Predators, Prey and Populations

A Catalyst article about predators. The article explores some general principles about predator–prey relationships and looks in some detail at the adaptations shown by a predatory insect being used in the control of an insect pest.

Printing in Three Dimensions

This Catalyst article looks at 3D printing, a new technology which is rapidly finding applications. Although probably too slow for mass production it is useful for producing prototypes and tailor-made items. In a 3D printer, layers of polymer beads are printed one on top of the other. Heat melts the polymer beads...

Probiotics, Prebiotics

A Catalyst article about the human gut and the many microbes it hosts, mainly bacteria. Probiotics are live bacterial ingredients or supplements designed to multiply in the colon and have an impact on health. A prebiotic is a carbohydrate that is not digestible by humans. The article examines the role they play,...

Process Chemistry

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...

Proxima b: our next homeworld?

This Catalyst article explores Proxima B, which is an exoplanet orbiting in one of the nearest star systems to the Solar System. It looks at how estimates of its temperature suggest it might be a suitable target for future human.

Pterosaurs - Flying Reptiles

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...

Publish or Perish: Getting into Print

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...

QTC - Making the Most of a Novel Material

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...

Quick Reactions *suitable for home teaching*

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...
