They developed human brain organoids, tiny clumps of brain tissue grown from stem cells, that unexpectedly grew rudimentary eyes. These eye-like structures, called optic cups, contained both a lens and a retina, just like real human eyes. Even more astonishing, the mini-brains’ “eyes” were light-sensitive and could send signals to nearby brain tissue, mimic

Medical on Instagram: "This video offers a captivating look at the major stages of human embryonic development—from fertilization to initial organ formation. It begins with a single-celled zygote and follows its journey through rapid cell divisions, implantation in the uterine wall, and the formation of the blastocyst. As development progresses, the animation highlights biological milestones such as gastrulation, germ layer formation, cell differentiation, and the emergence of primitive organs.
