Science as Investigation: A First Majors Course Teaching the Process
The first laboratory course biology majors take should challenge their expectation that biology is the mere memorization of knowledge. Rather, it should introduce them through experience to the scope and limitations of scientific investigation. Following a brief introduction to epistemology and the nature and goals of science, this course provides students with a developing understanding of scientific thinking, methodology, and experimental design. During the final unit of the course students de

Spot-Overlay Ames Test of Potential Mutagens
This protocol represents a cost-effective modification of the Ames Test that allows students to investigate the mutagenic potential of various common substances. Potential mutagens are tested using well-characterized auxotrophic strains of Salmonella typhimurium. By analyzing the results, students determine if any of their compounds may be mutagenic. Follow-up experiments are designed to determine the dose response of these potential mutagens. Using this protocol, we have achieved reproducible r

The Use of Fossils in Interpreting Past Environments
The earth's environment has changed dramatically over the past 4.5 billion years. A comparison of the remains of fossilized and recent organisms, associated with an understanding of geological processes (both past and present), allows scientists to interpret what ancient environments were like. This exercise was developed to help students understand (1) how past environments are determined and (2) how paleontological specimens illustrate such concepts as evolution, extinction, adaptation, paleob

At the community school in Neve Shalom-Wahat al-Salam - named in both Hebrew and Arabic - children learn both languages at a very young age, thus cultivating a spirit of communication and mutual understanding. The village is a true rarity, as Jews and Palestinian Arabs live together in cooperation and respect.

Medicine transformed: On access to health care
Access to healthcare is important to all of us. Did the arrival of state medicine in the twentieth century mean that everyone had access to good medical services? If you fell sick in 1930 where could you get treatment – from a GP, a hospital, a nurse? This unit shows that in the early twentieth century, access to care was unequally divided. The rich could afford care; working men, women and children were helped by the state; others had to rely on their own resources.

Uniform convergence and pointwise convergence
The aim of this material is to introduce the student to two notions of convergence for sequences of real-valued functions. The notion of pointwise convergence is relatively straightforward, but the notion of uniform convergence is more subtle. Uniform convergence is explained in terms of closed function balls and the new notion of sets absorbing sequences. The differences between the two types of convergence are illustrated with several examples. Some standard facts are also discussed: a unifo

Democracy and Prosperity: reinventing capitalism through a turbulent century [Audio]
Speaker(s): Professor Sara Hobolt, Professor Torben Iversen, Professor David Soskice | It is a widespread view that democracy and the advanced nation-state are in crisis, weakened by globalisation and undermined by global capitalism, in turn explaining rising inequality and mounting populism. At this event Torben Iversen and David Soskice will discuss their new book, Democracy and Prosperity: The Reinvention of Capitalism in a Turbulent Century, which argues this view is wrong: advanced democrac
