Physcomitrella patens and the cytoskeleton’s role in cell development

Recent research using moss may give more insight into how the components of the cytoskeleton communicate with each other. The cytoskeleton, a supportive, intracellular structure, is integral to cellular function. Composed of microtubules, actin filaments, and intermediate filaments, the cytoskeleton transports proteins and maintains cellular integrity. However, the mechanisms it […]

 
 

Magnetic bacteria show promise as efficient vehicle for delivering tumor-fighting drugs

Magnetic bacteria show promise as efficient vehicle for delivering tumor-fighting drugs

Researchers funded by the National Institute of Biomedical Imaging and Bioengineering (NIBIB) have found that magnetic bacteria can act as a possible tool for efficiently transporting drugs to tumors in the human body. One of the largest issues in cancer treatment is being able to deliver a sufficient amount of […]

 
 

Prehistoric Conditions Predict Extended Drought in California

Prehistoric Conditions Predict Extended Drought in California

Evidence of prehistoric droughts indicate current levels of greenhouse gases could lead to century-long droughts, according to researchers at the University of California, Los Angeles. Led by UCLA professor Glen MacDonald, the study examined how radiative forcing—a climatic warming process involving sun spots, changes in the earth’s orbit, and decreases […]

 
 

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

Image credit to Liang Zong and Yan Liang. Published with permission from MIT News Office. Scientists like Dr. Lu at MIT are combining electrical engineering principles with biology, viewing cells as “state machines”.

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 […]

 
 

The Moral Dilemmas of Autonomous Vehicles

Autonomous Vehicles in Action. (Source: csctbsc http://csctbsc.com/automated-cars/).

By Chiemeka Njoku There are certain situations for which automated vehicles (AVs) must be programmed to either preserve the life of the passenger or to sacrifice the passenger for the life of a passerby. Experimenters conducted a survey to determine what the average driver thinks of these moral dilemmas (1). […]

 
 
 
 

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.
