A Catalyst article looking at how gel electrophoresis is used in DNA fingerprinting. Gel electrophoresis is used to separate big molecules, in particular nucleic acids and proteins. To learn more about the structure and function of large molecules such as DNA and proteins, they can be broken up into smaller...

A Catalyst article about the life and work of Gertrude B. Elion a pioneer in anti-viral drugs. The ground breaking research methodology she used and her work in creating and investigating purine compounds lead to the development of drugs which are used in the treatment of leukaemia.

Scientists say that the average global temperature has increased by around 0.5^oC over the last century. Is this evidence of global warming, initiated by the excessive production of greenhouse gases? Students will look at real monthly maximum and minimum temperature and rainfall data taken in Southampton...

This Catalyst article looks at how humans are exposed to radiation from many different sources, including food. The article describes the doses of radiation from sources such as:

• building materials and rocks
• bananas
• bone scans
• cosmic rays
• radon gas
