Is there only one optimal configuration an organism can reach during evolution? Is there a single formula that describes the trajectory towards the optimum? And can we 'derive' it in a purely ...

Chimpanzee naive pluripotent stem cells (PSCs) can now be grown in cellular cultures, reveals a recent study. They successfully created chimpanzee early embryo models, called 'blastoids,' and found ...

Like all complex organisms, every human originates from a single cell that multiplies through countless cell divisions. Thousands of cells coordinate, move and exert mechanical forces on each other as ...

The Gazette offers audio versions of articles using Instaread. Some words may be mispronounced. Every time I see a letter denouncing evolution, I think back to my sixth-grade science class where the ...

With embryolike constructs built entirely from stem cells, researchers can revolutionize our understanding of development. But how close to an embryo is too close? In April, researchers in China ...
