| Reign of the giant insects ended with the evolution of birds Posted: 04 Jun 2012 12:57 PM PDT Giant insects ruled the prehistoric skies during periods when Earth's atmosphere was rich in oxygen. Then came the birds. After the evolution of birds about 150 million years ago, insects got smaller despite rising oxygen levels, according to a new study. |
| Mosquitoes fly in rain thanks to low mass Posted: 04 Jun 2012 12:55 PM PDT Even rain can't deter mosquitoes. The blood-sucking insect can fly in a downpour because of its strong exoskeletons and low mass render it impervious to falling drops. Researchers determined this using high-speed videography. |
| Molecular algebra in mammalian cells Posted: 04 Jun 2012 06:28 AM PDT Researchers have reprogrammed mammalian cells in such a way as to perform logical calculations like a pocket calculator. The cells owe this ability to one of the most complex gene networks that has ever been incorporated into a higher cell. |
| Search engine for social networks based on the behavior of ants Posted: 04 Jun 2012 06:28 AM PDT Researchers are developing an algorithm, based on ants' behavior when they are searching for food, which accelerates the search for relationships among elements that are present in social networks. One of the main technical questions in the field of social networks, whose use is becoming more and more generalized, consists in locating the chain of reference that leads from one person to another, from one node to another. The greatest challenges that are presented in this area is the enormous size of these networks and the fact that the response must be rapid. |
