Although liquid water covers a majority of Earth's surface, scientists are still searching for planets outside of our solar system that contain water. Researchers at Caltech and several other institutions have used a new technique to analyze the gaseous atmospheres of such extrasolar planets and have made the first detection of water in the atmosphere of the Jupiter-mass planet orbiting the nearby star tau Boötis.
If dark matter exists, it's not hiding out in our neighbourhood, baffled scientists have revealed.
Scientists say they've developed a laser that can detect roadside bombs - the biggest killers of colaition forces in Iraq and Afghanistan.
Northwestern University scientists say they've taken a big step towards a handheld device for detecting nuclear weapons and materials such as a 'bomb in a suitcase'.
