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.
Graduate student Annalise Paaby studies how natural selection affects lifespan in fruit flies.Priya Ratneshwar
Scientists have long known that genes play an important role in lifespan and longevity, and they have made significant progress in understanding the complex genetic mechanisms of aging. Evolutionary geneticists are now building on these discoveries to see if there is an adaptive component to life span.
Scientist Sarah Tishkoff pulls together a database of African populations—one DNA sample at a time.Peter Nichols
“Africa is one of the most genetically diverse regions of the world,” observes scientist Sarah Tishkoff. “It’s thought to be the site of origin of modern humans. So if we want to learn more about human evolution, we need to be looking amongst African populations.”
Undergraduate Benjamin Laitman looks at the microarchitecture of sleep with fear conditioning.B. Davin Stengel
While everyone may be personally familiar with the phenomenon of sleep, few of us understand what transpires in our own brains between lights out and the sound of the morning alarm. More than the absence of wakefulness or a period of rest, sleep is a complex brain state of great interest to scientists and medical practitioners working in a variety of fields.
Graduate student Lucia Peixoto investigates the molecular machinery of single cell parasites.Peter Nichols
“I’ve always been fascinated by biology,” says Lucia Peixoto. “I knew I wanted to do research by the time I was 12.” She read Darwin’s Voyage of the Beagle before she was a teenager. Her father bought it on a business trip to Ecuador and carried it home to her in Uruguay.

Graduate students Andrew Kemp and Simon Engelhart bring new approaches to studying sea level change.Priya Ratneshwar
Since the last ice age peaked about 20,000 years ago, waters flowing from melting glaciers back into the ocean have caused the global sea level to rise by about 410 feet. This change, though large, is one of many natural oscillations linked to the Earth’s cycle of long-term climate change.
Psychologist Robert DeRubeis searches for a better weapon in the battle against depression.Priya Ratneshwar
Biologist Nancy Bonini uses fruit flies to shed light on neurodegenerative diseases.Priya Ratneshwar
From high school biology classes to the laboratories of Nobel Prize-winning geneticists, the halls of science have long valued the Drosophila melanogaster—the common fruit fly. Despite appearances to the contrary, this tiny insect is a powerful genetic model for the human system.
