Chemists reveal how tau proteins form tangles

One of the hallmarks of Alzheimer's disease is the presence of neurofibrillary tangles in the brain. These tangles, made of tau proteins, impair neurons' ability to function normally and can cause the cells to die.

Tracking chirality in real time

Chiral molecules exist in two forms, called enantiomers, which are mirror images of each other and non-superimposable—much like a pair of hands. While they share most chemical and physical properties, enantiomers can have ...
