2.4 Variable fecundity

The food supply for most polar species depends on several unpredictable factors so successful breeding is far from certain, even if births are tightly synchronized with the seasons. Maintaining pregnancy and feeding the offspring after birth (or hatching in birds) are energetically expensive. The death of the offspring before its maturity represents an irredeemable loss of ‘reproductive investment’ for the parents, particularly the mother, although the earlier in parental nurturing that t

Introduction

This course looks at three different uses of genetic testing: pre-natal diagnosis, childhood testing and adult testing. Such tests provide genetic information in the form of a predictive diagnosis, and as such are described as predictive tests. Pre-natal diagnosis uses techniques such as amniocentesis to test fetuses in the womb. For example, it is commonly offered to women over 35 to test for Down's syndrome. Childhood testing involves testing children for genetic diseases that may no

6.1 The intricacies of neuron growth

Particular nerves, such as those sensory nerves that arise from the nasal retina (the side of the retina adjacent to the nose), cross the midline; other sensory nerves, such as those that arise from the temporal retina do not. This pattern is consistent between individuals, to such an extent that a map of the nervous system is good enough to be used to locate a particular nerve pathway in most people.

2.4 Fuel requirements for nuclear reactors

The fission energy of uranium-235 is 8.2 × 1013 J kg−1. Setting this figure in the context of fuelling a reactor depends on:

  1. The thermal efficiency of the reactor — For modern burner reactors, this is similar to that of modern fossil fuel power stations, about 35% (i.e. 65% of the available energy is lost within the reactor-coolant-turbine system).

  2. The power output — A typical value for a bur

Powering the Planet: The Challenge for Science in the 21st Century
The supply of secure, clean, sustainable energy is arguably the most important scientific and technical challenge facing humanity in the 21st century. Rising living standards of a growing world population will cause global energy consumption to increase dramatically over the next half century. Within our lifetimes, energy consumption will increase at least two-fold. This additional energy needed is not attainable from long discussed sources, the global appetite for energy is simply too much. Pet

4.3 Cellular changes

Hibernation can result in the deposition of fat in adipose tissue. In tissues of finite size which are important sources of energy and sites for fuel metabolism, changes in cell structure (redistribution of organelles involved in energy metabolism and protein synthesis) are the most likely adaptation to a state of torpor. Liver hepatocytes of the hibernating dormouse (Muscardinus avellanarius), are visibly different from those of arousing and euthermic dormice when viewed in thin secti
