Orchid allows parents to screen their embryos' odds for breast cancer, irritable bowel syndrome, and obesity. How dystopian.

Frozen embryos are filling storage banks around the world. It's a struggle to know what to do with them.

When Kristia Rumbley, a mother of four living in the Birmingham area, first heard about the Alabama Supreme Court’s controversial ruling on frozen embryos, her first thought was of her own.

Furthermore, comparison of embryos of hemichordates (a basal deuterostome), amphioxus (a basal chordate), and vertebrates revealed that the somites likely arose from the "endomesoderm" tissue of ...

In a massive breakthrough, microgravity was no match for mouse embryos aboard the ISS.

Recent breakthroughs in making stem-cell based human embryo models are raising urgent questions about to what extent they should be treated like natural embryos and whether they are open to misuse.

Interest in the ecology, biology and evolution of amphioxus is growing, and the availability of several species is helping to improve our understanding of chordate evolution.

Scientists achieved a significant breakthrough by successfully developing the first-ever synthetic human embryos.

In April, scientists implanted synthetic monkey embryos in female monkeys. While none of them developed into fetuses, this is a new development that raises important ethical questions.

Embryos made from stem cells—instead of a sperm and egg—have been created from monkey cells for the first time. When researchers put these “synthetic embryos” into the uteruses of adult ...

Analyzing 90 genetic elements from Ciona embryos, the experiments produced some of the first-known evidence that enhancer grammar and logic rules are conserved across the spectrum of chordate species, ...

New insights into chordate body plan development answer long-standing questions on evolution Examination of development-relevant gene expression patterns in starfish embryos reveals how echinoderm ...
