Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

The little clump of cells looked almost like a human embryo. Created from stem cells, without eggs, sperm, or a womb, the embryo model had a yolk sac and a proto-placenta, resembling a state that real ...

For decades, animal models have been the gold standard for preclinical testing of potential drugs. Yet, even the best animal models are not perfect. For example, small rodent species with engrafted ...

Artificial intelligence has traditionally advanced through automatic accuracy tests in tasks meant to approximate human knowledge. Carefully crafted benchmark tests such as The General Language ...

Transplanted human stem cells successfully repaired macular holes in monkey models of the disorder. This is according to a new study from researchers at the Center for Biosystems Dynamics Research at ...

The original version of this story appeared in Quanta Magazine. Among the myriad abilities that humans possess, which ones are uniquely human? Language has been a top candidate at least since ...
