AMS Policy Statement on Geoengineering the Climate System - 0 views

  • Therefore, the American Meteorological Society recommends:
  • Enhanced research on the scientific and technological potential for geoengineering
  • the climate system, including research on intended and unintended environmental responses.
  • ...2 more annotations...
  • Coordinated study of historical, ethical, legal, and social implications of geoengineering
  • that integrates international, interdisciplinary, and intergenerational issues and perspectives and includes lessons from past efforts to modify weather and climate. Development and analysis of policy options to promote transparency and international cooperation in exploring geoengineering options along with restrictions on reckless efforts to manipulate the climate system.

    policy statement regarding research on geoengineerin in the US (in force from July 2009-July 2012)
  •  
    looking forward to your recommendations how we can get into it quickly :-)

Revealing the Universe: the Hubble Extreme Deep Field | Bad Astronomy | Discover Magazine - 1 views

  •  
    Astronomers using the Hubble Space Telescope have created the deepest multi-color* image of the Universe ever taken: the Hubble Extreme Deep Field, a mind-blowing glimpse into the vast stretches of our cosmos.

Indoor clouds - 4 views

  •  
    created by a Dutch artist :)
  •  
    Any idea how?
  •  
    It seems like he just recreates in the room the right combination of temperature and humidity and than with a fog machine he generates the cloud ... I thought he could be a nice candidate for the artist in residence :)

New structures self-assemble in synchronized dance - 3 views

  •  
    With self-assembly guiding the steps and synchronization providing the rhythm, a new class of materials forms dynamic, moving structures in an intricate dance. Researchers have demonstrated tiny spheres that synchronize their movements as they self-assemble into a spinning microtube.
  •  
    This is quite similar to the following paper. Here they show how tiny variations of particle parameters can produce clearly distinct structures: Thermal and Athermal Swarms of Self-Propelled Particles --> http://arxiv.org/abs/1201.0180

In super-earths magnesium oxide may be metallic and sustain magnetic fields... - 1 views

  •  
    The mantles of Earth and other rocky planets are rich in magnesium and oxygen. Due to its simplicity, the mineral magnesium oxide is a good model for studying the nature of planetary interiors. New work studied how magnesium oxide behaves under the extreme conditions deep within planets and found evidence that alters our understanding of planetary evolution.
