  • Triple F-a comet nucleus sample return mission

    • The Triple F (Fresh From the Fridge) mission, a Comet Nucleus Sample Return, has been proposed to ESA's Cosmic Vision program. A sample return from a comet enables us to reach the ultimate goal of cometary research. Since comets are the least processed bodies in the solar system, the proposal goes far beyond cometary science topics (like the explanation of cometary activity) and delivers invaluable information about the formation of the solar system and the interstellar molecular cloud from which it formed. The proposed mission would extract three sample cores of the upper 50 cm from three locations on a cometary nucleus and return them cooled to Earth for analysis in the laboratory. The simple mission concept with a touch-and-go sampling by a single spacecraft was proposed as an M-class mission in collaboration with the Russian space agency ROSCOSMOS.

  • National differences in gender-science stereotypes predict national sex differences in science and math achievement
  • 2009
  • Ingår i: Proceedings of the National Academy of Sciences of the United States of America. - : Proceedings of the National Academy of Sciences. - 0027-8424 .- 1091-6490. ; 106:26, s. 10593-10597
  • Tidskriftsartikel (refereegranskat)abstract
    • About 70% of more than half a million Implicit Association Tests   completed by citizens of 34 countries revealed expected implicit   stereotypes associating science with males more than with females. We   discovered that nation-level implicit stereotypes predicted   nation-level sex differences in 8th-grade science and mathematics   achievement. Self-reported stereotypes did not provide additional  predictive validity of the achievement gap. We suggest that implicit stereotypes and sex differences in science participation and   performance are mutually reinforcing, contributing to the persistent   gender gap in science engagement.
