Viruses are typically described as tiny, perfectly geometric shells that pack genetic material with mathematical precision, ...

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 ...

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 ...

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 ...

Washington State University researchers are using AI and simulations to pinpoint a single molecular interaction that blocks ...

Identifying viral vs. bacterial sinusitis Although the vast majority of sinus infections are caused by viruses, IDSA recommends prescribing antibiotics for acute bacterial rhinosinusitis. Although the ...

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 ...

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 ...

In 2020, as scientists around the world were racing to understand COVID-19, Prof. Roy Bar-Ziv and his team at the Weizmann ...

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 ...
