| Jurassic jaws: How ancient crocodiles flourished during the age of the dinosaurs Posted: 10 Sep 2013 05:55 PM PDT New research has revealed the hidden past of crocodiles, showing for the first time how these fierce reptiles evolved and survived in a dinosaur dominated world.  |
| Comet discovered hiding in plain sight: Near-Earth asteroid is really a comet Posted: 10 Sep 2013 02:14 PM PDT For 30 years, a large near-Earth asteroid wandered its lone, intrepid path, passing before the scrutinizing eyes of scientists while keeping something to itself: (3552) Don Quixote, whose journey stretches to the orbit of Jupiter, now appears to be a comet.  |
| Organic molecules found in Sutter's Mill meteorite, not previously found in any meteorites Posted: 10 Sep 2013 02:14 PM PDT An important discovery has been made concerning the possible inventory of molecules available to the early Earth. Scientists found that the Sutter's Mill meteorite, which exploded in a blazing fireball over California last year, contains organic molecules not previously found in any meteorites. These findings suggest a far greater availability of extraterrestrial organic molecules than previously thought possible, an inventory that could indeed have been important in molecular evolution and life itself.  |
| Scientists create new memories by directly changing the brain Posted: 10 Sep 2013 11:23 AM PDT By studying how memories are made, neurobiologists created new, specific memories by direct manipulation of the brain, which could prove key to understanding and potentially resolving learning and memory disorders.  |
| Possibility of selectively erasing unwanted memories Posted: 10 Sep 2013 11:09 AM PDT For the first time, scientists have been able to erase dangerous drug-associated memories in mice and rats without affecting other more benign memories. The surprising discovery points to a clear and workable method to disrupt unwanted memories while leaving the rest intact.  |
| Panda poop microbes could make biofuels of the future Posted: 10 Sep 2013 11:09 AM PDT Unlikely as it may sound, giant pandas Ya Ya and Le Le in the Memphis Zoo are making contributions toward shifting production of biofuels away from corn and other food crops and toward corn cobs, stalks and other non-food plant material.  |
| Extreme life forms: Life found in the sediments of an Antarctic subglacial lake for the first time Posted: 10 Sep 2013 07:49 AM PDT Evidence of diverse life forms dating back nearly a hundred thousand years has been found in subglacial lake sediments by scientists. The possibility that extreme life forms might exist in the cold and dark lakes hidden kilometers beneath the Antarctic ice sheet has fascinated scientists for decades.  |
| New evidence that orangutans and gorillas can match images based on biological categories Posted: 10 Sep 2013 06:52 AM PDT The ability to form a general concept that connects what we know about the members of a category allows humans to respond appropriately when they encounter a novel member of that category. At an early age, children form categories to, for example, differentiate animals from inanimate objects and to differentiate dogs from cats. New research shows that other apes may form similar categories to represent different types of animals.  |
| Maya decapitated and dismembered their enemies Posted: 10 Sep 2013 06:49 AM PDT Researchers have discovered a mass grave in an artificial cave in the historical Maya city of Uxul (Mexico). Marks on the bones indicate that the individuals buried in the cave were decapitated and dismembered around 1,400 years ago. The scientists assume that the victims were either prisoners of war or nobles from Uxul itself.  |
| Motorized microscopic matchsticks move in water with sense of direction Posted: 10 Sep 2013 06:49 AM PDT Chemists, physicists and computer scientists have come together to devise a new powerful and very versatile way of controlling the speed and direction of motion of microscopic structures in water using what they have dubbed chemically 'motorized microscopic matchsticks'.  |
| Water hidden in the Moon may have proto-Earth origin Posted: 10 Sep 2013 06:39 AM PDT Water found in ancient Moon rocks might have actually originated from the proto-Earth and even survived the Moon-forming event. Scientists have studied the amount of water within lunar rocks returned during the Apollo missions.  |
