Doctors call for balancing of patient/carer viral transmission protection.
Healthcare staff are at a much higher risk of acquiring viral infections from infected patients than vice versa. These viral infections include HIV and hepatitis. Despite this, patients receive enormous protection, while staff could be left exposed. A paper published this week in the British Journal of Surgery recommends that good medical care of... view more... (2004-03-15)
NIAID scientists propose new explanation for flu virus antigenic drift
Influenza viruses evade infection-fighting antibodies by constantly changing the shape of their major surface protein. view more (2009-10-30)
Sick Beans lead to Nanotech
Farmers get little joy from the cowpea mosaic virus, which attacks legumes. Chemists and molecular biologists at the Scripps Institute in La Jolla are, on the other hand, completely taken with this virus. They are not setting the tiny things loose on plants, however, but have something completely different in mind: the viruses are to act as... view more... (2002-01-22)
Imitating monkey's 'jumping genes' could lead to new treatments for HIV
UCL (University College London) scientists have taken a significant step in understanding how retroviruses such as HIV can move between species and the biological mechanisms behind the 'jumping genes' which make some monkeys immune. They will now use this knowledge to develop a gene therapy treatment for HIV/AIDS in humans. view more (2008-02-19)
Scientists force viruses to evolve as better delivery vehicles for gene therapy
Viruses and humans have evolved together over millions of years in a game of one-upmanship that, often as not, left humans sick or worse. view more (2006-02-08)
Matrix protein key to fighting viruses
Researchers from Durham University's Centre for Bioactive Chemistry are developing methods that show how proteins interact with cell membranes when a virus strikes. view more (2009-04-29)
A viral cloaking device
Viruses achieve their definition of success when they can thrive without killing their host. Now, biologists Pamela Bjorkman and Zhiru Yang of the California Institute of Technology have uncovered how one such virus, prevalent in humans, evolved over time to hide from the immune system. view more (2008-07-21)
Alaska avian flu project issues initial surveillance results
So far, so good. Although only a few of the results are in, the University of Alaska Program on the Biology and Epidemiology of Avian Influenza in Alaska reports today that none of the samples taken from migratory waterfowl in the state this summer and screened to date have tested positive for the deadly H5N1 strain of bird flu virus being... view more...

New way to make stem cells avoids risk of cancer
A team of scientists has advanced stem cell research by finding a way to endow human skin cells with embryonic stem cell-like properties without inserting potentially problematic new genes into their DNA. view more (2009-03-27)
Out of the blue"¦press conference invitation
Deep-sea microbiology could soon be helping to restrain antibiotic-resistant infections like MRSA, the hospital 'superbug', according to research results to be announced at a conference in Edinburgh on Tuesday 24 May. view more (2005-05-18)
'Jumping genes' could make for safer gene delivery system
To move a gene from point A to point B, scientists and gene therapists have two proven options: a virus, which can effectively ferry genes of interest into cells, and a plasmid, an engineered loop of DNA that can do the same thing, albeit usually only on a short-term basis. view more (2007-09-27)
Details of the life cycle of SARS coronavirus
A team of scientists studying Severe Acute Respiratory Syndrome (SARS) has, for the first time, described how the SARS virus manufactures several of the materials required for making copies of itself. "It is essential, when you are looking for ways to stop a disease, that you know exactly how viruses make copies of themselves and... view more... (2003-07-08)
Structure of viral harpoon protein reveals how viruses enter cells
A team of Northwestern University researchers has solved the structure of a molecule that controls the ability of viruses of the paramyxovirus family, including the viruses that cause measles, mumps, and many human respiratory diseases, to fuse with and infect human cells. view more (2006-01-05)
UK Scientists Create Medical And Food Safety Tool From Virus
UK scientists have found a way to explode deadly food-poisoning bacteria using an agent found in viruses. Professor Mike Gasson from the Institute of Food Research in Norwich discovered the potential of viruses while researching flavour development in cheese in the early 1990s. And with the help of Profos AG, an international company specialising... view more... (2003-12-18)
HIV Infection Stems From Few Viruses
A new study reveals the genetic identity of human immunodeficiency virus (HIV), the version responsible for sexual transmission, in unprecedented detail. view more (2008-05-16)
Discovery could lead to better control of hemorrhagic fever viruses
Researchers report discovering the receptor through which a group of life-threatening hemorrhagic fever viruses enter and attack the body's cells, and show that infection can be inhibited by blocking this receptor. view more (2007-02-08)
New treatment model for HIV
Treatment of HIV patients must balance the need to suppress viral replication against the harmful side effects and significant cost to the patient of antiretroviral therapy. view more (2007-07-13)
Mouse study reveals new clues about virulence of 1918 influenza virus
The first comprehensive analysis of an animal's immune response to the 1918 influenza virus provides new insights into the killer flu, report federally supported scientists in an article appearing online today in the journal Nature. view more (2006-09-29)
Silver bullet: UGA researchers use laser, nanotechnology to rapidly detect viruses
Waiting a day or more to get lab results back from the doctor's office soon could become a thing of a past. Using nanotechnology, a team of University of Georgia researchers has developed a diagnostic test that can detect viruses as diverse as influenza, HIV and RSV in 60 seconds or less. view more (2006-11-16)
Revolutionary room-specific air-filtering of pollutants, nerve gases and viruses
VTT Technical Research Centre of Finland and Lifa Air Oy Ltd have jointly developed a room filter that traps particles, toxic gases, bacteria and viruses in the incoming air. Low-priced and energy-efficient, the filter can be fitted in the existing air-conditioning systems. Room-specific filtering of inlet air has been attracting increasing... view more... (2003-10-20)
