War, natural disasters and climate change are destroying some of the world's most precious cultural sites. Google is trying to help preserve these archaeological wonders by allowing users access to 3D images of these treasures through its site.

But the project is raising questions about Google's motivations and about who should own the digital copyrights. Some critics call it a form of "digital colonialism."

There's going to be a changing of the guard in space. On Tuesday, NASA is launching two new satellites, collectively called GRACE, to replace two that have been retired after 16 years in orbit.

A long time ago in a galaxy far far away, there was a world leader who signaled his desire to create a new branch of the military: the space force.

OK, it wasn't a long time ago, and it was right here on Earth, in the Milky Way galaxy.

Justify is the heavy favorite heading into the 143rd running of the Preakness Stakes at Pimlico Race Course in Baltimore.

Justify is a 1-2 favorite for the Preakness. The Kentucky Derby winner drew the seventh post in Saturday's race — the same post he had at the Derby.

Chimps owned by the National Institutes of Health should be moved from research facilities to retirement sanctuaries unless that relocation is "extremely likely" to shorten their lives, a report issued Friday says.

"Chimpanzees should be relocated to the federal sanctuary system unless relocation would place the chimpanzee's life, safety, and welfare at extreme risk," says the report from a working group convened by the NIH to examine the safety of transferring chimps to retirement homes.

Good morning. I'm David Greene. Wasn't it the movie "2001: A Space Odyssey" when we became afraid technology could outsmart us?

There may be hope for the nearly extinct northern white rhino yet, thanks to the pregnancy of a closely related subspecies.

"Victoria," a southern white rhino in California, was impregnated through artificial insemination, researchers announced on Thursday.

"It's very exciting because this is our first pregnant rhino from artificial insemination here at the San Diego Zoo Safari Park," Barbara Durrant, director of reproductive sciences at the San Diego Zoo Institute for Conservation Research, told NPR.

When a WWE wrestler, especially one known for his demonic antics and a move called the "tombstone piledriver," runs for mayor of your county, you know your election is going to get more attention than usual.

But in Knox County, Tenn., it wasn't the fact that Glenn Jacobs, also known to wrestling fans as Kane, was running for mayor that gained national attention on the county primary day, May 1.

The oceans are getting warmer and fish are noticing. Many that live along U.S. coastlines are moving to cooler water. New research predicts that will continue, with potentially serious consequences for the fishing industry.

The National Highway Traffic Safety Administration announced Wednesday it has launched an investigation into a rear-end collision involving a Tesla in South Jordan, Utah, the Associated Press reported. It marks at least the third investigation into crashes involving the company's cars since March.
