Welcome to SCIENCE FRIDAY. I am Ira Flatow. A few weeks ago, we talked about the discovery of new exoplanets, those planets outside of our solar system. There were the first Earth-sized exoplanets, and we had another exoplanet smack dab in the middle of the Goldilocks Zone, you know, where liquid water could exist. That was another first.
Speaking of dark matter and space-time, one of the major questions about our universe is how did it all come into being, and my next guest tackles that question in his new book, "A Universe from Nothing: Why There is Something Rather than Nothing." Lawrence Krauss is also a foundation professor and director of the Origins Project at Arizona State University in Tempe. He's also in our NPR Washington studios. Welcome back, Lawrence.
LAWRENCE KRAUSS: It's always good to be back, Ira.
This is SCIENCE FRIDAY. I'm Ira Flatow. We talk many times about the rise of drug-resistant bacteria, germs that resist most antibiotics, except for a precious few. A case in point is tuberculosis. But now comes word of a strain of TB that is totally drug-resistant, TDR TB as doctors are calling it. There are no second-choice antibiotics here. We simply have no drugs to fight this superbug. There are no weapons left. And it has now infected a dozen patients in India.
Jim Brown, Dennis Rodman and O.J. Simpson are all former professional athletes who've tried their hand at acting. Showbiz might seem like a natural path for guys with big egos and million-watt personalities, but Eddie George is a former NFL player who's taken a different path to the limelight.
He's joining a fraternity of actors that includes Charlton Heston in playing William Shakespeare's Julius Caesar.
The scene where Marcus Brutus kills Caesar is probably the most famous death scene in all of theater. It's where those famous words, "Et tu, Brute?" are uttered.
In Texas today, conservative Christian and evangelical leaders begin two days of meetings to discuss political strategy, and perhaps to coalesce around a Republican presidential candidate other than front-runner Mitt Romney, the former governor of Massachusetts.
Joran van der Sloot, the 24-year-old Dutchman who remains the prime suspect in the still-unsolved 2005 disappearance of Alabama teen Natalee Holloway in Aruba, was just sentenced to 28 years in prison for the 2010 murder of a woman in Peru.
NPR's business news starts with efforts to streamline the federal government.
(SOUNDBITE OF MUSIC)
GREENE: President Obama is asking Congress, today, to give him the power to consolidate certain U.S. agencies. Doing that, he says, will reduce the number of federal jobs and make government more efficient.
PRESIDENT BARACK OBAMA: The government we have is not the government that we need. We live in a 21st Century economy, but we've still got a government organized for the 20th Century.
