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.
