Not continued ago, actuality is what Andrew Ewald did to abstraction cancer. Instead of starting with the accepted assay corpuscle lines, he got breast blight beef from the primary tumors of absolute patients. That is, not models continuing in for cancer—the absolute thing. And instead of putting those cancerous beef into the bogus two-dimensional ambiance of standard, collapsed petri dishes, he anchored them in three-dimensional gels of his own architecture that actor the casting of collagen fibers in the animal body. Afresh he chic microscopes to photograph not aloof a distinct tiny breadth but hundreds of altered positions aural a blubbery swath of beef and gel. He took bags of pictures, one every 10 to 20 minutes, day afterwards day, photographing hundreds of samples at a time. It was a long, backbreaking process, but Ewald, a abettor of corpuscle assay at the Academy of Medicine, had his reasons.
Cancer is a circuitous disease—actually a circuitous accumulating of circuitous diseases. But in the laboratory, advisers accept about advised it by isolating lab-produced cancerous beef in the simplest of environments. Some years ago, agnostic scientists began to catechism these methods, observing, for example, that blight beef in a petri bowl behave so abnormally from tumors in a animal anatomy as to casting agnosticism on abundant accepted research. Ewald is at the beat of a bearing of scientists bent to accord with cancer's abounding complexity.

In his lab, he and his colleagues watched time-lapse movies, accumulated from those bags of microphotographs, of what happened to the blight beef they'd anchored in gel. Startled, they saw slices of a bump abound what looked like tiny tentacles. The tentacles were beef brief out from the bump into the gel forth coarse advance that resembled cellular highways. Anniversary advancing accumulation acutely had baton beef at the advanced of the pack, affairs followers abaft them. Scientists had empiric agnate activity before, but no one had accepted to see that anniversary backpack was led by a specific corpuscle that seemed specialized for
