| Super rats are immune to conventional poisons, UK experts find Posted: 18 Oct 2012 09:28 AM PDT Scientists in the United Kingdom have noticed a mounting problem of destructive "super rats" immune to conventional poison.  |
| World's largest subwoofer: Earthquakes 'pump' ground to produce infrasound Posted: 18 Oct 2012 07:29 AM PDT Earthquakes sway buildings, buckle terrain, and rumble -- both audibly and in infrasound, frequencies below the threshold of human hearing. New computer modeling by a team of researchers indicates that most of the low-frequency infrasound comes from an unexpected source: the actual "pumping" of Earth's surface. The researchers confirmed their models by studying data from an actual earthquake.  |
| Dinosaur-era acoustics: Global warming may give oceans the 'sound' of the Cretaceous Posted: 18 Oct 2012 07:29 AM PDT Global temperatures directly affect the acidity of the ocean, which in turn changes the acoustical properties of sea water. New research suggests that global warming may give Earth's oceans the same hi-fi sound qualities they had more than 100 million years ago, during the Age of the Dinosaurs.  |
| How flick knife thumbs help Japan's rare fighting frogs Posted: 18 Oct 2012 07:01 AM PDT Combat-ready spikes which shoot from fingers sounds like the weaponry of a comic book hero, but a Japanese scientist has found exactly this in a rare breed of frog. The discovery reveals how the Otton frog uses spikes which protrude from a false thumb for both combat and mating.  |
