Then researchers placed blastoids and embryos donated after infertility treatments inside the little device and watched it ...

Scientists have grown a scalable new embryo-like model that unshrouds some mysteries of early human development, including blood cell formation, or hematopoiesis—a first for the field. In an article ...

Scientists have developed an experimental way to study how human embryos implant in a uterus, which may provide new insights into why miscarriages occur and how they can be prevented.

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

Humans are the only primates that walk on two legs. Scientists believe that their uniquely shaped pelvis, the bones that connect the spine to the legs, makes this possible. However, researchers didn’t ...
