Synthetic Magnetic Field Shows That Magnets With One Pole — Monopole — May Exist
Feb 01, 2014 16:53 PM E
Physicists have long believed that magnets can exist with only one pole as opposed to one with a north and south pole. In a new study, they were able to create a magnetic field that contained only monopoles.

Why Stephen Hawking Says Black Holes As We Know Them Don't Exist
Jan 24, 2014 16:17 PM E
Stephen Hawking's solution to a black hole paradox tosses out everything that was once awesome about black holes: their ability to suck up matter and never let it out, including light. Under the new model, Hawking suggests that matter comes and goes from black holes more or less as it pleases.

Opportunity Rover Finds Mysterious Mars Rock: Where Did It Come From?
Jan 17, 2014 11:03 AM E
A rock has appeared in front of the Mars rover Opportunity, and NASA isn't sure where it came from. In two photos of the same spot on Mars, taken 12 Martian days apart, a rock appears suddenly in the later photo. NASA Mars Exploration Rover lead scientist Steve Squyres suspects the rover may have shifted around, kicking the rock in front of Opportunity's camera.
