NewsGut microbiome affects alcohol preference by influencing brain’s reward system
A new study shows how an overgrowth of Candida albicans - overly abundant in people with alcohol use disorder - increases levels of inflammatory molecules that can cross the blood-brain barrier and affect the desire for alcohol.

NewsAfrican wildlife poop sheds light on what shapes the gut ecosystem
A study of elephants, giraffes and other wildlife in Namibia’s Etosha National Park underscores the ways in which the environment, biological sex, and anatomical distinctions can drive variation in the gut microbiomes across plant-eating species.

NewsResearch alert: Bacterial chatter slows wound healing
Researchers have discovered a previously unrecognized mechanism by which Staphylococcus aureus delays wound healing. The study finds that quorum sensing is a key driver of delayed healing in wounds infected by S. aureus.

NewsBiologist links stable gut bacteria to healthy childhood growth
New research reveals that the stability of gut bacteria in early life plays a critical role in whether children thrive or struggle with undernutrition – a global health challenge affecting millions.
-
NewsIn chromosome of key biotech bacterium, different setups bring different strengths
New research has found that the effectiveness of biotech bacterium Agrobacterium tumefaciens’ virulence varies, depending on how its chromosome is arranged.

NewsFriendly soil microbes can boost protein in staple crops
Researchers investigated how a bacterium naturally found in the soil that is beneficial to human health can enhance the levels of the amino acid and antioxidant ergothioneine in spring wheat.

NewsBiochar shows big promise for climate-friendly soil management
Turning agricultural and organic waste into biochar could help store more carbon in the soil and slow climate change, according to a new study. Recent findings show that biochar improves soil health, boosts microbial diversity, and captures carbon.

NewsResearchers discover method to combat antibiotic treatment failure
Researchers explored ways to alter our own immune cells to help antibiotics work more effectively. They identified a small molecule that alters the body’s immune cells, forcing them to ’wake up’ dormant bacteria and make them more vulnerable to antibiotic treatment.

NewsResearchers partner on $28M initiative to build a precision phage platform for promoting public health
Researchers have embarked on a five-year initiative that aims to harness the natural predators of bacteria – known as phages – as precision tools to shape the human microbiome and promote health.

NewsLake Tahoe algae experiment suggests seasonal shifts ahead
As the climate warms and nutrient inputs shift, algal communities in cool, clear mountain lakeswill likely experience seasonal changes, according to a new study. The effects of climate warming were especially pronounced in the colder months.

NewsWhen faucets rest: hidden microbial risks emerge in hours
Stagnant water in building plumbing systems is a well-known driver of microbial growth and contamination, including L. pneumophila. A new study highlights a short “microbial safety window” of 2–4 hours, after which risks increase significantly.

NewsTwo-dose recombinant shingles vaccine is effective even accounting for prior receipt of live shingles vaccine
A target trial emulation was conducted to assess the effectiveness of recombinant zoster vaccine (RZV) accounting for prior receipt of live zoster vaccine (ZVL) and immunocompetence. The results suggest individuals vaccinated with ZVL should be revaccinated with two doses of RZV.

NewsSped-up evolution may help bacteria take hold in gut microbiome
A genetic mechanism inserts mutations into key DNA hotspots that enable bacteria to adapt to new environments, a new study finds.
-
NewsResearchers map correlations between gene variants and proteomes
Scientists have discovered a way to predict the effects of numerous mutations in yeast - a valuable tool for better understanding molecular mechanisms. Key to this discovery was a detailed analysis of the proteome – the collection of all proteins inside a cell.

NewsStudy finds HEPA purifiers alone may not be enough to reduce viral exposure in schools
In a secondary analysis of a study of 200 classrooms, researchers found respiratory viral exposures were still high in those with HEPA purifiers, suggesting additional interventions are needed.
