Cosmologists have made the most sensitive and precise measurements yet of the polarization of the cosmic microwave background.
Chemical fingerprints of the element nitrogen vary by extremes in materials from the molecules of life to the solar wind to interstellar dust. Ideas for how this great variety came about have included alien molecules shuttled in by icy comets from beyond our solar system and complex chemical scenarios.
Keith Brueckner, University of California, San Diego's founding physicist, died September 19. He was 90.
Biochemists working at the University of California, San Diego, have developed a program that predicts the placement of chemical marks that control the activity of genes based on sequences of DNA. They describe their analysis and report results from its application to human embryonic cells in a paper…
Our immune system copes with a multitude of threats using a mix-and-match system to create millions of different antibodies.
Sulfur signals in the Antarctic snow have revealed the importance of overlooked atmospheric chemistry for understanding climate, past and future.
Embryonic stem cells can develop into a multitude of cells types. Researchers would like to understand how to channel that development into the specific types of mature cells that make up the organs and other structures of living organisms.
An elusive state of matter called superconductivity could be realized in stacks of sheetlike crystals just a few atoms thick, a trio of physicists has determined.
Taking a moment to pause and relax can help if you find yourself in a tight spot. This strategy can work for molecules as well as people, it turns out. Researchers at UC San Diego have found that DNA packs more easily into the tight confines of a virus when given a chance to relax.
It's no surprise that official tallies of the inhabitants of a city miss many residents. Not everyone wishes to be counted, particularly not those who lack legal permission to be there, and censuses are infrequent, if they happen at all.
