Grad student Amitai Bin-Nun explores light bending around black holes.Priya Ratneshwar
Mathematically, the black hole at the center of the Milky Way is deceptively simple. With four million solar masses of matter condensed into an infinitely small volume, this object is essentially a point with massive gravitational attraction.
Psychologist Joe Kable explores the neurological and psychological workings of choice.Mark Wolverton
You may not realize it, but you just made a decision: namely, to read (or at least start to read) this article. Why? What process just occurred in your brain to cause you to be reading this sentence right now? How and why did you make that decision at that moment?
Senior Rachel Romeo uses eye movements to study the impact of hearing impairments on infant language learning.Priya Ratneshwar
In taking American Sign Language to fulfill her foreign language requirement, Rachel Romeo, C'11, often interacted with the Philadelphia Deaf community. She came across several people who said they'd suffered ear infections or diseases like meningitis in early childhood, and as a result, had developed hearing impairments that had gone undetected.
SAS faculty share their insights on the human brain.Priya Ratneshwar
Everything from education to warfare comes down to the workings of the human mind, and now the mind itself is being understood in terms of the brain. Across numerous disciplines, Penn Arts and Sciences faculty are studying this amazing three-pound organ and the insights it is offering on diverse human problems.
Grad student identifies a new species of dinosaur.Mark Wolverton
"According to my parents, I've been interested in dinosaurs since I was a very young child," notes graduate student Andrew McDonald, "farther back than I can remember." By high school, he had decided to make a career out of studying them.
Mathematicians Phillip Gressman and Robert Strain solve a 140-year old equation describing the motion of gas molecules.Priya Ratneshwar
During the late 1860s and 1870s, when steam-powered technology was at its height, scientists were eager to understand the mechanisms underlying their empirical observations of how the temperature, volume and pressure of gaseous material interacted. In 1872, physicists Ludwig Boltzmann and James Clerk Maxwell developed a foundational equation predicting the motion of gas molecules.
Rising senior Michael Sulewski helps explore the molecular basis of long-term memory.Priya Ratneshwar
For the past two years Michael Sulewski, C'11, has worked with a team of scientists in the lab of biologist Ted Abel on cutting-edge research that explores how to increase gene activity central to long-term memory formation.
Douglas Jerolmack and Federico Falcini of the Department of Earth and Environmental Science discuss the catastrophic oil leak in the Gulf of Mexico.Peter Nichols
Assistant Professor of Earth and Environmental Science Douglas Jerolmack and postdoctoral researcher Federico Falcini have been studying the flow of river water and sediment into large bodies of the Earth's waters.
Graduate student Shermin de Silva studies Asian elephants in Sri Lanka.Priya Ratneshwar and Patrick Boehmcke
Biology graduate student April 2010
Psychologist Michael Kahana identifies a type of brain cell that senses direction.Mark Wolverton
Long before we had Global Positioning System gadgets to navigate through unfamiliar towns, humans had evolved their own natural ability to find their way and move through the world.
