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. Coronal holes are areas of the sun's outermost atmospheric layer — the corona — where the magnetic field opens up and solar material quickly flows out.

Originally published on Thu September 5, 2013 5:43 pm

Cats have come a long way from being animals charged with catching mice to treasured, adorable creatures that snuggle with us in our beds. But this relatively new arrangement is creating issues for cats and the people who live with them.

John Bradshaw has studied the history of domesticated cats and how the relationship between people and cats has changed. He's the author of the new book Cat Sense: How the New Feline Science Can Make You a Better Friend to Your Pet, which is a follow-up to his book Dog Sense.

It sounded a bit far-fetched, and perhaps it was.

Iran's former President Mahmoud Ahmadinejad denied the Holocaust and threatened to wipe Israel off the map.

Parents' Harsh Words Might Make Teen Behaviors Worse

Sure you're steamed. But teenagers tend to meet harsh words with even worse behavior, a study says.

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.
