In Brief : Mating frenzy

THE synchronous rhythms of chorusing frogs and crickets are the result of frenzied competition to find mates, according to scientists at the University of Kansas.

Opinion

Editorial : The means to an end – Alternatives to animal experiments are possible, but governments must pay

IT IS every scientist's responsibility to avoid the unnecessary use of animals in experiments—there is nothing contentious about that. Governments everywhere generally support that view and reams of legislation seek to protect animals. But while there is broad agreement on ethical issues, there remain huge questions for scientists on the extent to which animals could …

Highs and lows – Heroin really screws up your immune

NEXT time you drink up or if you're crazy enough to spliff up or shoot up, be prepared for some unwelcome bodily changes. And we're not talking constipation, freaky hallucinations, or the midnight munchies here. Evidence is mounting that certain illicit and recreational drugs like heroin, alcohol and marijuana subvert the body's natural defence mechanisms, …

Review : Collected works – Elizabeth Sourbut travels far and wide with

LOCATION, characters and technology are all important aspects of any science fiction novel. Occasionally the three are held in a tidy dynamic balance, but it's a hard thing to do well. Bart Kosko veers too far towards technology. He is better known for nonfiction writing, and in Nanotime (Avon, $24, ISBN 0380974665) he pays little …

Feedback

WHAT DOES the word "safety" mean to the younger generation? The Green Cross Code man, perhaps, who ensures that children cross roads safely? Apparently not. Michael Francis's 11-year-old son had his first laboratory lesson at the beginning of this autumn term. The class was shown a video, Safety in the Laboratory, which emphasised the importance …
