8 Enter aspirin!
What causes pain and how do we stop it? This unit looks at how the human body responds to the release of certain chemicals and as a result feels pain. Pain can be reduced by inhibiting the formation of such chemicals and you will learn how the molecular structure of aspirin has been formulated to help in this process.

5 Conclusion The idea of the double whammy brings together the two driving forces behind changes in industrial structure, with which this unit opened and now closes. The use of a new technology causes a decline in the costs of production, which in turn encourages a rapid take-up by consumers of products embodying the new technology. This unit has explored the factors affecting consumer demand. While the price of the product was found to be of crucial importance, socio-economic influences such as culture a
4.3 Industrial dynamics: knowledge and network industries This final subsection introduces two more concepts that develop further our analysis of the dynamics of industrial structure, with particular reference to the ‘new economy’ industries. A dynamic approach to industrial change places considerable emphasis on innovation and learning, seeing firms as actively searching out innovative products and processes and learning how to produce and sell them. Some of the novelty of the new economy is reflected in the concepts used in trying to unde
4.1 Introduction This section will explore the interaction of technology and costs with market demand in shaping industrial structure throughout the industry life cycle. Many industries begin as a numerous and turbulent group of firms jostling for position, experimenting with new and idiosyncratic products, and turn into a much smaller, more stable number of firms, making standardised products by routine methods. In this section we add a rather different view of firms to that developed in Author(s):
Learning outcomes After you have completed this unit you should be able to: describe and give examples of how self-assembly enables construction ‘from the bottom up’ in natural materials; explain what is meant by primary and higher-order structure in proteins and give examples; give examples of the range of functions carried out by proteins within cells; describe how a combination of strong and weak bonding within biopolymers and lipids is use
Plate Tectonics: Lake Mead, Nevada
Contrary to what most geologists thought less than 100 years ago, we live on a dynamic planet. Earth's surface has changed in countless ways during the 4.6 billion years since it formed, and it continues to change today. This video segment adapted from Discovering Women looks at some of the geologic processes that have shaped the landscape near Lake Mead, Nevada, and suggests that these processes may be causing North America to slowly break apart. Closed captioning included. Run time 02:13.
Nucleic acids and chromatin
This unit helps you understand the properties of nucleotides and how they contribute to secondary and tertiary structures of nucleic acids at the molecular level. You will learn about the different composition and roles of nucleic acids in the cell, their interactions with each other and the use of ribozymes, aptamers, antisense and hybridization as tools in molecular research. The unit covers the function of DNA packaging within the cell, the interactions between the DNA double helix and the nu
Enhancing pupil learning on museum visits
Museums give children experiences above and beyond the everyday – experiences that enrich and build upon classroom teaching and learning. Taking pupils to a museum, or bringing museum artefacts into school, instantly changes the dynamics of the usual learning environment. It gives you as a teacher the opportunity to start afresh with each child, to reach and engage with pupils in new and different ways. This unit explores practical ways in which you can make the most of the UK's extraordinaril
