| Posted: 25 Sep 2012 12:21 PM PDT By studying amphibians that can regenerate missing limbs, scientists have discovered that it isn't enough to activate genes that kick start the regenerative process. In fact, one of the first steps is to halt the activity of so-called jumping genes. In a new paper, researchers show that in the Mexican axolotl, jumping genes have to be shackled or they might move around in the genomes of cells in the tissue destined to become a new limb, and disrupt the process of regeneration.  |
| Urban coyotes never stray: New study finds 100 percent monogamy Posted: 25 Sep 2012 11:25 AM PDT Coyotes living in cities don't ever stray from their mates, according to a new study. The finding sheds light on why the North American cousin of the dog and wolf, which is originally native to deserts and plains, is thriving today in urban areas.  |
| U.S. presidential candidates could get medieval with 'indirect aggression' debate tactics Posted: 25 Sep 2012 07:25 AM PDT As Barack Obama and Mitt Romney prepare to square off in a series of presidential debates, the candidates and their running mates could go medieval on their opponents by using a rhetorical technique that dates back to Nordic and Germanic legends of the Middle Ages, says a scholar of medieval literature.  |
| Emotion detector enables design of tailor-made election campaigns Posted: 25 Sep 2012 06:16 AM PDT Messages, attires, gestures, themes or melodies that are liked by the public are some of the aspects that guarantee the success of a political party. Researchers are now helping to define such feelings thanks to Sentient, a "feelings detector". This device issues reports on the positive or negative perception of some people to the stimuli of their environment. Thus, Sentient provide campaign managers with the necessary information to determine, adjust or even enhance the elements influencing voters' intentions.  |
| Musical clues to the truth about female sleuths Posted: 25 Sep 2012 06:15 AM PDT By analyzing the soundtracks of 1940s film noir thrillers, a musicologist can track changing attitudes to women -- moving away from the classic femme fatale and love interest to the independent female sleuth and action heroine.  |
| Mars-like places on Earth give new insights into Rover data and conditions for life Posted: 24 Sep 2012 11:27 AM PDT Life thrives on Planet Earth. In even the most inhospitable places – the freezing Antarctic permafrost, sun-baked saltpans in Tunisia or the corrosively acidic Rio Tinto in Spain – pockets of life can be found. Some of these locations have much in common with environments found on Mars, as discovered by orbiters and rovers exploring the surface. Researchers have made a series of field trips to the most Mars-like places on Earth.  |
| Windshield wiper for Mars dust developed: Actuator moved by materials that have shape memory Posted: 24 Sep 2012 07:18 AM PDT A team of researchers in Spain has developed a device that works as a windshield wiper to eliminate Mars dust from the sensors on the NASA spacecrafts that travel to the Red Planet.  |
