The early beginnings of an embryo as it transforms from a clump of cells to a tiny human is a bit of a mystery — scientifically speaking. We know many of the broad strokes, but there are a lot of ...

Dalhousie University provides funding as a member of The Conversation CA-FR. In January 2017, I met Jiankui He, the now-infamous Chinese scientist who would go on to create the world’s first ...

Scientists set a new record for growing primate embryos outside the womb, as reported in the May issue of the journal Cell. For the first time, monkey embryos were cultivated in a lab for 25 days post ...

A team of scientists has created synthetic human embryos from stem cells, without the need for either an egg or sperm — a remarkable breakthrough that raises plenty of thorny ethical questions. While ...

The early days of how an embryo develops are shrouded in mystery, because it pulls a kind of vanishing act. Once a sperm finds an egg, it begins a roughly weeklong journey to the uterus, becoming a ...

The images are unsettling, to put it mildly: a baby monkey whose skin grows eerily green, with glowing fingertips reminiscent of E.T. This is “#10,” the world’s first live-born monkey that’s largely ...

A team of American researchers has created cloned monkey embryos using a variation of the technique used to clone Dolly the sheep, and extracted stem cells from the early-stage embryos. The work ...

NEW YORK (AP) — Scientists have finally recovered stem cells from cloned human embryos, a longstanding goal that could lead to new treatments for such illnesses as Parkinson’s disease and diabetes. A ...

Scientists have cultivated monkey embryos in the laboratory long enough to watch the beginning of organ formation and the development of the nervous system — milestones that are difficult to observe ...

Two research groups have independently produced human embryonic stem-cell lines from embryos cloned from adult cells. Their success could reinvigorate efforts to use such cells to make ...
