A naturally occurring gene called Cyclin A2 (CCNA2), which turns off after birth in humans, can actually make new, functioning heart cells and help the heart repair itself from injury, including a ...

What if you could precisely change the genome of a pre-implantation human embryo and then safely use that embryo to try to generate a healthier person? It’s a wild idea, but one that technology over ...

Human gene maps contain major blind spots because they were built largely from the DNA sequences of people with European ancestry, according to a study published in Nature Communications. Researchers ...
