1.2.6 Summary of Section 1.2

  1. Many people wish to limit the number of their offspring, and so resort to contraceptive measures.

  2. Chemical contraceptives interrupt the production of gametes, or prevent implantation.

  3. Mechanical or barrier contraceptives prevent egg and sperm from meeting and, in the case of IUDs, prevent implantation.

  4. Surgical methods of contraception involve physical alteration of the reproductive tract so as to prevent eggs and

1 Natural groups

Darwin made extensive observations on a great many creatures, including mammals, and noticed that species fell into natural groups, e.g. lions, tigers and leopards have many similarities, and resemble cats. On the basis of his observations, he was able to place mammals in distinct groups.

His work has continued, and we now recognise that mammals have evolved from a common ancestor, and have branched into many different groups, or ‘Orders’. The animation below shows the different O

1 Why is information security important?

This course introduces you to information security and its management.

A succinct definition of information security might run as follows:

Information security is the collection of technologies, standards, policies and management practices that are applied to information to keep it secure.

But why is it important to secure information? And how should its security be managed? To

1 Physics and the physical world

Studying physics will change you as a person. At least it should. In studying physics you will encounter some of the deepest and most far-reaching concepts that have ever entered human consciousness. Knowledge gathered over many centuries, that has been subjected to continuous scientific scrutiny, will be presented, along with its applications. Fact will follow fact, useful theory will succeed useful theory. Amidst this rich mix of information, newcomers to physics might not always appreciate

Today We Drop Bombs, Tomorrow We Build Bridges: how foreign aid became a casualty of war [Audio]
Speaker(s): Peter Gill | In his latest book Peter Gill reveals how the ‘war on terror’ has ravaged the independence and neutrality of humanitarian aid, with serious consequences for relief operations. Focusing on Turkey, Afghanistan, Somalia and Pakistan he explains how western counter-terror laws are restricting humanitarian relief operations and costing lives. Peter Gill is a current affairs reporter working in Asia, the Middle East and Africa. Michiel Hofman is the Senior Humanitarian Spe

Alporas' closed cell aluminium foam
Additions are made to molten aluminium or aluminium alloy to modify the melt viscosity and make it suitable for foaming. 1 to 3 wt% titanium hydride is then added to the melt, and this foams the melt by releasing hydrogen. The foamed melt solidifies to yield a closed cellular structure with an average cell size of 4.5 mm

2.3 A closer look at ethical issues

Science can define what is practicable, what can be done, but it cannot determine which developments it is right to pursue; this is largely an ethical judgement. One sensible approach in making an ethical assessment is to try to weigh up the benefits of a technology against its potential to do harm. Deciding whether GM technology is acceptable, in ethical terms, then involves a judgement about the plausibility and moral weight of competing sets of claims. Individuals may make widely different

4.1 Scientific approaches

Even after many years of research, the phenomenon of hibernation continues to be a mystery to scientists. Despite coming nearer to an understanding of how and why it happens, some fundamental questions remain unanswered. Is there a genetic basis underlying the evolutionary predisposition of animals to hibernate, given its occurrence in many groups of vertebrates and invertebrates? Is the problem of metabolic adaptation in cells separate from thermal regulation which occurs throughout the orga
