    Cognition Without Control

    Neuroscientist Sharon Thompson-Schill shows that a little bit of frontal lobe goes a long way in learning.

    Teachers work hard to get and keep the attention of a classroom full of kids, and on the night shift, parents put lots of effort into keeping their flitting and impetuous brains on track with homework. Sometimes it can seem a wonder that kids learn anything at all.

    Green Label

    College sophomore Doug Miller develops proposal to help foster more sustainable consumption.

    Most of us would like to make more environmentally conscious choices as consumers, but the overwhelming amount of information about what makes a product "green" (or not) can range from confusing to contradictory to downright misleading.

    The Science of Sleep

    Biologist Ted Abel discovers a way to reverse cognitive impairment caused by sleep deprivation.

    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.

    Digging Deeper

    Undergraduate Tariro Mupombwa probes the mechanisms of energy production in tuberculosis bacteria.

    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.

    What I Did for Summer Vacation

    Psychology majors conduct research on a tropical isle.

    Most undergraduate study means going to class, reading books, doing homework, writing papers, taking exams.

    Taking a Closer Look at Glass

    Graduate student Peter Yunker sheds light on the mystery of aging glass.

    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.

    Improving the System

    College student Sourav Bose works to improve emergency response care in Guatemala.

    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.

    That's What Friends are For?

    Psychologists Peter DeScioli and Robert Kurzban propose a new theory of human friendship.

    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.

    Re-examining a Snail's Pace

    Biologist Peter Petraitis and team discover rapid increases in shell size in the Atlantic dogwhelk.

    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.

    Jam Session

    Physicist Andrea Liu discusses research into how systems of particles transition to jammed states.

    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.
