Chemistry in a Cage

This Catalyst article explains how zeolites, sponge-like materials developed from naturally occurring minerals, are used as chemical sieves and as catalysts. Zeolites have incredibly widespread applications. They are used in consumer products such as washing powder and cat litter while many of the petrochemicals...

Circadian Rhythms

This Catalyst article looks at how an internal biological clock within every cell of the human body helps to co-ordinate and organise human behaviour and metabolism into approximately 24-hour rhythms – allowing organisms to synchronise with, and anticipate, day and night. When the body clock is disrupted in humans...

Clam Shells, Climate Change and Ageing

This Catalyst article looks at the discovery of the Arctica Islandica, a mollusc which carries a record of past environments in the banding of its shell. In 2006, scientists collecting material from the seabed off the north coast of Iceland found some clam shells which remarkably were found to have come from...

Climate Modelling

A Catalyst article about the sudden onset of an ice age and whether it is a scientific likelihood. Looking at evaporation, greenhouse gases and thermohaline circulation in the world's ocean currents the article explores likely scenarios for a major drop in temperature.

Cloud Control

A Catalyst article about climate control, and specifically the process known as cloud seeding. Cloud seeding has met with initially encouraging results. The method entails adding silver iodide to the air in clouds to encourage ice crystals to form, so that they grow rapidly and produce more snow or rainfall than...

Coming to a Beach Near You!

A Catalyst article examining what causes breaking waves to leave foam on the beaches. The article explores the human impact on the environment and the changes in the growth of algae in the seas.

Conker Tree Science

This article discusses how simple observations of pests on horse chestnut trees can contribute to a 'citizen science' project. The article is from Catalyst: Secondary Science Review 2015, Volume 25, Issue 4.

Catalyst is a science magazine for...

Conservation Biologist

In this Catalyst article, David Edwards studies ways of reducing the impact of human activities in tropical regions. The article is from Catalyst: Secondary Science Review 2014, Volume 25, Issue 3.

Cook Electric

A Catalyst article looking at the use of gas and electric for cooking. The article focuses on the latest hobs which use radiant, halogen or induction electric heating, to see if they can compete with gas.

Cool Chemistry

A Catalyst article about the work of a scientist from the British Antarctic Survey, gathering data about climate change by studying ice cores from Antarctica. One of the areas of research was to find out whether it is possible to learn how much sea ice there was around Antarctica in the past by measuring how much...
