On Sunday night, while the rest of us were ooohing and aaahing over gymnastics, a bunch of propeller heads at NASA and the Jet Propulsion Laboratory were flawlessly steering a billion-dollar robotic space laboratory the size of a minivan to a landing on Mars.

Missions engineers Bobak Ferdowsi and Adam Steltzner — whose hairstyles have led them to be nicknamed "Mokawk guy" and "Elvis guy," respectively — are two of the guys behind the landing of the Mars rover Curiosity, and very well might be the Sexiest Nerds Ever.

Carmelita Jeter made sure everyone understood what Team USA had just accomplished. She pointed toward the digital clock with the baton as it flashed a time of 40.82 seconds.

Jeter, Tianna Madison, Allyson Felix and Bianca Knight had just gotten a gold medal in the 4 X 100m relay and they did so while shattering the world record by a little more than half a second.

After serving as speaker of the House, publishing several historical novels and running for president, what's next for Newt Gingrich?

One possible third act, Gingrich told NPR staffers on Friday, could be sharing a television studio with his wife, Callista.

"We're kind of intrigued with the idea of doing a daily show, which would change our lives pretty dramatically," Gingrich said. "But if we do it, we want it to be closer to Regis and Kathie Lee than to Bill O'Reilly or Hardball."

A little more than a week after a major plagiarism scandal brought down science wunderkind Jonah Lehrer, Time magazine said it was suspending Fareed Zakaria's column for a month.

Zakaria is an influential and respected commentator on foreign policy and also hosts a show on CNN called Fareed Zakaria GPS.

When writer David Rakoff died Thursday at the age 47, he was barely the age he said he was always "meant" to be. In his 2010 memoir, Half Empty, he wrote, "Everyone has an internal age, a time in life when one is, if not one's best, then at very least one's most authentic self. I always felt that my internal clock was calibrated somewhere between 47 and 53 years old."

Rakoff died in New York City after a long struggle with cancer — an ordeal that he wrote about with sobering honesty and biting wit.

The Bahamas men's team has won the 4x400m relay, edging past a surprisingly quick U.S. team to take the gold medal. It was the first gold medal for any male athlete from the Bahamas. The quartet ran a time of 2:56.72, setting a national record. The U.S. set a season best of 2:57.05 to take silver.

Trinidad and Tobago took the bronze medal, just ahead of Great Britain.

The Bahamas led the race after the first lap, with the U.S. running in second. And the two teams' runners stayed ahead of the pack, extending their lead to make it a two-team race.
