New Group Of Algae Discovered: Picobiliphytes An international group of researchers has succeeded in identifying a previously unknown group of algae. As currently reported in the scientific journal Science, the newly discovered algae are found among the smallest members of photosynthetic plankton -- the picoplankton. On account of the minute size of the organisms and the appearance of phycobili-proteins, researchers have termed the new group "Picobiliphyta." Ganymede Makes Big Impression On Jupiter's Auroral Lightshows Studies of features in Jupiter’s spectacular and rapidly changing aurorae have given new insights into the complex electromagnetic interactions between the giant planet and two of its innermost moons. As Ganymede and Io orbit Jupiter, they interact with regions of plasma and generate electromagnetic waves that are projected along Jupiter’s magnetic field lines towards Jupiter’s poles where they cause auroral bright spots. Scientists from the University of Liège in Belgium have used thousands of images taken by the Hubble Space Telescope in ultraviolet wavelengths to monitor these auroral features in unprecedented detail. Device Makes Objects Invisible In Certain Light Conditions Scientists have designed a device, called a dc metamaterial, which makes objects invisible under certain light – very low frequency electromagnetic waves - by making the inside of the magnetic field zero but not altering the exterior field. The device, which up to date has only been studied in theoretical works, thus acts as an invisibility cloak, making the object completely undetectable to these waves. Tryptophan No Turkey In Boosting Immune System, Stanford Study Shows Tryptophan is the source of Thanksgiving legend and grist for a "Seinfeld"episode, but it's not the chemical that you'd expect to find in Lawrence Steinman's lab. [Ironic] Professional beggars prowling about the streets of Moroccan c The government plans to crack down on the scam used by faux beggars in growing numbers for a kind of "emotional blackmail", a cabinet minister was quoted as saying... Pulse Pressure Identified As Important Risk Factor For Atrial Fibrilla Increased pulse pressure (the difference between systolic and diastolic blood pressure) appears to be an important predictor of the risk for new onset atrial fibrillation, according to a study in the February 21 issue of JAMA. X-ray Oscillations From Biggest Star Quake Provide Clues To Mysterious A gigantic explosion on a neutron star halfway across the Milky Way galaxy, the largest such explosion ever recorded in the universe, should allow astronomers for the first time to probe the interiors of these mysterious stellar objects. Multidetector CT Accurately Locates Bowel Perforation Avoiding Need Fo Multidetector CT (MDCT) without the use of contrast media can show the precise site of a bowel perforation, avoiding the need for surgeons to do exploratory surgery of the patient's gastrointestinal tract to locate the problem, a new study shows. Building A Complete Metabolic Model: Comprehensive Understanding Of Ba Researchers have constructed a complete model, including 3-D protein structures, of the central metabolic network of the bacterium Thermotoga maritima (T. maritima). Bladder cancer risks increase over time for smokers Risk of bladder cancer for smokers has increased since the mid-1990s, with a risk progressively increasing to a level five times higher among current smokers in New Hampshire than that among nonsmokers in 2001-2004, according to a new study.
