Scientists working for NASA previewed the next big step in the latest mission to the Red Planet: The precision setdown of the rover Curiosity in a crater that contains the towering Mount Sharp. "I see it as an extraordinary opportunity to get a bearing on our own existence on Earth," said one scientist, anticipating the Aug. 6 arrival date. Summary.
The mammals can be taught to react like humans plugging their ears when jets fly over, researchers found in limited trials.
If you think you can tell if someone is lying from their eyes, think again.

Supporting a controversial view of how humans might have populated the Western Hemisphere, geneticists have found that groups from Asia traveled over the Bering Strait into North America in at least three separate migrations beginning more than 15,000 years ago -- not in a single wave, as has been widely thought.
What's next: We're about to find out if there will be a way anytime soon to slow the course of Alzheimer's disease. Results are due in about a month from key studies of two drugs that aim to clear the sticky plaque gumming up patients' brains.

It was a provocative finding: strange bacteria in a California lake that thrived on something completely unexpected — arsenic. What it suggested is that life, a very different kind of life, could possibly exist on some other planet.

Tai chi, the martial art that has become popular as a gentle mind-body workout, may have another benefit: Helping to increase the size of the brain. And brain growth, scientists hope, could unlock a clue to staving off and even preventing dementia.
About 460 light-years away in the constellation Centaurus, a thick disk of dust swirled around a young star named TYC 8241 2652 1, where rocky planets like our own were arising. Then, in less than two years, the disk vanished.
If you're one of thousands who have not fixed computers, you may lose Internet service late Sunday.
If you want to make sure you'll still be able to use the Internet when you wake up Monday, go to www.dcwg.org, click "Detect," and follow the instructions from there. That's the website of the DNS Changer Working Group, set up by court order to fix a bunch of servers that had been taken over by an Estonian crime ring to redirect millions of users to rogue websites.
