This issue of Catalyst includes the following articles:
This articles looks at the methods used to detect if there is life elsewhere in the universe.
Gas or electric? What’s best for cooking? Many people prefer gas because it is quick and easy to control. Can the latest electric hobs, ovens and grills compete?
This article explains homeostasis and how it enables mammals and birds to be active whatever the weather.
As plants grow they remove compounds of nitrogen, phosphorus and potassium from the soil which need to be replaced to maintain the soil’s fertility. For centuries farmers have used organic manures, crop rotation or ploughed in specially grown crops; the current use of chemical fertilisers is explained.
Catalyst is a science magazine for students aged 14-19 years. Annual subscriptions to print copies of the magazine can be purchased from Mindsets.
