The phrase `rain stopped play` is gloomily familiar to fans of Wimbledon, international cricket test matches and other major sporting tournaments.

But cancelling matches because the pitch is waterlogged could be consigned to history, thanks to new technology which could revolutionise the international world of both professional and amateur sport.

Researchers at the University of Newcastle upon Tyne are starting trials involving a completely new concept – Electrokinetic Geosynthetic

Researchers studying plant behaviour have discovered similarities between the processes preventing plants from wilting and humans from suffering impotence. Data recently published by the University of the West of England shows the same chemical chain of events is involved in both situations – and has led to an understanding of how water loss from plants might be reduced.

This blocking action has parallels with the chemical effect of impotence treatments in humans. Plants lose water through

Miniature floating craft can be programmed to move and assemble in complex ways.

Harvard chemists are playing with bath toys. Floating bubble-powered craft designed to attract and repel one another, are helping them model the machinations of groups such as foraging ants, nest-building termites or schools of fish 1 .

Group dynamics are not always obvious from individuals’ behaviour, but emerge from their interactions. Computer models can simulate such processe

It is possible to measure levels of the stress hormone cortisol not only in blood but also in saliva. Linköping physician Elisabeth Aardal-Eriksson has further developed a saliva test to make it reliable and easy to use, not only in hospitals but also in the field. The findings are presented in a dissertation at Linköping University, Sweden. The researcher has also found that the corisol content of saliva is related to the occurrence of so-called posttraumatic symptoms of stress.

Christiaan Huygens` observations in 1665 of anti-phase synchronisation in two pendulum clocks were the subject of some of the earliest deliberations of The Royal Society but have remained a scientific puzzle. Huygens` acute observations are often quoted but have never been adequately explained – until today. The forthcoming issue of Proceedings A, a Royal Society journal, offers a simple and compelli

The widely held parental belief that asthma inhalers cause hyperactivity in children is not confirmed by research published in the Archives of Disease in Childhood.

The researchers studied 19 asthmatic children between the ages of 2 and 5, all of whom were treated with fast acting reliever inhalers/nebulisers containing salbutamol. The children were being seen at the children’s respiratory clinic at Guy’s and St Thomas’ Hospital, London.

Before being tested, the children’s hyperacti
