Rio Olympic Games: 'Super bacteria' discovered in Rio's waters - CNN.com
CNN reports: "A group of Brazilian scientists has detected a drug-resistant bacteria growing off some of Rio de Janeiro's most stunning beaches, in research being published a month before the city hosts the 2016 Olympic Games. [...] The news comes as Rio prepares to host hundreds of thousands of athletes and tourists during next month's Summer Olympics."

Comment: I won't be participating in this public health experiment, I'll be safely watching the games on TV, but hats off to those brave souls volunteering to gamble their health in Rio.
