There's evidence that Venus, Earth, and Mars all had oceans of water in their past. Why is Earth the only rocky planet that still has oceans today? Scientists think that part of the reason might have to do with the way some planets are like giant magnets.

Rethinking Energy: Is it time to reinvent the wheel?
In the 1970s teenager Frank Nasworthy actually did reinvent the wheel and it revolutionized skateboarding. Today, Goodyear and others are trying to reinvent the wheel once again. If they succeed, we can eliminate the need for axles on cars and replace wheels with 360-degree spheres held in place by magnets. Sometimes we actually do need to reinvent the wheel to move forward. In today’s economy and climate, we may have to think about reinventing the way we produce energy. Rather than drilling for it down deep beneath the surface, can we harvest from the abundant energy found in the environments around us?
