Scientists have unveiled a groundbreaking preliminary atlas charting the intricate development of brain cells from early ...

German researchers have made a discovery that could change the ethical landscape for scientists working on embryonic stem cells. They found cells in mice testes that seem to have all the key ...

It’s challenging to sustain a pregnancy when food is short, or conditions are otherwise tough. That’s why many mammalian embryos can postpone their growth to get through periods of environmental ...

Scientists have created a 6-legged mouse embryo with an extra pair of hindlimbs at the expense of their external genitalia. But far from creating a monster, this rudimentary rodent provides important ...
