Here, for your viewing pleasure, is a very important part of a very special flu virus. It may look like an ordinary protein, but in fact it’s been at the center of a blazing debate about whether our increasing power to experiment on life could lead to a disaster. Not that long ago, in fact, a national security advisory board didn’t even want you to see this. So feast your eyes.

For those who are new to this story let me start back at the beginning, in 1997.

In the May issue of National Geographic, I contemplate the hand. Human hands are unique and versatile–and yet we are far from the only animals with them. By looking at the variety of hands in nature, we can see some of the most striking evidence of how evolution tinkers in all sorts of unexpected way. Check it out.

The print version is accompanied by lovely sketches of a wide range of hands. If you read the story online, you can see an animation of the human hand. And if you have the National Geographic iPad app, you can see videos of other hands, from frogs to aye-ayes.

I’m heading south to give a series of talks about everything from evolution to science tattoos, the future of journalism, and the mutant bird flu saga. Most of these talks are open to the public. Here’s the rundown, with the public talks noted:

If there’s ever excuse to publish an optical illusion as cool as the “Rotating Snakes,” I’ll take it. This illusion was invented in 2003 by Akiyoshi Kitaoka of Ritsumeikan University in Japan, and ever since, Kitaoka and other scientists have been trying to figure out why it works. A new paper by Stephen Macknik at the Barrow Neurological Institute in Phoenix may have the answer.

As you’ll notice, the circles seem to rotate in response to where you look at the illusion. So Macknik and his colleagues tracked the movement of people’s eyes as they gazed at two of these wheels on a computer screen. Their subjects kept a finger pressed on a button, lifting it whenever they seemed to see the wheels move.

I got back home last night to a pleasant surprise: a copy of the new French translation of The Tangled Bank: An Introduction to Evolution. One of the most interesting parts of writing a book is seeing what emerges from the mind of your translator. I’ve usually had good luck with translators. We’ll exchange emails to find a way to capture the spirit of sentences in my books that would make no sense in another language, thanks to the odd figures of speech we use in English. When the book actually arrives, I usually can do little more than hope that it makes sense in Korean or Japanese or Dutch.
