It was a busy week on the shameless self-promotion front. I chatted with Sonali Kolhatkar of Uprising Rradio (KPFK) about my book, Me, Myself and Why -- there's even video. I can also be heard on the latest episode of Science for the People podcast, hosted by Desiree Schell, along with Ed Yong, who enlightened us on the nuances of research into oxytocin. And if you're keen to hear me yammer on some more about science of self, you can catch me on WGBH's Innovation Hub (airs Saturday 10 AM Eastern).

If you missed this past week's Cosmos, here's my recap: Getting a fix on Earth's age, and the danger of lead. Related: Patterson and Kehoe, and the great lead debate.

Bonus: What the World Actually Looked Like on the Day Creationists Say It All Began.

Of course, a lot more happened this week that had nothing to do with me (or myself). We bid farewell to LADEE, the NASA spacecraft that crashed into the moon this week. "The vending-machine-sized spacecraft ran out of fuel and collided with the moon at a speed of roughly 3,600 miles per hour.... The doomed satellite encountered so much heat -- hundreds of degrees -- that as it broke up during impact, parts of it may have even vaporized."
