| Mars Science Laboratory: NASA launches most capable and robust rover to Red Planet Posted: 26 Nov 2011 12:53 PM PST NASA began a historic voyage to Mars with the Nov. 26 launch of the Mars Science Laboratory, which carries a car-sized rover named Curiosity. Liftoff from Cape Canaveral Air Force Station aboard an Atlas V rocket occurred at 10:02 a.m. EST (7:02 a.m. PST).  |
| Charge separation in a molecule consisting of two identical atoms: Size matters Posted: 25 Nov 2011 01:09 PM PST Physicists have now shown the first experimental proof of a molecule consisting of two identical atoms that exhibits a permanent electric dipole moment. This observation contradicts the classical opinion described in many physics and chemistry textbooks.  |
| Supercool: Water doesn't have to freeze until -55 F Posted: 23 Nov 2011 10:31 AM PST We drink water, bathe in it and we are made mostly of water, yet the common substance poses major mysteries. Now, University of Utah chemists may have solved one enigma by showing how cold water can get before it absolutely must freeze: 55 degrees below zero Fahrenheit.  |
