For decades, many scientists have criticized string theory, pointing out that it does not make predictions by which it can be tested. Now, researchers at Carnegie Mellon University; the University of California, San Diego; and The University of Texas at Austin have developed a test of string theory. Their test, described in the Jan. 26 Physical Review Letters, involves measurements of how elusive high-energy particles scatter during particle collisions.

A comprehensive new MIT-led study of the potential for geothermal energy within the United States has found that mining the huge amounts of heat that reside as stored thermal energy in the Earth's hard rock crust could supply a substantial portion of the electricity the United States will need in the future, probably at competitive prices and with minimal environmental impact.

If indeed "a diamond is forever," the most primitive origins of Earth's so-called black diamonds were in deep, universal time, geologists have discovered. Black diamonds came from none other than interstellar space.

NASA moved forward in 2006 to extend humanity's exploration of the solar system and learn more about the universe and our home planet. The space shuttle got back to work building the International Space Station, and the agency began developing the next generation of spacecraft and outlined plans for returning to the moon as a stepping stone toward Mars. Space science missions found new evidence of water on Mars, sent the first-ever probes toward Pluto, brought back dust from a comet and launched new instruments to study the sun and the weather on Earth.
Next Stop - The Moon
America's Vision for Space Exploration, the long-term plan for sending humans to Mars and beyond, moved ahead in August with the selection of Lockheed Martin

The theorists who first created the mathematics that describe the behavior of the recently announced "invisibility cloak" have revealed a new analysis that may extend the current cloak's powers, enabling it to hide even actively radiating objects like a flashlight or cell phone.

Neutrons -- the tiny particles that match with protons to form the innards of nearly every atom in the universe -- decay when left to fend for themselves outside an atomic nucleus. For decades, researchers have predicted but never proved that roughly 1 in 1,000 of those decays will produce light in the form of an energetic photon.
