Preparing for the Venus Express

The European Space Agency is planning its first mission to unveil the mysteries of Earth`s cloud-shrouded sister planet, Venus. On Wednesday 10 April, Professor Fred Taylor (University of Oxford) will be explaining to the UK National Astronomy Meeting why European scientists are hoping to be on board the Venus Express in 2005.

Venus, the Earth`s nearest planetary neighbour, is remarkably similar in size and mass to our own world. However, its atmosphere and climate could hardly be more diff

HIV in the nervous system – still a cause for concern?

HIV infection can be controlled with antiretroviral drugs, but it cannot be wiped out. New evidence suggests that low levels of HIV may still lead to long-term brain damage and dementia, scientists heard today (Tuesday 09 April 2002) at the spring meeting of the Society for General Microbiology at the University of Warwick.

“There is concern for the longer term outlook of treated patients because of the likely presence of a low grade inflammation of the brain. Infected drug users are at grea

Bacteria change ‘fingerprints’ and baffle detectives

Tracing the source of a campylobacter food poisoning outbreak can be very difficult even with modern DNA fingerprinting methods. There is now evidence that campylobacters can rearrange their DNA, disguising their fingerprint, and confusing such detective work, scientists heard today (Tuesday 09 April 2002) at the spring meeting of the Society for General Microbiology at the University of Warwick.

Professor Diane Newell and her colleague Dr Anne Ridley of the Veterinary Laboratories Agency sa

Going Ballistic: Soft Structures Could Spell The End For Slow Shrimps

Many animals are able to rapidly extend their tongues to catch prey. In fact, the chameleon extends its tongue at an acceleration rate of 500 metres per second square – generating 5 times the G force experienced by an F-16 fighter during its most demanding maneouvre! New research presented at the Society for Experimental Biology conference in Swansea today has shed light on exactly how these remarkable feats are achieved.

Dr Johan van Leeuwen of Wageningen University, the Netherlands, sugges

Sporty Sperm: A Stiff One Gets the Job Done More Quickly

A scientist who studies the phsyics of sperm “as a hobby” is challenging the current understanding of how sperm swim towards an egg. At the Society for Experimental Biology conference today Dr Christopher Lowe will present the results of his modelling of a sperm`s tail, suggesting we may need to re-think our assumptions of how sperm move through fluid.

Experimental studies of sperm have generated a fairly well established database of parameters on sperm movement. The frequency and wavelength

Shelf-Life Science: Good Genes Could Stop Broccoli Going Bad

Broccoli is one of western Europe`s most popular and widely consumed vegetables. However, its shelf life is restricted to about 5 days at room temperature, making distribution and storage of the product difficult. Recent research presented today at the Society for Experimental Biology conference in Swansea could help us understand the genetics of this situation and may even lead to `supervarieties` of broccoli.

The popularity of broccoli is on the increase and it is used increasingly in valu
