  • ...9 more annotations...
  • in the first 100 days of the outbreak tracked closely
  • 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

  • dubbed Rochester, Sutherland, Campanas and Tololo after the sites where the eclipsed star was first detected and analysed
  • similar in mass to our own Sun, but a fraction of its age at just 16 million years.
  • Usually a star’s light is temporarily and periodically dimmed as a planet passes in front of it
  • in this case the team observed an unusually long and deep eclipse with up to 95 percent of the star’s light being dimmed by what the team conclude is a dusty ring system.
  • the only plausible explanation was some sort of dust ring system orbiting a smaller companion
  • Saturn on steroids
  • the first time astronomers have detected an extrasolar ring system transiting a Sun-like star
  • astronomers are unable to conclude what the ring system is orbiting
  • could be a very low-mass star, a brown dwarf, or a gas planet
  • hope to find the answer
  • over the next two years
  • another mystery
  • two pronounced gaps located between rings
  • gaps are carved by moons that have enough mass to gravitationally clear a path along their orbits
  • Saturnian system
  • brown dwarf or star then we could be seeing the late stages of planet formation in action
  • a giant planet, then perhaps there is a moon in the making.
