    nice paper: like especially: To our knowledge, our model provides the first unified explanation of high-frequency, intra-conflict data across human insurgencies. Other explanations of human insurgency are possible, though any competing theory would also need to replicate the results of Figs 1, 2, 3. Our model's specific mechanisms challenge traditional ideas of insurgency based on rigid hierarchies and networks, whereas its striking similarity to multi-agent financial market models24, 25, 26 hints at a possible link between collective human dynamics in violent and non-violent settings1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19.

  • To try to explain the mechanism behind these patterns, the team borrowed a simple computer model from economics. The model treated all insurgencies like a marketplace--groups of people constantly deciding whether to act. Rather than coordinating, the groups simply watch the news. The size of the carnage reported at any given time determines the probability that a group of a given size will strike next. Like clockwork, the attacks over the course of the conflict--from the smallest to the most deadly--have the same distribution.

  • One of the quasar's jets is aimed directly at the galaxy, and the team thinks it's likely that the jet is driving the star-making process by blasting matter into the galaxy.
  • The discovery creates a new picture of galaxy formation

  • Even the folks at LeapFrog caution that electronic toys shouldn’t replace the tried-and-true childhood staples of previous generations. Plain old wooden blocks can be an incredibly valuable learning tool, says Jim Gray, a former child development researcher who now heads the learning team at LeapFrog.

  • The event is just one of dozens this weekend being promoted by the Sunlight Foundation as part of its Great American Hackathon. Each one is being organized by volunteers who want to make government data easier to access and more useful to the public. In Pittsburgh, the hackers will be working on making stimulus spending easier to understand. In Boston, the Massachusetts Department of Transportation data will be the focus.

    very interesting study. Although it is not so much a surprise, they cite many papers on planetary formation that predicted this, and the only paper on degassing they cite is from our rather unpopular french ex-minister of research c. allegre, who refuses the fact that humans have an impact on climate...
