produced a new mobile app that can detect the threat of heat stress in cows using nothing more than a smartphone.

"After years maintaining innocence," as Nashville Public Radio says, Gibson Guitar Corp. has agreed to pay a $300,000 penalty, donate $50,000 to a conservation fund and give up its claims to ebony and rosewood worth nearly $262,000 to avoid being criminally prosecuted for importing exotic woods.

A shooting at a Sikh Temple in a suburb of Milwaukee today has left at least seven people dead, including the gunman, police say.

A fierce drought has been scorching crops this summer, but it's still too soon to know exactly how much of a hole it will burn in your wallet.

Stop by most any unirrigated farm across the lower Midwest and you'll see crops in distress. Midwestern corn and soybean farmers are taking a beating during the recent drought, but it's not likely to drive many out of business.

Most of those farmers carry terrific insurance, and the worse the drought becomes, the more individual farmers will be paid for their lost crops. The federal government picks up most of the cost of the crop insurance program, and this year that bill is going to be a whopper.

In 1983, Sally Ride became the first American woman in space. She blasted off aboard Challenger, culminating a long journey that started in 1977 when the Ph.D. candidate answered an ad seeking astronauts for NASA missions.

In a lecture she gave at Berkeley, Ride said she saw the ad on Page 3 of the student newspaper.

"The moment I saw that ad, I knew that's what I wanted to do," she said.
