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.

NewsMarine natural product derivative offers new therapeutic strategy to inhibit enterovirus A71 replication
Researchers revealed that the inhibition of enterovirus A71 (EV-A71) replication can be achieved by targeting the human coatomer subunit zeta-1 (COPZ1) using a marine natural product derivative known as MPA-CF3.

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.

NewsMicrorobot-packed pill shows promise for treating inflammatory bowel disease in mice
Engineers at the University of California San Diego have developed a pill that releases microscopic robots, or microrobots, into the colon to treat inflammatory bowel disease (IBD). The experimental treatment, given orally, has shown success in mice.

NewsShould you eat more dietary fiber? Depends on your gut microbes
Nutritionists generally advise everyone to eat more dietary fiber, but a new study suggests that its effects on health can vary from person to person. The findings indicate that recommendations should be tailored to each individual’s gut microbiome.
