The practice of editing the genes of embryos remains highly controversial and risky, but Origin Genomics founder Cathy Tie argues its a “moral imperative” to address hereditary diseases. When the ...

The disposition of embryos created through assisted reproductive technology sits at a complex intersection of reproductive medicine, contract law, property rights, family law, and ethics. As fertility ...

A study by researchers at Columbia University Vagelos College of Physicians and Surgeons has found that new cutting-edge techniques can accurately edit genes in human embryos—giving scientists ...

Snake embryos begin life curled into a distinctive right-handed spiral, and scientists may finally know why. Their bodies grow faster than their guts, creating a tether that forces the lengthening ...

About 100,000 babies were born through in vitro fertilization in 2024, according to the most recent U.S. data. But IVF commonly involves trying to create multiple embryos, because success is never ...

Modern IVF treatment can now achieve substantially higher success rates than historical approaches while dramatically reducing twin and triplet pregnancies, according to new research presented at the ...

An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic models based on stem cells in the field of reproductive biology. The document, ...

A DNA-editing feat involving editing the genes of early stage embryos—a far cry from designer babies, but nevertheless a step in that direction—was announced this week. Dieter Egli, an associate ...

Researchers relied on a newer gene-editing technique that may make it possible to engineer embryos, a prospect that has long alarmed bioethicists. By Carl Zimmer Scientists at Columbia University have ...
