NewsNew flu strain underscores urgent need for vigilance, vaccination, and investment in virus science
Virologists have issued a statement on the emergence of a new influenza A (H3N2) variant known as H3N2 subclade K that is spreading rapidly and may contribute to a more intense flu season worldwide. Public health agencies have reported sharp week-over-week increases in cases driven by this subclade.

NewsNatural, non-engineered bacterium selectively targets colorectal cancer
Scientists have demonstrated that the marine bacterium Photobacterium angustum exhibits potent antitumor effects against colorectal cancer. The natural bacterium requires no genetic modification yet selectively accumulates in tumor tissues with minimal impact on healthy organs.

NewsTeam discovers cyanobacteria activate different genes by day and by night
By analyzing gene expression in the cyanobacterium Nostoc punctiforme, scientists discovered that during daylight, the cells focus on metabolism. But under cover of darkness, they turn to the control of genome repair and activate various genetic elements.

NewsNew research confirms HPV vaccination prevents cervical cancer
Two new Cochrane reviews show strong and consistent evidence that HPV vaccines are effective in preventing cervical cancer and pre-cancerous changes, especially when given to young people before they are exposed to the virus.

NewsToxic gut bacteria may drive ulcerative colitis by killing protective immune cells
A toxin-secreting gut bacterium may fuel ulcerative colitis by killing protective immune cells that maintain intestinal homeostasis, according to a new study. The findings suggest potential for new treatment strategies.

NewsRebalancing lung repair with immune damage is key to surviving severe influenza
Recovery from deadly influenza infection may hinge on helping the lungs heal in addition to stopping the virus, according to a new study in mice, which shows that pairing modest antiviral therapies with immune modulation can restore damaged tissues and lung function, even after severe infection has taken hold.

NewsHear us out: scientists say garlic shows promise as a mouthwash alternative
Garlic extract demonstrates antimicrobial efficacy comparable to other widely used antiseptics and disinfectants, such as chlorhexidine, according to scientists. While garlic-based mouthwash may cause more discomfort than chlorhexidine, it offers longer-lasting residual effects.

NewsMicrobial nano-selenium breakthrough boosts tea quality and safety
Scientists developing selenium-enriched tea have identified a powerful selenium-reducing bacterium, Raoultella ornithinolytica S-1, capable of converting inorganic selenium into selenium nanoparticles (SeNPs) while simultaneously promoting plant growth.

NewsScientists reveal molecular cause behind “stuck” beer fermentation
Premature yeast flocculation (PYF) is a persistent issue in beer brewing, where yeast settles too early during fermentation. New research identifies multiple differential metabolites and confirmed galangin as a key factor that promotes early yeast aggregation.

NewsNew study finds higher levels of antimicrobial resistance (AMR) in surface water during winter
A new study has found that the levels of antimicrobial resistance (AMR) present in surface water increase during winter. Flooding, sewer overflows and agricultural run-off all contribute to a cocktail of pollutants that can increase AMR genes in surface water, potentially turning regular bugs into ‘superbugs’.

NewsThe road ahead: why conserving the invisible 99% of life is fundamental to planetary health
A new paper outlines how scientists came together to put together the first microbial conservation roadmap under the leadership of Applied Microbiology International President, Professor Jack Gilbert.

NewsLivestock manure linked to the rapid spread of hidden antibiotic resistance threats in farmland soils
Scientists have uncovered how even “low-risk” organic fertilizers like dried poultry manure can inadvertently drive a dramatic surge in dangerous antibiotic resistance genes, once released into vegetable plots used for food crops.

NewsScientists use computer model to improve hospitals’ ability to limit spread of drug-resistant infections
The computer model improves on traditional methods like contact tracing by inferring asymptomatic carriers in the spread of antibiotic-resistant infections.

NewsDrinking water people believe to be safe and clean often contain potentially dangerous bacteria
A study in Guatemala found the sources of drinking water people believe to be safe and clean often contain potentially dangerous bacteria. Bottled water sold in large refillable jugs was the most frequently contaminated with coliform bacteria – an indicator of fecal contamination.

NewsWorld’s largest metabolomic study completed, paving way for predictive medicine
UK Biobank has today released the final set of data on nearly 250 metabolites in half a million volunteers. This completes the world’s largest ever metabolomic study, which will help drive treatment strategies for neurological conditions, heart disease and cancer.

NewsSmart toilet designs in Cambodia held promise, but a key piece was missing
A smart toilet design introduced in rural Cambodia was supposed to change lives—keeping families safe and protecting the environment. However, while households reported that they liked the new system, a crucial piece was missing: using it correctly.

NewsStudy unveils structure, identification and characterization of the RibD-enolase complex in Francisella
A study aiming to identify anti-tularemia drug targets determined the atomic structure and identified its components of the native RibD-enolase protein complex in Francisella novicida.

NewsImpact of pasteurization on dairy calves’ gut microbiota: A study of milk feeding and early microbial colonization
A new study highlights the impact of pasteurization on microbial diversity in dairy calves, underlining the importance of balancing pathogen safety and microbial health. It suggests that while pasteurization prevents pathogen transmission, it also reduces beneficial microbial transfer.
