When it comes to viruses, we humans like to pretend we know much more than we really do. It’s understandable. The influenza virus, for example, has only ten genes. It is just a shell that delivers genes and proteins into a host cell, where it hacks the biochemistry to manufacture more viruses. It seems like such an easy biological problem to solve.

Yet the flu and other viruses hide a complexity which virologists have only partly uncovered. The idea that someone could intentionally design a super-lethal virus from scratch–as plausible as it may seem–is, for now, a delusion.

In January, I’ll be conducting the 2012 edition of my science writing workshop for graduate students. The workshop is hosted by the Yale Ecology and Evolutionary Biology Department. It’s a short introduction to the craft of bringing science to the world, tailored for science graduate students. People who attend are typically interested in making science writing part of their work as scientists, or are even thinking about making it their career. Students from other institutions can contact the EEB department to get permission to register.

The syllabus and information about registering are on the workshop web site.

The New York Times has launched a series called Profiles in Science. When I was invited to join the undertaking, I proposed writing about the Harvard psychologist Steven Pinker. I had run into Pinker at the World Science Festival in June, and he had told me about his next book, The Better Angels of Our Nature, which was due out in the fall. In the 800+ page tome, Pinker argues that rates of human violence have been crashing for millennia, and he offers psychological explanations for the fall.

We know that our species is unique, but it can be surprisingly hard to pinpoint what exactly makes us so. The fact that we have DNA is not much of a mark of distinction. Several million other species have it too. Hair sets us apart from plants and mushrooms and reptiles, but several thousand other mammals are hairy, too. Walking upright is certainly unusual, but it doesn’t sever us from the animal kingdom. Birds can walk on two legs, after all, and their dinosaur ancestors were walking bipedally 200 million years ago. Our own bipedalism–like much of the rest of our biology–has deep roots. Chimpanzees, whose ancestors diverged from our own some seven million years ago, can walk upright, at least for short distances.
