Helicopter could be 'scout' for Mars rovers Posted: 26 Jan 2015 07:51 AM PST Getting around on Mars is tricky business. Each NASA rover has delivered a wealth of information about the history and composition of the Red Planet, but a rover's vision is limited by the view of onboard cameras, and images from spacecraft orbiting Mars are the only other clues to where to drive it. To have a better sense of where to go and what's worth studying on Mars, it could be useful to have a low-flying scout.

Researchers make magnetic graphene Posted: 26 Jan 2015 06:59 AM PST Graphene has many desirable properties. Magnetism alas is not one of them. Magnetism can be induced in graphene by doping it with magnetic impurities, but this tends to disrupt graphene's electronic properties. Now physicists have found a way to induce magnetism in graphene while also preserving graphene's electronic properties. They have accomplished this by bringing a graphene sheet very close to a magnetic insulator -- an electrical insulator with magnetic properties.

Visualizing interacting electrons in a molecule Posted: 26 Jan 2015 06:59 AM PST Scientists have succeeded in directly imaging how electrons interact within a single molecule. Understanding this kind of electronic effects in organic molecules is crucial for their use in optoelectronic applications, for example in organic light-emitting diodes, organic field-effect transistors and solar cells.

Chemists find a way to unboil egg whites: Ability to quickly restore molecular proteins could slash biotechnology costs Posted: 26 Jan 2015 06:59 AM PST Chemists have figured out how to unboil egg whites -- an innovation that could dramatically reduce costs for cancer treatments, food production and other segments of the $160 billion global biotechnology industry, according to new findings.

New programming language for fast simulations Posted: 26 Jan 2015 05:39 AM PST Programming is a time-consuming process, and it may take many years to develop even a basic simulator. Researchers want to simplify this process. They have created a language similar to the language of mathematics. This allows them to subdivide the work process in such a way that reduces the time it takes to develop a simulator. A mathematician can then focus on what he or she knows best -- the simulator's area of application. Programming experts, on the other hand, can sit and work with "the translator" in order that the translated code can run faster, and they don't have to worry about the application.
