Growing, aging, digesting—all of these are examples of chemical processes performed by living organisms. Biochemists study how these types of chemical actions happen in cells and tissues, and monitor what effects new substances, like food additives and medicines, have on living organisms.

Soybeans, corn, grass, algae, vegetable oil: What do these things have in common? The answer is that they can be used to create biofuels, which are derived from plants or plant material. These sources are called biomass. The procedure for converting plants or vegetable oil into a biofuel is a chemical reaction that has many steps. The biofuel or biodiesel technology and product development manager is a professional who develops ways to convert the raw material into fuel and improve the types,…

The human body can be viewed as a machine made up of complex processes. Scientists are working on figuring out how these processes work and on sequencing and correlating the sections of the genome that correspond to the individual processes. (The genome is an organism's complete set of genetic material.) In the course of doing so, they generate large amounts of data. So large, in fact, that to make sense of it, the data must be organized into databases and labeled. This is where bioinformatics…

What do the sequencing of the human genome, the annual production of millions of units of life-saving vaccines, and the creation of new drought-tolerant rice varieties have in common? They were all accomplished through the hard work of biological technicians. Scientists may come up with the overarching plans, but the day-to-day labor behind biotechnology advances is often the work of skilled biological technicians.

Life is all around you in beauty, abundance, and complexity. Biologists are the scientists who study life in all its forms and try to understand fundamental life processes, and how life relates to its environment. They answer basic questions, like how do fireflies create light? Why do grunion fish lay their eggs based on the moon and tides? What genes control deafness? Why don't cancer cells die? How do plants respond to ultraviolet light? Beyond basic research, biologists might also apply…

Life is all around us, in beauty and abundance, and the people who introduce students to how life forms live and interact are biology teachers. Their work helps develop the next generation of doctors, nurses, life scientists, and engineers. Their enthusiasm and appreciation for all life helps students understand their own bodies, and how life forms are all connected to each other and to their environments.

Shakespeare described humans as a "piece of work," and others have called the body "the most beautiful machine," but like any machine, sometimes body parts need repairs or servicing when the body cannot take care of the problems itself. That's where biomedical engineers come in. They use engineering to solve problems in medicine, such as creating replacement body parts, drug-delivery systems, medical instruments, and test equipment. Their work helps restore health and function, and improves the…

CAD (computer-aided design) technicians combine art and engineering to prepare the technical drawings and plans from which everything in the world is made—from toys to toasters, houses to hoses, satellites to sewer systems. CAD technicians are essential to the design and construction of everything you see around you.

The first leading cause of death in the United States is heart disease, and the third leading cause is stroke. Cardiovascular technologists or technicians are key members of the healthcare teams that are on the front lines of treating heart and blood vessel diseases and conditions. They set up monitors and tests to help physicians diagnose heart or blood vessel problems. Then they work with physicians to treat an identified problem. For example, they might help break up a blockage in an artery…

Maps can give us much more information than ways to get from A to B. Maps can give us topographic, climate, and even political information. Cartographers and photogrammetrists collect a vast amount of data, such as aerial data and survey data to produce accurate maps and models. For example, by collecting rainfall data, a cartographer can make an accurate model of how rainfall can affect an area's watershed. The maps and models can then be used by policy makers to make informed decisions.
