New approach is a promising first step toward the development of tiny devices that harvest electrical energy from everyday tasks

Imagine charging your phone as you walk, thanks to a paper-thin generator embedded in the sole of your shoe. This futuristic scenario is now a little closer to reality. Scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a way to generate power using harmless viruses that convert mechanical energy into electricity.

The scientists tested their approach by creating a generator that produces enough current to operate a small liquid-crystal display. It works by tapping a finger on a postage stamp-sized electrode coated with specially engineered viruses. The viruses convert the force of the tap into an electric charge. (more…)

Microbe That Can Handle Ionic Liquids

New Find From Joint BioEnergy Institute Could Help Reduce Biofuel Production Costs

In the search for technology by which economically competitive biofuels can be produced from cellulosic biomass, the combination of sugar-fermenting microbes and ionic liquid solvents looks to be a winner save for one major problem: the ionic liquids used to make cellulosic biomass more digestible for microbes can also be toxic to them. A solution to this conundrum, however, may be in the offing.

Researchers with the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI), a multi-institutional partnership led by Berkeley Lab, have identified a tropical rainforest microbe that can endure relatively high concentrations of an ionic liquid used to dissolve cellulosic biomass. The researchers have also determined how the microbe is able to do this, a discovery that holds broad implications beyond the production of advanced biofuels. (more…)

The ‘New’ Bing: Transforming Search from Finding to Doing

Bing’s new user experience surfaces the best from the Web, friends and experts to help people do more.

REDMOND, Wash. – May 10, 2012 – Microsoft today unveiled a major update to its Bing search engine that fundamentally transforms the way users search the Web. The update, the most significant since Microsoft launched Bing three years ago, is designed to help users act quickly by taking advantage of the Web’s evolving fabric.

With the new version of Bing, rolling out over the coming weeks and broadly available in the U.S. in early June, people can easily get advice and recommendations from friends and experts with the new social sidebar. They can also view useful, action-oriented information via the new snapshot feature. And they can find what they’re looking for faster, with more relevant results and a refreshed user interface. All of this is presented in a new, three-column design that focuses on helping users take the leap from finding information to making quick, informed decisions. (more…)

When Cells Hit the Wall: UCLA Engineers Put The Squeeze on Cells to Diagnose Disease

If you throw a rubber balloon filled with water against a wall, it will spread out and deform on impact, while the same balloon filled with honey, which is more viscous, will deform much less. If the balloon’s elastic rubber was stiffer, an even smaller change in shape would be observed.

By simply analyzing how much a balloon changes shape upon hitting a wall, you can uncover information about its physical properties.

Although cells are not simple sacks of fluid, they also contain viscous and elastic properties related to the membranes that surround them; their internal structural elements, such as organelles; and the packed DNA arrangement in their nuclei. Because variations in these properties can provide information about cells’ state of activity and can be indicative of diseases such as cancer, they are important to measure. (more…)

From Soil Microbe to Super-Efficient Biofuel Factory?

Berkeley Lab-led team explores a way to create biofuels, minus the photosynthesis

Is there a new path to biofuels hiding in a handful of dirt? Lawrence Berkeley National Laboratory (Berkeley Lab) biologist Steve Singer leads a group that wants to find out. They’re exploring whether a common soil bacterium can be engineered to produce liquid transportation fuels much more efficiently than the ways in which advanced biofuels are made today.

The scientists are working with a bacterium called Ralstonia eutropha. It naturally uses hydrogen as an energy source to convert CO₂ into various organic compounds. (more…)

New Graphene-Based Material Could Revolutionise Electronics Industry

The most transparent, lightweight and flexible material ever for conducting electricity has been invented by a team from the University of Exeter.

Called GraphExeter, the material could revolutionise the creation of wearable electronic devices, such as clothing containing computers, phones and MP3 players.

GraphExeter could also be used for the creation of ‘smart’ mirrors or windows, with computerised interactive features. Since this material is also transparent over a wide light spectrum, it could enhance by more than 30% the efficiency of solar panels.

Adapted from graphene, GraphExeter is much more flexible than indium tin oxide (ITO), the main conductive material currently used in electronics. ITO is becoming increasingly expensive and is a finite resource, expected to run out in 2017. (more…)

My Fair Physicist? Feminine Math, Science Role Models Do Not Motivate Girls

ANN ARBOR, Mich.— Women who excel in male-dominated science, technology, engineering and mathematic fields are often unjustly stereotyped as unfeminine.

However, if women are perceived as having feminine qualities, their success may actually decrease interest in these fields (usually referred to as “STEM”), particularly among young girls, according to a new University of Michigan study. (more…)
