Aerospace and aircraft companies as well as the military have been challenged to find ways of effectively shielding sensitive electronic equipment such as radar and radios from electromagnetic interference (EMI) without adding a lot of weight to aircraft and satellites (the more massive they are, the more fuel they need to stay in the air or achieve orbit, respectively). Whereas EMI can lead to headaches like erased data and loss of connectivity for casual computer and cell phone users, the problem is far more serious in aircraft, where interference can jam cockpit radio and radar signals, preventing pilots from sending and receiving crucial information.

American homes and their energy consumption account for nearly 40 percent of U.S. emissions, 626 million metric tons of carbon in 2005 alone. But 33 simple actions--ranging from improving the insulation to carpooling--could cut those annual carbon emissions by 123 million metric tons. That savings would more than entirely offset emissions from petroleum refineries, iron and steel works, and aluminum smelters combined. [More]

Technology that can identify partial, distorted, scratched, smudged, or otherwise warped fingerprints in just a few seconds has just scored top marks in the world's two toughest technical fingerprint tests. The technology is also being rapidly taken up by the UK building trade who are delighted to have fingerprint technology which can cope with the often worn and ravaged builders' thumbprints.

A robot is currently building a looping brick wall right in the middle of New York City. Over a period of three weeks, passers-by can watch the "Pike Loop" installation in the making on a traffic island.

Researchers here have discovered the pivotal role that volcanoes played in a deadly ice age 450 million years ago. Perhaps ironically, these volcanoes first caused global warming -- by releasing massive amounts of carbon dioxide into the atmosphere. When they stopped erupting, Earth's climate was thrown off balance, and the ice age began.

Exercise can help smokers quit because it makes cigarettes less attractive. A new study shows for the first time that exercise can lessen the power of cigarettes and smoking-related images to grab the attention of smokers.

A new study by researchers in the UK has discovered abnormalities in the white matter of the brain that seem to be critical for the timing of schizophrenia.
