Thinking

Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine. The human brain may be the most complex structure in the universe.

The brain is so powerful that it is attempting to understand itself, through research. New techniques have opened up ways of exploring the brain....

Nanoscience

From the Wellcome Trust, the 'Big Picture' looks at issues in science.

Dealing with things smaller than 100 nanometres (for comparison, a human hair is 80,000 nm wide), nanotechnologies are fast becoming the 'next big thing'. Yet while nano-enthusiasts say they are the future, nano-sceptics are concerned...

Little book of fast facts

Each issue of the Big Picture is on a different topic in biology and comes with its own sprinkling of ‘fast facts’, fascinating snippets of information on the topic. This booklet brings together the best of the fast facts from the last fourteen issues, sorted into eight themes, for use in project work, as part of...

Influenza

Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine. Written at the time of the H1N1 swine flu outbreak, it looks at the nature of influenza, drugs and vaccines that can fight it.

Looking at the H1N1 influenza pandemic, the resource explores how it compares to...

Health and climate change

Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine. The Earth's climate is changing ever faster, and human activities play a role in speeding up this change.

The Earth’s climate is changing. In fact, it has always been changing. What is different now is the speed...

Drugs *suitable for home teaching*

Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine.

While providing immense benefits, drugs are not the perfect solution. They only work on a proportion of patients, sometimes they harm us, and we're not very good at taking them as we should. For some diseases,...

Proteins *suitable for home teaching*

These resources explore proteins by their different function, with examples of how they give structure to living things, carry messages and molecules around our bodies, support the immune system, catalyse chemical reactions, and their use in industry and medicine:

Structure and movement How...

Make Your Own Indicator

This Catalyst article describes how an indicator changes colour when in solutions of different pH. Most indicators simply turn one colour in acid and another in alkali, although they are often an in-between colour when neutral. A universal indicator only turns as many colours as it does because it is a mixture of...

Investigating RTAs *suitable for home teaching*

A Catalyst article about road traffic accidents (RTAs). After the accident police and other investigators try to establish what went wrong. This may be with a view to prosecuting a motorist, or simply in an effort to improve road safety. An understanding of the physics of motion plays a large part in such...

Evolution *suitable for home teaching*

Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine. Why does Darwinian evolution raise controversy when, say, quantum mechanics scarcely registers on the public consciousness?

This issue of 'Big Picture' looks at the theory of evolution, the evidence that supports...
