Researchers have developed a method to extract living cells from feces that they say could help conservationists better understand the genetic diversity of wildlife — and in the long run, could be ...

A Russian scientist who works at Harvard University’s Medical School has spent the last six weeks in immigration detention and is facing possible deportation after undeclared frog embryo samples ...

Not only that, they’re dire wolves—which means they have cause to be lonely. The dire wolf once roamed an American range that ...

The company that claims to have "resurrected" the dire wolf has its sights set on the woolly mammoth, dodo bird and Tasmanian ...

Scientists have made a leap in genetic engineering by pushing elephant cells into an embryonic-like state. This marks a major ...

For fertility patients who never dreamed they’d have extra embryos, decisions about what to do with the surplus are personal — and increasingly political Susie Sheehan sat alone on her couch ...

Another arm of research focuses on the artificial reproductive techniques necessary to implant a genetically modified elephant embryo into a living elephant and then bring that animal to term.

Using these stem cells, researchers have already managed to create structures that mimic the first developmental stages of real human embryos. At the same time, new research has opened up the ...

Elephants may be the champion mothers of the land-walking mammals. Elephant embryos gestate for 22 months, time enough to help them grow into young giants — elephants weigh around 240 pounds at birth.

I look at her and I think six years of trying, six years of IVF, multiple rounds of everything, surgeries, and you are the one embryo that survives." "If that isn't meant to be, I don't know what ...

Notice that following uncaging the embryos are maintained in a CYC-free E3 medium. Our hypothesis is further strengthened by the observation that the variation in cancer risk among tissues can be ...

Scientists have found a way to study early embryonic development without real embryos. Using CRISPR, they programmed stem cells to self-organize into structures mimicking early embryos. The cells show ...
