Siberian Permafrost Reveals Ancient Giant Virus, Remains Infectious

Lawrence LeBlond for redOrbit.com - Your Universe Online Giant viruses may seem like the latest creation in a Hollywood B movie production, but the recent discovery of a larger-than-life virus buried in ice is definitely no science-fiction tale. A husband-and-wife team from Aix-Marseille University in France have discovered a monster virus that has been buried in Siberia’s permafrost for the past 30,000 years. Jean-Michel Claverie and Chantal Abergel, who led the discovery, have...

A virus discovered in the sea off the coast of Chile is the largest in the world, containing more than 1,000 genes, scientists reported on Monday. The DNA code of Megavirus chilensis is 6.5 percent bigger than the genome of the Mimivirus, the previous virus record-holder isolated in 2003. Viruses are typically much smaller than bacteria, and cannot reproduce on their own.  Rather, they require a host cell in which to replicate. However, M. chilensis is so large that it surpasses...

Two studies published in the February 3 issue of Nature demonstrate how the unique capabilities of the world's first hard X-ray free-electron laser"”the Linac Coherent Light Source, located at the Department of Energy's SLAC National Accelerator Laboratory"”could revolutionize the study of life.In one study, an international research team used the LCLS to demonstrate a shortcut for determining the 3-D structures of proteins. The laser's brilliant pulses of X-ray light pulled...

UBC researchers have identified the world's largest marine virus--an unusually complex 'mimi-like virus' that infects an ecologically important and widespread planktonic predator. Cafeteria roenbergensis virus has a genome larger than those found in some cellular organisms, and boasts genetic complexity that blurs the distinction between "non-living" and "living" entities. "Virus are classically thought of small, simple organisms in terms of the number of genes they carry," says UBC professor...

French scientists have identified a giant new virus dwelling inside an amoeba, and that it contains genetic material from other species. The so-called Marseillevirus is "a completely new viral form," said Didier Raoult, head of infectious and emerging tropical disease research at Aix-Marseille 2 University in France, during an interview with the AFP news agency. The genome of the 250 nanometer-diameter Marseillevirus includes a sophisticated set of genes that are "very different from the DNA...

The mimivirus is the largest virus known to scientists, about half of a micrometer (0.0005 millimeter) in diameter. It is more than 10 times larger than the virus that causes the common cold and "“ unlike other viruses "“ is large enough to be seen with a light microscope. In this week's issue of PLoS Biology, an international team of researchers have determined key structural features of the mimivirus, findings that could help scientists study how the simplest life forms evolved...

Using the Genome Sequencer System from 454 Life Sciences, a Roche company, French scientists have identified a small virus that can actually be parasitic to a larger one. The 50 nm virus, named Sputnik, is associated with a new strain of the giant Acanthamoeba polyphaga mimivirus (APMV) and is believed to represent a currently unknown family of viruses. The study, entitled "The virophage as a unique parasite of the giant mimivirus," appeared in the September 4th issue of Nature (1). The...

The African Swine Fever virus, ASFV, is a double-stranded DNA virus that replicates in the cytoplasm of infected cells. It can affect most pigs, wild and domesticated, as well as soft ticks. It is the only virus with a DNA genome that is transmitted by arthropods. The virus causes a lethal hemorrhagic disease in domestic pigs which sometimes leads to death in as little as a week. In every other species the virus causes no discernible disease. The virus is endemic to Sub-Saharan Africa...
