Microbiologists Patrick Moreira and Purificación López-García, together with virologists Arturo Ludmir and Lynn Enquist, are ...

Penn State scientists uncovered an ancient bacterial defense where dormant viral DNA helps bacteria fight new viral threats. The enzyme PinQ flips bacterial genes to create protective proteins that ...

While many viruses kill their hosts, not all viruses are harmful. In fact, some even benefit the cells they infect. For instance, temperate phages are viruses capable of replicating innocuously inside ...

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 — ...

As the number of antibiotic-resistant infections continues to rise, scientists are looking to bacteriophages (“phages”), viruses that infect bacteria, as an approach to tackling antibiotic resistance.

New study shows how bacteria adapted a virus-derived injection system to recognize and attach to many different types of ...

A new year might mean new viral threats. Old viruses are constantly evolving. A warming and increasingly populated planet puts humans in contact with more and different viruses. And increased mobility ...

Viral DNA that is usually dismissed when sequencing the human genome could help to uncover useful information about complex diseases.

The idea that a single-celled bacterium can defend itself against viruses in a similar way as the 1.8-trillion-cell human immune system is still “mind-blowing” for molecular biologist Joshua W. Modell ...
