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.

In the future, people might really wear their emotions on their sleeves

Picking up on subtle cues in our conversations with other people is tough — and it can be even trickier for people with social anxiety or Asperger’s syndrome.

In 2015, after much public debate, the Federal Communications Commission passed rules mandating net neutrality — the idea that all data should be treated equally by internet service providers. The rules labeled broadband internet a utility under Title II of the Telecommunications Act.

Lithium-ion batteries power everything from our laptops to phones to electric vehicles, but they’re far from perfect. In fact, they were the culprits behind Samsung’s recent exploding Galaxy Note 7 phones. 

“The word ‘bomb’ is not out of place here,” says David Pogue, tech columnist for Yahoo Finance and the host of NOVA’s documentary “The Search for the Super Battery.”

Scientists make a battery that runs on stomach acid

A new wave of “ingestible electronics” is poised to transform health care from the inside out. Researchers are experimenting with sensors that can wirelessly monitor vital signs like heart rate, respiratory rate and body temperature from the squishy interior of our gastrointestinal tract.

Should artificial intelligence be used in science publishing?

Feb 28, 2017

Advances in automation technology mean that robots and artificial intelligence programs are capable of performing an ever-greater share of our work, including collecting and analyzing data. For many people, automated colleagues are still just office chatter, not reality, but the technology is already disrupting industries once thought to be just for humans. Case in point: science publishing.

In 2014, the city of Flint, Michigan changed the source of its water from the city of Detroit to the Flint River. But in the transition to river water, officials didn’t implement proper anti-corrosion measures. Lead leached from old pipes into the water supply, and in some homes, lead levels measured 10 times higher than the limit set by the Environmental Protection Agency.

Last month, lead levels in Flint's city water finally tested below federal-action level. But residents are still being cautioned to use filters on their faucets, or to drink bottled water.

Harvard researchers say they’ve created metallic hydrogen

Feb 25, 2017

Hydrogen is the most abundant element in the universe — and we know it mainly as a gas, not a metal. But in 1935, the physicists Eugene Wigner and Hillard Bell Huntington theorized that under high enough pressures, hydrogen could actually become metallic.

Since then, scientists have tried all sorts of techniques to create metallic hydrogen. Now, reporting in the journal Science, researchers at Harvard University say they’ve squeezed hydrogen between two diamonds — and made metal happen.
