Researchers studying strains of a lethal canine virus and a related human virus believe that the canine virus will open doors to understanding how viruses jump from one species to another.

Newswise features an advance online paper published in the April 2006 issue of the Journal of Virology, in which Laura Shackelton, an HHMI predoctoral fellow at the University of Oxford in England, examined the surprisingly rapid evolution of the B19 erythrovirus, a ubiquitous human parvovirus

New research shows drinking Concord grape juice inhibits the formation of breast tumors in laboratory rats while also reducing the amount of DNA damage to mammary glands.

The study published in the latest issue of Cancer Letters is giving new reason to drinking the sweet dark juice

Researchers have discovered that the so-called flesh-eating "Strep" bacteria uses a specific enzyme to break free of the body's immune system. This new finding could potentially lead to new treatments for serious infections in human patients.

The research, published in the Current Biology journal, focuses on the major human pathogen group A Streptococcus. Strep is responsible for a wide range of diseases - from simple throat and skin infections to life-threatening conditions such as necrotizing fasciitis ("flesh-eating disease") and toxic shock syndrome

Scientists announce a newly produced vaccine against the H5N1 strain of bird flu that has protected mice, using a genetic engineering technique that can be easily scaled up for stockpiling the drug to prepare for a pandemic.

In a report published Thursday by a British medical journal The Lancet, researchers say the experimental vaccine uses a common cold virus or adenovirus engineered with bird flu DNA, to stimulate the body's defenses

Researchers have shown through DNA examination that dancers show consistent differences in two key genes from the general population.

Prof. Richard P. Ebstein doesn't find the results surprising, noting that other studies of musicians and athletes also have shown genetic differences
