How a retrovirus, like HIV, reproduces and assembles new viruses is different than previously thought, according to researchers.
The team studied a chicken virus called Rous sarcoma virus that causes cancer in chickens and is similar to HIV.
“The question is, how do retroviruses build new ... Read More
The best defense against a deadly superbug might be a virtual offense.
Duke University researchers are expanding upon a computer program they invented last year to predict how a rapidly mutating, infectious bacterium will evolve to evade the drugs used against it. Getting a glimpse into what ... Read More

Oregon State University engineers have applied new coatings on anodes of microbial electrochemical cells, which heightens their electricity production by 20 times, and is another step closer to producing electricity from sewage.
The graphite anodes were coated with palladium at one point in ... Read More
For years, human immunodeficiency virus (HIV) researchers have shied away from the whole notion of a cure, largely because evidence showed the virus can persist even under intensive treatment.
But now, they are -- tentatively -- expressing a renewed interest in the idea.
That interest is ... Read More
The illustration at left depicts a virion – the infectious particle that is designed for transmission of the nucleic acid genome among hosts or host cells. A virion is not the same as a virus. I define virus as a distinct biological entity with five distinct characteristics. Others believe that ... Read More
Mothers who drink milk containing 'friendly bacteria' (probiotics) while pregnant and breastfeeding may reduce their child's risk of developing eczema, reports a new study. And if their child does develop eczema, it may be less severe.

New species of bacteria have been discovered which can break down sodium oxalate impurities produced during the refining of bauxite into alumina.
Oxalate affects the quality of the final product. At present, refiners can either remove the oxalate and store it, which is expensive, or burn it o... Read More
A research team led by scientists at the Virginia Bioinformatics Institute (VBI) at Virginia Tech has discovered a fundamental entry mechanism that allows dangerous fungal microbes to infect plants and cause disease. The discovery paves the way for the development of new intervention strategies ... Read More
The number of Internet searches has recently been used by Google to estimate the influenza incidence in the United States.
