Humans do not have tails, but do we have “what it takes” for a tail? Hens don’t have teeth, but they have the genes for it. With atavism, it is as if our genomes serve as archives of our evolutionary ...

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

Researchers have developed a method for culturing fertilized chick eggs without their shells. The eggs were placed in an artificial culture vessel made of transparent film, allowing for real-time ...

Scientists can now create realistic human embryo models in the lab, leading some to suggest that we rethink how we legally define an embryo. When you purchase through links on our site, we may earn an ...

Researchers have discovered that the earliest days of embryo development have a measurable impact on a person's future health and aging. Researchers from the University of Adelaide have discovered ...

Magdalena (Magda) Zernicka-Goetz, today a developmental and stem cell biologist at the University of Cambridge and California Institute of Technology, recalled being an artistic child who enjoyed ...

"Understanding embryo implantation and embryo development just after implantation has significant clinical relevance as these stages are particularly prone to failure," said Dr. Peter Rugg-Gunn, ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...
