Certain viruses attack bacteria and can sometimes clear antibiotic-resistant infections. Researchers said they had tailored a ...

“This is one of the most common forms of bacterial immunity, so when we finally figured it out, it was a total eureka moment, ...

Some viruses that infect bacteria carry an enzyme that gives them away. When that enzyme, a protease, cuts a particular ...

Humans throughout history have invented a variety of ways to fight back against troublesome bacteria. But bacteria live in a ...

Researchers have uncovered a new way bacteria detect viral attacks: a virus-produced enzyme cuts a bacterial sensor protein, triggering a self-destructing immune response. The discovery could lead to ...

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 ...

When a virus enters a cell, its top priority is to replicate its genome rapidly, creating new viruses to infect elsewhere. The host has the opposite priority: to destroy the virus, ideally before it ...

Bacteriophages, or viruses that infect bacteria, have a fiendishly simple purpose in life: attach to a bacterial cell, inject ...

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 ...

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 ...

A new study puts some old folk wisdom to "feed a cold and starve a fever" to the test. In mouse models of disease, Yale researchers looked at the effects of providing nutrients during infection and ...
