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...

A Catalyst article explaining how scientists have found that the overturning circulation in the Atlantic Ocean, which maintains Europe’s moderate climate, was weaker in 2004 by 30% relative to earlier estimates. What does this mean and what impact could it have on our climate? Scientists' research and their climate...

This Catalyst article looks at how scientists can use material recovered from archaeological sites to see how crops have been introduced to different countries over the history of farming. Three processes by which some plant material can be preserved are explained. The ratio of carbon isotopes from the collagen in...

This Catalyst article looks at how tomato plants have been genetically modified so that they produce high levels of substances thought to reduce the risk of diseases including cancer and heart disease.

This document looks at a variety of lessons devised by teachers in fourteen Leicester city schools, who took part in a project developing creative and cross-curricular links to practical science.

Supported by European Commission funding, the project supported European schools to raise standards in...

This Catalyst article looks at salt, in particular the process of extracting salt from the sea in the salt factories of Trapani in Sicily. Located on the west coast of the island, the saline (salt ponds) were probably started by the Phoenicians around 3000 years ago. The article also looks at the structure of salt...

This Catalyst article looks at NASA's Mars Curiosity rover, the automated chemistry lab which landed safely on Mars in August 2012. Capable of analysing samples from the planet's surface and atmosphere, the rover will undertake two years of experiments in the hope of discovering even more about our neighbouring...

A Catalyst article about Dolly the sheep which was born in 1996. The scientists who created her claimed she was a ‘clone’ from a female adult sheep. To prove this claim, genetic profiling or fingerprinting was done by another, independent group of scientists. The article explores how this was done and what other...

A Catalyst article about the work of Damian Murphy a music technologist. Acoustics and sound are examined in addition to the physical modelling and acoustics of buildings and environments, both real and virtual.

This Catalyst article is about using computer models which use natural selection to evolve new products. Computers can be used to simulate evolution showing how some species die out and how others evolve and thrive. Products used by humans in everyday activities also evolve and this article describes how their...
