Cooperation, Norms and Conflict: Towards Simulating the Foundations of Society
In order to understand social systems, it is essential to identify the circumstances under which individuals spontaneously start cooperating or developing shared behaviors, norms, and culture. In this connection, it is important to study the role of social mechanisms such as repeated interactions, group selection, network formation, costly punishment and group pressure, and how they allow us to transform social dilemmas into interactive situations that promote the social system. Furthermore, it

Cell Fractionation in Tetrahymena
To illustrate cell fractionation, nuclei are isolated from the ciliated protozoan, Tetrahymena thermophila. A table top clinical centrifuge is used for the fractionation steps and the procedure is monitored microscopically using a differential stain. To determine the efficiency of the procedure, cell and nuclear counts are determined with a hemacytometer. To quantify DNA, the Diphenylamine Reaction is carried out and the amount of DNA per nucleus is calculated.

Benefits of Standardized Diabetes and Hypertension Screening Forms at Community Screening Events
The objectives of this project were to (a) assess hypertension and diabetes screening data collection practices and guidelines and (b) develop and test standardized screening forms for use at minority community- and faith-based screening events. Project Phase I involved resource assessment and the development of a set of screening forms and guidelines containing a core data set for both hypertension and diabetes. These were then tested during Phase II at predetermined communitybased screening ev

Class Discussion About Playing Ayiti: The Cost of Life
Ayiti: The Cost of Life is a role-playing video game in which the player assumes the roles of family members living in rural Haiti. At the start of the game, the player chooses a primary goal for his/her family: achieve education, make money, stay healthy, or maintain happiness. During the course of the game, the player encounters unexpected events and must make decisions that contribute to or detract from achieving the chosen goal. After students have played the game they will need to reflect u

Cyanobacteria Health Page
This Centers for Disease Control and Prevention (CDC) Health Studies page focuses on cyanobacteria, single-celled organisms thought to be the origin of plants. Cyanobacteria live in fresh, brackish, or marine water and are of concern to the CDC and Environmental Protection Agency (EPA) because some can form harmful blooms that deplete the oxygen and block sunlight that other organisms need to live. They can also produce powerful toxins that affect the brain and liver of animals and humans. This

Greenomes
The Greenomes site is part of a laboratory- and Internet-based curriculum to bring college students up to the minute with modern plant research. Plant molecular genetic and genomic research still lags behind medically-oriented research on microbes and higher animals. As a result, there are relatively few lab experiences that expose college-level students to the growing insights into plants offered by genomic biology.

Detection of Genetically Modified Foods
Genetically modified foods are often in the news and widely grown in the United States. Three US government agencies (USDA, FDA, and EPA) work to regulate the introduction and production of genetically modified foods. These crops can provide agricultural, ecological and nutritional benefits, but there are also potential risks to the environment and consumers. As consumers and public interest groups around the world have become aware of these risks, there has been a call for more explicit product

Bacterial Quorum Sensing and Bioluminescence
The bacterium Vibrio fischeri produces light when it is growing symbiotically in the light organ of certain fish and squid species. The bacteria sense they are in a light organ because they are present at a high bacterial cell density, which they detect through "quorum sensing." We use several bacterial strains, each of which carry only part of the genes responsible for the quorum sensing and bioluminescence process. We use chemical and genetic complementation to determine which genes are lackin

Vegetation Images Show Drought in Western US (WMS)
Satellite data can gauge the health of plants, which is a good indicator of drought. The Normalized Difference Vegetation Index (NDVI) measures how dense and green plant leaves are. NDVI images are useful as a measure of drought when compared to "normal" plant health. Scientists calculate average NDVI values for an area to find out what is normal at a particular time of year. This animation uses satellite imagery to show changes in vegetation between 1999 and 2003. In 2002, drought had settled a

3.1.1 Update: A move towards patient-centred care?
This unit considers the type of care offered in hospitals, using Leeds General Hospital as a case study. The unit looks at the people who have roles within the hospital, how they interact with each other and patients and what they consider to be 'care'. The different approaches and contributions to care by doctors and nurses are explored and patients give their perspective on the care they receive.

5 Distance and closeness
In this unit, we are going to look at a number of situations which put a strain on the idea that caring is just 'being ordinary', including times when people are giving intimate care. In these special circumstances, since the normal rules do not apply, we have to develop a set of special rules to guide practice.
