EVOLVING MOLECULAR BOTS. "Nanotechnologists ... see the future of intelligent machines at the level of molecules: tiny robots that evolve and ... come together to form intelligent superorganisms. Perhaps the future of artificial intelligence will be both silicon- and carbon-based: digital brains directing complex molecular structures to copulate at the nanometre level and reproduce." Robotic swarming superorganisms. https://lnkd.in/dhAg_hD View in LinkedIn

FRAGMENT FROM NATURE this weekend is on bacteria without cell walls represent a peculiar class of organisms. They are called L-Form bacteria, and are a natural experiment for life without cells walls, as well as a model for an early primitive life form. These creatures turn out to be particularly interesting. This dovetails with the membrane adaptations of extremophile bacteria in previous Fragments. View in LinkedIn

CELL WALL DRIVERS. "The shapes of bacteria are determined by their cell walls, and with no cell wall, the L-forms have different shapes from their parent cells. For example, the L-forms of rod-shaped bacteria are typically spherical. L-forms also lack the internal cytoskeleton and cell organelles of their parent cells, creating novel morphological units including filaments, vesicles and granules." https://lnkd.in/dTCkxDw View in LinkedIn

"CELL WALL-DEFICIENT variants of bacteria that normally possess a wall have been described many times in the literature, since the original report of Klieneberger nearly 80 years ago ... the new L-form cells completely abandon the normally essential cell division machinery used by virtually all extant bacterial cells, and proliferate instead by a mechanism of membrane tubulation or blebbing." https://lnkd.in/dKmZZzy View in LinkedIn

MASSIVE HORIZONTAL GENE TRANSFER. "L-form-like growth and proliferation would have supported massive genetic flux or horizontal gene transfer. We have observed L-forms to undergo spontaneous fusion, potentially generating heterokaryons or chimaeric genomes, under certain conditions." https://lnkd.in/dKmZZzy View in LinkedIn
