"It has been a paradox that we repeatedly find the same bacterium in connection with colorectal cancer, while at the same time it is a completely normal part of the gut in healthy people," says ...

An oncologist explains the findings.

Bacteria and viruses are often lumped together as germs, and they share many characteristics. They’re invisible to the human eye. They’re everywhere. And both can make us sick. Bacteria and viruses ...

The research, published in Science Advances, brought together scientists from Otago and the Okinawa Institute of Science and Technology. The team closely examined the molecular structure of Bas63, a ...

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 ...

Peering through his microscope in 1910, Franco-Canadian microbiologist Félix d'Hérelle noticed some "clear spots" in his bacterial cultures, an anomaly that turned out to be viruses preying on the ...

Scientists have discovered a new type of immune defense in E. coli bacteria that turns viral infection machinery against the virus itself. Named after the Chinese military strategist Kongming—who ...

Researchers at Columbia Engineering have built a cancer therapy that makes bacteria and viruses work as a team. In a study published today in Nature Biomedical Engineering, the Synthetic Biological ...

That shared tactic exposes a vulnerable point in one of bacteria’s most essential systems and reframes where new antibiotics ...

A vaccine usually trains your immune system to recognize one target. Here, the target is basically “anything that doesn’t belong in the lungs.

Biochemists at Caltech have identified how viruses have converged on a method for killing bacteria. The researchers have homed in on an underexplored small transporter called MurJ that is a vital part ...

As vital as vaccines are, they can be frustratingly selective about their targets. Scientists from institutions across the US ...
