A common virus that causes meningitis and heart inflammation takes a "back door" approach to evade natural barriers, then exploits biological signals to infect human cells.   view more (2006-01-13)

New UNC experiments show very weak chlorine solutions can kill noroviruses
Chlorine solutions much weaker than previously believed can still be used to kill more than 99 percent of noroviruses, the chief cause of outbreaks of gastrointestinal illness around the world, a new University of North Carolina at Chapel Hill study concludes.   view more (2005-12-20)

Slowdown in tropical Pacific flow pinned on climate change
The vast loop of winds that drives climate and ocean behavior across the tropical Pacific has weakened by 3.5% since the mid-1800s, and it may weaken another 10% by 2100.   view more (2006-05-04)

Learning How SARS Spikes Its Quarry
Researchers have determined the first detailed molecular images of a piece of the spike-shaped protein that the SARS virus uses to grab host cells and initiate the first stages of infection.   view more (2005-09-16)

How HIV 'exhausts' killer T cells
American and South African scientists working at the epicenter of the AIDS epidemic in South Africa have discovered how the human immunodeficiency virus (HIV) "exhausts" killer T cells that would otherwise attack the virus.   view more (2006-08-21)

OHSU researchers demonstrate how white blood cells cannibalize virus-infected cells
Researchers at the Vaccine and Gene Therapy Institute (VGTI) at Oregon Health & Science University have demonstrated how certain white blood cells literally eat virus-infected cells while fighting disease at the microscopic level.   view more (2006-10-03)

New human retrovirus originated in mice
Howard Hughes Medical Institute researchers and their colleagues have discovered a new retrovirus in humans that is closely related to a cancer-causing virus found in mice.   view more (2006-03-31)

Antiviral drugs may help relieve nerve pain related to shingles
A small trial suggests that treatment with intravenous and oral antiviral medications may reduce the nerve pain that occurs following shingles.   view more (2006-05-09)

Test predicts risk of liver scarring after transplant, study shows
An estimated 20 percent of people with chronic hepatitis C who receive a liver transplant will develop advanced cirrhosis, scarring of the new organ severe enough to impair its ability to function normally within five years of transplantation.   view more (2005-10-06)

Viruses can jump between primates and humans, researchers warn
Viruses that jump the species barrier between monkeys and humans can harm both people and animals, and we should take steps to reduce the risk of virus transmission.   view more (2006-08-24)

Experimental vaccine protects nonhuman primates from Lassa fever
A team of U.S. and Canadian scientists has developed a vaccine against Lassa fever that fully protects nonhuman primates from experimental infection with lethal doses of Lassa virus.   view more (2005-06-28)

Researchers develop new testing methods for potential monkeypox or smallpox outbreak
Researchers at the Vaccine and Gene Therapy Institute (VGTI) at Oregon Health & Science University have developed new diagnostic methods to better detect future monkeypox or smallpox outbreaks.   view more (2005-08-09)

Deaths from rodent virus raise need for tracking system
After the deaths of seven people from a virus transmitted through organ donation in the past two years, authorities are recommending that a tracking system be put in place to monitor patients following transplantation, and until then, physicians should be more vigilant in looking for signs of... view more (2006-05-25)

New protein target may advance design of HIV and cancer drugs
Using small molecules containing platinum, Virginia Commonwealth University Massey Cancer Center researchers have created a process to inhibit a class of proteins important in HIV and cancer.   view more (2006-05-31)

Mosquito spray increases toxicity of pyrethroids in creek, study finds
A relatively benign compound contained in a widely used group of insecticides can mix with and increase the toxicity of existing pesticides in the environment   view more (2006-07-28)

Researchers find 'secret weapon' used by SARS virus
In 2003, the highly contagious and often-deadly mystery disease now called SARS emerged explosively out of Southern China. It eventually killed an estimated 916 people in Asia, Europe, and North and South America-nearly one in ten of those it infected.   view more (2006-08-08)

Clue found to Epstein-Barr virus' ability to form and sustain tumors
Researchers at the University of Wisconsin School of Medicine and Public Health (SMPH) have found a viral target that opens the door for the development of drugs to destroy tumors caused by Epstein-Barr virus (EBV).   view more (2006-09-06)

Shift in feeding behavior of mosquitoes sheds light on West Nile virus outbreaks
Since its introduction to the United States in 1999, West Nile virus has become the major vector-borne disease in the U.S., with 770 reported deaths, 20,000 reported illnesses, and perhaps around a million people infected.   view more (2006-02-28)

A new step towards an AIDS vaccine
Progressive disease after HIV infection is inversely correlated with the presence of plasmacytoid dendritic cells (pDCs), a subset of the dendritic cell family and the major producers of type 1 interferon in the body.   view more (2005-10-14)

Wide-spread use of intranasal flu vaccine does not show unexpected serious risks
Approximately 2.5 million people received the intranasal influenza vaccine the last 2 flu seasons, and a new study did not identify unexpected serious risks associated with use of this vaccine.   view more (2005-12-07)

Inhibition of iron-metabolizing enzyme reduces tumor growth
A report in the Journal of Biological Chemistry shows that inhibition of heme oxygenase-1, an enzyme involved in iron metabolism, reduces Kaposi sarcoma tumor growth.   view more (2006-04-21)

Montreal researchers make a major strategic breakthrough in controling the AIDS virus
A team of researchers from the Université de Montréal and the Centre hospitalier de l'Université de Montréal (CHUM) have announced an important breakthrough in fighting the human immunodeficiency virus (HIV).   view more (2006-08-22)

In a crisis, creating DNA vaccine could help save lives, slow spread of 'bird flu'
Researchers scrambling to combat a virulent form of bird flu that could mutate into a form easily spread among humans should consider developing vaccines based on DNA, according to British biochemical engineers.   view more (2005-10-20)

Researchers use mass spectrometry to detect norovirus particles
Scientists have used mass spectrometry for decades to determine the chemical composition of samples but rarely has it been used to identify viruses, and never in complex environmental samples.   view more (2006-04-07)

Study holds promise for new way to fight AIDS
For years researchers have been trying to understand how a few HIV-infected patients naturally defeat a virus that otherwise overwhelms the immune system.   view more (2006-11-02)
