Major new research examining the use of virtual surgery could revolutionise the way surgeons are trained in the future.
Experts use to believe that virtual reality, which allows trainee surgeons to feel and see exactly what they would if they were in the operating theatre, may help improve surgical skills, but it hadn’t been proved – until now.
The innovative research, by world experts from Yale University and Queen’s University Belfast, has shown that surgeons who trained o
An international team of researchers leaded by the Universitat Autònoma de Barcelona have found experimental evidence that the various manifestations of fear in animals are influenced by a specific place or region within the genome. The results, published in the latest edition of Genome Research, were obtained with rats, but the scientists suspect that this research will facilitate an understanding of genetic characteristics and conditioning factors related to fear in humans.
Findings from the Anthrax Vaccine Expert Committee (AVEC) do not suggest a high frequency of medically important adverse events associated with anthrax vaccination
Between March 1998 and March 2002 525,000 US military personnel were vaccinated against anthrax. In the case of an outbreak, this vaccine could be extended to civilians, as occurred in December 2001. The Anthrax Vaccine Expert Committee (AVEC), a civilian panel of physicians and scientists set up to monitor the safety of vaccinati
Biotech human breast milk growing but not bottled.
Genetically modified (GM) rice carrying a protein from human breast milk could be used to enhance infant formula, researchers hope. But at present, the protein would not gain approval for use in the United States.
Nutritionists agree that breast milk is best for a baby; infant formula is not as nourishing as the real thing. So for mothers unable to breast-feed, the biotech industry is engineering crops or animals to make huma
Cosmologists claim Universe has been forming and reforming for eternity.
The Universe was not born in one Big Bang, it has been going through cycles of creation and annihilation for eternity, according to a controversial new mathematical model 1 .
Its a compelling claim. The new cyclic model removes a major stumbling block common to existing theories of the Universe – namely, that physics cant explain what came before the Big Bang.
Research, published in the online journal, BMC Biotechnology shows how researchers in Italy have used genetically modified eggplants made by the introduction of a gene that increases the level of the plant hormone indole acetic acid (IAA) to produce seedless fruits. Furthermore, these genetically modified eggplants are 30-35% more productive than conventional varieties in both greenhouse and field trials.
The public have a special liking for seedless fruits for two reasons, firstly seeds a
Far away among the stars, in the Ara constellation of the southern sky, a small black hole is whirling space around it. If you tried to stay still in its vicinity, you couldnt. Youd be dragged around at high speed as if you were riding on a giant flywheel.
In reality, gas falling into the black hole is whirled in that way. It radiates energy, in the form of X-rays, more intensely than it would do if space were still by tapping into the black holes internal energy stream.
Just under one per cent of all Germans suffer from schizophrenia. The susceptibility to contracting this severe psychological disease is inherited; various studies indicate that a gene on chromosome 1 shares responsibility for the outbreak of the disease. However, in what is the biggest control study to date, which is being published in the May edition of the prestigious scientific journal Science, the researchers conclude that the suspect gene plays a less important role than was expected. Centres o
Discarded human debris is encouraging colonization of exotic marine animals in the world`s oceans and threatening global biodiversity, particularly in the Southern Ocean. The findings, reported in this week`s NATURE, are based on a 10-year study of human litter (mostly plastic) washed ashore on 30 remote islands around the globe, from the Arctic to the Antarctic.
David Barnes of the British Antarctic Survey (BAS) found that man-made rubbish in the seas, especially plastics, has almost double
Fossil find hints at life of one of our earliest mammalian forebears.
A mouse-sized fossil from 125 million years ago is the earliest known member of the mammal group that includes humans, say researchers.
The animal is a primitive example of today’s dominant mammals. “It’s at the very root of this diverse and incredibly important group,” says palaeontologist Zhe-Xi Luo of the Carnegie Museum of Natural History in Pittsburgh 1 .
The mammal, Eomaia sc
