Antibiotics are no longer able to treat infections as effectively as they once did because many pathogens have developed ...

Viruses are everywhere in wastewater treatment plants, quietly interacting with bacteria as sewage is cleaned and reused.

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
