| Nuclear fragments could help uncover the origins of life-supporting planets Posted: 11 Dec 2014 06:00 PM PST New research describes how recreating isotopes that occur when a star explodes, can help physicists understand where life-supporting elements may be found in space. |
| Swarms of Pluto-size objects kick up dust around adolescent Sun-like star Posted: 11 Dec 2014 01:25 PM PST Astronomers may have detected the dusty hallmarks of an entire family of Pluto-size objects swarming around an adolescent version of our own Sun. By making detailed observations of the protoplanetary disk surrounding the star known as HD 107146, the astronomers detected an unexpected increase in the concentration of millimeter-size dust grains in the disk's outer reaches. This surprising increase, which begins remarkably far -- about 13 billion kilometers -- from the host star, may be the result of Pluto-size planetesimals stirring up the region, causing smaller objects to collide and blast themselves apart. |
| Basic rules for construction with a type of origami Posted: 11 Dec 2014 11:26 AM PST Origami is capable of turning a simple sheet of paper into a pretty paper crane, but the principles behind it can be applied to making a microfluidic device or for storing a satellite's solar panel in a rocket's cargo bay. Researchers are turning kirigami, a related art form that allows the paper to be cut, into a technique that can be applied equally to structures on those vastly divergent length scales. |
| Chickens and turkeys 'closer to dinosaur ancestors' than other birds Posted: 11 Dec 2014 11:26 AM PST New research suggests that chickens and turkeys have experienced fewer gross genomic changes than other birds as they evolved from their dinosaur ancestor. |
| Tooth loss in birds occurred about 116 million years ago Posted: 11 Dec 2014 11:21 AM PST A question that has intrigued biologists is: Were teeth lost in the common ancestor of all living birds or convergently in two or more independent lineages of birds? A research team used the degraded remnants of tooth genes in birds to determine that teeth were lost in the common ancestor of all living birds more than 100 million years ago. |
| Human DNA shows traces of 40 million-year battle for survival between primate and pathogen Posted: 11 Dec 2014 11:18 AM PST Examination of DNA from 21 primate species – from squirrel monkeys to humans – exposes an evolutionary war against infectious bacteria over iron that circulates in the host's bloodstream. Supported by experimental evidence, these findings demonstrate the vital importance of an increasingly appreciated defensive strategy called nutritional immunity. |
| 3-d maps of folded genome: Catalog of 10,000 loops reveals new form of genetic regulation Posted: 11 Dec 2014 09:44 AM PST In a triumph for cell biology, researchers have assembled the first high-resolution, 3D maps of entire folded genomes and found a structural basis for gene regulation -- a kind of "genomic origami" that allows the same genome to produce different types of cells. |
| Scientists develop solar observatory for use on suborbital manned space missions Posted: 11 Dec 2014 08:55 AM PST Scientists are preparing to unveil a new, miniature portable solar observatory for use onboard a commercial, manned suborbital spacecraft. |
| Researchers detect possible signal from dark matter Posted: 11 Dec 2014 08:55 AM PST Scientists have picked up an atypical photon emission in X-rays coming from space, and say it could be evidence for the existence of a particle of dark matter. If confirmed, it could open up new perspectives in cosmology. |
| Posted: 11 Dec 2014 07:18 AM PST The saga of the Osedax "bone-eating" worms began 12 years ago, with the first discovery of these deep-sea creatures that feast on the bones of dead animals. The Osedax story grew even stranger when researchers found that the large female worms contained harems of tiny dwarf males. |
| The Jaws effect: Biting review finds shark policy based on movie myths Posted: 11 Dec 2014 06:06 AM PST The film "Jaws" has heavily influenced Western Australia's stance on sharks, a review of over a decade of state government policy has found. |
