In Turkey, when authoritarianism took hold, satire was one of the first casualties. Political comedy shows disappeared—now, airing one could land you in jail.

For many years while I was running a scientific skepticism site/podcast I repeated the mantra "vaccines were so successful, we forgot their impact due to vanishing diseases."
Bringing a major pseudoscience conspiracist in charge of HHS is a sure way to remember their impact- in the most painful way.

Having missed last week's $10K treasure hunt, I decided to hunt for another treasure myself this weekend: the Tiburon Mariposa Lily, which grows only in Tiburon and nowhere else in the world. ONLY in the Ring Mountain Preserve in Tiburon. So I headed there yesterday to try my luck. 1/n
