Photos of New Comet Approaching a Very Close Encounter with Mars
his composite of Comet Sliding Spring (C/2013 A1) merges images taken between May 27 and May 29, 2014 with the Ultraviolet Optical telecsope (UVOT) on the NASA's Swift satellite. Sunlight reflected from the comet's dust, which produces most of the light in this image, appears yellow. Ultraviolet light produced by hydroxyl (OH), a molecular fragment of water, appears violet in this image. Credit: NASA/Swift/D. Bodewits (UMD), DSS.
Burst of Mutations During Initial Infection Allows Bacteria To Evade Human Immune Response
Electron micrograph of the stomach bacteria Helicobacter pylori. A research team including Penn State scientists has discovered that a burst of rapid evolution immediately following infection allows this bacteria that causes ulcers in humans to survive the immune system and establish a chronic infection.

Rescue of Alzheimer's Memory Deficit Achieved by Reducing 'Excessive Inhibition'
A new drug target to fight Alzheimer's disease has been discovered by a research team led by Gong Chen at Penn State University that also has potential for development as a novel diagnostic tool for Alzheimer's disease. This image shows a microscopic view of the high concentration (red) of gamma-aminobutyric acid (GABA) in the reactive astrocytes (green) in the human brain with Alzheimer's disease.

Until Death Do Us Part: Genetics Reveal that Threatened Reef Corals and Their Symbiotic Algae Live Together but Evolve Independently
Shallow reef waters were once dominated by extensive thickets of the Caribbean Elkhorn Coral, Acropora palmata, a species that is now endangered. This impressive stand, photographed in Curacao, provides habitat for numerous fish and invertebrate species. Credit: Iliana B. Baums, Penn State University.
