Affirmative action is a contentious issue across the globe, hotly debated in countries such as India, Sri Lanka, Malaysia, Nigeria and Brazil, as well as in the United States. While the direct effects of affirmative action on college admissions are well known, new evidence from India shows that affirmative action has indirect benefits on the behavior of underrepresented high school students, who tend to stay in school longer when they know higher education is within reach.
The multiplication of genes located in extrachromosomal DNA that have the potential to cause cancer drives poor patient outcomes across many cancer types, according to a Nature Genetics study published Aug. 17, 2020 by a team of researchers including Professors Vineet Bafna and Dr. Paul Mischel of the University of California San Diego and Professor Roel Verhaak of Jackson Laboratories.
A series of simulations using multiple supercomputers, including Comet at the San Diego Supercomputer Center (SDSC) at UC San Diego, suggests that when the neutron stars’ masses are different enough, the result is far noisier. The models predicted an electromagnetic ‘bang,’ which isn't present when the merging stars' masses are similar, according to researchers.
The enzyme serine palmitoyl-transferase can be used as a metabolically responsive “switch” that decreases tumor growth, according to a new study by a team of San Diego scientists, who published their findings Aug. 12 in the journal Nature. By restricting the dietary amino acids serine and glycine, or pharmacologically targeting the serine synthesis enzyme phosphoglycerate dehydrogenase, the team induced tumor cells to produce a toxic lipid that slows cancer progression in mice.
