This Catalyst article looks at 'Restored Hearing', a business which grew out of a school science project. It provides therapy for sufferers of temporary tinnitus, a debilitating hearing condition caused by exposure to loud noises. The article looks at how hearing loss can occur and how also explains how the...

A Catalyst article about how engineers use their understanding of sound waves to develop highly realistic sound systems for films, music systems and computer games. The same ideas can help people with eyesight and hearing problems. Sound waves are affected by their surroundings and the article examines this along...

This Catalyst article looks at herbarium houses that contain plant specimens collected from around the world. Studying these specimens allows botanists to study how plants work and how we are impacting on the environment.

This Catalyst article looks at the Higgs boson, a fundamental particle discovered by scientists at the Large Hadron Collider (LHC) at CERN, Geneva, on July 4th 2012, after it was first predicted almost 50 years earlier. The Higgs boson is predicted by the ‘Standard Model’, which makes up the set of fundamental...

This Catalyst article looks at the work of Robert Hooke, an employee of the Royal Society, Britain's oldest scientific society. His job was to present two or three different experiments each week to the assembled members of the society – and this was at a time when experimentation was new and there were no books of...

A Catalyst article about high-level nuclear waste. It is hot, corrosive and a source of intense radiation. The nuclear industry is seeking safe ways to deal with such waste, and wants the public to help shape the decisions that are made. This article presents some information about the options for the storage of...

A Catalyst article about a Kenyan scientist who is searching for better treatments for malaria, a disease which kills more than a million people in Africa each year. The article also explains some of the challenges of doing science in Africa, where funding is low. Often the illness shows a remarkable ability to...

A Catalyst article about ants. A colony consists of hundreds, even thousands, of ants working diligently and cooperatively, perhaps to kill and carry a large prey item, build a large nest structure or develop and use road-like networks for foraging. Collectively, colonies of social insects can do amazing things and...

The animal kingdom contains an abundance of exquisite natural patterns from the stripes of an angelfish to the spots of a leopard. But how do these arise during early development? This Catalyst article looks at Turing mechanisms as a way of explaining how patterns develop as an animal grows.

In 1952, Alan...

A Catalyst article about the Hubble telescope exploring a barred spiral galaxy, known as NGC1672 in the astronomers’ New General Catalogue. The image was made by the Hubble Space Telescope (HST), and was released in April 2007. NGC 1672 is situated 60 million light years away, in the constellation of Dorado. The...
