Scientists from Imperial College London have suggested why the human genome may possess far fewer genes than previously estimated before the human genome project was begun.
Research published in the July issue of Trends in Immunology, shows how a more advanced immune system in humans could explain why the human genome may have only a slightly greater number of genes than the plant Arabidopsis thaliana, and probably less than rice, Oryza sativa.
Dr Andrew George, from Imperial College London and based at the Hammersmith Hospital comments: “Although humans are normally thought to be considerably more complex than organisms, such as plants, rice, yeast and earthworms, this is not reflected in their number of genes, with humans having less genes than other supposedly less complex organisms.”

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
