Newly discovered cell machinery breaks down protein aggregates into smaller pieces before 'taking it to the trash'

A new study from Aarhus University shows that our cells' ability to clean out old protein clumps, known as aggregates, also includes a—up till now unknown—partnership with an engine that breaks down bigger pieces into ...

The Hofstadter butterfly: Twisted bilayer graphene reveals two distinct strongly interacting topological phases

Magic-angle twisted bilayer graphene (MATBG) is a material created by stacking two sheets of graphene onto each other, with a small twist angle of about 1.1°. At this "magic angle," electrons move very slowly, which can ...
