Why the petri fish? Two reasons.
1) I love bad puns
2) You can now grow synthetic meat straight from a petri dish. Amazing, mind blowing and world-changing. All the things I love about science.
For as long as science is around, I will be fascinated by it. And even more so, by the way we want to use it in society. As a former student of journalism, and now of bioethics, the petri fish combines my two loves, science and writing, in a way that hopefully makes you PONDer (see reason one).
