| Most vertebrates -- including humans -- descended from ancestor with sixth sense Posted: 11 Oct 2011 01:30 PM PDT A new study that caps more than 25 years of work finds that the vast majority of vertebrates -- some 30,000 species of land animals (including humans) and a roughly equal number of ray-finned fishes -- descended from a common ancestor that had a well-developed electroreceptive system.  |
| Fall market jitters a SAD thing: Less daylight in fall may lead to depressed markets Posted: 11 Oct 2011 10:20 AM PDT It's no surprise to researchers that financial market dips and crashes typically happen in the fall. Researchers now show that people who experience seasonal depression shun financial risk-taking during seasons with diminished daylight but are more willing to accept risk in spring and summer. Seasonal depression may be sufficiently powerful to move financial markets.  |
| X-ray camera makes A-grade particle detector Posted: 11 Oct 2011 09:12 AM PDT Combining an off-the-shelf X-ray camera with a thin piece of carbon foil yields a device that can detect high-energy organic atoms and heavy molecules better than the typical devices used for these jobs, with potential benefits ranging from the science of cancer treatment to star chemistry.  |
| New mathematical model explains patterns of human movement by considering the costs Posted: 11 Oct 2011 09:12 AM PDT People decide to take trips for a dauntingly complex mix of reasons, but out of the individual chaos of dry-cleaning pick-ups, pizza dinners, and European vacations, a new mathematical model has emerged. It finds hidden patterns in human beings' collective excursions near, not-so-near, and far from home.  |
| In bubble-rafting snails, the eggs came first Posted: 11 Oct 2011 08:29 AM PDT It's "Waterworld" snail style: ocean-dwelling snails that spend most of their lives floating upside down, attached to rafts of mucus bubbles.  |
| Liquid can turn into solid under high electric field, physicists show in simulations Posted: 11 Oct 2011 08:29 AM PDT Physicists have demonstrated in simulations that under the influence of sufficiently high electric fields, liquid droplets of certain materials will undergo solidification, forming crystallites at temperature and pressure conditions that correspond to liquid droplets at field-free conditions.  |
| The strange rubbing boulders of the Atacama Posted: 11 Oct 2011 08:24 AM PDT A geologist's sharp eyes and upset stomach has led to the discovery, and almost too-close encounter, with an otherworldly geological process operating in a remote corner of northern Chile's Atacama Desert.  |
| Pendulums and floating film: Two seemingly unrelated phenomena share surprising link Posted: 11 Oct 2011 07:20 AM PDT A coupled line of swinging pendulums apparently has nothing in common with an elastic film that buckles and folds under compression while floating on a liquid, but scientists have discovered a deep connection between the two phenomena.  |
| Astrophysicists find evidence of black holes' destruction of stars Posted: 11 Oct 2011 07:20 AM PDT Astrophysicists have found evidence of black holes destroying stars, a long-sought phenomenon that provides a new window into general relativity. The research also opens up a method to search for the possible existence of a large population of presently undetectable "intermediate mass" black holes which are hypothesized to be precursors to the super-massive black holes at the centers of most large galaxies.  |
| Norwegian prawns to spice up Chinese noodles Posted: 11 Oct 2011 06:58 AM PDT Bioprospecting is opening up international markets for Norwegian seafood companies. Essences extracted from a prawn or octopus off the west coast of Norway could end up as flavoring in noodle packages in China.  |
