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

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
