For the next few days, you Science Friday fans will be hearing a familiar voice. Joe Palca will be filling in for Lynn Neary... who was filling in for Neal Conan. Ah, it's complicated. Let me just fill you in on what's happening today.

The Obama Administration plans to close down the prison at Guantanamo Bay in Cuba due in part to concerns about the treatment of prisoners there. In our first hour, Rajiv Chandrasekaran, former Baghdad bureau chief for the Washington Post, and Debra Burlingame, co-founder of 9/11 Families for a Safe and Strong America, will explore how detainees are treated at Guantanamo, and what may happen to them once they leave the prison. We're working on our opinion page segment as I type this, so stayed tuned.

Juicycampus.com, a popular college gossip/rumor mill website, closed up shop. So what is the future of the internet when it comes to privacy vs. free speech? In our second hour, we'll discuss whether or not there should be complete, total, unencumbered free speech on the Internet... or if there should be some restrictions? At the end of the hour, we'll talk with author Vikas Swarup about his surprising reaction to the movie Slumdog Millionaire snagging the Oscar for Best Picture in last night's Academy Awards ceremony. The movie is based on Swarup's book "Q&A."
