(Phys.org) —Last month, researchers reported the creation of the first primitive brain-like structures made from human stem cells. To create the complex morphology of these cerebral organoids, cells within a proliferating ...
(Phys.org) —It's a parent's nightmare: opening a Lego set and being faced with 500 pieces, but no instructions on how to assemble them into the majestic castle shown on the box. Thanks to a new approach by scientists at ...
