Q: Durban (CNN) A vaccine against HIV will be trialed in South Africa later this year after meeting the criteria needed to prove it could help fight the epidemic in Africa. In 2015, 2.1 million new infections were reported -- two-thirds of which occurred in sub-Saharan Africa. A small trial, known as HVTN100, took place in South Africa in 2015 to test the safety and strength of immunity the vaccine could provide, ahead of any larger-scale testing in affected populations. Two-hundred and fifty-two healthy volunteers were enrolled to receive either the vaccine, known as ALVAC-HIV/gp120, or a placebo to compare the extent of immune response generated. The results were presented Tuesday at the 21st International AIDS Conference in Durban, South Africa.A new form of HIV vaccine has proved safe enough for clinical trialsThe vaccine will be trialed in 5,400 people from November 
 Question:The vaccine was improved for use in the higher-risk populations of sub-_, where a different subtype of the virus also exists.

A: Durban

Q: (Ars Technica) -- These days, it seems, it's not enough for a digital device to just play games. To keep up with the smartphones and tablet computers of the world, any game system needs to at least nod in the direction of cloud-based and social networking "apps" that are all the rage with the kiddies. Sony's PlayStation Vita has now done exactly that, launching free downloadable Netflix, Twitter and Flickr apps in conjunction with the system's official debut Wednesday (though pre-orderers have had the system for a week now). Your very first encounter with two of these apps foreshadows the occasionally awkward experience to come. When you first load up Twitter or Flickr on your Vita, you're asked to click a button that opens up a web browser where you can log in to the service.The PS Vita is primarily a gaming device but also runs apps for Netflix, Twitter and other servicesThe Vita screen's resolution isn't quite "HD," but high-definition content still looks goodYou can easily search through tweets with a handy conversation viewFlickr has a nice interface with quick access to photostream, favorites and contacts 
 Question:_ rounds out the Vita's initial round of apps, with quite possibly the nicest interface of the bunch.

A: Ars Technica

Q: (CNN) The case of college football player Michael Keck has added more fuel to the fire about whether young children should play football. Despite the fact that Keck, 25, never played professional football, he was diagnosed with chronic traumatic encephalopathy, the Alzheimer's-like disease that also claimed the likes of former Chicago Bears safety Dave Duerson and former San Diego Chargers linebacker Junior Seau, and with equal severity. "I was surprised how extensive it was," said Dr. Ann McKee, professor of neurology and pathology at Boston University. She and her team have evaluated 170 brains to understand the pathology of CTE. The telltale sign of the disease is tangles of the protein tau, which takes over parts of the brain. They result from repeated hits to the head.Chronic traumatic encephalopathy results from repetitive hits to the headThe disease has symptoms that are similar to Alzheimer's44 of 55 college football players were found to have CTE
