New particles discovered at CERN’s Large Hadron Collider

On July 14, 2015, the LHCb (Large Hadron Collider beauty) experiment at CERN’s Large Hadron Collider announced the discovery of a new form of matter: the pentaquark particle. The theory describing these particles has existed since 1964, when the physicist Murray Gell-Mann proposed that protons and neutrons are made of […]

Promising breakthrough in Cystic Fibrosis research: Nebulization of CFTR gene therapy

For the first time, a non-viral gene therapy in a phase 2 trial has been demonstrated to be advantageous to lung function in people afflicted with cystic fibrosis (1). Normally, people with cystic fibrosis have one or more mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. These mutations […]

Confirmation of climate-induced sex change in reptile populations

Researchers at the University of Canberra have confirmed the first climate-induced change of male bearded dragons into females occurring in the wild. Sex reversal has not evolved among mammals or birds, although it can happen in  rarely in amphibians and in some fish. The Australian central bearded dragon was one […]

Geometry of brain surface linked to genetic ancestry

Researchers at the University of California, San Diego, found that genetic ancestry was correlated with the geometry of the brain’s outer surface. They could use surface patterns to estimate the proportion of various ancestries in American subjects from diverse lineages (1,2). An individual’s ancestry can be determined using small parts […]

Chimpanzee study indicates evolutionary preconditions of morality

According to a new June paper in Human Nature, the reactions of chimpanzees to videos showing violence against an infant chimp reveal that chimpanzees can recognize putative social norms. The chimpanzees did not, however, react in strongly negative ways – showing that chimpanzees may not intervene or protest if the […]

Connection between eye color and alcoholism discovered

Researchers at the University of Vermont have discovered a link between eye color and alcohol dependency in Americans of European descent. Northern Europeans might have evolved light eye traits as an adaption to darker environments because lighter eyes provide a greater sensitivity to light (1). But an increased sensitivity to […]

The inflationary universe: A new discovery in relativistic fluid dynamics could help scientists understand the expansion and fate of the universe.

A discovery in fluid dynamics with cosmological implications

Normally, fluid dynamics and cosmology are widely separate disciplines. Problems like the flow of water through a pipe have little to do with the evolution and fate of the universe; but, as it turns out, if one allow fluids to move near the speed of light, one will find some interesting properties […]

Mission Statement

Founded in 1998, the Dartmouth Undergraduate Journal of Science aims to increase scientific awareness within the Dartmouth community by providing an interdisciplinary forum for sharing undergraduate research and enriching scientific knowledge.

Want to join the DUJS staff?

All the undergraduates of Dartmouth College are welcome to join our staff. Our staff includes students interested in writing, editing, photography, graphics, web design, and more! Please contact us to be added to our e-mail list. Staff meetings are Thursday evenings at 8 pm in Carson L02.
