  • Hi listeners, I'm Jeff Del Vicio,

  • the chief multimedia editor and executive producer here at Scientific American.

  • I work every day alongside Rachel and Fonda and the rest of our crew here at Cyan to bring you science quickly.

  • But before we dive into today's episode, I want to share something very personal and important.

  • I spent the last 25 years of my life telling stories about science.

  • I've written, filmed, recorded, and animated the discoveries that shape our world.

  • Whether it's exploring science inside of biosafety labs or out on ice sheets,

  • I've witnessed the power of science journalism.

  • But here's the hard truth.

  • Journalism like ours is getting harder to do.

  • Newsrooms are shrinking, misinformation is growing, and responsible reporting,

  • real, verified human reporting, takes time, care, and support.

  • Subscribing to Scientific American is the best way to keep science journalism alive.

  • As Thomas Jefferson once said,

  • if a nation expects to be ignorant and free in the state of civilization,

  • it expects what it never was, never will be.

  • I know we all want to live free, so let's keep learning together.

  • For Scientific American Science Quickly, I'm Rachel Seltman.
