Active Transport in Insect Malpighian Tubules
The Malpighian tubules of insects are an excellent model for examining the properties of secretion in a transporting epithelium. In this exercise students expose tubules from cockroaches or crickets to chlorophenol red and visually estimate the dye concentration in the lumen. By adding metabolic inhibitors and competitors or by substituting ion-free media they can demonstrate competition, specificity, and energy- or ion-dependence of active transport. Advanced students can design their own exper
What is Europe?
The European Union (EU), formed out of the ashes of the Second World War, continues to expand in the wake of the collapse of the Soviet Union. Despite the EU's growing size and significance the question 'What is Europe?' still resonates through the continent. This unit looks at a range of different views on the question, contrasting different conceptions of Europeanness and outlining competing visions for the future of the EU.

A Religious and Cultural Clash or a Tribal Showdown - Analysing the Danish Cartoons Crisis.
Length: 25 minutes
The publication of cartoons satirising the Prophet Muhammad in the Danish newspaper Jyllands-Posten has triggered violent protests across the world. The cartoons, which have been reprinted in a number of European papers, have angered Muslims and focussed attention on the fragile relationships between Islamic countries and the West.
Do the cartoons represent a fundamental difference in the religious and cultural values of the two communities or is the current crisis the lates
How terrorism has invaded German law - Professor Thomas Weigend
Professor Thomas Weigend (University of Cologne). The threat of terrorism hit Germany in two waves, the first in the 1970s and 1980s, the second in the general context of 11 Sept., 2001. Both waves have led to extensive legislation in substantive and procedural criminal law. The 1970s saw the introduction of the new criminal offence of being a member of a terrorist organisation as well as ad hoc legislation cutting back on the rights of the defence. More recently, the powers of the State to use

Ruth Rendell interviewed by David Grylls
Acclaimed crime writer Ruth Rendell discusses with David Grylls, Director of Studies, Literature and Creative Writing, the latest edition of the Penguin Complete Sherlock Holmes, for which she has supplied the introduction.
Symbols of Culture
PTPI's Global Youth Murals Project poses a wonderful introduction to the ways in which children around the world represent their cultures through visual art. Using this collection in the Global Gallery, learners can examine different depictions of culture as an entry point to studying cultures of countries around the world. This activity can be an introductory exercise to social studies or world geography research projects.
Setting Goals, Building Solutions
In this lesson, students consider the value of setting goals for themselves and for their community, thinking critically about the idea of defining community and shared interests and concerns. This is an introduction to the concepts that underlie the Millennium Development Goals.
Learning to Think Mathematically
Concerned that most students leave college thinking of mathematics as a fixed body of knowledge to be memorized, Cooperstein designed a new course to help students learn to think mathematically for themselves. This website serves as a course portfolio that documents the new class, Introduction to Mathematical Problem Solving. The principal activity in the class involved students working on and discussing novel problems which required them to formulate experiments, work out cases, look for patter
18.05 Introduction to Probability and Statistics (MIT)
This course provides an elementary introduction to probability and statistics with applications. Topics include: basic probability models; combinatorics; random variables; discrete and continuous probability distributions; statistical estimation and testing; confidence intervals; and an introduction to linear regression.
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
An Introduction to DNA: Spectrophotometry, Degradation, and the 'Frankengel' Experiment
In this laboratory students perform three exercises as an introduction to the basics of handling and analyzing DNA. In the first, they expose circular plasmid, linear phage, and high molecular weight genomic DNA samples to a variety of physical, thermal, chemical, and enzymatic conditions that might be expected to affect DNA integrity. The DNA's are analyzed by electrophoresis on a group agarose gel. In the second, they pour and reconstruct a "Frankengel" (a gel containing sections with three di
Europe's awakening
One of the most remarkable features of modern European history is the gradual emergence of that theoretical reasoning and experimental practice focused on the natural world that today we call science. In this unit we throw light on that eventual emergence of modern science in Europe by examining its beginnings in Greece and making comparisons with the early achievements of Chinese and Islamic science. You then return to medieval Europe in order to understand the intellectual and social origins o
Complex numbers
You may have met complex numbers before, but not had experience in manipulating them.
