Ep 28: Interview with Dr. Ilana Brito on microbiomes; Ithaca celebrates "Darwin Days" and more...

In this week’s show, Gina Mason reports from Darwin’s Trivia Challenge held earlier this week as part the Darwin Days, in honor of Darwin’s 209th birthday.

And, Esther Racoosin talks with Cornell’s Ilana Brito about the dizzying diversity of bacteria, viruses and other tiny organisms that make their home inside our guts. Dr. Brito will discuss how those microbes got there in the first place, how they evolve and what that means for our health.

You’ll also hear about upcoming science events, and take a look back through time at science discoveries past, in the segment: This week in science history.
