    We have anthropologist and author Jeremy Narby with us today from Switzerland who back in 1999 released the book "The Cosmic Serpent: DNA and the Origins of Knowledge", in 2006 "Intelligence in Nature" was released and he talks with us about his research and anthropological work in the Peruvian Amazon, living next to the Quirishari and studying the source of their knowledge about plants.

    We talk about DNA, the roots of knowledge, intelligence in nature, communication with the entities beyond this world from deep within, experiences on Ayahuascha, difference in cultures and more. Topics Discussed: Ayaschanica People, Ayahuasca, Quirishari, Carlos Perez Shuman, Visionary Journeys, Anthopology, Visions, Art of Scientific Investigation, Computer, Origins of Knowledge, Francis Crick, LSD, Double Helix Structure, The Realm of Visions, Molecular intelligence, Serpent Symbolism, Coding System of Genes, Biospheric DNA Television, Ayahuasca DMT, di methyl-tryptamine, Datura, Dreamworld, Modification of Consciousness, Studying the Cosmos, Avatar, Shamanism.

    "Native Americans, Aboriginal Australians, Taoists, Zen Buddhists, Tantric
    meditators, and mystics everywhere do not think of the Dreaming world
    as an 'un'-conscious. For these peoples, the sentient Dreaming world is
    the basic reality. Though marginalized and invisible to mainstream cultures
    today, Dreamtime has been the essential reality for people from the
    beginning of time."

    The Robotic Musicianship Group at Georgia Tech Center for Music Technology just blew our minds with some videos depicting robots playing music with real people. Great, you say. Some fake robot machine can, like, bang around on a drum or something. Not so fast, doubters.

    These robots, developed with funding from the National Science Foundation, listen to humans creating music in real time and play along with them. One might say they improvise.

    They can't pass the actual Turing test, in which a robot must fool a human into thinking it is also a human during a conversation.

    But musical improvisation is another kind of a conversation and I, a human, would believe that the impromptu, non-predetermined parts these robots play were played by other humans. By that standard, the Georgia Tech team's robots have already passed the musical Turing test (assuming that I'd feel the same way if I were playing along instead of watching the robots in a video, and I'm fairly certain I would).

    We asked professor Gil Weinberg, head of the program, how these robots manage to parse what humans are playing, and how they manage to play along. How do they figure out which parts to play? As it turns out, the process is somewhat analogous to the way Deep Blue plays chess: by carefully examining its options and then evolving them like biological species to see which one best fits a changing musical environment.

    "The processing allows [the robots] to analyze and improvise," said Weinberg via telephone. "In one of the applications, we use a genetic algorithm... You have a population of something, and then you do mutations to all of these little things — in my case it's musical motifs — mutations and cross-breeding between the musical genes, in our case, and then you have a new population that better fits to the environment.

    He continued, "Very fast, it runs [about] 50 generations of mutations that are cross-bred between the genes and tests whether this is similar to a motif that the saxophone player played, for example. And it plays something back that is a combination of musical genes of what the saxophone player played, what the piano player played — something that is unique that only can be the product of genetic algorithm."

    The results are fairly astounding. Haile, the drumming robot has been around for a couple of years, but Shimon, the marimba playing robot unveiled in early November, handles melody in addition to rhythm. One of the next steps, says Weinberg, is to give the robots to look at whichever human collaborator is playing the most interesting part.

    Bioplastics are becoming a burgeoning industry as the cost of oil climbs and the disastrous nature of petroleum-based plastics is revealed in full effect. This past Monday Metabolix announced an incredible development: they have found a way to generate “significant amounts” of ecologically-sound bioplastic by growing it directly in switchgrass. The fast-growing perennial plant is paving the way for a sustainable source of Mirel, the company’s biodegradable brand of bioplastic.

    Mirel will also biodegrade in a wide range of environments including soil, home compost, industrial compost, and both fresh and salt water. Mirel’s biodegradability may, in fact, help to reduce the persistent plastic waste that litters our landscape and threatens marine environments.
