Science Friday

Fridays 1 - 3 p.m.
  • Hosted by Ira Flatow

Science Friday is a weekly science talk show, broadcast live over public radio stations nationwide from 2-4 p.m. Eastern time. Each week, we focus on science topics that are in the news and try to bring an educated, balanced discussion to bear on the scientific issues at hand. Panels of expert guests join Science Friday's host, Ira Flatow, a veteran science journalist, to discuss science -- and to take questions from listeners during the call-in portion of the program.

What’s the future of your commute?

Oct 23, 2016

For commuters in Manhattan, the ride-hailing service Uber now offers a $5 flat fare for carpooling with other riders headed in the same direction.

Recently, the company inked a deal with the city of Summit, New Jersey, to offer commuters subsidized rides to and from the train station, as the area suffers from parking congestion. Does the future of commuting start with an app? Experts say there could be real benefits to merging ride-booking technology with our commutes, but for the moment, not everyone — or every place — stands to gain equally.

Mike Massimino is one of the few people on the planet who has looked back down on Earth from the Hubble Space Telescope, which is now about 340 miles above us in space. Massimino got this chance twice, in fact, on separate repair missions.

Every single person sports a pattern of lines on their kisser. They’re laid down early in development and stay essentially unchanged throughout life.

“Lip prints are very much like fingerprints,” says Mary L. Marazita, a professor in the department of oral biology at the University of Pittsburgh’s School of Dental Medicine. “They’re unique to a person.”

How can we save California's forests?

Oct 17, 2016

To say trees in California are having a tough time may be an understatement. Years of drought conditions and warmer temperatures have stressed millions of trees, and surging numbers of bark beetles, the rice-grain size invaders that attack tree bark, are dealing a death blow.

Cars in the cloud

Oct 16, 2016

We may still be a few years away from being shuttled around by fully autonomous vehicles, but cars on the road right now already feature powerful processing equipment like video cameras and radar.

And at the Paris Motor Show, which opened on Oct. 1 and ends Sunday, Oct. 16, Audi, Mercedes-Benz, and BMW unveiled cars that use sensors to find open parking spots, read road signs and determine the best route to avoid traffic. Industry insiders say these aren’t one-off tricks by luxury automakers: The future of cars is connectivity.
