The Obama administration has announced $60 million in additional funding to fight AIDS transmission in sub-Saharan Africa, and a new special envoy to raise global awareness about the deadly disease: Ellen DeGeneres. Secretary of State Hillary Rodham Clinton says the actress will “bring her sharp wit and big heart, and her impressive TV audience and 8 million followers on Twitter” to support U.S. efforts to save the lives of those suffering from HIV/AIDS.

Clinton says the money will help scale up and assess new prevention strategies. She said Tuesday that more effective prevention methods were driving infections down, making it possible to treat more people. She said that is allowing health campaigners for the first time to “get ahead of the pandemic,” and make progress toward establishing an AIDS-free generation.

Former Survivor winner Ethan Zohn’s cancer has returned. People reports the reality star — who was in remission from Hodgkin’s lymphoma — was informed by doctors Sept. 14 that the cancer is in his chest. But there is some good news: The cancer hasn’t spread. “It’s localized in my lung area,” Zohn told People. “But it’s good that it’s not all over my body.”

Zohn has started chemotherapy, and plans to undergo a stem-cell transplant from one of his brothers. The Survivor is keeping his hopes up, and even plans to run in the New York City Marathon Nov. 6. “The doctors think I’m crazy but they gave me the okay,” Zohn told People. “Cancer isn’t going to slow me down. I want people to know that you can still live a fulfilled life and move forward.”
