Researchers examine role of climate change in disease spread
Ever since scientists first proposed that our planet might be experiencing widespread climate change, concerns have been raised about its implications for the spread of arboviruses - viruses carried by arthropods such as mosquitoes, midges and ticks. view more (2009-02-06)
Discovery of the origin of the Simian Immunodeficiency Virus (SIV) in the chimpanzee
The origin of HIV-1 (human immunodeficiency virus-1), responsible for the global Aids pandemic, has been a live issue in the scientific community for many years. It is now recognized that HIV-1 in the human population results from cross-species transmission of SIVcpz, from chimpanzees (Pan troglodytes troglodytes) to humans, most likely through... view more...

New Window Opens on the Secret Life of Microbes: Scientists Develop First Microbial Profiles of Ecosystems
Nowhere is the principle of "strength in numbers" more apparent than in the collective power of microbes: despite their simplicity, these one-cell organisms--which number about 5 million trillion trillion strong (no, that is not a typo) on Earth--affect virtually every ecological process, from the decay of organic material to the... view more...

Converting adult somatic cells to pluripotent stem cells using a single virus
A Boston University School of Medicine-led research team has discovered a more efficient way to create induced Pluripotent Stem (iPS) cells, derived from mouse fibroblasts, by using a single virus vector instead of multiple viruses in the reprogramming process. view more (2009-01-08)
New hybrid virus provides targeted molecular imaging of cancer
Researchers at The University of Texas M. D. Anderson Cancer Center have created a new class of hybrid virus and demonstrated its ability to find, highlight, and deliver genes to tumors in mice. view more (2006-04-24)
The structure of a giant virus
The mimivirus is the largest virus known to scientists, about half of a micrometre (0.0005 millimeter) in diameter. It is more than 10 times larger than the virus that causes the common cold and - unlike other viruses - is large enough to be seen with a light microscope. view more (2009-04-28)
Researchers recreate SARS virus, open door for potential defenses against future strains
Researchers at the University of North Carolina at Chapel Hill and Vanderbilt University Medical Center have synthetically reconstructed the bat variant of the SARS coronavirus (CoV) that caused the SARS epidemic of 2003.

H5N1 threat puts human flu back in spotlight
The emergence of the avian influenza virus H5N1 that is currently devastating chicken flocks in many countries and threatening to unleash a worldwide epidemic among humans has triggered a renewed interest among scientists in studying influenza A viruses. view more (2006-05-05)
BRIGHT SPARKS AT THE ROYAL INSTITUTION
Royal Institution SET99 events for schools cover many different topics including Bright Sparks of the Universe (17 March) a presentation about the electron by Professor Frank Close of the Rutherford Appleton Laboratory and Dr Bryson Gore, one of the Royal Institution's most experienced lecturers. Before that there will be a fascinating explanation... view more... (1999-03-02)
A new analysis suggests that schizophrenia may be caused by an interaction of genes and viruses in glia cells
A report in the open access journal BMC Psychiatry presents a new hypothesis that may explain the causes of the psychiatric disease, schizophrenia. The hypothesis hinges on glia, a special type of cell, which is important for the maintenance of the connections between brain cells. By re-examining previously published research the authors suggest... view more... (2002-07-25)
HIV-1 : RECOMBINATION BETWEEN TWO STRAINSFROM WIDELY DISTANT GROUPS
Scientists have known for a long time that the AIDS virus is genotypically highly variable. Two main types of the virus exist: HIV-1 and HIV-2. HIV-1, the most widespread throughout the world, can be divided into three groups (M, N and O) each of which has different genetic characteristics. Within group M, which gathers together the most frequent... view more... (2000-03-09)
Mutation protects from HIV - and increases risk of hepatitis C
More than 40 million people worldwide are infected with the human immunodeficiency virus HIV. In Africa alone this incurable immune deficiency caused more than two million deaths last year. Yet some people are resistant to infection: the reason for this is a mutation in their DNA which prevents the HIV virus from invading certain immune cells and... view more... (2002-07-17)
Scientists develop mathematical model to predict the immune response to influenza
Researchers at the University of Rochester have developed a mathematical model to predict immune responses to infection with influenza A viruses, including novel viruses such as the emergent 2009 influenza A (H1N1). view more (2009-05-14)
Discovery in plant virus may help prevent HIV and similar viruses
In a study that could lead to new ways to prevent infection by human immunodeficiency virus (HIV) and similar organisms, Purdue University researchers have been able to genetically modify a plant to halt reproduction of a related virus. view more (2007-08-01)
Earlier flu viruses provided some immunity to current H1N1 influenza, study shows
University of California, Davis, researchers studying the 2009 H1N1 influenza virus, formerly referred to as "swine flu," have identified a group of immunologically important sites on the virus that are also present in seasonal flu viruses that have been circulating for years. view more (2009-10-15)
Study findings show infection control intervention helps keep kids in school
A study from researchers at Children's Hospital Boston published in Pediatrics found that a simple infection control intervention in elementary schools - disinfecting frequently-touched surfaces and using alcohol-based hand sanitizers - helped reduce illness-related student absenteeism. view more (2008-06-02)
Virus-resistant grapevines
A good wine needs to ripen. But it's a long way to the barrel. Even before the harvest, the grapevines have to overcome all kinds of obstacles. Extremely hot or rainy periods can destroy entire crops, not to mention the wide variety of pests that can appear on the scene. view more (2009-07-06)
New details on how the immune system recognizes influenza
Drawing upon a massive database established with funds from the National Institute of Allergy and Infectious Diseases (NIAID), one of the National Institutes of Health (NIH), scientists have completed the most comprehensive analysis to date of published influenza A virus epitopes-the critical sites on the virus that are recognized by the immune... view more...

Study Implicates Human Coronavirus As Main Cause Of SARS
Early online publication: Tuesday 8 April 2003 FOR IMMEDIATE RELEASE Research from Hong Kong fast-tracked for publication on THE LANCET's website--www.thelancet.com--provides evidence that a new virus belonging to the family Coronaviridae is likely to be the main cause of Severe Acute Respiratory Syndrome (SARS). Malik Peiris from the University... view more... (2003-04-08)
Tomorrow's green nanofactories
Viruses are notorious villains. They cause serious human diseases like AIDS, polio, and influenza, and can lead to system crashes and data loss in computers. view more (2007-07-10)
