A Catalyst article about whaling. During the last century whales were hunted and killed by many nations for the valuable materials they provided. Whale populations collapsed as a result. The article looks in detail at this example of human impact on the environment and details whale populations throughout the world...

This Catalyst article explains the use of stem cells to treat medical problems, and outlines new possibilities for the use of adult stem cells in treatment.

Currently, stem cells used for treatment are embryonic stem cells, since they have the ability to form any cell type in the body. The example of the use...

This article from Catalyst looks at aurora borealis caused by the interaction of the solar wind with the Earth's magnetic field. It also explains how satellites are testing thoeires of how this happens. Auroral light emission occurs at roughly 100 km altitude. Energetic electrons in the solar wind cause the...

This Catalyst article looks at Biochemistry, the study of chemical reactions in living things, exploring how it differs from other biological subjects and how examples can be found in everyday life.

This article is from Catalyst: Secondary Science Review 2011, Volume 22, Issue 2.

A Catalyst article about the many roles of chemists at work. The links with biology, physics and geology are examined as are many other subjects. The article looks at some of the areas in which chemists work and it explores what makes it distinctive from other sciences.

This article is from Catalyst:...

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 discusses what physics is. Physics is a subject which seeks to answer fundamental questions about the nature of matter and the Universe in a self-consistent way.

This Catalyst article explores where Science Communication came from, how it has grown and why it has an important role to play in helping people to learn about science.

On one level Science Communication is about communicating science and building bridges between the people involved in scientific research...

This Catalyst article explores analytical science which is the branch of chemistry concerned with determining which substances are present in a sample and how much.

This Catalyst article explores the complex structure of cells, and numerous theories of how they were formed. It describes how the development of electron microscopes has allowed greater detail of cellular strutures and organelles to be understood. The article includes detailed electron micropgraphs, along with...

A Catalyst article about the naming system used for biological species, devised by Linnaeus. The purpose of biological names is investigated and the article also explains how the naming system works.

This article is from Catalyst: Secondary Science Review 2009, Volume 19, Issue 3.

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...
