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

Baby snakes spiral as embryos. We didn’t know why, then scientists discovered a structure we had never seen in an animal before
What you'll discover in this article ・Snake embryos coil as they develop, allowing them to reach long body sizes while still ...
CT scans began to fill in the gaps, revealing a previously unidentified biological structure: an intestine located outside the embryo's body, but enveloped by blood vessels stretching from the yolk.

Comb jelly embryos reveal embryonic signaling center shared across early animal evolution
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 ...
An international team led by Canadian researchers has found evidence explaining why snake embryos form a curious spiral. This ability to coil as embryos enables snakes to hatch with the longest bodies ...
Research that mixes human cells into animal embryos could get US government funds for the first time under a new proposal that has stoked concerns about ethics and the limits of science. Some say the ...
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 ...
Think of a small fossil as the equivalent of a homemade video of prehistoric life. Fossils formed when sea organisms began their great proliferation more than half a billion years ago rarely contained ...
Discover how fossil embryos from the Cambrian period reveal insights into ancient life and the role of bacteria in preservation. Animal fossils are usually the remains of hard structures - bones and ...
