After nearly 40 years of research on how Listeria bacteria manipulate our cells and battle our immune system to cause listeriosis, Daniel Portnoy and his colleagues have discovered a way to turn the ...

Viruses attack nearly every living organism on Earth. To do so, they rely on highly specialized proteins that recognize and ...

Common gut bacteria use protein delivery systems to interact directly with human cells, reshaping how scientists view the ...

Harvard immunologist Dennis Kasper and his colleagues have found that tiny changes in gut bacteria can flip the immune system from calm to inflamed, even when the microbes look harmless. Their work, ...

A new study finds that a trait helping a marine bacterium survive and flourish today may ultimately become its Achilles Heel as ocean conditions continue to shift.

Scientists at LSU have patented a novel way to kill cancer cells using staph bacteria, sometimes called the “superbug.” ...

Immune cells that eat bacteria in the body don't stash them in specialized compartments as once thought, but turn them into critical nutrients that build proteins, create energy and keep the cells ...

A new study reveals how bacteria in the gut can help determine whether the amino acid asparagine from the diet will feed ...

Biologists have uncovered a new mode of communication inside cells that helps bacterial pathogens learn how to evade drugs.

In tight spaces that trap most microbes, one bacterium keeps moving by reconfiguring how it swims, revealing a new biological strategy.

The enzyme Na⁺-NQR is a sodium pump that drives the respiration of many marine and pathogenic bacteria. Using redox reactions ...
