Researchers at University of California, San Diego School of Medicine report that more than one in four female sex workers in two Mexican cities on the U.S. border entered the sex trade younger than age 18; one in eight before their 16th birthday. These women were more than three times more likely to become infected with HIV than those who started sex work as adults.
NSF has awarded Calit2, CITRIS and nearly 20 participating institutions a $5 million, 5-year grant to create the Pacific Research Platform to enable a science-driven data freeway system in the western U.S. with speeds 1,000 times faster that today's traffic between campuses.
A $300,000 gift from the Moxie Foundation will support computer scientists at the University of California, San Diego who are researching and developing high-tech assistive technology to help individuals with disabilities.
The San Diego Supercomputer Center (SDSC) at the University of California, San Diego, has appointed Shawn Strande as deputy director for the Center, effective immediately. Strande, who worked for both SDSC and UC San Diego in various capacities since 1992, succeeds Richard L. Moore, who retired in June after 13 years with SDSC.
Ethiopians have lived at high altitudes for thousands of years, providing a natural experiment for studying human adaptations to low oxygen, a condition known as hypoxia. One factor that may enable Ethiopians to tolerate high altitudes and hypoxia is the endothelin receptor type B (EDNRB) gene. Researchers at University of California, San Diego School of Medicine now find that mice with lower-than-normal levels of EDNRB protein are remarkably tolerant to hypoxia.
Scientists have discovered an exception to an otherwise globally observed pattern—usually biodiversity is greatest in the tropics and decreases toward the poles. The research team collected snails and parasites from 43 field sites spread across five countries and found that parasite prevalence, diversity, and competition rates all increased at higher latitudes, reversing previous ideas.
