This Catalyst article explains how chemists build molecular 'traps' to mimic the surface of a cell. To scientists, sugar is much more than a food; sugar molecules can also form polymers which act as ‘molecular bar codes’ to help cells recognise each other. The article describes how chemists made a synthetic...

A Catalyst article about fainting and how it can be the result of a sudden drop in blood pressure, which is often part of a shock reaction. Maintaining blood pressure is an important part of keeping the human body in balance. This article examines hypertension, living with high blood pressure, and the relationship...

A Catalyst article about the use of tiny electronic sensors to monitor the movement of people. As electronic devices get smaller and more powerful, they are finding new uses in monitoring human activity. This article describes a project to develop sensors with uses in medicine, sport and electronic gaming.

Brighton Energy Co-op recently installed Brighton’s second-largest solar system on the roof of Shed 3a at Shoreham Port. Since May 2013, 800 panels have covered the two sides of this 3000 m2 roof: half face east, the other half west.

The article is from Catalyst: Secondary Science Review 2014, Volume 25,...

A Catalyst article about a temple singer who was preserved as a mummy over 2000 years ago in Egypt. She now lies inside a coffin in a museum in Manchester. Thanks to developments in medical science, researchers are revealing the secrets of her life and piecing together the diseases she suffered from by using X-rays...

This articles article looks at the work of astrobiologists, and how the study of extremophiles on Earth can help us to understand how we might colonise another planet in space exploration. ...

A Catalyst article about buckytubes, a type of carbon nanoparticle.The allotropes of carbon —diamond, graphite and buckminsterfullerene (bucky balls) — are well known. Now scientists are working on buckytubes. These are based on elongated tubes formed from sheets of hexagonally-linked carbon atoms, capped at both...

The BrickPi is an interface between the Raspberry Pi and LEGO Mindstorms or EV3 sensors and motors, a portable power source for the Raspberry Pi, and a case that allows you to attach LEGO motors, beams, sensors, and other parts.

This resource includes guidance on setting up and programming the Raspberry Pi...

This Catalyst article explores the processes undertaken during the construction of a white water canoe course for the Olympic Games which requires a huge range of practical skills, but also great science skills too. The scientist must calculate how much noise from both the course's construction and its use during...

A Catalyst article about a visit to CERN, the particle physics lab and what the centre has to offer a science student by way of a case study.

This article is from Catalyst: GCSE Science Review 2007, Volume 17, Issue 4.
