Biologists discover how viruses hijack cell's machinery

Biologists at UC San Diego have documented for the first time how very large viruses reprogram the cellular machinery of bacteria during infection to more closely resemble an animal or human cell—a process that allows these ...

When viruses infect bacteria

(PhysOrg.com) -- Viruses are the most abundant parasites on Earth. Well known viruses, such as the flu virus, attack human hosts, while viruses such as the tobacco mosaic virus infect plant hosts.

Detecting lethal diseases with rust and sand

The next big thing in medical diagnostics could be minutes particles of rust, iron oxide, coated with the material from which sand is formed, silicon dioxide. These magnetic nanoparticles, a mere 29 to 230 nanometers across, ...

Knockouts in human cells point to pathogenic targets

(PhysOrg.com) -- Whitehead researchers have developed a new approach for genetics in human cells and used this technique to identify specific genes and proteins required for pathogens.
