Seals give birth only when conditions are right. After mating, a female seal can delay implantation of the embryo in the ...

Scientists study ancient unicellular organism C. perkinsii to understand transition from single-cell to multicellular life. Research suggests C. perkinsii demonstrates early forms of multicellular ...

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 ...

Images of the multicellular development of the ichthyosporean Chromosphaera perkinsii, a close cousin of animals. In red, the membranes and in blue the nuclei with their DNA. The image was obtained ...

Scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why ...

One of the biggest quests in biology is understanding how every cell in an animal's body carries an identical genome yet ...

In a bid to improve organ transplant options in the future, a team led by researchers at the Chinese Academy of Sciences has shown that it's possible to produce pig embryos containing "humanized" ...

Is there only one optimal configuration an organism can reach during evolution? Is there a single formula that describes the trajectory towards the optimum? And can we 'derive' it in a purely ...

LONDON (Reuters) - Scientists in Britain have applied for a license to create hybrid embryos using human cells and animal eggs for stem cell research to develop new treatments for diseases such as ...
