If you're looking for something to read this weekend, here are a couple pieces I've written in the past few days:
1. Epigenetics are cool. Mind-controlling parasites are cool. Epigenetics+mind-controlling parasites=Very cool. That equation is the subject of my latest column for the New York Times.
2. Tomorrow marks the 100th anniversary of the extinction of the passenger pigeon. In honor of that event, I've written a piece for National Geographic News about why its demise still means so much to scientists a century later.
