Science Friday

Science Friday with host Ira Flatow discusses the latest in science, technology, health, and the environment. It's brain fun, for curious people.

Recent Episodes

Hr1: News Roundup, 13 Reasons, Volcanoes, Fake Flavors

Researchers are using magma trapped in crystal structures to study the life beneath volcanoes. Plus, modern fake flavors owe more to the chemistry of the past than their real fruit counterparts.

Hr2: FDA Fast Track, Evolution, Solar Eclipse App for Visually Impaired

Researchers say fast-tracked drugs are not being rigorously tested after the approval process. Plus, modern evolutionary science has some advantages Darwin did not. What are we learning from DNA, experimentation, and more? And how researchers are using sound and vibrations to describe the eclipse to visually impaired viewers.

Hr1: News Roundup, Oroville Dam, Biometrics, Sweat

Fingerprint scanners are standard on new smartphones, and new ID methods are on the way. But security researchers say biometrics are still too easily duped. Plus, how humans and other animals have evolved to beat the heat.

Hr2: Lunar Magetism, Curiosity, Eclipse Balloons

Curiosity drives much of our learning and creativity. Where do we get it from, and how does it change our brains? Plus, the NASA Eclipse Ballooning Project hopes to livestream the solar eclipse from weather balloons across the country. And scientists still do not know when or why the moon lost its magnetic field, but it was at least a billion years later than they thought.

Hr2: Gene Editing, Voting Machine Hacks, Neutrinos, Midnight Scan Club

Researchers can fix genetic mutations in human embryos. But should they? Plus, physicists were able to take the first measurement of a neutrino interacting with the nucleus of an atom. And a look at what security is in place to protect voter registration databases and voting machines.
