With 4.5 billion humans infected with parasitic worms, its no surprise that half of all living creatures are parasites. While the mere mention of internal parasites may make some queasy, Dennis Minchella finds their unique lifestyles and cleverness fascinating. Minchella, a professor of biological sciences and associate dean of the College of Science, became interested in parasites while taking an invertebrate zoology course as an undergraduate student. He enjoyed learning about parasites mechanisms for survival and how they can transmit themselves to different hosts. Coevolution between hosts and parasites is one of the main areas Minchella studies. As hosts develop defense mechanisms against parasitic infection, the parasites find intelligent ways of adapting against the hosts defenses, entering what is known as a coevolutionary arms race. Within a coevolutionary arms race, hosts are coming up with ways to thwart their parasites and then their parasites are getting over those obstacles, said Alyssa Gleichsner, a Ph.D. candidate in biology and assistant in Minchellas lab. Minchella works mainly with schistosomes, parasites which penetrate humans skin after their larvae complete a stage of their life cycle in snails. Within his lab in Lilly Hall, Minchella replicates the schistosomes entire life cycle ... minus the … Continue reading →

So you're asking, what is BIOLOGY? Well... Here's our best definition. Biology is the study of LIFE and the changes that take place with and around all living things. And don't just think we mean Earth. The study of biology covers every planet and object in the Universe. In the same way everything on Earth is made up of atoms, everything that is alive on Earth is made up of cells. An entire living thing can be one cell or it can be billions. Most cells on Earth have similar pieces and parts. Let's get started and look inside cell structure. Go take a look! Now it's time for you to dive into our life science pages and start learning. Remember, the site offers an introduction to the science of biology. If you're not into graphics like home page image above, check out the site map where we list all of the pages of the site for you.

Biology is the study of life and living organisms, from the smallest bacteria to giant sequoias. Biologists use observation and experimentation to gain an understanding about the natural world. Branches of biology include anatomy, biotechnology, botany, cell biology, ecology, genetics, medicine, microbiology, molecular biology, and zoology. Many people entering the field of biology become specialized in a particular area. As a course, biology encompasses four main themes: 1. The process of evolution drives the diversity and unity of life 2. Biological systems utilize free energy to grow, reproduce, and maintain life functions 3. Living systems store and transmit information essential to life processes 4. Biological systems interact with each other, and those interactions possess complex properties. The Biology Corner is a resource site for biology and science teachers and students. It contains a variety of lessons, quizzes, labs, web quests, and information on science topics for all levels, including introductory life science and advanced placement biology. You can find lessons related to biology topics in the links listed under topics on the sidebar as well as specific curriculum for biology classes taught in high school.

en espaol Cell Membranes Learn that membranes are fluid, with components that move, change, and perform vital physiological roles as they allow cells to communicate with each other and their environment. Cell Signaling Learn that living organisms constantly receive and interpret signals from their environment. Cells of multi-cellular organisms also receive signals from other cells, including signals for cell division and differentiation. Studying Cells Introduce yourself to the cell as the fundamental unit of life and the scientific method. The Cell Cycle & Mitosis Understand the events that occur in the cell cycle and the process of mitosis that divides the duplicated genetic material creating two identical daughter cells. Meiosis Understand the events that occur in process of meiosis that takes place to produce our gametes. Prokaryotes, Eukaryotes, & Viruses Learn about the cells that make up all living systems, their organelles, and the differences between living cells and viruses. The Cytoskeleton Learn that the cytoskeleton acts both a muscle and a skeleton, and is responsible for cell movement, cytokinesis, and the organization of the organelles within the cell. CELLS Alive! is a highly visual site, where you will find movies and animated illustrations on cell processes, parasites, penicillin and … Continue reading →

Promoting research using a feminist lens to approach biology, University of Wisconsin will be home to the nations first post-doctorate program in feminist biology this fall after a donation. Approaching science with a feminist viewpoint is important because there are certain assumptions about men, women, objectivity and knowledge that influence how science is often done, associate professor at the Center of Womens Health and Womens Health Research, Judith Houck, said. Looking at science through a feminist lens allows old questions to be observed in new ways, she said. Feminist biology attempts to pinpoint and adjust gender bias in biology. UW was granted the opportunity by Gertraude Wittig, a German Ph.D. biologist in the 1950s,Janet Hyde, professor of psychology and director of the Campus Center for Research on Gender and Women, said. Wittig suffered through bias and sexism that many women faced during that time frame, she said. After working for the U.S. Department of Agriculture for several years, Wittig researched universities nationwide with strong gender and womens studies programs to find one she believed had a strong emphasis on the intersection of gender and science, Hyde said. She concluded that ours was the best one to give the money to … Continue reading →
