Biologist Ted Abel discovers a way to reverse cognitive impairment caused by sleep deprivation.Priya Ratneshwar
The cognitive consequences of not getting enough sleep—such as compromised memory and attention—are well established, both anecdotally and scientifically. However, many of the biological mechanisms by which sleep deprivation affects brain function remain a mystery. A research collaboration led by Edmund J. and Louise W.
Undergraduate Tariro Mupombwa probes the mechanisms of energy production in tuberculosis bacteria.Priya Ratneshwar
Among the many cultural differences Tariro Mupombwa, C’10, experienced when she first came to Penn from Zimbabwe was that of classroom expectations. While it was an adjustment for the biochemistry major to address her professors by their first names, still more startling was the intensity of class participation.
Psychology majors conduct research on a tropical isle.Peter Nichols
Most undergraduate study means going to class, reading books, doing homework, writing papers, taking exams.
Graduate student Peter Yunker sheds light on the mystery of aging glass.Priya Ratneshwar
Glasses have been used for thousands of years, but some of the fundamental properties of these common household and industrial materials still remain unexplained. One such puzzle is why glasses become more viscous and rigid over time without major changes to their structure—a phenomenon known as aging. A new study conducted by physics doctoral student Peter Yunker, James M.
College student Sourav Bose works to improve emergency response care in Guatemala.Priya Ratneshwar
Sourav Bose, C’11, W’11, has been working with emergency medical services since he was in high school. He volunteered with the local ambulance corps in his suburban New Jersey hometown, and at Penn he is a member of the Medical Emergency Response Team, a student-run service organization that provides emergency medical services to the University community.
Psychologists Peter DeScioli and Robert Kurzban propose a new theory of human friendship.B. Davin Stengel
If you’ve ever designated your “top friends” on MySpace, Facebook or another social networking website, you may have done more than give a nod to your favorite people on that particular platform.
Biologist Peter Petraitis and team discover rapid increases in shell size in the Atlantic dogwhelk.Priya Ratneshwar
Nucella lapillus, the Atlantic dogwhelk, is one of the best known and most widely studied organisms in the North Atlantic Ocean. Yet until now, no one had noticed that over the past century shell lengths of these sea snails have increased in size by an average of 22.6 percent.
Physicist Andrea Liu discusses research into how systems of particles transition to jammed states.B. Davin Stengel
In collaboration with her colleagues in the physics department and researchers at the University of Chicago, Andrea Liu is trying to understand how certain systems of particles come to behave like solids when they jam.
Penn psychologists identify neural correlates of visual and verbal cognitive styles.B. Davin Stengel
In the lab of Class of 1965 Endowed Term Professor of Psychology Sharon Thompson-Schill, the range of topics being studied is fairly broad, but one overarching theme, she explains, is an attempt to better understand differences between people.
Cosmologist Mark Devlin uses balloon-borne telescope to find the source of half the light in the universe.Peter Nichols
Just before Christmas in 2006, Mark Devlin, the Reese W. Flower Professor of Astronomy and Astrophysics, led a team of scientists to launch a telescope that would scrutinize the heavens in search of primeval galaxies at the far reaches of the universe.
