Global health officials are intensifying efforts to eradicate yaws, a disfiguring skin disease that infects more than 64,000 people a year in 14 African and southeast Asian countries. But some critics say that the plans could fail, because they don’t take account of discoveries in the past few years that wild primate populations harbour the bacterial infection. That could complicate or foil eradication efforts, they say.
Public-health officials met in Geneva, Switzerland, on 29–30 January to discuss how to expand the eradication programme in 6 of the 14 countries in which yaws is endemic. But they did not discuss the part played by wild animals. “Even if this is not the main cause of re-emerging yaws nowadays, it would jeopardize global eradication,” says Sascha Knauf, who studies neglected tropical diseases at the Leibniz Institute for Primate Research in Göttingen, Germany.
In January, justices of the Supreme Court of India gathered to discuss the country’s national identification system, called Aadhaar. Since 2010, authorities have enrolled 1.19 billion residents, or about 93 percent of India’s population, in the system, which ties fingerprints, iris scans, and photos of Indian citizens to a unique 12-digit number.
Almost a decade later, India is still grappling with the technical, legal, and social challenges of launching the world’s most ambitious government identification program. Aadhaar’s reach and ubiquity has made it a tempting vehicle for centralizing activity, including welfare payments and mobile number registrations. But it has also raised major privacy and security issues. Continue reading
Immunotherapy, which involves adapting immune cells to destroy specific cellular targets, has made a name for itself treating cancer. But over the last few years, a handful of research groups have advanced T-cell therapies for viral infections, and are now on the cusp of commercialization. “Using T cells to target infectious diseases is not a new field,” says immunologist Michael Keller of Children’s National Hospital in Washington, D.C., “but it’s something that’s expanding a great deal.” Continue reading
Engineering student Manuel Dangel of Swiss Federal Institute of Technology (ETH) in Zurich and teammates were walking the racecourse at Formula Student Driverless in Hockenheimring, Germany, earlier this month when they realized that the computerized wheelbarrow they were using to map the course had gone haywire. [See “Students Race Driverless Cars in Germany in Formula Student Competition” 16 August 2017.] Continue reading
