New tests of nanostructured material could lead to better armor

Providing protection against impacts from bullets and other high-speed projectiles is more than just a matter of brute strength. While traditional shields have been made of bulky materials such as steel, newer body armor ...

Space cannon to shoot payloads into orbit (w/ Video)

(PhysOrg.com) -- A physicist has proposed using a 1.1 km (3,600 ft) cannon to deliver cargo into orbit, and says the cost would be around $250 per pound, a massive saving on the $5,000 per pound ($11,000 per kg) it currently ...

Prehistoric Cold Case Hints of Interspecies Homicide

(PhysOrg.com) -- The wound that ultimately killed a Neandertal man between 50,000 and 75,000 years was most likely caused by a thrown spear, the kind modern humans used but Neandertals did not, according to Duke University-led ...

Reconstructing an ancient lethal weapon

Archaeologists are a little like forensic investigators: They scour the remains of past societies, looking for clues in pottery, tools and bones about how people lived, and how they died.

Cosmic impacts might help synthesize organic compounds

Bullets of ice shot at high speeds can deposit organic compounds on surfaces they strike. The new findings suggest that comets might, indeed, have helped deliver key ingredients of life to Earth and perhaps elsewhere, researchers ...
