PHILADELPHIA — A protein’s function depends on both the chains of molecules it is made of and the way those chains are folded. And while figuring out the former is relatively easy, the latter represents a huge challenge with serious implications because many diseases are the result of misfolded proteins. Now, a team of chemists at the University of Pennsylvania has devised a way to watch proteins fold in “real-time,” which could lead to a better understanding of protein folding and misfolding in general.
PHILADELPHIA -- Researchers at the University of Pennsylvania’s Perelman School of Medicine are suggesting that a prophylactic treatment option increasingly offered to breast cancer patients has only a slight benefit, and the modest gains to life expectancy the treatment provides may actually be offset by decreases in quality of life for many patients.
PHILADELPHIA — The American Physical Society has elected five University of Pennsylvania faculty members to its 2011 APS Fellowship class. They are Mark Devlin, Alan “Charlie” Johnson, Joshua Klein, Feng Gai and Howard Hu.
Devlin, Johnson and Klein are members of the School of Arts and Science’s Department of Physics and Astronomy.
PHILADELPHIA — Long the bane of picky eaters everywhere, broccoli’s taste is not just a matter of having a cultured palate; some people can easily taste a bitter compound in the vegetable that others have difficulty detecting. Now a team of Penn researchers has helped uncover the evolutionary history of one of the genes responsible for this trait. Beyond showing the ancient origins of the gene, the researchers discovered something unexpected: something other than taste must have driven its evolution.
PHILADELPHIA — Earthquakes are some of the most daunting natural disasters that scientists try to analyze. Though the earth’s major fault lines are well known, there is little scientists can do to predict when an earthquake will occur or how strong it will be. And, though earthquakes involve millions of tons of rock, a team of University of Pennsylvania and Brown University researchers has helped discover an aspect of friction on the nanoscale that may lead to a better understanding of the disasters.
PHILADELPHIA — Vision is amazing because it seems so mundane. Peoples’ eyes, nerves and brains translate light into electrochemical signals and then into an experience of the world around them. A close look at the physics of just the first part of this process shows that even seemingly simple tasks, like keeping a stable perception of an object’s color in different lighting conditions or distinguishing black and white objects, is, in fact, very challenging.
