Tasha Sturm, a lab tech, sampled her 8 year old son's hand when he came in from playing outside in an agar medium, then cultured the microbes that came off in the dish. Read the rest
A great, full-body-squick-inducing article in National Geographic provides an overview of the current research on parasites that use a combination of techniques to control their hosts' behavior, making them sacrifice themselves for the sake of the parasites and their offspring. Read the rest

Wagner James Au sez, "Created by virtual world/avatar pioneer Jeffrey Ventrella, Wiglets are self-animated, augmented reality creatures for mobile devices powered by an open source AI system, and have genomes that are stored in the cloud along with their geo-locations. 'This means they can exist in specific locations in the real world,' Jeffrey explains. The overall goal with Wiglets is to encourage kids to find/play with their creatures in the natural world."

Science fiction writer and biologist Peter Watts gave a spectacular talk to the Symposium of the International Association of Privacy Professional, called The Scorched Earth Society: A Suicide Bomber's Guide to Online Privacy (PDF); Watts draws on his two disciplines to produce a stirring, darkly comic picture of the psychological toll of the surveillance society.

I only wish I'd been in the room to give the talk, as he's a remarkable and acerbic storyteller. Read the rest
