Walk into a pre-school or elementary school today and you won't find peanut butter, but you'll likely see a few sets of twins ...we'll look at twinning patterns throughout human history, and why the proportion of twins in the population continues to ebb and flow.
And conservation by drone - we'll hear about a program designed to save black-footed ferrets from the plague by air-dropping vaccines.
The Twin Boom
Walk into a pre-school or elementary school today and you won't find peanut butter, but you'll likely see a few sets of twins. The US and the entire world are in the midst of a twin boom - a phenomenon last seen in the west after World War I.

Laura Spinney is a writer and science journalist, based in Paris. She wrote about the "twin boom" for Aeon.

In this piece from Radio Rookies, she questions one of their decisions - not to teach her their language.
