    Colombia Brings Libraries to the Park

    Via Bilingual Librarian:

    Monday morning I was out walking around downtown Bogota when I happened upon this lovely little library in the park. This stand makes part of the Paradero Para Libros Para Parques (PPP), a program created about 10 years ago to help promote literacy across the country. The program is part of Fundalectura in association with city parks.

    Currently there are 47 PPP in various neighborhoods of Bogota, and a total of 100 across the country. Each stand is staffed for about 12 hours a week by volunteer (they do receive a small stipend, but apparently it isn’t much).

    The PPP are often open during the weekend and while in service they offer regular library services. Patrons can check books out, and the person staffing the PPP organizes activities (mainly for children), is available to answer questions, and often help children with their homework.

      Model Realistically Simulates Plate Tectonics

      ETH Zurich scientists have for the first time succeeded in realistically simulating how an oceanic plate sinks of its own accord under an adjacent plate. At the same time they showed why only one of the plates rather than both subducts into the Earth’s mantle, and how this process affects the dynamics of the Earth’s interior.

        We haven’t really been following tumblr enough to know if this story exploded here already, but it’s important enough that we felt like it needed to be on BW.

        This picture comes from NASA, and represents data from the Spitzer space telescope, showing spectra for organic molecules in extrasolar space.

        That’s right; complex carbon molecules, some of them possibly building blocks for life, floating around space.

        You may be wondering how this is happening.

        Well, there’s a team of researchers at the University of Hong Kong who asked just that, and came up with this answer:

        A new look at the interstellar dust permeating the universe has revealed hints of organic matter that could be created naturally by stars, scientists say.

        Researchers at the University of Hong Kong observed stars at different evolutionary phases and found that they are able to produce complex organic compounds and eject them into space, filling the regions between stars. The compounds are so complex that their chemical structures resemble the makeup of coal and petroleum, the study’s lead author Sun Kwok, of the University of Hong Kong, said.

        That’s right.  Stars may be producing and emitting all manner of organic compounds.  And if that’s the case, some things that we consider unique to Earth might be a lot more widespread.

          Humankind will slip next week into ecological debt, having gobbled up in less then nine months more natural resources than the planet can replenish in a year, researchers said Tuesday.

          […]

          Counting down from January 1, the date when human activity exceeds its budget — dubbed “Earth Overshoot Day” — had receded by about three days each year since 2001.

          The tipping point into non-sustainability happened sometime in the 1970s, said the Oakland, California-based Global Footprint Network, which issued the report.

          This year, researchers estimate that the equivalent of Earth’s resource quota will be depleted on September 27.
