NewsDegradation of cell wall key in the spread of resistance
A new study shows how an enzyme breaks down the bacteria’s protective outer layer, the cell wall, and thus facilitates the transfer of genes for resistance to antibiotics.

NewsLong-standing marine mystery solved: How algae get nitrogen to grow
In a new study, scientists have shed light on an unexpected partnership: a marine diatom and a bacterium that can account for a large share of nitrogen fixation in vast regions of the ocean.

NewsResearchers deploy E coli to selectively target tumor cells
Scientists explore how an engineered bacterium limits tumor growth and maximizes targeted anticancer drug delivery.

NewsSurvey finds many have misconceptions about sexually transmitted infection risk
Sexually transmitted infections (STIs) are on the rise in the U.S., including an 80% increase in syphilis over a five-year period, but a new survey finds many Americans have misconceptions on how STIs are spread and who should be treated.

NewsResearchers unlock gateway to open up more bacterial species for research
Researchers have introduced a novel approach that can make many more bacteria amenable to genetic engineering. Their method, called IMPRINT, uses cell-free systems to enhance DNA transformation across various bacterial strains.

NewsSpecific bacteria in your gut are involved in compulsive eating and obesity
Researchers have identified specific bacteria in the gut that are associated with both mice and humans developing an addiction to food that can lead to obesity. They have also identified bacteria that play a beneficial role in preventing food addiction.

NewsDiagnostic stewardship approach to C. diff reduces unnecessary testing
Revised rules for when Clostridioides difficile tests could be ordered helped to reduce inappropriate testing by 20%, which in turn can help rein in the overtreatment of patients.

NewsScientists discover genetic ‘off switch’ in legume plants that limits biological ability to source nutrients
The discovery of a new genetic regulator in legumes could be key to understanding how to increase the crop’s capacity to convert nitrogen from the air and improve soil quality.
