A Catalyst article about physicists working at Europe’s Large Hadron Collider who hope to have received the first results from what is probably the biggest, most expensive and most ambitious scientific experiment ever carried out. Later, they hope to solve the mystery of the fundamental forces of nature.

A Catalyst article about modern car engines and how they can run smoothly and propel drivers for thousands of miles without needing much attention, apart from refuelling with diesel or petrol. The engine also needs oil. The article describes engine oil, its composition and ingredients, how it works and how to...

A Catalyst article about homeostasis describing how the process enables birds and mammals to be active on cold days when other species are not.

A Catalyst article discussing how the human body has to handle all sorts of variations, balancing its inputs and outputs, if it is to work efficiently. The article concentrates on one organ, the kidney, and the way it helps to keep things on an even keel through the functions of homeostasis and excretion. What...

This Catalyst article looks at kidneys and how they are vital organs so it is important to understand how genetic disorders may affect kidneys and develop treatments to overcome them.

A Catalyst article about light emitting diodes and how they are more energy efficient than existing light bulbs which waste most of the energy they receive. The article explains how LEDs work and how they can be applied in traffic lights. Creating white light from LEDs is difficult and the article looks at possible...

A Catalyst article about devising better, more energy-efficient lighting. In particular the article focuses on LEDs. Like food, water, clothing and shelter, light is essential to daily life and is needed by most people for most of their waking hours. The article explains how LEDs work and how they are made.

This Catalyst article looks at scuba diving, and how having a knowledge of physics is vital in helping divers to get out of dangerous situations. Divers must be trained to control their buoyancy, and to ascend and descend at a safe pace to avoid injury. Other factors explored in the article are the effects of...

A Catalyst article investigating if there is life elsewhere in the universe. Scientists have found many different ways of looking for life. This article looks at the exploration so far.
