Superconductors: Powering the Future, Probing the Past
A Catalyst article about the many uses of superconductors. The article looks at what the 1700 magnets at the Large Hadron Collider and power cables in Detroit have in common. Both use superconductors - materials which, when cooled below a certain temperature, lose all their electrical resistance, and display some...
Superman's Not Dead
This Catalyst article investigates x-rays. X-rays are used in security scanning and medical diagnosis. Efforts are always being made to reduce the hazard of working with these electromagnetic rays.
The article is from Catalyst: Secondary Science Review 2014, Volume 25, Issue 2.

Talkative Microbes
This Catalyst article explores how microbes communicate and how, by growing two different microbes together, it is possible to discover new substances which may be useful in medicine. Microbial communication happens by small bioactive molecules which the cells release into and receive from the environment. In this...
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? When cattle are found to be suffering from tuberculosis, a disease which can be passed onto humans, they are routinely slaughtered. It is known that badgers can transmit the...

Ten Years On: the Human Genome Project Today
This Catalyst article looks at how our knowledge of the human genome has increased greatly during the last 10 years, and genome sequencing techniques have become much faster. On 26th June 2000 it was announced that scientists had completed a first draft of the human genome, the DNA instructions for making a human...
Testing New Medicines *suitable for home teaching*
A Catalyst article exploring the testing of new medicines to see if they are safe for people to take. The effects on cells of a potential new drug are investigated using tissue cultures of human or animal cells. Some tissue cultures use fresh tissue samples, but most come from well-established laboratory cell...
