Researchers at the University of Massachusetts Amherst have designed non-toxic Salmonella bacteria to deliver viruses that ...

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 ...

Cancer research has long looked at bacteria and viruses as separate tools for therapy. Now, researchers are showing that the two can actually work better together. A team of scientists has built a new ...

A newly discovered virus hiding inside common gut bacteria may be linked to colorectal cancer, according to new research. Scientists in Denmark found that colorectal cancer patients were about twice ...

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 ...

As antibiotic-resistant infections rise and are projected to cause up to 10 million deaths per year by 2050, scientists are looking to bacteriophages, viruses that infect bacteria, as an alternative.

Pseudomonas bacteria infected by different mutations of a jumbo phage. The dot in the middle is the shield created by the phage to protect its DNA after it has infected the bacterial cell. Image by ...

Scientists investigating how influenza viruses replicate within cells "accidentally" discovered that different flu viruses ...

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 — ...

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 ...
