Time is running out for the clocks that make our computers tick. Scientists have developed a new generation of hardware and software based on the simpler designs of the 1950s.

Asynchronous, or clock-free systems, promise extra speed, safety, security and miniaturisation. The new designs work well in the laboratory and are only awaiting the development of software tools so that they can be produced commercially, says Professor Alex Yakovlev and fellow researchers in the Department of Computin

Scots scientists are playing a key role in a major new research effort which could save Britain’s farmers millions of pounds a year through reductions in fertiliser and pesticide use.

Biotechnology experts at the University of Abertay Dundee, in partnership with two organisations in England, have been awarded £471,000 by the BBSRC (Biotechnology and Biological Sciences Research Council) for a three-year study into the relationship between white clover and a tiny insect.

Researchers at Cambridge University have been studying the process of gene silencing in transgenic plants, and have cloned a genetic modifier that could reduce transgene instability. Dr Ian Furner will be presenting the results of the study at the Society for Experimental Biology conference on Monday 8 April.

Gene silencing is a naturally occurring process by which genes can become shut off within a plant. When transgenes are introduced into plants they can also show gene silencing. Genes wh

The ability of meningococci bacteria to change their cell surface proteins could reduce the effectiveness of the current meningitis C vaccine. Now scientists are working on vaccines that would allow us to co-exist happily with these microbes, according to research presented today (Monday 08 April 2002) at the spring meeting of the Society for General Microbiology at the University of Warwick.

“We have identified several proteins secreted by meningococci, which are involved in causing diseas

A vaccine has been developed, which could prevent inflammation and illness caused by certain bacterial infections following major surgery, scientists heard today (Tuesday 09 April 2002) at the spring meeting of the Society for General Microbiology at the University of Warwick.

Dr Elliott Bennett-Guerrero, Chief of Cardiac Anesthesia at Columbia University College of Physicians & Surgeons, New York, USA says, “Severe inflammation caused by bacterial toxins is becoming recognised as an importa

Signs of virus from human faeces found in bottled water.

Mineral water is marketed for its purity. But Swiss scientists are claiming that some brands may be contaminated with human faeces.

In 11 of 29 European brands of bottled mineral water Christian Beuret and colleagues of the Cantonal Food Laboratory in Solothurn found signs of the virus that causes more than 90% of the world’s stomach upsets 1 , 2 . The virus is called Norwalk-like virus
