The process of morphogenesis, by which an organism develops its shape, is one of the least well understood pillars of developmental biology (1). Research on model organisms has emphasized the importance of particular genes and molecular pathways. However, current models of how these directly relate to growth on the macroscopic […]

 
 

Neural Networks Rival the Primate Brain at Object Recognition

Neural networks are machine learning algorithms inspired by the brain.

A central problem in computer vision is that of designing algorithms that can competently accomplish tasks that humans can easily do, such as recognizing objects. Recently, neuroscientists at MIT found that the latest artificial deep neural networks (DNNs) are able to rival the performance of the primate brain at this […]

 
 

2014: The Hottest Year Yet

High temperatures in 2014 helped contribute to the California drought.

The past year was the hottest on record since at least 1891, the Japan Meteorological Agency (JMA) announced on January 5th. The JMA reports that the average temperature was 0.27°C warmer than the 1981 to 2010 baseline average. (1) This finding was not unexpected. In December 2014, the United Nations’ […]

 
 

Computer Science Researchers Devise Hold ‘em Algorithm

Computer scientists at the University of Alberta have written an effectively unbeatable algorithm for heads-up limit hold’em.

Computer science researcher Michael Bowling and his colleagues at the University of Alberta, along with Finnish software developer Oskari Tammelin, have devised an algorithm to solve a variant of poker called heads-up limit hold’em (HULHE) (1). The authors’ strategy plays HULHE so flawlessly “as to render pointless further work on […]

 
 

Cancer: A Manifestation of “Bad Luck”?

A linear correlation equal to 0.804 suggests that 65% of the differences in cancer risk among different tissues can be explained by the total number of stem cell divisions in those tissues.  Thus, the stochastic effects of DNA replication appear to be the major contributor to cancer in humans. (Tomasetti & Vogelstein, 2015)

A positive correlation between random mutations in replicating cells and the onset of adult cancer was found at the Johns Hopkins Kimmel Cancer by Cristian Tomasetti and Bert Vogelstein. That “bad luck”—that is, random mutations during DNA replication, environmental factors, and genetic disposition–contributes to cancer incidence is a well-known fact […]

 
 
 
 

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.
