To see how microgravity changes certain microbes, researchers sent bacteria-infecting viruses called bacteriophages to the ...

When a virus infects a bacterial cell, the viral genome is the first component to be fully injected into the cell, making it an ideal immune target. A bacterial enzyme anchored to the membrane ...

The virus is the human polyomavirus 2, commonly called either the JC virus or John Cunningham virus, named after the poor ...

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 ...

Antibiotic resistance is a global health challenge that could overtake cancer mortality within a few decades. In a new study, researchers at Umeå University, Sweden, show that the emergence of ...

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 ...

Researchers used a virus to treat patients with an antibiotic-resistant bacterial infection and found good clinical outcomes in 86.6 percent of patients. The study, published Aug. 9 in Cell, treated ...

The gut bacterium Bacteroides fragilis has long presented researchers with a paradox. It has been associated with colorectal cancer, yet it also lives quite happily in most healthy people. A study by ...

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 — ...
