Scientists Win Race To Find Structure Of Rare Nematode Virus
2014-08-21 03:46:27

Rice University Rice University scientists have won a race to find the crystal structure of the first virus known to infect the most abundant animal on Earth. The Rice labs of structural biologist Yizhi Jane Tao and geneticist Weiwei Zhong, with help from researchers at Baylor College of Medicine and Washington University, analyzed the Orsay virus that naturally infects a certain type of nematode, the worms that make up 80 percent of the living animal population. The research...

University Of Arizona Scientists' Fishing Expedition Reveals Viral Diversity In The Sea
2014-07-21 03:46:48

University of Arizona A fishing expedition of microscopic proportions led by University of Arizona ecologists revealed that the lines between virus types in nature are less blurred than previously thought. Using lab-cultured bacteria as "bait," a team of scientists led by Matthew Sullivan has sequenced complete and partial genomes of about 10 million viruses from an ocean water sample in a single experiment. The study, published online on July 14 by the journal Nature, revealed that...

University of Utah University of Utah study shows last-minute role of protein named ALIX University of Utah researchers devised a way to watch newly forming AIDS virus particles emerging or "budding" from infected human cells without interfering with the process. The method shows a protein named ALIX gets involved during the final stages of virus replication, not earlier, as was believed previously. "We watch one cell at a time" and use a digital camera and special microscope to make...

University of Montreal scientists discover molecular details of kissing disease virus attacks University of Montreal researchers have discovered how a component of the Epstein Barr (EBV) virus takes over our cells gene regulating machinery, allowing the virus to replicate itself. The EBV virus causes a variety of diseases such as Hodgkin's lymphoma and Burkitt's lymphoma, with the most prevalent disease being infectious mononucleosis commonly known as "kissing disease" because of its mode...

Berkeley Researchers Show Expanded Role for Guide RNA in Cas9 Interactions with DNA The potential is there for bacteria and other microbes to be genetically engineered to perform a cornucopia of valuable goods and services, from the production of safer, more effective medicines and clean, green, sustainable fuels, to the clean-up and restoration of our air, water and land. Cells from eukaryotic organisms can also be modified for research or to fight disease. To achieve these and other...

Reducing viruses' glucose supply weakens the microbes' ability to infect mammalian cells in lab cultures Reducing glucose metabolism dials down influenza viral infection in laboratory cell cultures, providing an entirely new approach for combating seasonal flu, according to research that will be presented on Sunday, Dec. 15, at the American Society for Cell Biology (ASCB) annual meeting in New Orleans. While annual flu shots are based on the U.S. Centers for Disease Control (CDC)'s...

Researchers at Lund University in Sweden have for the first time managed to measure the internal pressure that enables the herpes virus to infect cells in the human body. The discovery paves the way for the development of new medicines to combat viral infections. The results indicate good chances to stop herpes infections in the future. A virus comprises a thin shell of protein, within which are its genes. A long-standing theory has been that a virus has high internal pressure because it...

The virus that causes those painful lip blisters known as cold sores has an internal pressure eight times higher than a car tire, and uses it to literally blast its infectious DNA into human cells, scientists are reporting in a new study. Discovery of the pressure-driven infection mechanism — the first in a human virus — opens the door to new treatments for viral infections, they add in a study in the Journal of the American Chemical Society. Alex...

Glimpse Into Untapped Biodiversity Offered By Newly Discovered Marine Viruses
2013-07-25 09:17:40

University of Arizona Studying bacteria from the Baltic Sea, University of Arizona researchers have discovered an entire array of previously unknown viruses that barely resemble any of the known bacteria-infecting viruses Researchers of the University of Arizona's Tucson Marine Phage Lab have discovered a dozen new types of unknown viruses that infect different strains of marine bacteria. Bacteriophages -- viruses that prey on bacteria -- are less familiar to most people than their...

Largest Virus Ever Discovered
2013-07-19 11:40:30

Brett Smith for redOrbit.com - Your Universe Online Once thought to be tiny and containing only a handful of genes, viruses have been redefined over the past decade by the discoveries of specimens the size of bacteria that contain 1,000 genes or more. According to a newly published report in the journal Science, French researchers have discovered a virus 1,000 times larger than the flu virus and which has almost 2,600 genes - the biggest virus known to date....

A virus is a small infectious agent that replicates inside the living cells of organisms. It is a small infectious agent that can replicate only inside the living cells of organisms. Most are too small to be seen by anything but a microscope and they infect all organisms from animals to plants to bacteria. The first one discovered was the tobacco virus in 1898. Since then around 5,000 viruses have been described in detail although there are millions of different types. They are found in...
