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). […]

 
 

The BioPen and the Scientific Community

The BioPen and the Scientific Community

The advent of BioPens, “handheld surgical pens” that can bioprint artificial tissues for implantation, now provides surgeons with unprecedented control in correcting structural defects (1).  Rather than printing entire tissues and surgically implanting them into the recipient, these pens enable surgeons to add layers upon layers of tissue, each of […]

 
 

The Chemistry of Primes

Every integer can be represented uniquely as a product of primes (Source Krishan Canzius).

On April 27, Professor Melanie Wood from the University of Wisconsin-Madison gave a lecture at Dartmouth. The talk was titled “The Chemistry of Primes” and focused on prime numbers in different number systems. The lecture mostly consisted of a review of old work on the subject, but Wood concluded with […]

 
 
 
 

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.
