(PhysOrg.com) -- Just like our roads, there is a lot of traffic within the cells in our bodies, because cell components, messenger molecules, and enzymes must also be brought to the right places in the cell. One of these transportation systems functions like a kind of railway: a system of molecular tracks is used to transport vesicles and their contents to their target destinations. http://www.physorg.com/news180602012.html Chemistry Mon, 21 Dec 2009 07:14:11 EST news180602012 Frederic Scheer is biding his time, convinced that by 2013 the price of oil will be so high that his bio-plastics, made from vegetables and plants, will be highly marketable. http://www.physorg.com/news180594717.html Chemistry Mon, 21 Dec 2009 05:17:07 EST news180594717 South Korea's LG Display said Monday it has developed the world's thinnest LCD television panel, measuring 2.6 millimetres (0.1 inches). http://www.physorg.com/news180594591.html Electronics Mon, 21 Dec 2009 05:10:54 EST news180594591 (AP) -- The Philippines' Mayon volcano turned up the heat with lava fountains and loud rumbling sounds Monday, and officials said it was getting closer to a major eruption that could come at any time. http://www.physorg.com/news180594352.html Space & Earth Mon, 21 Dec 2009 05:06:42 EST news180594352 The Egyptians supposedly used it to guide the construction the Pyramids.

On the macroscale, perhaps the closest analogy might be the sport of logrolling, in which two competitors try to balance on a log the longest while the log rolls on water. However, while the macro log rolls due to the competitors walking on it, the nanorod would roll by becoming electrically polarized by a beam of light. http://www.physorg.com/news180352909.html Nanotechnology Fri, 18 Dec 2009 10:40:01 EST news180352909 "T-rays" may make X-rays obsolete as a means of detecting bombs on terrorists or illegal drugs on traffickers, among other uses, contends a Texas A&M physicist who is helping lay the theoretical groundwork to make the concept a reality. In addition to being more revealing than X-rays in some situations, T-rays do not have the cumulative possible harmful effects. http://www.physorg.com/news180352656.html Physics Fri, 18 Dec 2009 10:30:01 EST news180352656
