Science’s Breakthrough of the Year, our best online news, and science books for your shopping list

Dave Grimm—online news editor for Science—talks with Sarah Crespi about a few of this year’s top stories from our online news site, like ones on a major error in the monarch butterfly biological record and using massive balloons to build tunnels, and why they were chosen. Hint: It’s not just the stats.

Sarah also interviews Staff Writer Adrian Cho about the 2017 Breakthrough of the Year. Adrian talks about why Science gave the nod to the Laser Interferometer Gravitational-Wave Observatory team for a second year in a row—for the detection of a pair of merging neutron stars.

Jen Golbeck is also back for the last book review segment of the year. She talks with Sarah about her first year on the show, her favorite books, what we should have covered, and some suggestions for books as gifts.
