An international team of astronomers has discovered that “dark matter”, the mysterious material that seems to make up most of the mass of galaxies, is not as all-pervasive as previously believed. Surprising new results from studies of several elliptical galaxies show they are not surrounded by halos of dark matter as was expected. The findings will be presented at the UK/Ireland National Astronomy Meeting in Dublin on Wednesday April 9th by Dr Aaron Romanowsky of the University of Nottingham.

An international collaboration between medical researchers may have identified how meningitis causing bacteria cross from the blood into the brain, paving the way for new strategies to prevent this fatal disease, the Society for General Microbiology’s Spring Meeting in Edinburgh heard today, Tuesday 8 April 2003.
“Almost every known bacteria which attacks people could potentially cause meningitis,” says Professor Kwang Sik Kim of John Hopkins University, Baltimore, USA who worked on this issue fo

British children’s lives might be saved by being routinely vaccinated for chickenpox, according to Dr Anne Gershon, speaking at the Society for General Microbiology’s Spring Meeting in Edinburgh today, Wednesday 9 April 2003.

“At the moment British children are not given routine vaccinations. In the USA and Canada one dose against chickenpox is given to children under 13 years old, and two doses are given to older children and adults, which appears to significantly cut down outbreaks of the

A pioneering transport system which uses sophisticated computer technology to provide buses on demand may help to solve rural travel problems.

Passengers using the new service benefit from flexible timetables, can influence the journey routes and may be picked up and dropped off on their doorsteps.

The University of Newcastle upon Tyne’s Transport Operations Research Group (TORG) and Northumberland County Council are jointly managing the three-year £750,000 pilot project, w

The sex of newborns is dictated by the X and Y chromosomes – girls are XX whereas boys are XY. However, new research from Northwestern University has shown that normal testis formation depends on two genes — the so-called male-determining SRY gene, found on the Y chromosome 10 years ago, and a gene called Dax1 on the X (female) chromosome.
Based on the findings of the Northwestern study, published in the May online Nature Genetics, it now appears that Dax1 is required at several points in embr

New research from the University of Alberta has found that an online business can benefit from listing its competitors’ products, even if some of those comparisons are unfavourable for the firm.

Dr. Gerald Haeubl, the Banister professor of electronic commerce at the U of A’s School of Business, investigated how digital agents, such as the Internet, influence the online shopping experience. Surprisingly, he found that when a company lists its competitors’ prices of identical products—even if
