What Causes the Aurora? *suitable for home teaching*

This article from Catalyst looks at aurora borealis caused by the interaction of the solar wind with the Earth's magnetic field. It also explains how satellites are testing thoeires of how this happens. Auroral light emission occurs at roughly 100 km altitude. Energetic electrons in the solar wind cause the...

The Other Genome Project *suitable for home teaching*

This Catalyst article details how the genome of a plant called Arabidopsis has been unravelled so that this species can act as a model in genetic studies. Arabidopsis thaliana is a model species like the fruit fly Drosophila, yeast, and the bacterium Escherichia coli.  Scientists...

Seeing Inside Cells *suitable for home teaching*

Each individual blade of grass consists of various tissues, each made of cells in their thousands. In these cells an as yet unknown number of reactions and interactions are constantly taking place. The cells contain different parts known as organelles, which can be thought of as the cellular equivalent of the...

Molecules From the Past *suitable for home teaching*

A Catalyst article looking at how modern archaeology uses analytical chemical techniques to answer questions about ancient civilisations and animals. Scientists working at the University of Bristol match compounds present in archaeological materials to those in modern plants and animals which were likely to have...

What Are Stem Cells? *suitable for home teaching*

This Catalyst article explains the use of stem cells to treat medical problems, and outlines new possibilities for the use of adult stem cells in treatment.

Currently, stem cells used for treatment are embryonic stem cells, since they have the ability to form any cell type in the body. The example of the use...

The Systems Physiology of Exercise *suitable for home teaching*

This Catalyst article looks at the effect exercise has on the body. Poor fitness contributes to poor life expectancy, and inability to exercise reduces quality of life in the ill or aged. Scientists hope to understand the mechanisms which limit 'exercise tolerance' which would contribute to enhanced performance for...

Fighting Fit *suitable for home teaching*

This Catalyst article looks at how exercise affects our immunity and susceptibility to infection. Recent research indicates that a person's level of physical activity affects their immune function, influencing their risk of respiratory tract infections such as a cold. Whereas moderate levels of regular exercise...
