| Posted: 28 Dec 2011 05:42 AM PST Given the incredible amounts of energy in a supernova explosion -- as much as the sun creates during its entire lifetime -- another erroneous doomsday theory is that such an explosion could happen in 2012 and harm life on Earth. However, given the vastness of space and the long times between supernovae, astronomers can say with certainty that there is no threatening star close enough to hurt Earth. |
| Posted: 28 Dec 2011 05:40 AM PST One of the most bizarre theories about 2012 has built up with very little attention to facts. This idea holds that a cosmic alignment of the sun, Earth, the center of our galaxy -- or perhaps the galaxy's thick dust clouds -- on the winter solstice could for some unknown reason lead to destruction. Such alignments can occur but these are a regular occurrence and can cause no harm (and, indeed, will not even be at its closest alignment during the 2012 solstice.) |
| Record conductivity achieved in strained lattice organic semiconductor Posted: 21 Dec 2011 11:03 AM PST By packing molecules closer together, chemical engineers have dramatically improved the electrical conductivity of organic semiconductors. The advance could herald flexible electronics, more efficient solar panels, and perhaps even better television screens. |
| Landmark discovery has magnetic appeal for scientists Posted: 21 Dec 2011 11:03 AM PST A fundamental problem that has puzzled generations of scientists has finally been solved after more than 70 years. |
| Prototype device measures absolute optical power in fiber at nanowatt levels Posted: 21 Dec 2011 07:58 AM PST Researchers have demonstrated the first prototype device that measures optical power delivered through optical fiber at nanowatt levels. |
| Sensor improvement brings analysis method into mainstream Posted: 21 Dec 2011 07:58 AM PST An advance in sensor design could unshackle a powerful yet high-maintenance technique for exploring material, expanding the scope of neutron interferometry from a test of quantum mechanics to a tool for industry. |
