Genome Wide Association Studies and Rice

Because 92% of rice is consumed in the country that it is harvested, it is very diverse with two subspecies and five subdivisions. Source: http://en.wikipedia.org/wiki/File:Rice_grains_(IRRI).jpg

To produce the most resilient strain of rice, breeders would conventionally cultivate two different hardy species, but Susan McCouch, a professor of plant breeding and genetics at Cornell University, has found evidence otherwise. In her Friday Oct. 4, 2013 seminar at Dartmouth College, McCouch discussed discoveries about rice and what...

Gravity may limit cell growth and size limit. Professor Cliff Brangwynne of the Chemical and Biological Engineering Department of Princeton University presented his research on Nuclear Actin, RNA Droplets and Gravity on Tuesday, September 24, explaining the research that led to his recent conclusion. Typical eukaryotic cells are about 10µm...

 
 

Branched Flow of Waves and Rays

A rogue wave is a terrifying thought for a sailor, a wave 50 times as tall as normal waves. The branched flow of waves and rays may seem like an esoteric topic in theoretical physics. However, this discovery has applications in many diverse fields ranging from oceanography to acoustics. On...

Mechanisms and Consequences of Chromosome Mis-segregation and Aneuploidy

Daniela Cimini, an associate professor of biological sciences at Virginia Tech, spoke at the biochemistry seminar on April 30th. In an unusual move, she told two stories about the consequences of mis-segregation and aneuploidy that she had encountered instead of discussing just her published research.

On April 30th, Daniela Cimini, an associate professor of biological sciences at Virginia Tech, was invited to speak at the biochemistry seminar. Rather than discussing her published research, she told two stories about the consequences of mis-segregation and aneuploidy that she had encountered. Mis-segregation involves a faulty separation of chromosomes...
