Scientists Identify a New Organ

Scientists Identify a New Organ

By Sam Neff A recent study conducted at the NYU School of Medicine has defined a new organ in the human body (1). It is called the interstitium, and scientists have known of this body region previously as a matrix of flowing fluid enmeshed in collagen and elastin fibers (2). […]

Marine Mammals: Size and Energy Constraints in Aquatic Environments

Marine Mammals: Size and Energy Constraints in Aquatic Environments

By Anna Brinks ’21       The largest mammal on Earth, the blue whale, is one of the many gentle goliaths populating our oceans. With a tongue that weighs as much as an elephant, this aquatic mammal consistently has had a larger average size than its terrestrial counterparts. The […]

Slow, rhythmic brainwaves linked to consciousness

Slow, rhythmic brainwaves linked to consciousness

By John Kerin ’20   If you closely observe an MRI of the human brain, you will notice ultra-slow waves that pass through in a heartbeat-like rhythm at approximately 1-second intervals. This pattern was recognized decades ago, however it was thought of as MRI noise and insignificant static until recently. […]

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 […]

Neural Responses Predict Friendships

Neural Responses Predict Friendships

Neural Responses Predict Friendships Megan Zhou ‘21 An example of a social network diagram. (Source: Wikimedia Commons) The proverb that “birds of a feather flock together” is based on the concept of homophily—the tendency of individuals to associate and bond with similar others. Throughout history, this trend has created evolutionary […]

Sewage Can Soon Be Converted into Bio-based Fuel

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.
