We think of ourselves as wholly distinct organisms – separate from the environment around us, and independent of other organisms. But zoom in closer, and you’ll see that the truth is far more complicated. All plants and animals maintain vital symbiotic relationships with an unfathomable quantity and diversity of microorganisms. And we are no exception. This encompasses the microbes on us, and within us. The best known example of this phenomenon is the gut microbiome , or the collection of bacteria and other microbes living inside the gastrointestinal tract. The number of microorganisms inhabiting the gut has been estimated to be as high as 10 14 – that equates to around 10 times more bacterial cells than human cells! On this basis, it has been argued that we collectively are, in fact, superorganisms . Given their staggering numerical superiority, it shouldn’t be surprising to learn that the amount and types of bugs you carry in your gut can make a big difference in how you

Graphic Work by M.C. Escher Maurits Cornelis Escher (1898 - 1972) was a Dutch graphic artist who made mathematically-inspired woodcuts, lithographs, and mezzotints. Despite the wide popular interest, Escher was for long somewhat neglected in the art world, even in his native Netherlands. He was 70 before a retrospective exhibition was held. In the twenty-first century, he became more widely appreciated, with exhibitions across the world. His work features mathematical objects and operations including impossible objects, explorations of infinity, reflection, symmetry, perspective, truncated and stellated polyhedra, hyperbolic geometry, and tessellations. Art not only for connoisseurs. Posted by Margaret from tu recepcja   via crss
