NASA's Swift Satellite Marks 10 Years of Game-changing Astrophysics: Mission Control Is at Penn State
In the most common type of gamma-ray burst, illustrated here, a dying massive star forms a black hole (left), which drives a particle jet into space. Light across the spectrum arises from hot gas near the black hole, collisions within the jet, and through the jet's interaction with its surroundings. Image Credit: NASA's Goddard Space Flight Center

Battling drug-resistant pathogens: Biologist Andrew Read argues for new treatment strategies in race against rapidly evolving 'bugs.'
Postdoctoral researcher Eleanore Sternberg uses a bottle of warm water to attract female mosquitoes to a mesh barrier in Penn State's insectary so they can be separated from males. The insectary, completed in 2011 at a cost of $3 million, is one of the best in the country. Its environmental chambers allow scientists to do complex experiments involving temperature variations, insecticides, and behavioral assessments on a variety of insect species. Image: Patrick Mansell
Department of Astronomy and Astrophysics Installs New Telescope in Rooftop Observatory

First detailed picture of a cancer-related cell enzyme in action on a chromosome unit
This image is the first detailed picture of the crystal structure of a gene-regulation enzyme while it is working on a nucleosome -- a fundamental component of the chromosomes that provide structure and organization for an organism's genes. Credit: Song Tan lab, Penn State University

Greater Rates of Mitochondrial Mutations Discovered in Children Born to Older Mothers
The inner membrane of each mitochondrion contains distinctive folds known as cristae. In a normal mitochondrion (left) these folds fill the interior, but these folds are lost in damaged or dysfunctional mitochondria (right). Dozens of rare diseases have been shown to result from this type of mitochondrial dysfunction. Several others -- including Alzheimer disease, autism, cancer, cardiovascular disease, Parkinson disease, and type 2 diabetes -- are suspected to involve the mitochondria. Credit: Gary Carlson
