How GPS Can Keep Track of Earthquakes and Flooding
Data synthesis and sensor coverage make for better monitoring of natural disasters.We usually think of GPS as a way to find out where we are and how to get where we’re going. But over the past couple of years, researchers have discovered that GPS, when combined with sensors such as accelerometers and barometers, can be an important tool for evaluating and possibly predicting earthquakes and flash floods.

Curiosity Finds Evidence Of Ancient Freshwater Lake On Mars
"It's the kind of water where if you were really dying, you could drink it, but you probably wouldn't bottle it for resale," says the chief scientist of the Curiosity mission. Scientists say the lake could have sustained life billions of years ago.

Quake In Central Pakistan Makes New Island
A large earthquake shook a remote part of central Pakistan Tuesday, and so far local authorities have only reported a few dozen fatalities so far. But according to estimates by the U.S. Geological Survey, the death toll could be far higher. The quake also gave rise to a mysterious island off the coast of Pakistan. The island was likely created by frozen methane that was shaken loose by the shaking. It pushed its way to the surface and created a muddy piece of land that will soon be washed away.

Estimate for uranium facility goes from $600 million to $11.6 billion
It would be one of the largest nuclear weapons investments since World War II. A watchdog group says the work – which may not be needed – can be done for less elsewhere.The cost of a proposed uranium processing facility for nuclear weapons in Oakridge, Tenn., has soared as high as $11.6 billion — 19 times the original estimate — even as critics accuse the Energy Department of overstating the need for spare bomb parts.
