Latest Viral evolution Stories
Radically different viruses share genes and are likely to share ancestry.
The discovery of a mummified Korean child with relatively preserved organs enabled an Israeli-South Korean scientific team to conduct a genetic analysis on a liver biopsy which revealed a unique hepatitis B virus (HBV) genotype C2 sequence common in Southeast Asia.
A study published in BioMed Central's Biology Direct journal reports the existence of a previously undetected group of viruses and, more importantly, a new type of viral genome that could have huge implications for theories of viral emergence and evolution.
Biologists from The University of Texas at Arlington have uncovered virus fragments from the same family of the modern Hepatitis B virus locked inside the genomes of songbirds such as the modern-day zebra finch.
In biology and genetics, the concept of epistasis is what gives rise to the whole being more (or less) than the sum of its parts.
The team observed viruses as they evolved over hundreds of generations to infect bacteria.
Research published in the journal Genetics suggests that mutagenic drugs designed to kill viruses may make them stronger.
U.S. medical scientists say they've created the most comprehensive mathematical analysis to date of the mechanisms that drive viral and bacterial evolution. The Rice University study is designed to help produce a designer drug that would force a killer virus to mutate itself out of existence.
It sounds like a science fiction movie: A killer contagion threatens the Earth, but scientists save the day with a designer drug that forces the virus to mutate itself out of existence.
