Roland Piquepaille writes "A Stanford University team has developed a microscope weighing only 1.1 grams. It is so small that it can be mounted to the head of a freely moving mouse to watch its brain cell activity. According to what the lead researcher told New Scientist, 'A lot of work has been done using brain slices, or anaesthetised animals — even using animals that are awake but restrained. But so far it has been impossible to image cellular-level activity in a freely moving mouse.' Not any more. And as mice are the 'preferred' animals in medical labs, this new kind of microscope could lead to new ways to study human diseases."

Last weekend the dark horde of nerddom descended on Seattle, entering the heart of the 'Emerald City' to gorge itself on the music, culture, and humor of gaming. The Penny Arcade Expo (PAX) once again brought together fans of the influential webcomic for a festival that, without even trying, seems to be taking the place of old E3. Though they were expecting around 30,000 people, the word was that by early Sunday they'd already gone through some 40,000 badges. There were DSes everywhere, concerts at night, a packed exhibit hall, and benchmark comic strips created by Mike Krahulik and Jerry Holkins adorned almost every wall. Despite all the people and the noise, somehow the event had a community feel to it that was hard to understand ... and even harder to describe. I'll try, though, along with impressions from games on the show floor and the incredible music of folks like Jonathan Coulton and the Minibosses. Read on, and All Hail Ball.
