We’ve seen movies about “storm chasers,” who chase tornadoes in battered pick-ups, risking their lives in order to learn more about these destructive whirlwinds. We don’t expect the problem to be solved by a scientist brainstorming from his home in Del Mar, California, an area that never experiences tornadoes.

Each year over 1,000 tornadoes rip through America, killing over 100 people. Ben Eastlund, a Star Wars defense programscientist, thinks he has found a way to eliminate them for good.

Somewhere beneath the shallow waters near Tybee Island, 12 miles east of Savannah, lies a 7,600 pound unexploded nuclear bomb that was dropped by a crippled Air Force plane in 1958. It’s lost somewhere in Wassaw Sound, the place where the 1996 Olympic sailing competition was held.

The Air Force says the bomb isn’t dangerous, because it’s missing the plutonium capsule needed to cause a nuclearexplosion, although it still contains radioactive uranium and has the explosive power of 400 pounds of TNT. “The bomboff the coast of Savannah is not capable of a nuclear explosion,” said Major Cheryl Law, an Air Force spokesperson. As for the uranium inside the bomb, “to have that hurt you, you would actually have to ingest it.”

Scientists have discovered the oldest mineral ever found on Earth, provingthat the Earth had oceans and continents just 50 million years after a giantimpact melted the entire planet. An asteroid the size of Mars broke off apiece of the Earth that became the Moon over 4 ? billion years ago. The Moonmade higher forms of life possible on Earth, since its counter-rotationslows down the high-speed winds that would normally sweep along the surface.

Analysis of a tiny zircon crystal found in the ancient and remote hills ofWestern Australia shows that it is a little less than 4 ? billion years old,over 100 million years older than the next-oldest known fragment of Earth,and that it formed only about 50 million years after the asteroid hit.
