Preamble
The genetic manipulation of plants and animals and their use in agriculture is one of the most controversial scientific developments of recent times. This unt takes a look at the 'science behind the headlines' and the complex interactions between scientific and social factors. By the end of the unit it's hoped that you will have a clearer idea of both what is GM makes possible as well as what may be thought desirable.

3 Chromosome structure and DNA replication
Genomes are composed of DNA, and a knowledge of the structure of DNA is essential to understand how it can function as hereditary material. DNA is remarkable, breathtakingly simple in its structure yet capable of directing all the living processes in a cell, the production of new cells and the development of a fertilized egg to an individual adult. DNA has three key properties: it is relatively stable; its structure suggests an obvious way in which the molecule can be duplicated, or replicated;

In this unit you will learn how advances in genetics could change the way in which diseases are diagnosed and managed. The advent of predictive medicine, based on more detailed DNA profiling of individual genotypes using technologies like gene chips, rather than screening for one gene at a time, may shift the relationship between doctor and patient. People will be seeking advice on how to manage their susceptibilities or genetic risks, rather than looking for treatment for an already existing di

Health and environment
To be able to understand the importance of the environment for our health, we need to know a little about the interdependence between environment and humankind. This unit will look at interactions between plants, animals and the physical and chemical environment, as well as considering ways in which humans have altered, and are altering this environment. These changes have health implications that are not always immediately obvious. Frequently, we initiate changes that are going to have their ef

Last Stand of the Great Bear
This hour long video tells the story of a 250-mile adventure through unspoiled territory along the coast of British Columbia called the Great Bear Rain Forest. It is here that bear-hunting wolves take to the sea, grizzlies clash in titanic battles and wild salmon are the pulsing lifeblood of an entire ecosystem. As this precious habitat faces an uncertain future, threatened by chainsaws and fish farms, a team of dedicated scientists is racing to prove that it must be protected. Forming a wildern

5.8 Conclusion
Life is full of risk. In this unit ‘risk’ describes the probability and consequences of harm or, at worst, disaster. Risk management involves many stakeholders and integrated management systems help to ensure that safety, quality, environmental and business risks are all managed correctly. This unit also looks at emergency preparedness, that is, the management of emergencies and disasters.

Predicting the Behaviour of Techno-Social Systems: How Informatics and Computing Help to Fight Off G
We live in an increasingly interconnected world of 'techno-social' systems, where infrastructures composed of different technological layers are interoperating within the social component that drives their use and development. The multi-scale nature and complexity of these networks are crucial features in understanding and managing them. In the last decade advances in performance in computer technology, data acquisition and complex networks theory allow the generation of sophisticated simulation
