Minimally Invasive Nanotweezers For Single-cell Biopsies

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 […]

Monitoring Electromagnetic Signals In The Brain With MRI

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 […]

Silicon Probe Records Neural Activity Across Multiple Brain Regions

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 […]

Device Extracts Neurochemical Data From Cerebral Fluid

A novel device and analysis method that let doctors measure the neurochemicals in a patient’s brain has been developed by researchers at Ecole Polytechnique Federale de Lausanne (EPFL). The system involves collecting microdroplets of cerebral fluid and analyzing them to obtain chemical data that can help doctors diagnose and treat neurodegenerative diseases. Neurologists often use […]
