Research: Persistent Explosives Present a Problem

Introduction
During winter and spring of 2008 I had the opportunity to participate in the Women in Science Project (WISP) internship program for first-year students. As an intern in the Biochemical Sciences branch at the Cold Regions Research and Engineering Laboratory (CRREL), I conducted research in the laboratory of Dave Ringelberg, sponsored by Jay Clausen. In [...]

Battle of the Sexes

In the summer of 1925, Russian geneticist Sergey Gershenson collected 19 female fruit flies of the species Drosophila obscura from a forest near Moscow. He brought the captured flies back to his laboratory and mated them with normal males to study their offspring. By the second generation of matings, Gershenson noticed a puzzling trend: some [...]

Remembering Karen Wetterhahn

On June 8, 1997, the Dartmouth community suffered a tragic loss: the death of Karen Wetterhahn, a beloved professor. A specialist in metal toxicology, Wetterhahn had spent over 20 years in the Chemistry Department elucidating the mechanisms of chromium and nickel metabolism in cells. In August of 1996, while following standard safety protocol, Wetterhahn spilled [...]

A Decade of Science at Dartmouth

During the ten years of the DUJS’s existence, science at Dartmouth has seen breakthrough after breakthrough. Once the site of the first clinical x-ray in North America, Dartmouth College over the last decade has had a hand in the discovery of microRNA and cancer chemoprevention, and its researchers have worked to produce ethanol from biomass [...]

Ten Years of the DUJS

We propose a medium of scientific expression for the students, by the students. The community needs a medium that will focus on recognizing and unifying Dartmouth undergraduate research while also, motivating more students to get involved in the advancement of scientific thought. We need some entity to become the source of scientific dialogue and expression [...]

Research: Army Ant Emigration

Diel Emigration and Foraging Behaviors of the Army Ant Eciton hamatum (Subfamily Ecitoninae)
As predators of many social insects and larger arthropods, army ants are a key component of tropical forest ecosystems. Specifically, their foraging behaviors and food preferences can affect forest invertebrate abundance and composition. To better understand army ant behavior, we observed foraging and [...]

Type Ia Supernovae: Properties, Models, and Theories of Their Progenitor Systems

Introduction
Supernovae are magnificent phenomena in the night sky, and have always been a marvel to human beings. A supernova is a stellar explosion that emits a burst of radiation resulting in an extremely luminous object that may outshine its entire host galaxy before fading from view over several weeks or months. One class of supernovae, [...]
