Catalyst Volume 24 Issue 2
This issue of Catalyst contains the following articles:
This article looks at types of parasitic plants and how they derive their nutrients from the root systems of other plants.
This article looks at how geothermal energy is derived from hot rocks below the Earth's surface and can be used for heating or to generate electricity.
Music technologist Jez Wells explains how electronic systems can produce sounds which merge the qualities of different musical instruments.
This article looks at the work of Alfred Russel Wallace who developed a theory of evolution in parallel with Charles Darwin.
This article explores how microbes communicate and how, by growing two different microbes together, it is possible to discover new substances which may be useful in medicine.

The World of Parasitic Plants
Most people are all too familiar with the idea of animal parasites, including tape worms, ticks and lice. But did you know that plants can also act as parasites, exploiting resources from unwilling hosts? Rather than being rare anomalies, however, there are over 4000 known species of parasitic plants, with...
What Is Geothermal Energy?
Geothermal energy is the heat produced by decay of radioactive isotopes deep within the Earth. The temperature at the centre of the Earth is thought to be around 5,000°C, with the temperature reducing toward the surface. It is estimated that 99.9% of the planet is above 100°C. Geothermal energy is considered a...
Sonic Husbandry
Electronic musical instruments are getting better and better at mimicking and behaving just like their acoustic counterparts, but they can also create a wealth of sounds that would be difficult or impossible to achieve with acoustic instruments. In this Catalyst article, Jez Wells, a music technologist, explains...
Alfred Russel Wallace
This Catalyst article looks at the work of Alfred Russel Wallace who developed a theory of evolution in parallel with Charles Darwin; they published their findings jointly. As a scientist he was interested in lots of different things, from how different species came into existence to the question of whether ghosts...
