Gene Offers Clues to New Treatments for a Harmful Blood Clotting Disorder
Shown in blue is chromatin -- the condensed form of DNA that the cell remodels to form chromosomes. The PAD4 enzyme decondenses chromatin by loosening up the interaction between DNA and special proteins called histones. The histones modified by PAD4 are shown in fuchsia. This process helps to form both a bacteria-killing NET -- which is comprised of infection-combatting white blood cells called neutrophils -- and the fluffy, scattered ball that comprises a blood clot.

Autism Linked to Increased Genetic Change in Regions of Genome Instability
These microscopic images were taken as part of research to explore rearrangements of DNA in one of the hotspots of the human genome, where deletions and duplications occur at higher rates. Photo courtesy of Betsy Hirsch/University of Minnesota and Scott Selleck/Penn State University.
Crucial Step in Human DNA Replication Observed Using Fluorescent Tags
Stephen J. Benkovic, Mark Hedglin, and other members of Professor Benkovic's research team have studied the importance of “clamp loader” enzymes and their activities during DNA replication. In this image, the clamp loader is represented, for illustrative purposes, by a hand, which is loading the sliding clamp ring onto DNA. Credit: Benkovic lab, Penn State University
Penn State researching ways to improve computer speed, efficiency
Nitin Samarth, department head of physics at Penn State, works with the molecular beam epitaxy equipment in his lab. He conducts research to design and build new materials needed for radically new kinds of computer chips that could open the door to a new era of super-fast quantum computers.
