This course serves as an introduction to the fundamental principles of separation operations for the recovery of products from biological processes, membrane filtration, chromatography, centrifugation, cell disruption, extraction, and process design. This course was last taught during the regular school year in the Spring semester of 1999, but has been a part of the MIT Technology and Development Program (TDP) at the Malaysia University of Science and Technology (MUST), as well as at MIT's Professional Institute in more recent years.

Our bodies are finely-calibrated, organic machines that are capable of dealing with the fluctuations of our internal systems in response to stimuli. We are able to regulate these changes through feedback loops in order to maintain the self in a prime ‘operating condition’ known as homeostasis. While deviations from homeostasis may occur, the body has processes in place to eventually return to normal. Long term or highly disruptive deviation, to the point where the body’s natural feedback loops are insufficient at correcting the error, is an indicator of something abnormal at work—be it parasite, virus, or organ malfunction.
The Earth also displays similar mechanisms of homeostasis—complex feedback loops that allow it to regulate temperature, gas concentrations, and pH. Normally, small fluctuations are regulated within the system. Negative feedback loops maintain balance through chemical processes like the sink and release of carbon gases. However, as excessive fossil fuel combustion tips the scales, it is likely that we are moving further away from the point where these feedback loops are enough to return the carbon cycle to balance.
We can see symptoms of this deviation in alteration of the climate, increased warming, and the thawing of glaciers and permafrost. The study of these indicators allow us to monitor the disease and provide insight into the underlying cause. The feedback loops found in the carbon cycle are unable to rectify the anthropogenic carbon output post Industrial revolution, leading to some alarming trends. The greater the divergence from normal the greater the impact these indicators have on the system of the planet until, like the human body, there is irreparable harm to the system.
Is this warming a fever-- a planetary self-preservation system precipitated by the intemperate combustion of fossil fuels-- that aims to overcorrect the problem before returning to homeostasis in the geological timeline? How does a ‘sick’ planet impact our own health? This unit addresses the consequence of anthropogenic carbon sourced global warming on the planetary system and human physiology.

Snapshot Wisconsin is a partnership to monitor wildlife year-round, using a statewide network of trail cameras. Snapshot Wisconsin provides data needed for decision making at the Wisconsin Department of Natural Resources. It is also a unique opportunity for individuals, families, and students to get involved in monitoring the state’s valuable natural resources. This tool is designed to help visualize many aspects of Snapshot Wisconsin data.

Discusses social, ethical and clinical issues associated with the development of new biotechnologies and their integration into clinical practice. Basic scientists, clinicians, bioethicists, and social scientists present on four general topics: changing political economy of biotech research; problems associated with the adaption of new biotechnologies and findings from molecular biology for clinical settings; the ethical issues that emerge from clinical research and clinical use of new technologies; and the broader social ethics associated with investigations of population genetics and social problems. Use of cases and recent literature.

Over the course of three sessions, students act as agricultural engineers and learn about the sustainable pest control technique known as soil biosolarization in which organic waste is used to help eliminate pests during soil solarization instead of using toxic compounds like pesticides and fumigants. Student teams prepare seed starter pots using a source of microorganisms (soil or compost) and “organic waste” (such as oatmeal, a source of carbon for the microorganisms). They plant seeds (representing weed seeds) in the pots, add water and cover them with plastic wrap. At experiment end, students count the weed seedlings and assess the efficacy of the soil biosolarization technique in inactivating the weed seeds. An experiment-guiding handout and pre/post quizzes are provided.

This map shows 15 general soil regions of Wisconsin. On the landscape, many of these regions appear distinctly different from each other because differences in land form and use are often related to the characteristics of the soils. Map is available from ~ University of Wisconsin-Extension, GNHC, and Wisconsin Geological and Natural History Survey. F.w. Madison, Wisconsin Geological and Natural History Survey H.F. Gundlach, U.S. Department of Agriculture, Soil Conservation Service. 1993.

In this activity, students model how scientists work together to gather evidence. They are given pieces of a jigsaw puzzle and asked to make a claim about what the entire puzzle picture looks like. Each round they are given more pieces (more evidence). As the activity progress, they are also able to discuss the evidence with other students (scientists). This activity is used as an engaging activity for a unit on evolution and leads to a discussion and futher lessons on how a theory develops.

This resouce is a lesson plan that aims to inform about how animals use sound to avoid for competing for space. Also that there are ways to analyze the land management levels. This lesson plan includes essential questions, 3 part lesson, materials such as recordings and maps, and is connected to the Next Generation Science Standards.

Echolocation is the ability to orient by transmitting sound and receiving echoes from objects in the environment. As a result of a Marco-Polo type activity and subsequent lesson, students learn basic concepts of echolocation. They use these concepts to understand how dolphins use echolocation to locate prey, escape predators, navigate their environment, such as avoiding gillnets set by commercial fishing vessels. Students will also learn that dolphin sounds are vibrations created by vocal organs, and that sound is a type of wave or signal that carries energy and information especially in the dolphin's case. Students will learn that a dolphin's sense of hearing is highly enhanced and better than that of human hearing. Students will also be introduced to the concept of by-catch Students will learn what happens to animals caught through by-catch and why.
