Welcome to the second day of the New Year! Like tasty sliders, these short news stories should get the juices flowing for big developments in 2020. Electric Proteins Dr. Stuart Lindsey at Arizona State University is an expert in single-molecule dynamics in biomolecules. Older methods of observing protein structure, such as X-ray crystallography, only gave single snapshots of the highly dynamic world, he says, where proteins rapidly change conformations and interact in complex ways. Electron transport has been well known in the cases of photosynthesis and metabolism. But a few years ago, his team was astonished to find that a run-of-the-mill protein conducted electricity. The protein was acting like a wire! Further observations revealed that all proteins conduct electricity — even the ones that had “weren’t designed to do this”—…
