  • Some 90% of the island's plants and about 70% of its animals are endemic, meaning that they are found only in Madagascar. But what makes life on the island unique also makes it uniquely vulnerable. "If we lose these animals on Madagascar, they're gone forever," says Russell Mittermeier, president of the wildlife group Conservation International (CI).
  • Through our growing numbers, our thirst for natural resources and, most of all, climate change--which, by one reckoning, could help carry off 20% to 30% of all species before the end of the century--we're shaping an Earth that will be biologically impoverished. A 2008 assessment by the International Union for Conservation of Nature found that nearly 1 in 4 mammals worldwide was at risk for extinction, including endangered species like the famous Tasmanian devil. Overfishing and acidification of the oceans are threatening marine species as diverse as the bluefin tuna and reef-forming corals. "Just about everything is going down," says Simon Stuart, head of the IUCN's species-survival commission. "And when I think about the impact of climate change, it really scares me."

  • Usually, as a fluid is heated it will become less dense. A heated blob will feel
    a force pushing it upward, the blob will tend to rise, and cooler fluid will
    fall into its place. At the lowest heating rates, there is no motion. Then, as
    the heating rate is increased, one sees successively a steady motion, a periodic
    oscillation, and a chaotic domain.

    encouraged us to speak out and not worry about what anybody else thought, just
    be ourselves," Hillary remembers.

      • For decades, education has been an easy institution to define. It consisted
        of a set of accepted literacy skills, a definable body of knowledge, and the
        pedagogies for teaching those skills to willing students who were arranged in
        straight rows. Today, for the first time in decades (in generations of
        teachers)        , we are facing the challenge of changing our notions about
        teaching and learning to adapt to a rapidly changing world. We are struggling to
        rethink what it is to be educated, to reinvent the classroom, and redefine what
        it is to be a teacher and a student. There is much that has changed, and for
        much of it, we have responded to by attempting to ignore, filter, or to block it
        out.

The Future of RSS

  • RSS usage has since spread beyond simple news delivery. Companies like
    de.licio.us, Flickr and YouTube added another dimension to RSS - i.e. they made
    it an integral part of the Social Web (social networking, photos, video, etc).
