Ticks are exquisitely sophisticated blood-extracting, pathogen-injecting tools. In the June 2013 issue of Outside Magazine, I give these little beasts their due.

Jason Affourtit writes, “The encircling equation represents biologicalnitrogen fixation, which was at the core of my undergrad/graduate labwork. Working in that research lab (which was originally just part of requirements for med school!–my intended goal) totally changed my focus…So it’s an homage to that period of time, my wonderful advisor, and that lab. DNA has been central to my work life in genomics and has run through as a common theme. So to me, a G-C basepair seemed a natural symbol of that.”

Here is Martha, the last passenger pigeon. She died in 1914 and is now stored at the Smithsonian. Could fragments of DNA from her cadaver--and those of other passenger pigeon--allow us to bring the species back from extinction? I look at the possibility of de-extinction in the April issue of National Geographic.

We’re thrilled to host popular science writer Carl Zimmer for an “Ask X” on the Yale Tumblr!
Here’s how it works:
1) Submit a question via yaleuniversity.tumblr.com/ask.
2) When Carl Zimmer arrives on campus on March 7th to give a talk at the Yale Peabody Museum of Natural History, we’ll kidnap him, pose your questions, and turn the impromptu interview into a YouTube video for your enjoyment.
3) We’ll be choosing only the best 5 - 10 questions to ask him, so make them awesome!
Bio: The New York Times Book Review calls Carl Zimmer “as fine a science essayist as we have.” In his books, essays, articles, and blog posts, Zimmer reports from the frontiers of biology, where scientists are expanding our understanding of life. Zimmer is a member of the Yale College class of 1987, and is a lecturer in the Environmental Studies Program.
