NewsHIV targeted with novel dual gene-editing approach
Gene-editing therapy aimed at two targets – HIV-1, the virus that causes AIDS, and CCR5, the co-receptor that helps the virus get into cells – can effectively eliminate HIV infection, new research shows.
-
NewsRare yeast pathogen causing neonatal outbreaks
Scientists studying the stubborn and dangerous rare yeast pathogen behind two outbreaks in a neonatal intensive care unit in Delhi, India, have found that while infected patients can be treated with antifungal medications, the yeast is remarkably resistant to the strong disinfectant bleach commonly used to sanitize hospital rooms.

NewsGut microbiome fluctuates through days and seasons
The balance of microbes in the human gut varies substantially from morning to night and even more by season, with profound fluctuations completely transforming the microbiome from summer to winter, a new study reveals.
-
NewsSensor controls how dormant bacteria reawaken
Researchers have discovered a new kind of cellular sensor that allows spores to detect the presence of nutrients in their environment and quickly spring back to life.

NewsStool transplants more effective than antibiotics for treating recurring, life-threatening gut infections
A new Cochrane Review has found that, compared with standard antibiotic treatment, stool transplantation can increase the number of people recovering from Clostridioides difficile infection from 40% to 77%.
-
NewsNew biologic effective against major infection in early tests
Researchers have shown in early tests that a bioengineered drug candidate can counter infection with Staphylococcus aureus – a bacterial species widely resistant to antibiotics and a major cause of death in hospitalized patients.
-
NewsInfectious SARS-CoV-2 isolated from hospital air samples
Scientists have succeeded in isolating infectious particles of the SARS-CoV-2 virus from air samples collected from hospital rooms of COVID-19 patients and kept frozen for more than a year, a new study shows.
