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.

To participate, call 1 (844) 724-8255 or Twitter users can tweet questions @scifri.

Science in the Crosshairs

It’s easy to see why the fungus Xylaria polymorpha might spook someone.

Is 'last-chance tourism' good or bad for endangered places?

When you hear that some extraordinary place is undergoing big changes, it’s a natural impulse to want to get out and see it.

The glaciers are retreating in Glacier National Park? Time to finally take your kids to hike them — or for a swim through kaleidoscopic coral at the Great Barrier Reef, which is threatened by bleaching.

Our visits to endangered sites can feel a bit like paying respects — but are they any good for the sites themselves?

Redwoods and fog: a love story

California’s towering redwood trees are iconic symbols of its coastline — and so is the low, rolling fog that often blankets Route 1. And as it turns out, the two are linked in more than just imagery: The fog plays an important role in keeping the redwoods hydrated and healthy. It’s also giving us clues about how the trees might respond to more drastic climate changes.

Scientists try to save this frog species from being wiped out by fungus

The mountain yellow-legged frog lives high in the remote alpine lakes of California’s Sierra Nevada range, but its population is being decimated by a microscopic, global scourge.

This disease, known as chytrid fungus, irritates the frogs' skin, and causes it to slough off. It can be deadly, as amphibians' outer layer helps them to absorb nutrients and breathe underwater. In recent years, the spread of chytrid fungus has devastated hundreds of amphibian species worldwide.

You've probably heard fitness experts say that 10,000 steps — about 5 miles — should be your goal if you want to reap the daily benefits of exercise. And if your desk job makes a pedometer routine tough to keep, one of your co-workers may have already recommended you try out a standing desk.

Both the 10,000 steps adage and the standing desk are popular additions to modern fitness regimens, but have you ever wondered why? As it turns out, both are probably better for you than sitting in a cubicle, but neither is completely backed by cold, hard science.
