Mimicking Biopolymers On A Molecular Scale: Nano(bio)technology Based On Engineered Proteins Proteins are ubiquitous biopolymers which adopt distinct three-dimensional structures and fulfil a multitude of elementary functions in organisms. Recent systematic studies in molecular biology and biotechnology have improved the understanding of basic functional and architectural principles of proteins, making them attractive candidates as concept generators for technological development in material science, in particular in biomedicine and nano(bio)technology. Medical News TodayA persistent spin state could revolutionize spintronics By controlling the collective spin state of highly mobile electrons in semiconductors, researchers in the Materials Sciences Division (MSD) at the U.S. Department of Energy's Lawrence Berkeley National Laboratory have taken a major step forward in the technology of spintronics. nanowerk.comASU Center for Nanotechnology in Society faculty receive new NSF grants Two Arizona State university faculty members - Erik Fisher, Ph.D., assistant research professor, Center for Nanotechnology in Society, and David H. Guston, Ph.D., director of CNS-ASU - have been awarded a three-year, $540,000 grant from the National Science Foundation. nanowerk.comStanford offers free podcast on iPhone app development Aspiring iPhone app developers can view a free Stanford computer science course detailing the technique, according to reports Thursday. (AAPL) Biz JournalHow Do We Support Today`s Einsteins? Is today's academic and corporate culture stifling science's risk-takers and stopping disruptive, revolutionary science from coming to the fore? A new article considers those who have shifted scientific paradigms and asks what we can do to make sure that those who have the potential to change our outlook on the world also have the opportunity to do so. Science dailyRobot scientist becomes first machine to discover new scientific knowledge [NEWS]Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have created a Robot Scientist which the researchers believe is the first machine to have independently discovered new scientific knowledge. The robot, called Adam, is a computer system that fully automates the scientific process. The work will be published tomorrow (03 April 2009) in the journal Science. Prof Ross King, who led the research at Aberystwyth university, said: “Ultimately we hope to have teams of huma… LifeSciencesWorld.com`Eureka machine` puts scientists in the shade The machine, which took only two hours to come up with Newton's laws of motion, marks a turning point in the way science is doneScientists have created a 'Eureka machine' that can work out the laws of nature by observing the world around it - a development that could dramatically speed up the discovery of new scientific truths.The machine took only hours to come up with the basic laws of motion, a task that occupied Sir Isaac Newton for years after he was inspired by an apple falling from a tree.Scientists at cornell university in New York have already pointed the machine at baffling problems in biology and plan to use it to tackle questions in cosmology and social behaviour.The work marks a turning point in the way science is done. Eureka moments, which supposedly began in Archimedes' bath more than 2,000 years ago, might soon be happening not in the minds of geniuses, but through the warm hum of electronic circuitry.'We've reached a point in science where there's a lot of data to dea GuardianSick power: viral batteries closer to energizing hybrid cars, cell phones Biology – you, me, and the tree – is all based on chemical energy, yet batteries for our electronic devices have mostly relied on non-lifelike arrangements such as lead-acid and nickel-cadmium hybrids to produce power. But that may soon change. Researchers at the Massachusetts Institute of Technology (M.I.T) report in Science today that they constructed a battery that uses biological matter – namely a virus dubbed M13 – as a key component. The virus essentially acts as a “biological scaffold,” the scientists write, to support elements of a lithium ion-type battery.

At the same time they have discovered a new conservation law, an important advance in fundamental physics. Physorg.com1 2 |

How does Feedzilla work?
Feedzilla is a news aggregator which categorizes news stories by topic. It is a platform where webmasters and bloggers can find an unmatched selection of easy to use, automatically updating and professional news widgets for their sites. Feedzilla supports the building of widgets in various formats, as well as allowing the addition of news widgets to different blogging platforms and social networks.
Feedzilla manually aggregates news summaries found in RSS feeds, and redistributes them in either RSS format or as a news widget. Content is collected 24 hours a day, 7 days a week from an ever-growing list of providers.
