Assistant Professor of Physics and Astronomy Cullen Blake discusses the Pluto flyby and "Earth's twin."Abigail Meisel
In July, NASA’s New Horizons space probe captured dazzling images of the dwarf planet Pluto and its moons during a 31,000-mile-per-hour flyby. Surprising even some experts, the pictures revealed a vast variety of geologic features from frozen plains to streams. In the scientific community these photographs are provoking as many questions as they are answering.
Dee Luo, C'16, pushes the limits of personalized medicine.Blake Cole, with Dee Luo
Each summer, Penn Arts and Sciences students pursue internships that often pave the way to their future career. To provide a unique perspective, we invited Dee Luo, a senior majoring in the Biological Basis of Behavior Program and minoring in Healthcare Management, to share her experience.
Patricia M. Williams Term Professor in Biology Junhyong Kim navigates the complex computations of single-cell genomics.Blake Cole
While most scientists spend their time trying to accumulate as much data as possible, Junhyong Kim has the opposite problem—too much data to manage.
Penn undergraduate named 2015 Society of Chemical Industry Scholar.Rebecca Guenard
This summer Alan Dai, a junior in the Vagelos Integrated Program in Energy Research (VIPER) will scale up his research experience to the industrial level. As the recently named Dupont Society of Chemical Industry Scholar, Dai will spend ten weeks at Dupont in Newark, Delaware learning to improve the manufacturing process of agricultural materials.
Associate Professor of Physics and Astronomy Masao Sako takes us way back.Blake Cole
Next time you take a sip from your water bottle, you might want to consider the fact that you are ingesting 14-billion-year-old molecules. It’s just one revelation from Associate Professor of Physics and Astronomy Masao Sako’s 60-Second Lecture Series entry The Origin of the Elements.
Chemistry students Keith Keenan, C’15, and Lily Owei, C’16, push the boundaries of undergraduate research.Blake Cole
College undergraduates Lily Owei and Keith Keenan don’t have a whole lot in common when it comes to their backgrounds. She was born in Nigeria, where she lived for seven years before moving to Germany, then South Africa, and finally to the U.S. to attend Penn. He grew up in China, where his mother and father taught English and homeschooled him.
RRL Professor of Psychology David Brainard examines the intricacies of color vision.Blake Cole
Next time someone asks you what your favorite color is, you might want to think twice before answering—your brain might be playing a trick on you. What we see when we look at an object is not its “true” physical color, says David Brainard, RRL Professor of Psychology, but our brain’s subjective reading of spectrum.
Professor of Physics and Astronomy Philip Nelson discusses the ins and outs of authoring a science textbook.Blake Cole
When Philip Nelson couldn't find a textbook that suited the needs of his biophysics class, he didn't take any shortcuts—he wrote one. "I didn’t feel that there was a book that really spoke to physics students about why this subject might be interesting to them,” he says. “There was a gap there.” Physical Models of Living Systems was the result.
Graduate student Beatrice Markiewicz is using novel techniques to disassemble the amyloid proteins responsible for diseases like Alzheimer’s.Dave Levitan
Alzheimer’s disease and other serious neurodegenerative disorders have been the subject of a tremendous research effort in recent decades. Much of the work, however, has gone into understanding the formation of the signature amyloid deposits—proteins that fold the wrong way.
Professor of Biology Ted Abel and Senior Research Associate Robbert Havekes examine how losing sleep affects memory.Dave Levitan
“There’s this view that sleep is for the weak,” says Ted Abel. “‘I’m getting ready for final exams, I’m just gonna stay up, I’ll be fine.’” Not so fast: New research from Abel’s lab has illuminated the specific molecular mechanism in mice of how sleep deprivation can sap the ability to remember things.
