Recombinant spider silk proteins for applications in biomaterials

In materials science, spider silk is considered one of the most fascinating products of nature. The protein molecules, from which spider silk is made up of, can nowadays be biotechnologically produced with the help of genetically altered organisms. Possible applications of these biotechnologically produced proteins are the research focus of Prof. Dr. Thomas Scheibel, chairholder for biomaterials at the University of Bayreuth.

Robotic arm's big flaw: Patients say it's 'too easy'

One touch directs a robotic arm to grab objects in a new computer program designed to give people in wheelchairs more independence. University of Central Florida researchers thought the ease of the using the program's automatic mode would be a huge hit. But they were wrong - many participants in a pilot study didn't like it because it was 'too easy'.

nanoLAMPS created for use as molecular probes

Rohit Bhargava of the University of Illinois has come up with an intriguing new class of molecular probes for biomedical research called nanoLAMPs. Unlike most probes used in biomedicine or other types of research they don't require dyes or fluorescence but, like an ordinary house lamp, they do need a light switch in order to illuminate the molecular world.

Electricity collected from the air could become the newest alternative energy source

Imagine devices that capture electricity from the air - much like solar cells capture sunlight - and using them to light a house or recharge an electric car. Imagine using similar panels on the rooftops of buildings to prevent lightning before it forms. Strange as it may sound, scientists already are in the early stages of developing such devices.

AFM studies reveal path to protein crystallization in cell-like environments

Scientists at the Molecular Foundry, a nanoscience user facility at Berkeley Lab, have used atomic force microscopy to image in real time how S-layer proteins form crystals in a cell-like environment. This direct observation of protein assembly could provide researchers with insight into how microorganisms stave off antibiotics or lock carbon dioxide into minerals.
