Steve Mould's colored flashlights (sometimes called "coloured torches" in distant lands) are useful props in this excellent 5-minute lecture on color mixing. I learned that magenta is not a color. Rather, it is the absence of green.
Experimental psychologists find that humans prefer explanations for events that have certainty and a sense of purpose over undirected randomness. Read the rest
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
Mammal penises, including those of cetaceans, are pretty easy to find, while vaginas are more difficult to examine; historically, accounts of animal reproduction have emphasized the features of penises and theories of sperm competition, but a burgeoning scientific emphasis on whale vaginas is revealing structures and strategies that are amazing and wonderful.

There are some pretty freakish, but well-substantiated, reports this week that demonstrate just how much we still have to learn about stem cells and how they work (and don't work). 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."
$65 gets you the book and a virtual Wiglet. Read the rest
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.
Watts is the writer who was beaten, maced, and convicted of a felony for asking a US border guard why he'd walked up behind his rental car and opened his trunk without any discussion or notice. His take on surveillance and its relationship to control, authoritarianism and corruption is both sharp-edged and nuanced. And his proposal for a remedy is provocative and difficult to argue with. I only wish I'd been in the room to give the talk, as he's a remarkable and acerbic storyteller. Read the rest
A scientist in Florida who studies simple sea animals known as comb jellies says he has discovered a path to a new form of brain development that may one day lead to treatments for Parkinson's, Alzheimer's and other neurodegenerative diseases. Read the rest
