Caught in the act: 3D structure of an RNA-modifying protein determined in action
Caught in the act: 3D structure of an RNA-modifying protein determined in action 21 April 2016The structure of a bacterial RNA-binding protein has been determined in the act of modifying a molecule of RNA -- an achievement that provides researchers with a unique view of the protein's function in action and could lead to clues that would help in the fight against the development of antibiotic-resistant infections. A paper describing the findings by a team of Penn State University researchers is published in the current issue of the journal Science.
Your viruses could reveal your travel history, and more
Your viruses could reveal your travel history, and more 01 April 2016The genomes of two distinct strains of the virus that causes the common lip cold sore, herpes simplex virus type 1 (HSV-1), have been identified within an individual person -- an achievement that could be useful to forensic scientists for tracing a person's travel history. The research also opens the door to understanding how a patient's viruses influence the course of disease. The research by an international team led by Moriah L. Szpara, assistant professor of biochemistry and molecular biology at Penn State University, will be published in the May 2016 issue of the journal Virology.
Record-breaking ultraviolet winds discovered near black hole
Record-breaking ultraviolet winds discovered near black hole 21 March 2016The fastest winds ever seen at ultraviolet wavelengths have been discovered near a supermassive black hole by a research team that includes a Penn State University astronomer. "This new ultrafast wind surprised us when it appeared at ultraviolet wavelengths, indicating it is racing away from the ravenous black hole at unprecedented speeds -- almost like a bat of out Hell," said William Nielsen (Niel) Brandt, the Verne M. Willaman Professor of Astronomy and Astrophysics and a professor of physics at Penn State, a member of the research team.
