Nanoscale velcro used for molecule transport

Biological membranes are like a guarded border. They separate the cell from the environment and at the same time control the import and export of molecules. The nuclear membrane can be crossed via many tiny pores. Scientists ...

Biologists uncover mechanisms for cholera toxin's deadly effects

Biologists at the University of California, San Diego have identified an underlying biochemical mechanism that helps make cholera toxin so deadly, often resulting in life-threating diarrhea that causes people to lose as much ...

Gold squeezed into micro-Velcro

Researchers at Ruhr University have used self-assembling techniques to produce gold microwires that have suitable properties for micro-Velcro. The research is published today in Science and Technology of Advanced Materials.

NASA showcases ‘spinoff’ technologies

Contrary to popular belief, Tang, Velcro and Teflon (along with the zero-gravity “space” pen) aren’t derived from NASA technology. NASA has, however, developed numerous technologies over the years, which are ...

UV light controls antibodies, improves biosensors

From detecting pathogens in blood samples to the study of protein synthesis, Quartz Crystal Microbalance (QCM) sensors have many uses in modern biology. In this technique, antibodies anchored to gold electrodes on a piece ...
