Submission + - Could crowd-sourced democracy be made to work? (google.com) 1

maccallr writes: The Occupy Movement is getting everyone talking about how to fix the world's economic (and social, environmental...) problems. It is even trialling new forms of "open" democracy. Trouble is, it's easy to criticise the physical occupiers for being unrepresentative of the general population — and much of their debating time is spent on practical rather than policy issues. Well-meaning but naive occupiers could be susceptible to exploitation by the political establishment and vested interests. In the UK, virtual occupiers are using Google Moderator to propose and debate policy in the comfort of their homes (where, presumably, it is easier to find out stuff you didn't know). Could something like this be done on a massive scale (national or global) to reach consensus on what needs to be done? How do you maximise participation by "normal folk" on complex issues? What level of participation could be considered quorate? How do you deal with block votes? What can we learn from e-petitions and Iceland's crowd-sourced constitution? Is the "Occupy" branding appropriate? What other pitfalls are there? Or are existing models of democracy and dictatorship fit for purpose?

Submission + - Google Maps, Disease Risk, and Migration (stanford.edu)

ecorona writes: This google maps mashup http://geneworld.stanford.edu/hgdp was published in Science this week. Paywall warning: http://www.sciencemag.org/content/334/6056/583.full. It shows genetic risk for multiple diseases distributed across the globe. It's easy to follow the migration path and see which diseases increase/decrease in risk along human migration paths. Click on the populations to see the relative risk of the selected disease for each population. You can pick your a disease and see which populations are more susceptible. The article is behind a paywall, but the website is free to use.

Submission + - First Exoplanet Discovered Orbiting Two Stars (discovery.com)

astroengine writes: "For the first time, astronomers have discovered an exoplanet orbiting binary stars. Kepler-16b, a Saturn-sized world approximately 200 light-years away, orbits Kepler-16, two stars locked in a mutual dance. Although other exoplanets are known to exist in binary systems, they have only been known to be orbiting one star of the binary pair; Kepler-16b orbits both.

"It shows the gears of celestial mechanics turning and interlocking so vividly, you almost want to reach out and touch it," exoplanet scientist Marc Kuchner, with NASA's Goddard Space Flight Center in Greenbelt, Md., told Discovery News. "Kepler himself would have been dizzy with excitement."

No doubt Kepler-16b will excite memories of Tatooine, Luke Skywalker's homeworld, but the double sunset is where the similarities end. Kepler-16b would be anything but a desert world; it is the approximate size of Saturn, it is extremely cold, and is the average density of water."
