Scientists armed bacteria with cancer-killing viruses that infiltrate tumors, evade immunity, and attack from within.

Bacteria and viruses are the most common causes of disease, but they have some key differences. Here's what you need to know.

Jumbo phages belong to a group of viruses that attack bacteria. They inject their DNA and then reproduce by taking over the cell’s DNA-copying machinery. Eventually, a phage makes so many copies of ...

Long before humans became interested in killing bacteria, viruses were on the job. Viruses that attack bacteria, termed "phages" (short for bacteriophage), were first identified by their ability to ...

We share the world with vast numbers of microbes, including archaea, bacteria, and viruses. These microbes have numerous survival strategies. Some bacteria, for example, are able to enter dormant ...

Bacteria often go dormant to avoid being wiped out by antibiotics, which makes treatment difficult. Now scientists have discovered a virus that can attack these sleeping bugs, clearing out infections ...

One possible solution to the problem of antimicrobial resistant organisms is designing bacteriaphages, or simply phages, to ...

Viruses may get a bad rap, but some of them can be helpful to fight off bacterial infections. Scientists at ETH Zurich have demonstrated a new way to use them to diagnose which bacteria is causing a ...

A group of researchers has brought the idea of food as a medicine one step closer. They have identified certain common foodstuffs that alter our microbiome. Illustration of phage viruses attacking a ...

In the opening of HBO’s The Last of Us, a couple of scientists on a 1960s-era interview show debate the possibility of a fungus-driven pandemic destroying humanity. It not only sets the tone for the ...

As a general rule, most people want to avoid viruses, which are at the root of illnesses like colds, the flu, chickenpox and many a stomach bug. But what about a virus that doesn’t make people sick — ...
