Some men send flowers, others send chocolates. But one species of fish has a rather unusual method of seducing the opposite sex. Researchers at the Centre of Marine Science, University of Algarve, Portugal, have been studying how the peacock blenny fish secretes pheromones – chemical ‘love’ signals – from an anal gland.

Dr Eduardo Barata observed peacock blenny over the breeding season, when males occupy holes and crevices in the bottom of the sea which they use as nesting sites where female

Life-threatening pneumonia in bone marrow transplant (BMT) patients can be controlled using a strategy called pre-emptive therapy, scientists heard today (Wednesday 10 April 2002) at the spring meeting of the Society for General Microbiology at the University of Warwick.

“We have found that early diagnosis and treatment of colds and flu in transplant and immunocompromised patients can reduce the risk of pneumonia. But pre-emptive therapy is not just a question of providing drugs to patients.

Epilepsy drugs given to women during pregnancy can treble the risk of congenital malformation or developmental delay in their children, finds research in the Journal of Medical Genetics.

Stopping treatment for epilepsy during pregnancy is not an option, but there is an urgent need to develop safer drugs, conclude the researchers. Six in every 1000 pregnancies will be to a woman treated with epilepsy drugs.

There is a strong genetic component to the gluten intolerance disorder, coeliac disease, shows research in Gut.

In the largest study of its kind, Italian researchers studied 47 twin pairs, who were selected on the basis that one belonged to the Italian Coeliac Disease Association (AIC). They were tested for antibodies specific to coeliac disease to ensure that ‘silent’ disease was detected, and their genetic profile was mapped. Tissue samples were taken to confirm changes indicative of the

Using a powerful instrument on a telescope in Hawaii, UK astronomers have found ashes from a generation of stars that died over 10 billion years ago. This is the first time that the tell-tale cosmic dust has been detected at such an early stage in the evolution of the universe.

Dr. Kate Isaak of Cambridge University will be announcing these exciting new results at the National Astronomy Meeting in Bristol on 11th April 2002.

Sustainability may not be all it’s cracked up to be. That is the message in a recent paper by a hydrogeologist at Reading University . Michael Price argues that most human advances have been non-sustainable in the long term and that when we talk of ‘sustainable use’ we must define the period over which the use is planned or implemented.

Price identifies three major challenges currently facing Britain and the world. The first is that the climate, and with it the supply of water, is becoming
