Human brain diseases, such as Parkinson’s disease, involve damage in more than one region of the brain, requiring technology that could precisely and flexibly address all affected regions simultaneously. Researchers at Washington University in St. Louis have developed a noninvasive technology combining a holographic acoustic device with genetic engineering that allows them to precisely target […]

Fast ‘yes’ better for brain than slow ‘no’
Mechanical engineers find brain’s vulnerability to head motion depends on direction and frequency, not just impact strength
NIH funds study of ultrasound with genetics to treat brain disorders
Researchers have developed methods to study and manipulate areas of the brain, though many of those methods are restricted by the limited depth that light can reach within the brain. A multidisciplinary team at Washington University in St. Louis plans to overcome that limitation by integrating ultrasound with genetics to precisely modify neurons in the […]
Air monitor can detect COVID-19 virus variants in about 5 minutes
Now that the emergency phase of the COVID-19 pandemic has ended, scientists are looking at ways to surveil indoor environments in real time for viruses. By combining recent advances in aerosol sampling technology and an ultrasensitive biosensing technique, researchers at Washington University in St. Louis have created a real-time monitor that can detect any of […]
Pappu to explore ways in which charge contributes to diverse states of proteins
Intrinsically disordered proteins (IDPs) are defined by structural diversity, and the determinants of this diversity are an important area of biophysical investigation. IDPs are involved in a range of important biological processes, including cell signaling and regulation, that allow healthy cells to respond to environmental factors appropriately, but they are also associated with human diseases […]

Study into potassium channels reveals novel mechanism behind epilepsy, drug modulation
Epilepsy is a neurological disorder that arises from abnormal electrical activity in the brain leading to seizures. These seizure events can have a variety of causes, including genetic variants in a family of proteins that regulate potassium ions in the brain. Researchers at Washington University in St. Louis have led an international team to take […]
