Scientists 'watch' as individual alpha-synuclein proteins change shape

In an Early Edition publication of The Proceedings of the National Academy of Sciences (PNAS) this week, the researchers demonstrate the "alpha-synuclein dance" - the switching back and forth of the protein between a bent helix and an extended helix as the surface that it is binding to changes.

Spun-sugar filaments show potential for regenerating nerves

Researchers at Purdue University have developed a technique using spun-sugar filaments to create a scaffold of tiny synthetic tubes that might serve as conduits to regenerate nerves severed in accidents or blood vessels damaged by disease.

Nanoscale dots target and track apoptosis

Apoptosis, or programmed cell death, is a hallmark effect triggered by effective anticancer drugs. Now, researchers in Korea have developed a biocompatible, fluorescent nanoparticle that could provide an early sign that apoptosis is occurring as a result of anticancer therapy.

Better understanding of membrane fusion

Cells constantly swap cargo bound in vesicles, miniscule membrane-enclosed packages of proteins and other chemicals. Before the swap can take place, the vesicle membrane must fuse with another membrane, creating channels packages can pass through.
