Understanding a nanomuscle

Dynamin as a nanomuscle. The filament coils around a membrane tube and, under GTP hydrolysis, forms active cross-bridges that collectively constrict the membrane. Researchers at Kanazawa University report in Proceedings of the National Academy of…

Deleting DNA to treat mitochondrial diseases

A multi-functional, small molecule can tag mutant genetic sequences inside mitochondria for removal. Mutant DNA sequences inside cellular mitochondria can be eliminated using a bespoke chemical compound. The approach, developed by scientists at Kyoto University’s…
