October 22, 2012 Researchers in South Africa tracked how the evolution of the virus in two infected woman shaped the antibodies they produced to fight it.

October 11, 2012 By tracking nearly 15 million cellphones in Kenya, scientists mapped out how malaria spreads through the Texas-sized country. The findings pinpoint areas where efforts to control malaria would be the most effective. One day, the data may help guide alert systems for phones that remind travelers to use bed nets.
October 9, 2012 Because of fears that lab-altered bird flu viruses could cause a deadly pandemic if they ever escaped the lab, scientists agreed to a moratorium on mutant H5N1 flu research eight months ago.

October 5, 2012 At first it seemed likely that the two known cases of illness from the new cousin-of-SARS virus may have been exposed in or near the Saudi Arabian city of Jeddah.
