Catalyst Volume 20 Issue 3
This issue of Catalyst includes the following articles:
Molecules From the Past
This article shows how analysing molecular residues in ancient objects helps to reveal how people and animals once lived.
When the Drugs Don't Work
The article investigates why there are many anti-bacterial drugs but few antivirals.
How Science Works in Africa
The work of a Kenyan scientist searching for better treatments for malaria is the main focus of this article.
Small Wonders: the Invention of Microscopy
The article describes the work of early microscopists such as Leeuwenhoek, Hooke and Swammerdam.
Solar Cells
Devising better, more energy-efficient solar cells is the main subject of this article.
LEDs: Lighting Up a Brighter Future
Like food, water, clothing and shelter, light is essential to people's lives. This article describes the latest, energy-efficient lighting technologies.
Encounters with Aliens - Invasive Species
This article looks at one of the consequences of international trade and travel that is an increase in the movement of so called alien species around the world. Invasive alien species, alongside climate change and habitat destruction, are considered to be one of the main drivers of biodiversity loss. This article asks: what are alien species and what threats do they pose?

HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment.
Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date.
Since that time there have been significant changes in the rules and guidance affecting laboratory practical work.

Molecules From the Past
A Catalyst article looking at how modern archaeology uses analytical chemical techniques to answer questions about ancient civilisations and animals. Scientists working at the University of Bristol match compounds present in archaeological materials to those in modern plants and animals which were likely to have been used in ancient…
When the Drugs Don't Work
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 back at them. This…
How Science Works in Africa
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 select for resistance…
Small Wonders - the Invention of Microscopy
A Catalyst article about the early microscopists, including Leeuwenhoek, Hooke and Swammerdam. Their work looked at the miniature world beyond human sight and through publications raised awareness of phenomena such as how insects functioned and how disease spread. The article also examines the use of simple and compound microscopes. This…
Solar Cells
This Catalyst article investigates the development of better, more energy-efficient solar cells. Every minute enough sunlight strikes the Earth to power our civilisation for a year, yet less than 1% of global energy generation is provided by solar energy. Solar cells convert sunshine directly to electricity, but to make them more…
LEDs - Lighting Up a Brighter Future
A Catalyst article about devising better, more energy-efficient lighting. In particular the article focuses on LEDs. Like food, water, clothing and shelter, light is essential to daily life and is needed by most people for most of their waking hours. The article explains how LEDs work and how they are made. This article is from…
Encounters with Aliens - Invasive Species
This Catalyst article looks at harlequin ladybirds, just one of the invasive species that has spread through Western Europe. Over the last century there has been a dramatic increase in the movement of so called alien species around the world as a consequence of international trade and travel. Invasive alien species, alongside climate…
