For millennia, humans and viruses have been locked in an evolutionary back-and-forth -- one changes to outsmart the other, prompting the second to change and outsmart the first. With retroviruses, which work by inserting themselves into their host's DNA, the evidence remains in our genes.

La Jolla Institute for Allergy & Immunology (LIAI) scientists have discovered one for the textbooks. Their finding, reported Friday in the scientific journal Immunity, illuminates a new, previously unknown mechanism in how the body fights a virus.

After studying chimpanzees in the wilds of Tanzania's Mahale Mountains National Park for the past year as part of a National Science Foundation (NSF) grant, Virginia Tech researcher Dr. Taranjit Kaur and her team have produced powerful scientific evidence that chimpanzees are becoming sick from viral infectious diseases they have likely contracted from humans.

Replacing one amino acid on the surface of a virus that shepherds corrective genes into cells could be the breakthrough scientists have needed to make gene therapy a more viable option for treating genetic diseases such as hemophilia, University of Florida researchers say.

IRI Separation Technologies (TSX.V:IRI) is the manufacturer of a remarkable new dietary supplement that enhances the human body’s natural immune system through direct supplementation of actual antibodies . The product will be available in the United States and Canada under the brand name “Muno Boost” and will be available as an over-the-counter dietary supplement in pharmacies and through direct marketing.

A deadly intestinal virus outbreak in China has claimed another life taking the death toll to 22, prompting the health ministry to order a nation-wide alert as the virus showed signs of spreading. The virus seem to effect mainly children.

Symantec Corp. (Nasdaq: SYMC) today announced it has earned an unprecedented 35th consecutive VB100 Award from Virus Bulletin. While many other security vendors failed the December 2007 tests, Symantec was one of only two vendors to receive a perfect detection score for all test sets, including “in the wild” malware, and today’s more complex threats such as file infectors, worms and bots, as well as DOS, macro and polymorphic viruses.

When a vaccine to prevent shingles was approved for use in 2006, the Food and Drug Administration recommended the vaccine for people age 60 and older who previously had chickenpox.

When the alert goes out that a virus has invaded the body, cells that have yet to be attacked prepare by "armoring" themselves for combat, attaching specific antiviral molecules to many of their own proteins to help resist the invader.

YEREVAN (Noyan Tapan)--According to the Armenian National Security Services, a computer virus program dubbed "Perfect Key Logger" has been discovered in a number of computers in Armenia. The source of the virus has been traced to Azerbaijani Special Foreign Services.

For the first time scientists have been able to film, in real-time, the nanoscale interaction of an enzyme and a DNA strand from an attacking virus. Researchers from the University of Cambridge have used a revolutionary Scanning Atomic Force Microscope in Japan to produce amazing footage of a protective enzyme unravelling the DNA of a virus trying to infect a bacterial host.

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).
