3 Hot dry rock (HDR) fields
Energy from sources other than fossil and nuclear fuels is to a large extent free of the concerns about environmental effects and renewability that characterise those two sources. Each alternative source supplies energy continually, whether or not we use it. This unit considers one of these alternative sources, geothermal energy derived from the interior heat of the Earth, and the potential for this alternative to supplant fossil and nuclear fuel use to power social needs fast enough to avoid t

Ethics and Enlightened Leadership
His Holiness the Dalai Lama spoke at an inaugural event for a new institute in his name, the Dalai Lama Center for Ethics and Transformative Values.

1.5.3 Looking forward: implications and possible consequences

But what are the implications of these developments and trends? Clearly the emergence of a strong east-Asian bond market could threaten both the US dollar and the Euro markets, but this development is still in its infancy, and there are significant political and economic differences of interest amongst the possible east-Asian participants in such a market. So for the time being it will be the Euro and the US dollar that hold centre stage. But in as much as the Euro becomes a stronger currency

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;

Learning outcomes
In this unit, we study one aspect of the fluctuating nature of an organism's environment. We consider how organisms living in a temperate climate, such as that in Britain, are adapted to cope with winter. You will see that there is much diversity of adaptations among organisms, with different species coping with the demands of a fluctuating environment in quite different ways. As cyclic variations are a widespread feature of environments, the range of adaptations to them is an important source o

1.3. Moving forward

Language is constantly changing: words come and go and human history is caught like a fly in amber in words we use without thinking every day. By developing in our students the awareness of links, cognates, changes in meaning, oddities of spelling and sound, we enrich not just their mother tongue and foreign languages but their knowledge of global history of the last two thousand years.
