Programming Cells, With CellOS 58

First time accepted submitter JoeMerchant writes "An international team of synthetic biologists, led by professor of computer science Natalio Krasnogor at the University of Nottingham, hopes to revolutionize synthetic biology with what they call CellOS, a 'bottom-up approach to cellular computing, in which computational chemical processes are encapsulated within liposomes.' The bold project is aptly named AUdACiOuS."

Start-Up Genetically Modifies a Better Biofuel Bug 124

Al writes "A tiny cellulose-eating bacterium found a few years ago in the Chesapeake Bay has been genetically modified to help it break down cellulose and convert the results into the sugars needed to make ethanol. Scientists analyzed the organism's genome in 2003 and found that it possessed a combination of enzymes that simultaneously break down the tough cell walls in dead plants and convert the remaining cellulose into sugars. Recently, Zymetis completed its first successful commercial-scale trial using the bug. The company ran the modified microbe through a series of tests in large fermenters and found that it could convert one ton of cellulosic plant fiber into sugar in 72 hours. The microbe's main advantage is its ability to naturally combine two major steps in the ethanol process, which the company says could considerably slash the high costs of producing ethanol from cellulosic biomass like switchgrass, wood chips, and paper pulp. The piece includes a video of the company's CEO discussing the project."

YouTube Coming To the PS3 and Wii 87

Clara writes "The YouTube blog has announced that YouTube is on its way to the PlayStation 3 and Wii. From the article: 'Have you ever wanted to just sit on your couch and watch YouTube on your TV? Well, now that's possible via YouTube for Television, initially available through the Sony PS3 and Nintendo Wii game consoles at www.youtube.com/tv. Currently in beta, the TV Website offers a dynamic, lean-back, 10-foot television viewing experience.' No YouTube for Xbox, however (Google must simply not have gotten around to Microsoft yet)."

Bandwidth Use In MMOs 188

Massively is running a story about bandwidth costs for MMOs and other virtual worlds. It's based on a post at the BBC on the same subject which references a traffic analysis (PDF) done for World of Warcraft. Quoting: "If you're an average user on capped access, the odds are you have roughly 20Gbytes per month to allocate among all of your Internet usage (it varies depending on just where you are). For you, sucking back (for example) a 2GB World of Warcraft patch isn't something you can just do. It's something you have to plan for — and quite often you have to plan for in the following month. Even a 500MB download has to be handled with caution. MMOGs as a rule don't use a whole lot of bandwidth in actual operation. However, the quantity definitely rises in busy areas with lots of players, where there are large numbers of mobs, or on raids, and takes quite a much larger jump if you're using voice as well."

Adult Brains More Flexible Than Previously Thought 123

stemceller passed us a link to the official site for Johns Hopkins, which is reporting on some research into cognition. Generally, doctors have understood our best learning to be done at a young age, when the brain has a 'robust flexibility'. As we get older, our brain cells become 'hard-wired' along certain paths and don't move much - if at all. Or, at least, that was the understanding. Research headed by the hospital's Dr. Linden has taken advantage of 'two-photon microscopy', a new technique, to get a new picture inside a mouse's head. "They examined neurons that extend fibers (called axons) to send signals to a brain region called the cerebellum, which helps coordinate movements and sensory information. Like a growing tree, these axons have a primary trunk that runs upward and several smaller branches that sprout out to the sides. But while the main trunk was firmly connected to other target neurons in the cerebellum, stationary as adult axons are generally thought to be, 'the side branches swayed like kite tails in the wind,' says Linden. Over the course of a few hours, individual side branches would elongate, retract and morph in a highly dynamic fashion. These side branches also failed to make conventional connections, or synapses, with adjacent neurons. Furthermore, when a drug was given that produced strong electrical currents in the axons, the motion of the side branches stalled.'"

Interstellar Dust Could Be "Alive" 332

reezle writes "An international team has discovered that, under the right conditions, particles of inorganic dust can become organized into helical structures. These structures can interact with one another in ways that are usually associated with organic compounds and with life. Not only do these helical strands interact in a counterintuitive way in which like can attract like, but they also undergo changes that are normally associated with biological molecules, such as DNA and proteins, say the researchers. For example, they can divide to form two copies of the original structure. These new structures can also interact to induce changes in their neighbors. And they can even evolve into yet more structures as less stable ones break down, leaving behind only the fittest structures in the plasma. 'These complex, self-organized plasma structures exhibit all the necessary properties to qualify them as candidates for inorganic living matter,' said the lead researcher. 'They are autonomous, they reproduce and they evolve.'" The research, published in the New Journal of Physics, was carried out using a computer model of molecular dynamics.

LG Phillips Patents Oil and Water Display 90

jordanhh writes "Tech.co.uk reports that LG Phillips has filed a patent for a new type of thin, flexible display. 'The pixels are made from tiny plastic cells filled with minute amounts of oil and water. The oil floats on the surface of the water and shrouds the colored surface underneath it. When electricity is applied across the cell, the oil moves aside, changing the color of the pixel.'"
