An international team of astronomers composed of UC San Diego astrophysicists has discovered three Earth-sized planets orbiting near the “habitable zone” of an ultracool dwarf star, the first planets ever discovered around such a tiny and dim star.
Chemists at UC San Diego have created an “adaptive protein crystal” with a counterintuitive and potentially useful property: When stretched in one direction, the material thickens in the perpendicular direction, rather than thinning as familiar materials do. And when squeezed in one dimension, it shrinks in the other rather than expanding, and gets denser in the process.
When does DNA behave like sand or toothpaste? When the genetic material is so densely packed within a virus, it can behave like grains of sand or toothpaste in a tube. That’s essentially what biophysicists at UC San Diego discovered when they began closely examining the physical properties of DNA jammed inside viruses.
University of California San Diego bioengineers have created what they believe to be the first online search engine for functional genomics data. This new search engine, called GeNemo, is free for public use at: http://www.genemo.org.
After World War II came to an end in 1945, the mass killing and sheer devastation wrought by the Nazis off the battlefield began to emerge in shocking detail. Some 11 million civilians—both Jews and non-Jews, including about 1.5 million children—were killed during the Holocaust.
When Sarah was 3 years old, she turned to her mother and asked when she was going to get the same body parts as her brother.
