To sequence the human genome, scientists established a network of laboratories, equipped with robots that could analyze DNA day and night. Once they began to finish up the human genome a few years ago, they began to wonder what species to sequence next. With millions of species to choose from, they could only pick a handful that would give the biggest bang for the buck. Squabbling ensued, with different coalitions of scientists lobbied for different species. Some argued successfully for medically important species, such as the mosquito that carries malaria. Others made the case for chimpanzees, to help them pinpoint that genes that make us uniquely human. And in 2002, a team of scientists made the case for the humble honeybee.

I’ll be speaking on Saturday at the National Association of Science Writers annual meeting in Baltimore. I’ll be discussing how writers can publicize science books in the age of the Internet. It’s a subject I’m still figuring out for myself, so I won’t be dispensing advice so much as sharing thoughts. Details are here.

I’m part of a scienceblogger invasion at the meeting. Matthew Nisbet will be there, talking about reporting on global warming, and Chris Mooney will be speaking about writing about science in new media.

Flowers, flagella, feathers. Life is rife with complex features–structures and systems made up of many interacting parts. National Geographic magazine asked me to take a tour of complexity in life and report on the latest research on how it evolved. What struck me over and over again was how scientists studying everything from bacteria to humans are drawn back to the same concepts–making new copies of old parts, for example, or borrowing parts of one complex trait to evolve a new one. And in each case, complexity opens up the way to diversity, because something many parts can be rearranged in many ways.

This fall we’ve had some rude visitors out by the front door. One morning a strangely foul smell wafted through the windows. When we looked outside for a dead animal, we found nothing. But we noticed some downright obscene growths foisting themselves out of the flower beds. Thus I got my first introduction to the stinkhorn.

Stinkhorns are pornographic mushrooms. They form large underground webs of threads, which feed on dead and dying plant matter. At scattered points in the stinkhorn network, white rubbery spheres grow. Inside each of them is a pre-formed stinkhorn, which can then spring forth.
