I’ve just discovered an online game called Killer Flu, presented by the UK Clinical Virology Network. I’ve been fairly leery of video games that try to present science in the past, because they either skimp on the science or skimp on the game. Killer Flu seems, on first inspection, to get fairly close to the happy medium.

You have to get a flu outbreak going in three months by infecting as many people as you can. There are lots of challenges, such as tough immune systems, and special tricks, such as infecting people who are likely to infect lots of other people. The game is bogged down by a few big blocks of text that pop up to explain how the flu virus spreads–something that a few paragraph breaks or separate windows could take care of easily. But those drawbacks are more than compensated by the elegant, SimCity like interface.

I’m curious what living, breathing virologists and epidemiologists think of it. All I know is that I am going to try to avoid this web site, because I have a lot of work to do today. And for me, that’s as high a compliment as I can pay to a game.

Beyond three billion years ago, the fossil record of life on Earth gets very patchy. At 3.4 billion years ago, there’s fairly good evidence of mats of microbes. At 3.5 billion years, there are little globules that have been proposed to be bacteria but which some researchers consider just blogs blobs of minerals. Earlier still there are shadowy isotopic hints–ratios of light and heavy carbon atoms that seem biological rather than volcanic–dating back as far as 3.8 billion years. These, too, are the subject of great debate. And before that, nothing. Seven hundred million years of nothing.

The earth’s climate has, of course, fluctuated frequently — and at times wildly — over hundreds of millions of years, long before humans began pouring heat-trapping gases into the atmosphere. So why the concern over the current surge of warming, brought about largely by human activity? Anthony Barnosky, a University of California, Berkeley, scientist who has studied previous eras of climate change, succinctly sums up the problem: Too much warming, too fast.

Today I’ve got an interview posted over at Yale Environment 360 with Tony Barnosky, a paleontologist who’s just written a very interesting book called Heatstroke: Nature in an Age of Global Warming. He gazes into a fossiliferous crystal ball to get an idea of what global warming will do to the world’s biodiversity. Short answer: it won’t be pretty.
