An ultra-small, wireless, battery-free device uses light to record individual neurons so neuroscientists can see how the brain is working, researchers report. “As biomedical engineers, we are working with collaborators in neuroscience to improve tools to better understand the brain, specifically how these individual neurons, the building blocks of the brain, interact with each other… Read more

A wireless sensor so small clinicians can implant it in the blood vessels of the brain could help evaluate healing of aneurysms. Aneurysms are bulges that can cause death or serious injury if they burst. The stretchable sensor, which operates without batteries, would wrap around stents or diverters implanted to control blood flow in vessels… Read more

A new technique enables researchers to extract single molecules from live cells, without destroying them. The research, developed by a team led by Professor Joshua Edel and Dr. Alex Ivanov at Imperial College London, could help scientists in building up a human cell atlas, providing new insights into how healthy cells function and what goes… Read more

Researchers commonly study brain function by monitoring two types of electromagnetism — electric fields and light. However, most methods for measuring these phenomena in the brain are very invasive. MIT engineers have now devised a new technique to detect either electrical activity or optical signals in the brain using a minimally invasive sensor for magnetic… Read more

A new technology for monitoring neural activity allows scientists to simultaneously follow the nervous system’s cellular conversations at hundreds of different sites within the brain. The new probes are expected to give scientists a much clearer picture of how different parts of the brain work together to process information. The $5.5 million collaboration led by… Read more
