Humans’ Endogenous Retroviruses Influence Our Brain Development

Humans’ Endogenous Retroviruses Influence Our Brain Development






A recent article in ScienceDaily based on a publication in the journal Cell Reports describes a hot topic in neurobiology: the contribution of endogenous retroviruses (ERVs) towards human brain development (1,2). Perhaps the most famous retrovirus is HIV, the Human Immunodeficiency Virus, shown in Figure 1. Unlike HIV, however, ERVs are […]

 
 

When stress becomes deadly

Stress has long been associated with increased risk of cardiovascular disease. New research suggests that a potential explanation for this correlation is due to increased activity of the amygdala, which may upregulate bone marrow activity and arterial inflammation.

Whether it’s from upcoming exams, unpaid bills, or simply a long day at work, stress is an inevitable part of life. However, poor stress management can lead to severe health impairments, with several studies showing that chronic stress is particularly correlated with higher risk of heart disease, although scientists have […]

 
 

Physicists Cool Microscopic Drum to Near Absolute Zero

Physicists Cool Microscopic Drum to Near Absolute Zero






According to a paper recently published in Nature, researchers at the National Institute of Standards and Technology (NIST) have cooled a vibrating drum to an unprecedented one-fifth of a quantum of energy, approaching the previously perceived limit of absolute zero (1). Scientists use temperature to measure the thermal motion of […]

 
 

Novel Approach to Biological Circuit Design Allows Scientists to Track Cell Lineages

A recent article in ScienceDaily reviews a new approach in Synthetic Biology that allows cells to respond to a series of input stimuli and simultaneously remember the order of these stimuli over many generations (1). As noted by the senior investigator, Timothy Lu from MIT, combining computation with memory creates […]

 
 

Storing digital data in DNA

Storing digital data in DNA






From 80 kilobyte floppy disks, developed in 1971, to 1 terabyte portable hard drives, introduced in 2007, data storage has increased exponentially over the past decades. Now, researchers at the University of Washington, in collaboration with Microsoft, have come up with a new technique for storing data that could further […]

 
 
 
 
 

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.
