Tetris, North Korea, health care, and PS3s.

Tetris makes you smrtr! It increases brain efficiency, but I think the point of the research is brain stimulation, not Tetris versus other forms of stimulation.

North Korea being relatively conciliatory? Another try at a peace treaty, but I don't think they can backpedal fast enough.

A neat video on the need for universal health insurance.

Almost three-quarters of PS3 owners have seen at least one blu-ray. That seems low to me, actually.
