Detailed imaging of key receptors suggests new avenue for repairing brain function
For the first time, scientists using cryo-electron microscopy have discovered the structure and shape of key receptors connecting neurons in the brain's cerebellum, which is located behind the brainstem and plays a critical role in functions such as coordinating movement, balance and cognition.

Researchers from Tokyo Metropolitan University have created a new way of telling aged human cells apart from younger ones using electric fields. While key markers have been found for these senescent cells, current methods require biochemical labels which are difficult to apply and affect the cells themselves, making them difficult to study. The new method is label-free and less damaging. The team aims to diversify the method, extending it to other cell types.
