Biology News, Articles And Features

Our mission is to instill an understanding and appreciation of the common thread that connects modern biological study at all levels, from molecules to ecosystems. All of these tools for state-of-the-art molecular and integrative biology research — as well as opportunities to do field research on our University farm and in the lush environment around campus — will be available to you as an undergraduate student. Biologists study the structure, function, growth, origin, evolution and distribution of living organisms. As a biology major, you might accompany your professors on a field expedition to study seabirds in Alaska, wild eggplants in Australia, giant salamanders in Japan, or bats, bees, and lightning bugs here in Pennsylvania.

In your first year, you’ll be in timetabled teaching activities such as lectures, seminars, practical classes and workshops, guided independent study sessions and fieldwork for about 14 hours a week. Kevin Dunbar and his students spent many hours meticulously interviewing real biologists from top laboratories, recording their lab meetings, and reading grant applications and manuscripts of research papers. On this module you’ll attend lectures, practical classes and workshops, and supervised time in a studio or workshops and you’ll take part in fieldwork study and guided independent study.

Biology examines the structure, function, growth, origin, evolution, and distribution of living things. The biological and social sciences frequently aim to provide rational explanations for the phenomena they study. In your lab experience, you’ll develop knowledge of the nutrition and growth of bacteria, fungi and viruses that can be used to culture and control microorganisms. On this module you’ll attend lectures and seminars, and take part in fieldwork study and guided independent study.

Taking the SAT Subject Test in either Biology Ecological or Biology Molecular can help you indicate to colleges that you are interested in focusing on science. Some universities will offer more specialised degrees within the biological sciences such as zoology or ecology. The 20th and 21st centuries may be known to future generations as the beginning of the « Biological Revolution. » Beginning with Watson and Crick explaining the structure and function of DNA in 1953, all fields of biology have expanded exponentially and touch every aspect of our lives.

Ecological systems are studied at several different levels, from the scale of the ecology of individual organisms, to those of populations , to the ecosystems and finally the biosphere The term population biology is often used interchangeably with population ecology , although population biology is more frequently used in the case of diseases , viruses , and microbes , while the term population ecology is more commonly applied to the study of plants and animals.

Cell theory states that the cell is the fundamental unit of life , that all living things are composed of one or more cells, and that all cells arise from pre-existing cells through cell division In multicellular organisms , every cell in the organism’s body derives ultimately from a single cell in a fertilized egg The cell is also considered to be the basic unit in many pathological processes.
