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 […]

 
 

Novel 3-D Printing Ink Shows Promise for Bone Regeneration

Novel 3-D Printing Ink Shows Promise for Bone Regeneration






Engineers at Northwestern University have recently produced a synthetic bone material, specifically aimed to treat pediatric patients with bone defects using an innovative 3-D printing system. Many complications arise during bone implantation surgery, especially for children. Bone used for surgery is typically extracted from other parts of the body in […]

 
 

New research explains how aquatic birds dive safely at high speeds to hunt prey

New research explains how aquatic birds dive safely at high speeds to hunt prey






A research team at Virginia Tech has developed a mechanism to explain how seabirds safely plunge into the ocean when looking for food despite their slim necks (1). In order to surprise their targets, many species of seabirds dive into the ocean at speeds faster than 60 miles per hour. […]

 
 

Exploring Neural Mechanisms Underlying Visual Object Recognition

Exploring Neural Mechanisms Underlying Visual Object Recognition






James DiCarlo, Department Head and Professor of Neuroscience and Investigator at MIT, discussed his research on the neural mechanisms underlying humans’ seemingly effortless ability to solve complex problems of object recognition. Humans rapidly and accurately analyze visual environments, extracting latent content—such as category information, position, and size—from a pattern of […]

 
 
 
 
 

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.
