(PhysOrg.com) -- Brookhaven scientists have created a new enzyme with the potential to interfere with a key cell-wall component in plants, possibly leading to plants that are easier to "digest" and convert to biofuels. http://www.physorg.com/news180624203.html Chemistry Mon, 21 Dec 2009 13:24:01 EST news180624203 (PhysOrg.com) -- Scientists at the U.S. Department of Energy`s Brookhaven National Laboratory have found a new way to use a synthetic form of DNA to control the assembly of nanoparticles - this time resulting in switchable, three-dimensional and small-cluster structures that might be useful, for example, as biosensors, in solar cells, and as new materials for data storage. The work is described in Nature Nanotechnology, published online December 20, 2009. http://www.physorg.com/news180624054.html Nanotechnology Mon, 21 Dec 2009 13:21:26 EST news180624054 (PhysOrg.com) -- By implanting an electrode into the brain of a person with locked-in syndrome, scientists have demonstrated how to wirelessly transmit neural signals to a speech synthesizer. The "thought-to-speech" process takes about 50 milliseconds - the same amount of time for a non-paralyzed, neurologically intact person to speak their thoughts. The study marks the first successful demonstration of a permanently installed, wireless implant for real-time control of an external device. http://www.physorg.com/news180620740.html Medicine & Health Mon, 21 Dec 2009 12:26:19 EST news180620740 Google Inc.'s reported plans to acquire local-listings service Yelp may face difficulties, with regulators attuned to the Mountain View, Calif.-based company's established dominance of the Internet-search and advertising markets, observers say. http://www.physorg.com/news180606013.html Technology Mon, 21 Dec 2009 08:21:03 EST news180606013 (PhysOrg.com) -- "The W boson is one of the very few major building blocks of matter," Dmitri Denisov tells PhysOrg.com. "It is a member of a family of particles that is the most fundamental in nature. The W boson is responsible for weak interactions, which govern some of the most important processes in nature." http://www.physorg.com/news180605589.html Physics Mon, 21 Dec 2009 08:13:57 EST news180605589 An unusual bowstring truss iron bridge that carried traffic across Roaring Run in Bedford County, Va. for almost 100 years is now a picturesque footbridge at the I-81 Ironto, Va. rest stop. Built in 1878, it is the oldest standing metal bridge in Virginia. In early December, a Virginia Tech undergraduate conducted a load-bearing analysis of the structure. http://www.physorg.com/news180604484.html Technology Mon, 21 Dec 2009 07:55:58 EST news180604484 (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) -- Philippine troops on Monday pressed the last 3,000 villagers who have refused to heed government warnings to leave the danger zone around a volcano that experts say is ready to erupt. 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.
