You may have read not long ago about birds that can plan for the future. The occasion was a paper that came out in the journal Nature detailing some experiments on scrub jays. I found the paper fascinating, not just for the results themselves, but for the many other studies on mental time travel that are going on these days dealing with other animals–rats, pigeons, monkeys, and us. Instead of simply reporting on one experiment, I took some extra time and took a survey of the past and future of mental time travel. It appears in tomorrow’s New York Times.

There’s nothing more grating for a science writer than see your work get cut and pasted to give people precisely the wrong impression. My latest irritation: “Ten Questions For Al Gore and the Global Warming Crowd”, which appeared Friday on the conservative web site Townhall.com.
The author is John Hawkins, who describes himself as a professional blogger who runs Right Wing News. Hawkins claims that he is skeptical that humans are causing global warming because, in his words, “‘the Earth-is-going-to-burn-us-alive’ crowd cannot answer the most basic questions about the theory that they haughtily insist is so beyond reproach that there should be no more need for debate.”
Before I head for Utah, let me direct your attention to two articles of mine in tomorrow’s New York Times. They don’t have a whole lot in common except they are examples of cool biology…
1. Virus traps. Here’s a case where ecology, evolution, and medicine all come together in an intriguing mix. You can think of any population of animals, plants, or other organisms as a leaky bucket under a running faucet. The population is boosted by sources of new individuals, and drained by sinks. Sources may include rapidly reproducing individuals, or immigrants from other populations. Sinks include the death of individuals in the population, or their failure to reproduce.

Scientists often stick genes into organism in order to create something new. Remote-controlled flies, for example, or photographic E. coli. But by creating new kinds of life, scientists can also learn about the history of life. Give a mouse human vision, for example, and you may learn something important about how our own eyes evolved.
As mammals go, we have unusual eyes. Most mammals produce two kinds of pigments for catching light. One is sensitive to short wavelength light (at the blue end of the spectrum). The other is sensitive to a longer wavelength, in the green or red part of the spectrum.
Next week I’ll be heading to Utah. Southern Utah University asked me to be their Visiting Eccles Scholar, which means that I’ll be spending a couple days talking with students and faculty. I’ll also be giving two talks that are open to the public. The first, Wednesday evening, will be on global warming and extinctions, about which I wrote an article for the New York Times a couple months back. The next evening I’ll be talking about E. coli and the meaning of life. It’s the first time I’ll be speaking about my book in public, so I’m looking forward to sharing some of the stuff I learned while writing it. So if you’re anywhere in the vicinity of Cedar City, come on out.
