Two to three weeks after conception, an embryo faces a critical point in its development. In the stage known as gastrulation, the transformation of embryonic cells into specialized cells begins. This ...

The sculpting of the face during embryonic development - the physical molding that determines what we will look like - may remain open to change much longer than had been thought, according to ...

Roe deer are among the few mammals whose embryos go into a particularly long period of dormancy. Using modern molecular methods, researchers have shown for the first time what exactly happens in the ...

Week 3 of pregnancy is a critical stage when the embryo begins to grow rapidly. During this week, cells divide at an astonishing rate, laying the foundation for all future tissues and organs. This ...

Embryonic development is a critical process for all organisms including humans. Many different diseases can arise when there are problems during development, but it can be extremely challenging to ...

Why do pregnancies last longer in some species than others? Researchers have found the clock that sets the speed of embryonic development and discovered the mechanism is based on how proteins are made ...

Thermal manipulation during incubation represents an innovative approach to enhancing the physiological robustness of avian species in the face of escalating environmental temperatures. By ...

Reviewed by Michael Greenwood, M.Sc. Fertilization is defined as a process where gametes (an egg and sperm) join together to form a full zygote. Both the sperm and egg contain a single set of 23 ...
