    marine worms follow fibonacci's lead
    wednesday, 18 june 2008 stephen pincock

    the complicated growth patterns of a group of common marine worms appear to be governed by simple mathematical rules built into their genes, a new report suggests.

    the report, which appears in the proceedings of the royal society b, suggests that the appendages that grow along the bodies of some species of polychaete worms follow a mathematical sequence known as the fibonacci string sequence.

    polychaetes, sometimes called bristle worms, have a segmented body, each with a pair of fleshy appendages covered in bristles.

    in one group, these appendages, known as dorsal cirri, grow in characteristic patterns of alternating short and long versions.

    one of the researchers, professor stephen glasby, a mathematician from central washington university, says each species exhibited different sequences.

    "different species by and large have different sequences of short and long appendages, and they can be quite complicated," says glasby.

    to better understand the numemic nature of the polychaetes, glasby worked alongside his brother dr chris glasby from the museum and art gallery of the northern territory and dr fredrik pleijel from gothenburg university in sweden.

    Default Neither fish nor fowl: Platypus genome decoded

    darwin takes another hit to the chin.

    paris (afp) — arguably the oddest beast in nature's menagerie, the platypus looks as it if were assembled from spare parts left over after the animal kingdom was otherwise complete.

    now scientists know why. according to a study released wednesday, the egg-laying critter is a genetic potpourri -- part bird, part reptile and part lactating mammal.

    the task of laying bare the platypus genome of 2.2 billion base pairs spread across 18,500 genes has taken several years, but will do far more than satisfy the curiosity of just biologists, say the researchers.

    "the platypus genome is extremely important, because it is the missing link in our understanding of how we and other mammals first evolved," explained oxford university's chris ponting, one of the study's architects.

    "this is our ticket back in time to when all mammals laid eggs while suckling their young on milk."

    i remember david touching on the concept of the platypus in either the science of peace or a subsequent audio blog. he suggested that perhaps some sort of geopathic energy, perhaps lightning, caused the same sort of dna conglomeration as was seen in the experiment with the chicken and the duck. that experiment being the one where microwaves where passed through one of the species onto the egg of the other. the result was the combo chicken duck.

    yeah they're an unusual animal.

    i've seen them swimming around in a river near where i live.

    Default Is this a new species?

    found this weird sponge at our lawn.
    it is transparent as a goblet.
    never haerd of a tranparent plant before, so wonder if it could be a new species.
    dont know if it is, but i would be gratefull for any comment that would highligt this issue.

    regards

    plants need the green substance to draw the energy from the sun.
    allthough its a bit different on sponge.
    this plant is tranparent, so how does it work on this plant?
    it has a purple glow on it. really weird plant.

    Default music from plants in tetrachords

    http://translate.google.it/translate...hl=it&ie=utf-8 "
    music secret plant the sap flows and produces notes
    ...
    i put the melody on the score of a tree a...nd tried to analyze it from a compositional point of view, structure - says silingardi - how much musical grammar i had to go back in time. technically, the green world produces notes through tetrachords. these melodies composed by the succession of four sounds, as happened in the music of ancient greece.

    Default Tomorrow's weather: Cloudy, with a chance of fractals

    tomorrow's weather: cloudy, with a chance of fractals
    04 november 2009 by robert matthews

    we've all watched those vast heaps of cotton wool float across the sky. lofted and shaped by updrafts of warm air, cumulus clouds mesmerise with their constantly changing shape. some grow ever taller, while others wither and die before our eyes. all bear witness to the ceaseless roiling of the ocean of air we call the atmosphere.

    about 80 years ago, the british mathematician lewis fry richardson was pondering the shapes of such clouds when a startling thought occurred to him: the laws that govern the atmosphere might actually be very simple.

    even at the time, with scientific meteorology still in its infancy, the idea seemed absurd: key equations governing the behaviour of the 5 million billion tonnes of air above us had already been identified - and they were anything but simple.

    no one was more aware of this than richardson, who is recognised as one of the founders of modern weather forecasting. even now, the world's most powerful computers are pushed to their limits extracting predictions of future weather and climate from the equations he wrestled with using pencil and paper.

    yet richardson suspected that behind the mathematical complexity of the atmosphere lay a far simpler reality - if only we looked at it the right way.

    now an international team of researchers analysing signals from satellites, aircraft and ground-based stations have found clear evidence that richardson's intuition was right and that the complexity of the atmosphere could really be an illusion.

    the results point to a new view of the atmosphere as a vast collection of cascade-like processes, with large structures the size of continents breaking down to feed ever-smaller ones, right down to zephyrs of air no bigger than a fly.

    the implications promise to transform the way we predict everything from tomorrow's local weather to the changing climate of the entire planet. "we may never be able to view the atmosphere and climate in the same way again," says team member shaun lovejoy of mcgill university in montreal, canada. "rather than seeing them as so complex that only equally complex numerical models can make sense of them, we're seeing a kind of scale-by-scale simplicity."

    Default Earth’s Most Stunning Natural Fractal Patterns

    earth’s most stunning natural fractal patterns
    by jess mcnally

    from sea shells and spiral galaxies to the structure of human lungs, the patterns of chaos are all around us.

    fractals are patterns formed from chaotic equations and contain self-similar patterns of complexity increasing with magnification. if you divide a fractal pattern into parts you get a nearly identical reduced-size copy of the whole.

    the mathematical beauty of fractals is that infinite complexity is formed with relatively simple equations. by iterating or repeating fractal-generating equations many times, random outputs create beautiful patterns that are unique, yet recognizable.

    we have pulled together some of the most stunning natural examples we could find of fractals on our planet.
