New approach for solving protein structures from tiny crystals

Using x-rays to reveal the atomic-scale 3-D structures of proteins has led to countless advances in understanding how these molecules work in bacteria, viruses, plants, and humans—and has guided the development of precision drugs to combat diseases such as cancer and AIDS. But many proteins can't be grown into crystals large enough for their atomic arrangements to be deciphered. To tackle this challenge, scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and colleagues at Columbia University have developed a new approach for solving protein structures from tiny crystals.

Researchers make soft, actuated objects using commercial knitting machines

Carnegie Mellon University researchers have used computationally controlled knitting machines to create plush toys and other knitted objects that are actuated by tendons. It's an approach they say might someday be used to cost-effectively make soft robots and wearable technologies.

No crime in Huawei 5G leak: British police

The top-secret leak that Britain had conditionally allowed China's Huawei to develop its 5G network, which brought down the defence minister, does not amount to a criminal offence, police concluded Saturday.
