    The "Biological Economics" thing is a hyping (or misunderstanding) of the BBC article. The work it refers to seems to be an application of Complex Networks theory to financial networks. I found what appear to be some of the related publications: Andrew G. Haldane (April 2009) Rethinking the financial network (further references in the footnote to page 10) Erlend Nier, Jing Yang, Tanju Yorulmazer and Amadeo Alentorn (April 2008) Network models and financial stability Funny how these issues have been repeatedly popping up at the ACT in recent weeks. This connects both with the discussions on information spreading in networks, and with roadmaps' robustness.

technology radio tracking

shared by pacome delva on 19 Oct 09 - Cached
  • Researchers have discovered that an array of radio transceivers--devices that send and receive signals--can track people's movements behind walls. Possible uses include detecting people trapped in burning buildings, controlling lighting or heating and cooling systems as people enter or exit rooms, and spotting burglars or enemy soldiers.

  • A new study finds support for the "grandmother hypothesis," the idea that older women spread their genes most effectively by helping their daughters take care of their children.
  • Thus paternal grandmothers were most beneficial to the survival of their granddaughters and least beneficial to the survival of their grandsons, while maternal grandmothers showed an intermediate effectiveness. Experts are thrilled by the findings. "Wow, very interesting," says Hawkes. "The consistent results across seven populations ... seem to clarify previously inconsistent results." Lorena Madrigal, an anthropologist at the University of South Florida in Tampa, calls the study "an important contribution to a topic of great interest to evolutionary biologists."

  • By taking a few well-known, readily available measures, researchers argue, Americans could cut their emissions of the greenhouse gas carbon dioxide by as much as 7% over the next decade.

    "climate policy-makers need to pay much more attention to restricting short-lived pollutants, such as methane, carbon monoxide, volatile organic compounds (VOCs) and aerosols. This could create significant changes in the local and global climate quite quickly, whereas the effects of efforts to reduce emissions of long-lived carbon dioxide will not be seen for many years."

    interesting indeed ... but coming at the right time before copenhagn?

    These conclusions come too late to have a real impact on decisions that will be taken in Copenhagen, I assume. But I think it is a hot topic as climate change 'solutions' that work QUICKLY are more and more needed!!

  • 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.

    looking forward to your recommendations how we can get into it quickly :-)

phy nan laser plasmonics

shared by pacome delva on 01 Sep 09 - Cached
  • The nanometer-sized gizmo could provide a key tool for researchers trying to develop a new type of microchip technology called "plasmonics" that mixes electronics and optics.
  • The channel in Zhang's device measures as little as 40 nanometers wide by 5 nanometers high, far smaller than the roughly 250-nanometer diameter of a conventional laser of a similar wavelength.
  • Some physicists and engineers are hoping to build nanocircuits that manipulate plasmonics to marry high-speed electronics and high-speed optics.

    This is about biological and technical hygromorphs, i.e. structures that change shape according to humidity. Next to pine cones, there is also a cool study on wheat awns which drill themselves into the soil just by daily variance of air humidity. Biomimetics would be passively controlled acutators or humidity driven valves in space station to open/close dehumidification devices.

    Interesting, but only an abstract... do you have the full paper ?
  • Tobias Seidl on 12 Jul 09
     
    Not yet. There is also some other nice mechanism of wheat awns and how they use changes in humidity to anchor in soil. Would maybe fit with the above mentioned work of oisin.
