Washington, November 6: Tel Aviv University researchers have written a piece of software that they believe may help reduce hospital-related infections by 50 per cent.

Professor Yehuda Carmeli of the Sackler Faculty of Medicine, who has developed the high-tech software program, says that his security system works by integrating basic sanitary procedures.

He says that the novel system uses the tools of high-tech communication like email alerts, SMS’s, and online communication to alert hospital staff of potential threats.

His team had adopted this system in their own institutions two years ago.

“We stopped forty-five percent of the primary hospital-borne organisms that attack patients from spreading,” says Carmeli.

Washington, November 6: Paris Hilton has pledged that she intends never to go under the knife since she believes it makes one look older.

The hotel heiress, who is presently dating the ‘Good Charlotte’ rocker Benji Madden, revealed that a plastic surgery was an absolute no-no for her.

"I love being all-natural. A lot of girls who are 21, they have a lot of work done and they look 40. It ages you. And you''re going to have to maintain it,” Contactmusic quoted her as saying.

Washington, Nov 6: A new research has indicated that the search for dark matter, a mysterious substance that makes up most of the Universe, could soon be at an end, thanks to a giant computer simulation.

Dark matter is believed to account for 85 per cent of the Universe’s mass, but has remained invisible to telescopes since scientists inferred its existence from its gravitational effects more than 75 years ago.

Now, the international Virgo Consortium, a team of scientists including cosmologists at Durham University, has used a massive computer simulation showing the evolution of a galaxy like the Milky Way to “see” gamma-rays given off by dark matter.

Washington, Nov 6: Men’s risk of developing diabetes can be calculated by factors like their genetic background and behaviour, according to a new study.

While scientists have learned a lot about human disease through research in traditional laboratory mice, there are limits in studying genetic variation since controlled breeding and diet introduces artificially influences.

In order to study diabetes risk in a more naturally genetically diverse animal, Roxanne Oriel, Paul Vrana and colleagues studied glucose tolerance, a test often used to diagnose diabetes and metabolic syndrome, in a type of field mouse native to North America.

Washington, Nov 6: A team of researchers have carried out the largest study of differences between human and chimpanzee genomes, identifying regions that have been duplicated or lost during evolution of the two lineages.

The study is the first to compare many human and chimpanzee genomes in the same fashion.

The team show that particular types of genes - such as those involved in the inflammatory response and in control of cell proliferation - are more commonly involved in gain or loss.

They also provide new evidence for a gene that has been associated with susceptibility to infection by HIV.
