Differences divide us. Human society fractures along lines defined by politics, religion, ethnicity, and perhaps most fundamentally, language. Although these differences contribute to the great variety of human lives, the partitions they create can lead to conflict and strife, impeding efforts toward social justice and economic development.
DARPA, the U.S. Defense Advanced Research Projects Agency, has awarded $6 million to a team of researchers to develop nanotechnology therapies for the treatment of traumatic brain injury and associated infections.
Astronomers have spotted a galaxy that is igniting new stars faster than ever seen before. Measurements from several instruments show that gas in this galaxy is condensing to form stars close to the maximum rate thought possible.
Ocean biology alters the chemical composition of sea spray in ways that influence its ability to form clouds over the ocean. That’s the conclusion of a team of scientists using a new approach to study tiny atmospheric particles called aerosols that can influence climate by absorbing or reflecting sunlight and seeding clouds.
Particles from the upper atmosphere trapped in a deep pile of Antarctic snow hold clear chemical traces of global meteorological events, a team from the University of California, San Diego and a colleague from France have found.
Astronomers will begin an ambitious new project to measure light from thousands of distant galaxies this weekend. Over the next four years, they will spend 47 nights surveying the sky for signals from a time when the Universe was just 2 to 4 billion years old and the earliest galaxies were forming.
Blocking a single tiny blood vessel in the brain can harm neural tissue and even alter behavior, a new study from the University of California, San Diego has shown. But these consequences can be mitigated by a drug already in use, suggesting treatment that could slow the progress of dementia associated with cumulative damage to minuscule blood vessels that feed brain cells. The team reports their results in the December 16 advance online edition of Nature Neuroscience.
Ten professors at the University of California, San Diego have been named Fellows of the American Association for the Advancement of Science, the nation’s largest scientific organization. They are among 702 members selected this year by colleagues in their disciplines to be honored by the association for “scientifically or socially distinguished efforts to advance science or its applications.”
Sparse halos of neutrinos within the hearts of exploding stars exert a previously unrecognized influence on the physics of the explosion and may alter which elements can be forged by these violent events.
