For years, cholesterol was thought to only be in the outer membrane of nicotinic acetylcholine receptors -- receptor polypeptides that respond to the neurotransmitter acetylcholine. Simulations conducted at the National Center for Supercomputing Applications demonstrated the possibility that cholesterol -- colored yellow, orange and red in this graphic -- may actually bind to sites within the protein's transmembrane domain.

A team of researchers at the NSF-supported EduceLab are working to revolutionize digital restoration. They’re investigating the Herculaneum Scrolls, ancient writings that were carbonized in the eruption of Mount Vesuvius in 79 A.D. In this episode of NSF’s “The Discovery Files” podcast, we are joined by EduceLab principal investigator Brent Seales, a computer science professor at the University of Kentucky, to hear about imaging the fragile scrolls, using advanced computer technology to process the data, and how the “Vesuvius challenge” is revealing words.
