Muscle memory “in the flesh”

Muscle memory “in the flesh” By Brenda Miao brenda.y.miao.19@dartmouth.edu The term “muscle memory” has been used colloquially to describe the development and refinement of a specific motor skill through repetitive motion, but until recently, it was unknown whether muscles actually retain a physical imprint of past activity. Researchers at Keele […]

Geisel Lecture: Christopher Brett, Intraluminar Fragments

Geisel Lecture: Christopher Brett, Intraluminar Fragments Samuel Reed ‘19 Intraluminar Fragments (ILFs) are bodies created within lysosomes during their fusion. This event has mainly been documented in yeast but is thought to be conserved among all eukaryotes, as is the case with other lysosomal pathways. ILFs were originally discovered by […]

One Step Closer to Nuclear Fusion

One Step Closer to Nuclear Fusion

One Step Closer to Nuclear Fusion Ted Northup ’21 According to a recent report on nuclear fusion, scientists may have discovered an optimal model for regulating plasma turbulence while still achieving desired functional results. A Brazilian researcher, Vinicius Duarte of the Princeton Plasma Physics Laboratory, recently developed a conceptual regulation […]

New threat to the ozone layer

New threat to the ozone layer

New threat to the ozone layer   By: John Beute ‘20, 2/20/18   The extent of the ozone hole over Antarctica (Source: Wikipedia)   In 1987, the UN enacted an emergency measure known as the Montreal Protocol to ban the use of chlorofluorocarbons—more commonly known as CFCs. Scientists had discovered […]

Sewage Can Soon Be Converted into Bio-based Fuel

Recent research findings at the Department of Energy’s Pacific Northwest National Laboratory (PNNL) has shown that wastewater treatment plants may have the potential to produce biocrude oil, which is a petroleum-substitute synthetic fuel, from ordinary sewage (1). The technological process being considered is called hydrothermal liquefaction (HTL) (2). In HTL, […]

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.
