Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine.

This issue of the Big Picture, from the Wellcome Trust, looks at the role that food plays not only in human physiology but also in the individual's lives. Food is about so much more than sustenance. Food choice...

A Catalyst article looking at how insects are used to provide clues at crime scenes. Forensic entomology is the study of insects and other arthropods in a legal context. It covers many different areas, such as pests in stored food products and insect infestations in human habitations. However, the most high-profile...

A Catalyst article about scientists who are only beginning to understand just how complex and fascinating the relationship between trees, the carbon cycle and climate really is. This article explores how aspects of the GCSE science course relate to the latest research. It also covers the relationship between trees...

This Catalyst article investigates the research into artificial photosynthetic systems.

With the world’s population ever-expanding, energy demand is expected to double by 2050 and triple by 2100. In only 200 years, mankind has squandered what nature has taken hundreds of millions of years to lay down as...

Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine. The Earth's climate is changing ever faster, and human activities play a role in speeding up this change.

The Earth’s climate is changing. In fact, it has always been...

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...

Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine. This issue looks at the interplay between the biology that sculpts our form and the culture that interprets and adapts it.

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...
