A bioterror attack in World of Warcraft
In the Harry Potter universe, how precisely does one become a wizard? Well, if you’ve read the J. K. Rowling books, you’ll know that the world is divided into magical peoples — wizards and witches — and normal, unmagical ones, the muggles. A wizard or witch can be born from two magical parents, two muggles, or a mixture thereof — a half-blood.
This got a couple of genetic scientists in Britain wondering: What are the chromosonal implications here? They quickly set pen to paper and produced one of the more curious letters that has ever appeared in Nature: A Darwinian explanation of the Harry Potter’s inheritance of magical abilities. To quote:
This suggests that wizarding ability is inherited in a mendelian fashion, with the wizard allele (W) being recessive to the muggle allele (M). According to this hypothesis, all wizards and witches therefore have two copies of the wizard allele (WW). Harry’s friends Ron Weasley and Neville Longbottom and his arch-enemy Draco Malfoy are ‘pure-blood’ wizards: WW with WW ancestors for generations back. Harry’s friend Hermione is a powerful muggle-born witch (WW with WM parents). Their classmate Seamus is a half-blood wizard, the son of a witch and a muggle (WW with one WW and one WM parent). Harry (WW with WW parents) is not considered a pure-blood, as his mother was muggle-born.
There may even be examples of incomplete penetrance (Neville has poor wizarding skills) and possible mutations or questionable paternity: Filch, the caretaker, is a ‘squib’, someone born into a wizarding family but with no wizarding powers of their own.
Cool enough. But even better is that three other scientists immediately dashed off a following letter that disputed the theory. Noting that “Hermoine’s parents were muggle dentists who lack any family history of wizarding,” they find “the assumption that wizarding has a genetic basis to be deterministic and unsupported by available evidence.”
Finer tongue-in-cheek science cannot be had. Though they weren’t merely being witty. The original scientists wrote their Nature letter as a “teachable moment”: They noted that since genetics are difficult to teach to young children, Potter’s universe offered a unique opportunity for science teachers to talk about DNA and inheritance. But this also, of course, implies the teaching of evolution, which makes you wonder which will be the bigger reason for the evangelical right to hate J. K. Rowling: Because she’s indoctrinating kids in witchcraft — or in Darwinian science?

My Xbox broke, and I was trying to Google some possible technical solutions, when I noticed that Google appears to be encouraging me to make a typo. I suppose it’s possible that Google’s algorithms know that typing “wont” instead of “won’t” would produce better results.

On the other hand, when I tried the test for multitasking, I was pretty abysmal. I performed worse than people who identify themselves as heavy multitaskers, and those who identify as low multitaskers.

I finally got around to trying out the interactive “test your distractability and multitasking” page at the New York Times, which they put up alongside their story earlier this month about how computer distractions are eroding our lives.
According to the test, I guess I have good focus — I’m not very distractable!
