The identification of disease before the birth of a fetus. It often implies genetic diagnosis, but identification of anatomical defects as well as assessment of fetal functions and maturity are also considered. Some of the relatively common diseases that can be diagnosed prenatally are Tay-Sachs disease, cystic fibrosis, Duchenne's muscular dystrophy, hemophilia A, congenital adrenal hyperplasia, thalassemia, and sickle cell anemia.

The common name for chymosin, a proteolytic enzyme that is used to coagulate milk in cheesemaking. Rennin participates in the cheese-ripening process through its proteolytic activity.
Industry:Science
Substances formed by the addition of one or more elements, usually metals, to lead. Lead alloys may exhibit greatly improved mechanical or chemical properties as compared to pure lead. The major alloying additions to lead are antimony and tin. The solubilities of most other elements in lead are small, but even fractional weight percent additions of some of these elements, notably copper and arsenic, can alter properties appreciably.
Industry:Science
The general term applied to the description of a disturbance which propagates from one point in a medium to other points without giving the medium as a whole any permanent displacement.

The ITER project is a major step toward realizing the potential of fusion as an essentially limitless, environmentally responsible source of power. ITER is being built in the south of France by a partnership of the European Union, Japan, China, India, Russia, South Korea, and the United States. These partners represent over half the world's population, so ITER is a global response to the global challenge of meeting future energy needs.
Industry:Science
The growth of crystals, of which all crystalline solids are composed. This article discusses the processes by which crystal growth occurs, and methods of artificially growing crystals.
Industry:Science
The ability to cool and trap atoms has led to a renaissance in atomic physics. Workers in the field of chemical physics are looking for ways to apply atom-cooling techniques to molecules. Molecular cooling will make it possible to study molecular collisions in a regime where the wave properties of the molecules are dominant as described by quantum chemistry. Molecular cooling may also allow the testing of fundamental theories of physics.

The genetic mechanisms by which sex is determined in all living organisms. The nature of the genetic basis of sex determination varies a great deal, however, among the various forms of life.
Industry:Science
The determination of the quantity of a fluid, either a liquid, vapor, or gas, that passes through a pipe, duct, or open channel. Flow may be expressed as a rate of volumetric flow (such as liters per second, gallons per minute, cubic meters per second, cubic feet per minute), mass rate of flow (such as kilograms per second, pounds per hour), or in terms of a total volume or mass flow (integrated rate of flow for a given period of time).
