HIV survival improves if patients stay in care

...east one visit in all four quarters, 18 percent in three of four quarters, 11 percent in two of four quarters and 6 percent in only one quarter. The researchers then looked at how long the patients survived after that first year. Sixteen percent of the patients died. Those who had poorer retention in ca...

DOE JGI sets 'gold standard' for metagenomic data analysis

Global climate models suggest that Micronesia is particularly vulnerable to climate change over the next millennia, and will be l...

Female-led infanticide in wild chimpanzees
