Catalyst Volume 18 Issue 4
This issue of Catalyst contains articles on:
Body Sensors Networks
This article describes body sensor networks which are tiny electronic sensors used to monitor the movement of patients, athletes and game players.
This article draws on the work of a scientist from the British Antarctic Survey, gathering data about climate change.
To Sleep...Perchance to Dream
It is known that it is possible to study the electrical activity of the brain during sleep. But why do people sleep? Nobody really knows!
Ancient Air in an Antarctic Ice Core
Ice cores from Antarctica contain air bubbles which record the changing atmosphere. This evidence is vital in understanding how our climate is changing.
Careers in Ecology
Scientists with qualifications in ecology and environmental science play an increasingly important role in assessing the human impact on the Earth.
Earth's Early Atmosphere
By studying ancient rocks and sediments, scientists can deduce how the Earth's atmosphere has changed over billions of years. There used to be much less oxygen than today.
The human gut hosts many microbes, mainly bacteria. What role do they play, and can people change their diet to encourage 'good bacteria'?
Is Mars Dead?
This article draws on the new data suggesting that it is very unlikely that life ever existed on Mars.

HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
