    Astonishingly, a virus that exclusively attacks the cholera bacteria was caught having stolen the functional immune system of bacteria—and is even using it against its bacterial host. A study published this week in the journal Nature provides the first evidence that this type of virus, a bacteriophage (“phage” for short), can acquire a wholly functional and adaptive immune system, something that was thought to be a too complex task for the very basic and “dumb” virus. The phage used the stolen immune system to disable—and thus defeat—the cholera bacteria’s defense system against phages. Therefore, the phage can kill the cholera...

    Viral Batteries: A Case for Evolution? by Brian Thomas, M.S.* Researchers at MIT have invented a “greener” battery with the help of viruses. Three years ago, they engineered a virus that coats itself with material that serves as an anode, a structure within a battery that attracts positive ions. They have now engineered a virus (bacteriophage) that serves as a cathode, which indirectly links to the anode to help make the battery functional. The result is a battery with little impact on the environment. National Public Radio (NPR) ran a report on its Morning Edition that compared the development of...

    Associated Press A mix of bacteria-killing viruses can be safely sprayed on cold cuts, hot dogs and sausages to combat common microbes that kill hundreds of people a year, federal health officials said Friday in granting the first-ever approval of viruses as a food additive. The combination of six viruses is designed to be sprayed on ready-to-eat meat and poultry products, including sliced ham and turkey, said John Vazzana, president and chief executive officer of manufacturer Intralytix Inc. The special viruses called bacteriophages are meant to kill strains of the Listeria monocytogenes bacterium, the Food and Drug Administration said in...
