Coronal Holes: The (Rarely Round) Gaps In The Sun's Atmosphere

NASA's Solar Dynamics Observatory captured this picture of the sun on June 18. The dark blue area in the upper left quadrant of the sun is a huge coronal hole more than 400,000 miles across.

There's a hole in the sun's corona. But don't worry — that happens from time to time.

Dogs often get credit for being humans' constant companions. But dogs have nothing on tuberculosis bacteria.

Most parents yell at their kids at some point. It often feels like the last option for getting children to pay attention and shape up.

But harsh verbal discipline may backfire. Teenagers act worse if they're yelled at, a study finds.

Researchers asked parents of 13-year-olds in the Philadelphia area how often in the past year they'd yelled, cursed or called the kid "dumb or lazy or some other word like that" after he or she had done something wrong.
