Where Do Our Limbs Come From? AURORA, Colo. (May 24, 2023) – An international collaboration that includes scientists from the University of Colorado School of Medicine has uncovered new clues about ...

Pancrustaceans in general display a wide variety of developmental strategies and are morphologically diverse. The evolution of many compelling pancrustacean features, such as limbs and diverse nervous ...

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

Embryos in pregnancies that end in miscarriage take longer to develop in the womb than those in pregnancies that result in live births, according to new research published today (Monday) in Human ...
