Cell biologists investigate the amazing world of organisms too small to be seen with the naked eye. Although they're known by many different titlesincluding molecular biologists, biochemists, and microbiologistsall cell biologists are scientists who study living organisms and infectious agents, many of which can only be seen with a microscope. They also study the interaction of these tiny organisms with people, how they exist and affect our lives. Cell biologists work with many other scientists and have a vast range of opportunities. Many industries employ these specialists, making this a viable career goal for today's students.

In the modern world, genetics has brought about more dramatic breakthroughs than any other field of biological study. These breakthroughs have a wide impact, from curing diseases to growing better vegetables to catching criminals. The field of genetics is in the midst of a revolution, and at the center of it is genetic engineering:the alteration of genetic material by direct intervention in genetic processes. Some of the biggest strides in genetic engineering and related fields are taking place in the realm of medicine. Genetic engineering in the area of health aims at understanding the causes of disease and developing treatments for them. Gene therapy is another outgrowth of these studies.
