The new Book of Fungi, by Peter Roberts and Shelley Evans, is a couple of kilograms worth of beautiful mushroom book. The lurid photographs and enticing, offhandedly witty descriptions make the reader want to go out collecting specimens right away -- but the hardcover book's glaring flaw is that, with actual-size glossy pictures of 600 species of fungus, it's hardly a portable companion to the wonders of the woods.
Studies on the impact of wireless radiation on humans are endlesslyinconclusive, but a recent study on the effects of Wi-Fi radiation on trees--yes, trees--indicates that our woody friends may be much more vulnerable than we are.
Nanotech has opened the door to some serious sci-fi possibilities: tiny robots -- built by other tiny robots -- that swim in our bloodstreams eradicating infection or hunting tumors, or perhaps assembling miniscule electronic components. But programming such tiny objects to do what we want presents a problem: commands need space to exist, and space is limited aboard a nanobot. But two papers just published in the journal Nature today highlight an interesting and promising approach to this problem: embedding the commands in the nanobots' environments.
