Researchers develop new test that detects all viruses that infect people and animals

There are some 320,000 unique mammalian viruses, according to estimates by virologists, and likely exponentially more existing on the planet today. Determining an accurate number would require billions more dollars and a great deal more manpower than is currently given to the study of viruses. Though a handful of viruses live in and on our bodies at all times—known as the virome—not all of them make us ill; just as often, they lie dormant. Many virus functions remain mysterious to scientists, such as how they enter a cell or replicate, though existing test advances, like the VirScan blood test, can tell you any infection you’ve ever had.

Anti-inflammatory ‘smart drug’ activates only in high-inflammation areas

Researchers at Ben-Gurion University of the Negev (BGU) in Israel and the University of Colorado have developed a dynamic anti-inflammatory “smart” drug that can target specific sites in the body and could enhance the body’s natural ability to fight infection while reducing side effects.

Researchers develop artificial spleen that cleans up blood infections

The ‘biospleen’ uses protein-equipped nanobeads and a magnet to cleanse blood of pathogens.

Researchers at the Wyss Institute for Biologically Inspired Engineering have developed a high-tech method to rid the body of infections — even those caused by unknown pathogens. A device inspired by the spleen can quickly clean blood of everything from Escherichia coli to Ebola, researchers report on 14 September in Nature Medicine.

Scientists develop GM chickens that do not spread bird flu.

British scientists have developed genetically modified (GM) chickens that cannot transmit bird flu infections — a step that in future could reduce the risk of avian flu spreading and causing deadly epidemics in humans.
