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

Hr2: Renewable Energy Transition, Speech and Pitch, Max Tegmark

A new study maps out the path for 139 countries to switch entirely to renewable energy sources by 2050. And physicist Max Tegmark contemplates how artificial intelligence could reshape work, justice, and society in the future.

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.
