shared by Mars Base on 13 Jan 12 - No Cached
  • Using data from NASA’s Kepler Mission
  • astronomers announced the discovery of two new transiting “circumbinary” planet systems — planets that orbit two stars.
  • two new planets, named Kepler-34 b and Kepler-35 b, are both gaseous Saturn-size planets
  • ...6 more annotations...
  • Kepler-34 b orbits its two sun-like stars every 289 days, and the stars themselves orbit and eclipse each other every 28 days.
  • eclipses allow a very precise determination of the stars
  • Kepler-35 b revolves about a pair of smaller stars (80 and 89 percent of the sun’s mass) every 131 days, and the stars orbit and eclipse one another every 21 days
  • Kepler-34 at 4,900 light-years from Earth
  • Kepler-35 at 5,400 light-years
  • among the most distant planets discovered.

  • data reported from hospital and clinics
  • social media data were available almost instantly
  • others have shown that Twitter and other online sources can provide meaningful information about outbreaks of diseases such as H1N1 and swine flu
  • new work establishes that the approach is useful for tracking a disease that emerges in the unsafe living conditions that often follow a disaster, says Polgreen.
  • 188,819 tweets that contained or were tagged with the word cholera during the first 100 days of the cholera outbreak
  • analysis suggests the social tool provides a good measure of the disease’s spread
  • The researchers compared the tweets to data from HealthMap, a disease-tracking tool that mines Internet news stories, blogs and discussion groups and lets the public report illness by cell phone. Both the Twitter and HealthMap data corresponded to official data from the Haitian Ministry of Public Health.
  • Official sources of data are better validated, but on the downside they are going to take time
