Direct transfer of plant genes from chloroplasts into the cell nucleus
Chloroplasts, the plant cell's green solar power generators, were once living beings in their own right. This changed about one billion years ago, when they were swallowed up but not digested by larger cells. ...

To drive infections, a hijacking virus mimics a cell's signaling system
New biological research reveals how an invading virus hijacks a cell's workings by imitating a signaling marker to defeat the body's defenses. By manipulating cell signals, the virus destroys a defensive protein designed ...

Frontal attack or stealth? How subverting the immune system shapes the arms race between bacteria and hosts
Why is it that Mycobacterium tuberculosis can cause tuberculosis with as little as 10 cells, whereas Vibrio cholerae requires the host to ingest up to tens of millions of cells to cause cholera? This is the ...

Host (biology)
In biology, a host is an organism that harbors a virus or parasite, or a mutual or commensal symbiont, typically providing nourishment and shelter. In botany, a host plant is one that supplies food resources and substrate for certain insects or other fauna. Examples of such interactions include a cell being host to a virus, a legume plant hosting helpful nitrogen-fixing bacteria, and animals as hosts to parasitic worms, e.g. nematodes.
