A virtual reality Underground ride has been used by researchers to reveal the extent that paranoia occurs in the general public. The research, funded by the Wellcome Trust, demonstrates that suspicious or paranoid thoughts are much more common in the general population than was previously thought and that they are almost as common as anxiety and depression.
The climate changing gas dimethyl sulphide (DMS) is being made by microbes at the rate of more than 200 million tonnes a year in the worlds seas, scientists heard today (Tuesday 1 April 2008) at the Society for General Microbiologys 162nd meeting being held this week at the Edinburgh International Conference Centre.
Fruit-eating birds actively select fruit with the highest concentrations of antioxidants compounds that help them maintain a healthy immune system ecologists have found. This is the first time that a group of antioxidants known as flavonoids have been found to boost the immune system in studies on living animals, as opposed to test-tube studies. The results are published online in the British Ecological Societys Functional Ecology.
Medical scientists from the University of Leicester, together with colleagues from St Georges, University of London, funded principally by the Medical Research Council (MRC) and The Wellcome Trust, have published details of a new breakthrough discovery on TB.
They have identified for the first time that the TB bug lays down body fat that may help it survive passing from one person to another and, in the process, the bacteria increase their resistance to the action of anti-TB drugs.
The simple act of running in an exercise wheel delays the onset of some symptoms of Huntingtons disease in a mouse model of the fatal human disorder according to research published in the open-access journal BMC Neuroscience. These findings add insights into the pathogenesis of the disease and suggest possible preventive therapeutic targets.
Researchers have discovered how Human Immunodeficiency Virus (HIV), which causes AIDS, can hide itself in our cells and dodge the attention of our normal defences, scientists heard today (Tuesday 1 April 2008) at the Society for General Microbiologys 162nd meeting being held this week at the Edinburgh International Conference Centre.
AIDS, a fatal disease in humans, may partly be the consequence of an evolutionary accident, scientists heard today (Tuesday 1 April 2008) at the Society for General Microbiologys 162nd meeting being held this week at the Edinburgh International Conference Centre.
AIDS is a deadly disease in people that is caused by human immunodeficiency virus (HIV). But similar viruses such as simian immunodeficiency virus (SIV), which infects monkeys, usually dont cause disease in their natural monkey hosts, says Professor Frank Kirchhoff from the University of Ulm in Germany.
New Haven, Conn. — Higher organisms do not have a cost of complexity — or slowdown in the evolution of complex traits — according to a report by researchers at Yale and Washington University in Nature.
Biologists have long puzzled over the relationship between evolution of complex traits and the randomness of mutations in genes. Some have proposed that a cost of complexity makes it more difficult to evolve a complicated trait by random mutations, because effects of beneficial mutations are diluted.
WEST LAFAYETTE, Ind. - Engineers have created the first "active matrix" display using a new class of transparent transistors and circuits, a step toward realizing applications such as e-paper, flexible color monitors and "heads-up" displays in car windshields.
(WASHINGTON, March 31, 2008) Survival rates of childhood cancers, especially leukemia, have improved greatly in the past three decades, but survivors of this disease still seem to face many health and lifestyle challenges as young adults. Depending on the extent of their disease and treatment methods, many continue to struggle with one or more life-long medical conditions and decreased quality of life, according to a study prepublished online in Blood, the official journal of the American Society of Hematology.
