  • But these
  • scientists dominate the research journals, having their names on 41% of all papers.
  • The new research, published on 9 July in PLOS ONE, was led by epidemiologist John Ioannidis of Stanford University in Palo Alto, California, with analysis of Elsevier’s Scopus database by colleagues Kevin Boyack and Richard Klavans at SciTech Strategies
  • ...14 more annotations...
  • They looked at papers published between 1996 and 2011 by 15 million scientists worldwide in many disciplines
  • The ranks of scientists who repeatedly published more than one paper per year thin out dramatically
  • Two or more: 68,221
  • Three or more: 37,953
  • Four or more: 23,342
  • Five or more: 15,464
  • 10 or more: 3269
  • Many of these prolific scientists are likely the heads of laboratories or research groups; they bring in funding, supervise research, and add their names to the numerous papers that result
  • Others may be scientists with enough job security and time to do copious research themselves
  • there’s also a lot of grunt work behind these papers
  • from highly productive labs
  • doctoral students may be enrolled in high numbers, offering a cheap workforce
  • may spend years on research that yields
  • only one or a few papers

  • SpaceX successfully launched six ORBCOMM advanced telecommunications satellites into orbit on Monday, July 14, to significantly upgrade the speed and capacity of their existing data relay network.
  • SpaceX also used this launch opportunity to try and test the reusability of the Falcon 9′s first stage and its landing system while splashing down in the ocean
  • However, the booster did not survive the splashdown. SpaceX CEO Elon Musk reported that the rocket booster reentry, landing burn and leg deployment worked well, the hull of the first stage “lost integrity right after splashdown

  • Musk tweeted. “Detailed review of rocket telemetry needed to tell if due to initial splashdown or subsequent tip over and body slam.”
  • SpaceX wanted to test the “flyback” ability to the rocket, slowing down the descent of the rocket with thrusters and deploying the landing legs for future launches so the first stage can be re-used
  • The previous test of the landing system was successful, but the choppy seas destroyed the stage and prevented recovery
  • the six satellites launched
  • are the first part of what the company hopes will be a 17-satellite constellation. They hope to have all 17 satellites in orbit by the end of the 2014
