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.

How soon until we can get robots to tend our gardens?

May 15, 2016

For garden enthusiasts, spring means planting, fertilizing, watering and possibly researching to what extent, and when, to do all of those things. But there’s a growing market of sensors, smart hose attachments, and even robot lawnmowers vying to help you with such chores. These devices and apps can monitor soil temperatures, send you notifications when it’s time to water, and even do the watering for you.

When the watery home of coral gets too warm, the coral expel the microorganisms that live inside and turn white.

These bleached coral aren't dead, but their growth slows tremendously, and they can cease to become the tremendous natural habitats they usually are.

The Great Barrier Reef has recently been hit by a large-scale bleaching event; 93 percent of the corals in the area have been affected, according to a survey by Australia’s National Coral Bleaching Taskforce. But the problem goes beyond Australia.

Our phones hold so much of our personal digital data, so keeping our phones secure is one of the most important personal security measures out there.

How can we build a better password? Smartphones now include fingerprint scanners, and companies have been testing other biometrics — including retinal scans and heart rhythm measurements — for the ultimate personalized "password." But, could “brainprints” be the next unbreakable identification tool?

A team of researchers created a system that could match EEG readings to an individual with, they claim, 100 percent accuracy.
