A new deep learning model performs a task that biologists have struggled with for centuries -- how to measure the incredibly complex process of embryonic development. Scientists have shown that the AI ...

A gene that turns on very early in embryonic development could be key to the formation of the placenta, which provides the ...

With a shiny snout and pink, veiny face, an image shared on X on Oct. 15, 2023, claimed to show a dog embryo after seven days of gestation. At the time of this publication, the post had received more ...

Researchers have gained new insights into the mechanism behind the spatial organization of DNA within the cells of early embryos. When an embryo is first formed after fertilization, each cell has the ...

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 ...

Every face is unique. Genetics helps to determine our features, but sometimes genes have errors which, in early fetal ...

As the debate over the ethics of human embryonic stem cell research has caught fire over the last year, there's been enormous discussion about whether scientists should be allowed to destroy human ...

A fossilized dinosaur embryo discovered inside a fossilized egg in southern China is reshaping scientific understanding of avian evolution. Preserved for more than 70 million years and left unexamined ...
