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...

What's in a Cell? *suitable for home teaching*

This Catalyst article explores the complex structure of cells, and numerous theories of how they were formed. It describes how the development of electron microscopes has allowed greater detail of cellular strutures and organelles to be understood. The article includes detailed electron micropgraphs, along with...

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...

The Chemistry of the Noble Gases *suitable for home teaching*

This Catalyst article looks at the noble gases (Group 0 or 8 in the periodic table) which are almost inert. This article shows how they were discovered through the use of fractional distillation and looks at their chemical and physical properties.

This article is from Catalyst: GCSE Science Review 2011,...

Models of the Atom *suitable for home teaching*

This article investigates the history of models of the atom and discovers how, a century ago, scientists were devising models of the atom in an attempt to explain the limited evidence they had about the fundamental structure of matter.

The article is from Catalyst: Secondary Science Review 2015, Volume 25,...
