News‘Raman barcodes’ can distinguish 20 SARS-CoV-2 variants
Viruses may carry a molecular ‘barcode’ hidden not just in their genetic sequence, but in the way their RNA folds and vibrates. Researchers have used Raman spectroscopy to distinguish 20 SARS-CoV-2 variants and subvariants, pointing towards a potentially faster way to screen emerging viral strains.

NewsScientists ‘crank up’ cells’ natural defence against viruses
Researchers have found a way to amplify one of the body’s natural antiviral defence pathways, making cells significantly more resistant to infection. By boosting signalling through the protein ISG15, the approach could lead to host-directed treatments that remain effective even as viruses mutate.

NewsResearch to uncover hidden life cycle of bacteriophages
Some bacteriophages can quietly replicate inside bacteria for generations without killing their hosts, making these infections difficult to detect with standard methods. A new research project will investigate this hidden life cycle and explore whether understanding it could help scientists engineer more effective phage therapies against drug-resistant infections.

NewsAdvanced air purification fails to reduce surgical infections
Cleaner operating-room air may not be enough to prevent surgical infections. In a study of more than 110,000 procedures, advanced air-purification systems did not reduce infections, complications or deaths, suggesting hospitals may gain more by targeting direct contamination of surgical wounds.

NewsCranberry juice may be a boon for oral hygiene
Pure cranberry juice may do more than add a tart kick to the holiday table. In a small human study, it slowed dental plaque growth and reduced acid production, suggesting the fruit’s natural compounds could help protect tooth enamel.

NewsLike humans, some primates become cautious of germs in the wake of a viral outbreak
Researchers found that macaque monkeys who had lived through a deadly disease outbreak became significantly more cautious about food that appeared contaminated, even though they did not know how the disease had spread. The findings suggest that pathogen-avoidance behavior can be shaped by experience, offering clues about the evolutionary roots of disgust.
