    Yep, would take a massive hard-sale job, and the venting (according to the articles I've read) is dispersed over too great an area for economical harvesting anyway.

    It adds more weight to the notion that our planet & solar system are typical rather than outliers in the scheme of things.

    On the astronomy front... dark matter may be sterile neutrinos or then again maybe not.

    New dwarf planet discovered in orbit beyond Pluto.

    http://www.smh.com.au/technology/sci...327-zqneq.html

    Apparently the solar system is larger than previously thought, as this ostensibly confirms the presence of objects in solar orbits at distances which had been theorized but not actually found.


    Most sensationally, models to explain how the dwarf planet got there also supposedly indicate that it may imply the gravitational force of another, much larger object in a distant solar orbit as well. (Specifically something like a solid planet 10x the size of the Earth)

    I think I saw a Godzilla movie about this once--they've found the home planet of Monster Zero.

    Evolutionary surprise: Eight percent of human genetic material comes from a virus

    The research showed that the genomes of humans and other mammals contain DNA derived from the insertion of bornaviruses, RNA viruses whose replication and transcription takes place in the nucleus. Feschotte wrote on recent research led by Professor Keizo Tomonaga at Osaka University in Japan. Feschotte said this virally transmitted DNA may be a cause of mutation and psychiatric disorders such as schizophrenia and mood disorders.

    Tegmark takes as his starting point two requirements put forth by Tonini as a starting point and analyzes the implications in terms of quantum mechanics and math (I think) to see what the implications are.

    Guilono Tonini made this idea more specific and useful, making a compelling argument that for an information processing system to be conscious, it needs to have two separate traits:
    1. Information: It has to have a large repertoire of accessible states, i.e., the ability to store a large amount of information.
    2. Integration: This information must be integrated into a unified whole, i.e., it must be impossible to decompose the system into nearly independent parts.
    This isn't a discovery or reporting observations but a hypothesis and a very interesting one too.

    Another idea is the 'perceptronium', the most general substance that feels subjectively aware. I've sometimes wondered if a person could code cleverly or invent the right logic function would self-awareness pop out - is there a perceptronium in computer science (the holy grail)?

    Anyway, a bit from the summary

    We focused not on solving this problem, but rather exploring the implications of this viewpoint. Specifically, we have explored five basic principles that may distinguish conscious matter from other physical systems: the information, integration, independence, dynamics and utility principles.
