TB or not TB?

A Catalyst article about the problems of badgers transmitting tuberculosis to cattle, but is a cull of badgers a solution to the problem? t is known that badgers can transmit the disease to cattle, so many farmers would like to see badgers culled. But is this the solution to the problem? A scientific study suggests that it is not.

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.

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.

Essential Oils as Antimicrobial Agents

Since the discovery of antibiotics, many people believe that the pathogenic microorganism threat to the population has been removed, with fatal infections and infectious diseases brought under control. This has discouraged research into drugs containing natural compounds such as essential oils. This Catalyst article looks at how a school microbiology club investigated the antimicrobial effects of some essential oils.

Seeing Into Bacteria

This Catalyst article describes how biophysics is helping in the search for novel antibiotics. Bacteria produce an array of proteins to kill off their competitors. These proteins, called bacteriocins, are very efficient at penetrating the defensive outer layers of bacteria cells by moving through specific membrane transporter proteins.
