June 2, 2013 The strange disease known as nodding syndrome affects only children, and only in parts of East Africa. The illness begins with nodding of the head and ends with massive physical and cognitive deterioration; its cause has eluded epidemiologists. Treating 3,000 affected children has been left to Ugandans.
May 29, 2013 All told, the fatality rate for confirmed infections with the virus has been more than 50 percent. But the true fatality rate won't be clear until the fuller extent of cases, some probably much milder, becomes known.
May 28, 2013 Doctors in China concluded that early treatment of bird flu cases with Tamiflu could help patients even days after infection. But the doctors also found in two cases that the virus apparently became resistant to the antiviral drug.
May 23, 2013 The virus's ability to move between these mammals might not bode well for humans. So far, it appears that H7N9 doesn't pass easily between people, but it could mutate over time and pose more of a threat.
May 22, 2013 A plant scientist at Mars Inc. has appealed to the world's biggest life sciences companies to help him — by sharing what they already know about 100 crops that could provide better nutrition in Africa. But can the kings of agricultural intellectual property get onboard with open source agricultural information for Africa?

May 9, 2013 The two makers of HPV vaccines have agreed to lower the prices for their vaccines to less than $5 a shot for low-income countries. The cheaper vaccine may make it easier to vaccinate girls in places where the risk of death from cervical cancer is greatest.
