John Wilkinson, a frog ecologist at the Open University, said it appeared, from pictures taken before the escape, to be an extremely unusual find. "I have certainly never seen anything like it before.

That’s a frog embryo, leaving its egg to enter the world, and this embryo can hatch at will. The red-eyed tree frog lays its eggs on a branch or leaf above the water. Once they’re in the last ...

Using blobs of skin cells from frog embryos, scientists have grown creatures unlike anything else on Earth, a new study reports. These microscopic “living machines” can swim, sweep up debris ...

Stem cells from frog embryos have been transformed into self-healing robots, capable of having memories to recall events that will help researchers make further analyses.

Although the resulting embryos lived for just a few days, the groundbreaking research by an international team has brought the 'de-extinction' of creatures like woolly mammoths a step closer.
