Tumor-killing virus selectively targets diseased brain cells
New findings show that a specialized virus with the ability to reproduce its tumor-killing genes can selectively target tumors in the brains of mice and eliminate them. view more (2008-02-20)
Swine flu genes dissimilar to past pandemics
Some genetic markers of influenza infection severity have been identified from past outbreaks. Researchers have failed to find most of these markers, described in the open access journal BMC Microbiology, in samples of the current swine-flu strain. view more (2009-05-07)
Drugs against winter vomiting disease one step closer
The virus that causes winter vomiting disease invades cells by attaching to particular sugar molecules on the surface of the cells. view more (2009-06-11)
Penn Study Identifies How Ebola Virus Avoids the Immune System
Researchers at the University of Pennsylvania School of Medicine have likely found one reason why the Ebola virus is such a powerful, deadly, and effective virus. Using a cell culture model for Ebola virus infection, they have discovered that the virus disables a cellular protein called tetherin that normally can block the spread of virus from... view more...

Mayo researchers discover how measles virus spreads (in its host)
Measles, one of the most common contagious diseases, has been thought to enter the body through the surface of airways and lungs, like many other major viruses. view more (2008-06-23)
Iowa State chemists track how drug changes, blocks flu virus
An anti-virus drug attacks influenza A by changing the motion and structure of a proton channel necessary for the virus to infect healthy cells, according to a recently published research paper by two Iowa State University chemists. view more (2008-02-04)
HIV pays a price for invisibility
Mutations that help HIV hide from the immune system undermine the virus's ability to replicate, show an international team of researchers in the April 13 issue of the Journal of Experimental Medicine. view more (2009-04-13)
Scientists detect presence of marburg virus in african fruit bats
A collaborative team of scientists reported findings today demonstrating the presence of Marburg virus RNA genome and antibodies in a common species of African fruit bat (Rousettus aegyptiacus). view more (2007-08-22)
The effects of climate change on the physiology of alfalfa
The biologist Gorka Erice Soreasu, a researcher in the Department of Plant Biology of the University of Navarra, has studied the effects of climate change on the physiology of alfalfa. view more (2006-04-12)
Salt of the Earth
A yeast gene responsible for salt tolerance has successfully been used to grow tobacco in a salty environment lethal to most plants. Dr Janey Henderson and Professor Phil Harris from Coventry University inserted the halotolerance gene HAL1 from yeast into a tobacco plant. HAL1 has previously been shown to confer salt tolerance in transgenic tomato... view more... (2001-04-04)
Penn scientists find a protein that inhibits Ebola from reaching out to infect neighboring cells
Scientists at the University of Pennsylvania School of Veterinary Medicine have identified a protein, ISG15, that inhibits the Ebola virus from budding, the process by which viruses escape from cells and spread to infect neighboring cells. view more (2008-03-04)
Too Much of a Good Thing: Understanding Plants' Overactive Immune System Will Help MU Researchers Build Better Crops
A plant's immune system protects the plant from harmful pathogens. If the system overreacts to pathogens, it can stunt plant growth and reduce seed production. view more (2009-05-28)
Why do insects like to eat some plants more than others?
In a study appearing in the forthcoming issue of The American Naturalist, Tom E. X. Miller, Andrew J. Tyre, and Svata M. Louda (all of the University of Nebraska, Lincoln) examined herbivore dynamics, specifically why plants aren't all eaten at the same rate. view more (2006-11-14)
Influenza: Insights into cell specificity of human vs. avian viruses
Researchers have identified which sites and cell types within the respiratory tract are targeted by human versus avian influenza viruses, providing valuable insights into the pathogenesis of these divergent diseases. view more (2007-10-10)
Promising antimicrobial attacks virus, stimulates immune system
A promising antimicrobial agent already known to kill bacteria can also kill viruses and stimulate the innate immune system, according to researchers at National Jewish Health. view more (2009-06-04)
Jefferson researchers' discovery may change thinking on how viruses invade the brain
A molecule thought crucial to ferrying the deadly rabies virus into the brain, where it eventually kills, apparently isn't. view more (2007-04-20)
West Nile's North American spread described
The rapid spread of West Nile virus in North America over the past decade is likely to have long-lasting ecological consequences throughout the continent, according to an article in the November issue of BioScience. view more (2008-11-03)
Human immunodeficiency virus (HIV) treatment
Russian researchers have developed a medication capable of protecting against various human immunodeficiency virus (HIV) strains. Their effort has been supported by the International Scientific Technical Center. Intense search for efficacious human immunodeficiency virus treatment carried out by scientific laboratories worldwide has not yet... view more... (2004-01-30)
Malaria researchers identify new mosquito virus
Researchers at the Johns Hopkins Bloomberg School of Public Health's Malaria Research Institute have identified a previously unknown virus that is infectious to Anopheles gambiae-the mosquito primarily responsible for transmitting malaria. view more (2008-08-22)
Viral marker of human migration suspect
A benign virus previously used as a marker in tracing human migration may be unreliable. view more (2006-10-25)
