More watchy goodness, mostly courtesy of TED:

Rebecca Saxe: How we read each other’s minds – actually about the  business of making accurate, predictive models of each other’s minds in our own. They’ve localised the ability to a particular segment of the brain, the Right Temporo-Parietal Junction (RTPJ) – verified by manipulating it to vary people’s capacity to understand what’s going on for each other. Quite literally mind-boggling, in several senses; very scary; and absolutely must-watch if you’re at all interested in the ways we relate to each other. I’d be fascinated to know if there is any gender-differentiation between men and women in the development of the RTPJ – and whether there’s any observable difference at birth, given the current state of gender neuroscience which seems to say that the differences between male and female brains in infancy are very few indeed.

Susan Blackmore on memes and “temes” – there’s a lot she doesn’t cover properly, like the changing nature of the medium of mimesis across her three generations of replicators and its implications. (I’m still chewing this over but there may be a post on it at some point.) But with only 20 minutes you can’t blame her – she’s using her time well.

Jane McGonigal: Gaming can make a better world – it can, and it should, but I don’t believe it will while the institutions that control the vast majority of culture-generation resources are beholden primarily if not exclusively to their own bottom line. But it’s inspiring to see someone thinking about ways to redivert all that focus, energy and creativity back into a world that needs it so badly.

And just for fun, because cute+ingenious is always a winning combo:
