Catalyst Volume 18 Issue 2

This issue of Catalyst contains articles on:

Would You Be a CLEVER Driver?

The CLEVER car has been designed to be a compact, energy-efficient car. Many of its design features are likely to appear in more conventional cars in the near future.

Studying Lung Surfactant

The inner surface of human lungs is coated with surfactant, allowing oxygen to enter the bloodstream. Some babies suffer breathing problems because they lack this vital substance.

Radioactive Waste Decisions

How are decisions taken about controversial issues such as the sitting of a radioactive waste store?

A Close Look at Pollen Grains

The scanning electron microscope shows up the structures of pollen grains and can help research into why some people suffer from hay fever.

Arctic Coral Reefs

The Arctic Ocean expeditions have revealed previously-unknown deep-sea coral reefs. How do these havens of biodiversity survive, and how are human activities damaging them?

Year of the Sun

The article describes the International Heliophysical Year (2007-08) - a year of scientific collaboration, studying the Sun and the impact of its radiation on the Earth.

Energy-efficient Lighting

This article assesses whether energy-efficient lighting is good for the environment.

Measuring Surface Tension

This article shows how to conduct a home experiment on surface tension.

Studying Lung Surfactant

A Catalyst article about the inner surface of lungs, which is coated with surfactant, allowing oxygen to enter the bloodstream. When babies are born very prematurely they can lack this surfactant, and this can make it very difficult for them to breathe. This is called Respiratory Distress Syndrome (RDS). This...

Radioactive Waste Decisions

A Catalyst article about how decisions taken about controversial issues such as the sitting of a radioactive waste store. How does a government decide where to put such a dump? And how can citizens affect the decision making process? The article examines how governments try to involve their citizens in decision-...

A Close Look at Pollen Grains

A Catalyst article about how the scanning by an electron microscope of pollen grains shows up their structure, and can help scientists understand why some people suffer from an allergic reaction - hay fever. The article describes how the images were made and how they are used in scientific research.

Arctic Coral Reefs

A Catalyst article about recent expeditions to the Arctic Ocean which have revealed previously-unknown deep-sea coral reefs. The article explains how these havens of biodiversity survive, and how human activities are damaging them.
