A protein that plays an important role in embryonic development and nervous system wiring in humans appears to have been borrowed from bacteria. In a new study, scientists from the UChicago and Stanford describe the three-dimensional structure of proteins called teneurins for the first time.
A new study that concentrates on microbes in the upper gastrointestinal tract shows how the typical calorie-dense western diet can induce expansion of microbes that promote the digestion and absorption of high-fat foods. Over time, the steady presence of these microbes can lead to over-nutrition and obesity.
Researchers have developed a way to use light-sensitive nanowires made of microscopic snippets of silicon and gold to control the activity of neurons.
