3.1 Features of the diving response

All the aquatic mammals' adaptations to life in the water - breathing, moving, staying warm and making sense of the environment - come together in their diving behaviour, and the diving abilities of marine mammals are truly awe-inspiring. The elephant seal, for example [p. 192], makes repetitive, long-duration dives and some 80-95% of its time at sea is spent submerged. Its dives are of about 20 minutes duration on average, and the intervals at the surface are seldom more than about two minut

Introduction

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

10.9 The media and public understanding of cloning and genetic medical research

Hargreaves, I., Lewis, J. and Speers, T. ‘Towards a better map: Science, the public and the media’, Economic and Social Research Council.

The topic of cloning and genetic medical research has received a great deal of research in terms of the public understanding of science. The Wellcome Trust, in particular, (an independent research-funding charity that aims to improve human and animal health) has played a key role in researching public attitudes towards cloning.

Introduction

This course will give you an opportunity to think about some of the key concepts and methods of the discipline of religious studies. You will meet examples of different forms of religious practice and belief, mostly from Britain and India, and will compare the ways in which boundaries are drawn (or not drawn) between what is held to be ‘religious’ and ‘non-religious’ in two different societies.

The aim of this course is to explore three key questions:

22.611J Introduction to Plasma Physics I (MIT)
In this course, students will learn about plasmas, the fourth state of matter. The plasma state dominates the visible universe, and is of increasing economic importance. Plasmas behave in lots of interesting and sometimes unexpected ways. The course is intended only as a first plasma physics course, but includes critical concepts needed for a foundation for further study. A solid undergraduate background in classical physics, electromagnetic theory including Maxwell's equations, and mathema

Shedding new light on learning disorders

4.2 'Biological control'

We are also guilty of importing exotic species, some of which, like the rhododendron (imported from Asia to Europe), have run riot in the absence of natural predators or primary consumers, and so have tended to out-compete native plants. Sometimes introductions have been accidental; rats and many disease-causing organisms have spread around the world via relatively modern transportation such as sailing ships. However, deliberate introductions, such as the rhododendron, have been made with wor

5.1 Monogamy and polygamy

You've seen plenty of evidence that reproduction in rodents - more precisely what I've called their reproductive strategies - are versatile and varied. You'll appreciate that 'versatile and varied' describes the range of sexual habits seen in the rodents as a group, not the behaviour within a single species. As DA says, some are monogamous, which means that individuals mate exclusively with one partner, over at least a single breeding cycle or season. The marmots are an example of a group tha
