Baby pterodactyls could fly from birth

A breakthrough discovery reveals that pterodactyls, extinct flying reptiles, had a remarkable ability—they could fly from birth. The importance of this discovery is highlighted by the fact that no other living vertebrates ...

A first look at the earliest decisions that shape a human embryo

The factors that shape the destiny of a cell, like that of a fully formed person, remain something of a mystery. Why, for example, does one stem cell in a human embryo become a neuron rather than a muscle cell? And why does ...

Embryo

An embryo (irregularly from Greek: ἔμβρυον, plural ἔμβρυα, lit. "that which grows," from en- "in" + bryein "to swell, be full"; the proper Latinate form would be embryum) is a multicellular diploid eukaryote in its earliest stage of development, from the time of first cell division until birth, hatching, or germination. In humans, it is called an embryo until about eight weeks after fertilization (i.e. ten weeks LMP), and from then it is instead called a fetus.
