Engineering team develops self-powered mobile polymers

One of the impediments to developing miniaturized, "squishy" robots is the need for an internal power source that overcomes the power-to-weight ratio for efficient movement. An international group involving Inha University, ...

Team finds Southern East Africa getting wetter, not dryer

The prevailing notion that the African continent has been getting progressively drier over time is being challenged by a new study that finds that drought has actually decreased over the past 1.3 million years and that the ...

Seeing silicon crystal transform to amorphous

A team of researchers led by the University of Pittsburgh's Scott X. Mao has observed at atomic scale a previously unknown mechanism of shear-driven crystal to amorphously transform in silicon. The paper "In situ observation ...

Researchers develop a small-molecule switch to activate proteins

From growing teeth, bones, and tissue in skin and organs to creating enzymes and hormones, proteins are one of the most diverse and important elements of living organisms. But those varied purposes, along with the interconnectivity ...
