The UK takes the first steps towards legalising the creation of animal/human hybrids for use in stem cell research Don’t say hybrid: say cybrid. That’s the new name for an embryo created by combining ...

In order for vertebrate embryos to develop their body axes, they require what is known as an embryonic signaling center. This group of cells provides the instructions that determine where up and down, ...

According to Nature, a Japanese stem-cell scientist is set to be granted government backing to develop animal embryos that contain human cells. These embryos will then be transplanted into surrogate ...

A snake begins life coiled tightly inside its egg, its body folded into a spiral many times longer than the shell that ...

Snake embryos develop in remarkably consistent clockwise spirals, and their slower-growing gut may explain how the unusual ...

Snake embryos begin life curled into a distinctive right-handed spiral, and scientists may finally know why. Their bodies grow faster than their guts, creating a tether that forces the lengthening ...

The first few days of a human embryo’s development, known as pre-implantation, are important. It’s when the first cells are formed, and these decide if the embryo can survive, how it will implant in ...

Snake embryos develop in a tight spiral, and these early stage coils always form dextrally, or towards the right. But how ...

The next time you go wild swimming, whether in a lake, river or sea, you are probably sharing the water with one of your tiniest, yet closest relatives. Choanoflagellates, like most single celled ...

Destructive Human Embryonic Stem Cell Research—The term “destructive human embryonic stem cell research” means any research that involves the disaggregation of any human embryo for the purpose of ...
