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...

With so many research groups across the world, it can be difficult for scientists to keep on top of the latest developments and findings. As well as publishing in journals (such as Nature or Science), researchers communicate their results at scientific conferences. These range in size from small, specialist...

This Catalyst article looks at agricultural plants, that are prone to many diseases, and scientists who develop new techniques to fight these diseases.

This Catalyst article explains why there are many anti-bacterial drugs but few antivirals. There are millions of bacteria everywhere – on skin, in the gut, and on food. Bacteria have been troubling human beings for as long as they have been around, so a lot of effort has been directed into finding ways to fight...

A Catalyst article looking at how living organisms can act as biological indicators of problems in the way the environment is managed. Skylarks and other birds are disappearing from farmland. The article looks at how the statistics have been obtained, how and why bird numbers have declined and what can be done to...
