October 23, 2012 Researchers have found dozens of free apps on iPhones and Androids that promote and glamorize smoking. Many of the apps target children and teens by using cartoons, celebrities and games. Health experts say these apps, downloaded by millions of people, violate bans on tobacco advertising.
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. Several months after infection, the researchers saw that the patients had developed more "broadly neutralizing antibodies," which target different versions of the virus.
October 19, 2012 Thanks to vigorous efforts to eradicate the poliovirus through vaccination, there are only three countries on the face of the earth where polio is still endemic. NPR reporters and editors hosted a chat on Twitter: #chasingpolio.
October 18, 2012 Despite poverty and poor sanitation, the world's second-most populous country is eradicating polio, which has afflicted India for millennia. Health officials hope India's successful war plan against polio will serve as inspiration for its archrival, Pakistan, in its own fight against the disease.
October 18, 2012 Adding a 12-year-old antibiotic to the regimen of patients with highly drug-resistant tuberculosis cured nearly 90 percent of patients in a study involving about 40 people in South Korea. The study, though small, suggests that the battle against the ancient scourge is far from lost.
October 17, 2012 Polio is deadly, but so is what's required to stamp it out once and for all in Pakistan: facing down Islamist extremists. The virus thrives in Pakistan's lawless — and largely inaccessible — tribal regions. To stop polio's spread, health workers must be courageous, clever and relentless.
October 17, 2012 Northern Nigeria is the only region in the world where the number of polio cases is on the rise. International groups have poured money and volunteers into the area to combat the disease. But vaccinators face daunting challenges — from security threats like terrorist bombings to a lack of basic resources like electricity.
October 16, 2012 During the early 20th century, polio killed thousands of American children each summer and paralyzed many more. Now, as the world fights to eradicate the virus globally, we look back at the development of the polio vaccine and its successful deployment around the world.
October 16, 2012 The Department of Health and Human Services' request for comments comes after some have criticized officials for not having enough public discussion about the controversial H5N1 viruses, which were created in the lab to find out if they could mutate and start a pandemic in people.
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 The National Health Service is providing care for short-term travelers. So if you're on holiday and run out of an HIV drug, the NHS will help out, gratis. But if you're thinking of going for a long time to get free care, you're probably out of luck.
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. Now top scientists in the field continue the debate about the work, publishing six commentaries for and against the end of the moratorium.
