| Mississippi River flows backwards due to Isaac Posted: 29 Aug 2012 04:24 PM PDT Strong winds and storm surge from Hurricane Isaac's landfall forced the Mississippi River to flow backwards for nearly 24 hours on Tuesday, Aug. 28. The USGS streamgage at Belle Chasse, Louisiana, showed the Mississippi River flowing upstream at 182,000 cubic feet per second, surging to 10 feet above than its previous height. Average flow for the Mississippi River at Belle Chase is about 125,000 cfs towards the Gulf of Mexico. |
| 'Nano machine shop' shapes nanowires, ultrathin films Posted: 29 Aug 2012 02:21 PM PDT A new "nano machine shop" that shapes nanowires and ultrathin films could represent a future manufacturing method for tiny structures with potentially revolutionary properties. |
| Rare find: Feathered dinosaur feasted on flying food Posted: 29 Aug 2012 02:19 PM PDT Researchers found evidence that a feathered, but flightless dinosaur was able to snag and consume small flying dinosaurs. |
| Eyeless Australian fish have closest relatives in Madagascar Posted: 29 Aug 2012 12:12 PM PDT Researchers have discovered that two groups of blind cave fishes on opposite sides of the Indian Ocean are each other's closest relatives. Through comprehensive DNA analysis, the researchers determined that these eyeless fishes, one group from Madagascar and the other from similar subterranean habitats in Australia, descended from a common ancestor before being separated by continental drift nearly 100 million years ago. |
| Computer viruses could take a lesson from showy peacocks Posted: 29 Aug 2012 12:12 PM PDT Computer viruses are constantly replicating throughout computer networks and wreaking havoc. But what if they had to find mates in order to reproduce? Researchers have now created the digital equivalent of spring break to see how mate attraction played out through computer programs. |
| Bonanza of black holes, hot DOGs: NASA's WISE survey uncovers millions of black holes Posted: 29 Aug 2012 11:45 AM PDT NASA's Wide-field Infrared Survey Explorer (WISE) mission has led to a bonanza of newfound supermassive black holes and extreme galaxies called hot DOGs, or dust-obscured galaxies. Images from the telescope have revealed millions of dusty black hole candidates across the universe and about 1,000 even dustier objects thought to be among the brightest galaxies ever found. These powerful galaxies, which burn brightly with infrared light, are nicknamed hot DOGs. |
| Internet addiction: Causes at the molecular level Posted: 29 Aug 2012 07:34 AM PDT Internet addiction is not a figment of our imagination, researchers in Germany say. Over the past years, the researchers have interviewed a total of 843 people about their Internet habits. An analysis of the questionnaires shows that 132 men and women in this group exhibit problematic behavior in how they handle the online medium; all their thoughts revolve around the Internet during the day, and they feel their wellbeing is severely impacted if they have to go without it. |
| Posted: 29 Aug 2012 06:42 AM PDT An ant biologist and a computer scientist has revealed that the behavior of harvester ants as they forage for food mirrors the protocols that control traffic on the Internet. |
| Shifty, but secure eyes: New biometric security system Posted: 29 Aug 2012 03:48 AM PDT A biometric security system based on how a user moves their eyes is being developed by technologists in Finland. Researchers explain how a person's saccades, their tiny, but rapid, involuntary eye movements, can be measured using a video camera. The pattern of saccades is as unique as an iris or fingerprint scan but easier to record and so could provide an alternative secure biometric identification technology. |
