Biology is the science of life, from simple bacteria to complicated organisms. Biologists pursue a wide range of interests, among them researching diseases, exploring the evolution of organisms, modeling the complexity of ecosystems and examining the distribution of living organisms.
Students of biology develop an understanding of how living things work and affect each other. They work to answer new questions about the natural world, whether it is about environmental impact or human health and well-being. Will building a new dam destroy a rare flower or increase populations of parasites? Where did the latest Salmonella outbreak originate? Why are some cancers resistant to chemotherapy? How do we make a vaccine for AIDS? Biologists perform research to discover answers to these questions, apply their research, and teach the discoveries to a new generation.
