A Catalyst article describing how process chemists work in the pharmaceutical industry, devising methods of making new drugs. Process chemists are a link in the chain from an initial idea to a new drug making it to the market. It generally takes at least 10 years from an idea by a medicinal chemist to a new...

This book describes young people’s attitudes, beliefs, motivations and behaviours that affect their decisions on subject choice and career paths to add depth to the current understanding of how young people perceive STEM careers.

Four phases of research activity with young people; qualitative, social...

This Catalyst article looks at the pterosaurs, which were flying reptiles, and which died out along with the dinosaurs. Analysis of the fossil record has increased scientists' knowledge of these creatures and how they lived. Bird watching during the Mesozoic Era, the expanse of time stretching between 245 and 65...

A Catalyst article explaining what happens when a scientist makes an exciting and new discovery. How do scientists manage to tell as many people as possible, and how can they be sure that someone else has not beaten them to it? Writing and publishing research in scientific journals is a long standing and popular...

A Catalyst article about Quantum Tunnelling Composite, a material discovered in 1997 and whose resistance decreases dramatically under pressure. How does it work and what uses will it have? The material has been carefully characterised (to understand its composition and how it works), and its first applications...

A Catalyst article which explores how the nervous system works. Sensitivity, the ability to respond to stimulation, is a product of nervous system activity. How nerve impulses pass around the body, and why these responses are so fast are investigated in the article. Neurones, reflexes, synapses and receptors are...

A Catalyst article explaining how weather forecasts can help keep the public safe in extreme situations by providing advance warnings: for example, airline pilots rely on accurate information about the development of thunderstorms to help them decide which routes might be at risk from lightning or violent...

A Catalyst article about the safe use of radiation. Radioactive materials are hazardous because they give out ionising radiation. Like many scientific discoveries, radioactivity provokes a mixed reaction. Some seek to commercialise it whilst films and comic books emphasise its harmful effects. The article takes the...

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 Catalyst article about radioactivity that was being spread among wildlife species in the Arctic in ways that no one had detected before. The source of this radioactive contamination and how radioactivity is detected are investigated.

This article is from Catalyst: GCSE Science Review 2004, Volume 15, Issue...

A Catalyst article about radiation and the many uses it has in medicine, both in finding out what is wrong with a patient (diagnosis) and in the treatment of cancer (therapy). The radiation used in medicine can come from electromagnetic radiation or from radioactive materials such as isotopes; the scanners using...

A Catalyst article about careers using radiography in medical procedures. The article looks at a typical working day for a radiographer, the types of radiography used, how to become a radiographer and the qualifications available.

This article is from GCSE Science Review 2006, Volume 16, Issue 3.

A Catalyst article comparing mobile phones and UV sunbeds. Mobile phones emit radiofrequency (RF) radiation. Tanning beds emit ultraviolet (UV) radiation. These are both types of non-ionising radiation. In recent years both have received considerable media coverage and they are emotive topics for the general public...

A Catalyst article about the life and work of the physicist Robert Hooke. Hooke was a man of many interests. He invented many mechanical devices, including the universal joint used in all cars and designed a balance wheel for a watch. As part of his wide ranging observations, using a microscope, he first coined the...

A Catalyst article about practical chemistry experiments and the risks involved. The article helps in identifying, assessing and controlling the risks involved, it also includes a guide to the warning signs, labels and symbols used in laboratories.

This article is from Catalyst: GCSE Science Review 2004,...
