| Astronomer uncovers the hidden identity of an exoplanet Posted: 01 Jul 2013 01:39 PM PDT Hovering about 70 light-years from Earth –- that's "next door" by astronomical standards –– is a star astronomers call HD 97658, which is almost bright enough to see with the naked eye. But the real "star" is the planet HD 97658b, not much more than twice the Earth's diameter and a little less than eight times its mass. HD 97658b is a super-Earth, a class of planet for which there is no example in our home solar system. |
| Posted: 01 Jul 2013 12:18 PM PDT Superconductivity is a rare physical state in which matter is able to conduct electricity -- maintain a flow of electrons -- without any resistance. This phenomenon can only be found in certain materials under specific low-temperature and high-pressure conditions. New research found unexpected superconductivity that could help scientists better understand the structural changes that create this rare phenomenon. |
| Posted: 01 Jul 2013 12:16 PM PDT When it comes to economics versus psychology, score one for psychology. Economists argue that markets usually reflect rational behavior -- with the dominant players in a market, such as hedge-fund managers, almost always making well-informed and objective decisions. But psychologists say that markets are not immune from human irrationality. A new analysis supports the latter case, showing that markets are indeed susceptible to psychological phenomena. |
| Superconductor created from solvent Posted: 01 Jul 2013 12:16 PM PDT Researchers have turned a fairly common non-metallic solvent into a superconductor capable of transmitting electrical current with none of the resistance seen in conventional conductors. |
| Nuke test radiation can fight poachers who kill elephants, rhinos, hippos Posted: 01 Jul 2013 12:14 PM PDT Researchers have developed a new weapon to fight poachers who kill elephants, hippos, rhinos and other wildlife. By measuring radioactive carbon-14 deposited in tusks and teeth by open-air nuclear bomb tests, the method reveals the year an animal died, and thus whether the ivory was taken illegally. |
| Cloud behavior expands habitable zone of alien planets Posted: 01 Jul 2013 10:51 AM PDT A new study that calculates the influence of cloud behavior on climate doubles the number of potentially habitable planets orbiting red dwarfs, the most common type of stars in the universe. |
| NASA decommissions its galaxy hunter spacecraft Posted: 01 Jul 2013 08:06 AM PDT NASA has turned off its Galaxy Evolution Explorer (GALEX) after a decade of operations in which the venerable space telescope used its ultraviolet vision to study hundreds of millions of galaxies across 10 billion years of cosmic time. |
| Teaching a computer to play concentration advances security, understanding of the mind Posted: 01 Jul 2013 07:08 AM PDT Computer science researchers have programmed a computer to play the game Concentration (also known as Memory). The work could help improve computer security -- and improve our understanding of how the human mind works. |
