Science Friday

Science Friday is your trusted source for news and entertaining stories about science. We started as a radio show, created in 1991 by host and executive producer Ira Flatow. Since then, we’ve grown into much more: We produce award-winning digital videos and publish original web content covering everything from octopus camouflage to cooking on Mars. SciFri is brain fun, for curious people.  The radio show is broadcast on many public radio stations Fridays from 2-4 p.m. Eastern Time. You can join the conversation by calling 1-844-724-8255 or tweeting us your questions @scifri.

Flying may be stressful for some people, but planes have it much harder: Every takeoff, landing and patch of turbulence adds wear to a plane’s airframe, or body.

In their findings, published in Proceedings of the National Academy of Sciences, the researchers describe how ancient Rome’s water pipes tell the story of an empire’s rise — and its struggles.
