How Many Triangles Are There? Here’s How to Solve the Puzzle

A couple of weeks ago, I wrote about a viral math problem — 8÷2(2+2) = ? — that drew the disdain of many mathematicians because it contained little actual math.

The Thick Gray Line: Forest Elephants Defend Against Climate Change

Why Sexually Transmitted Infections Can’t Shake Their Stigma

As an obstetrician and gynecologist, I get a lot of panicked calls and direct messages on social media — sometimes from acquaintances, sometimes from complete strangers — about gynecological matters.
