Billions of doses later: Global review confirms mRNA vaccines are safe, effective and full of promise
After billions of doses administered globally, a comprehensive University of British Columbia-led review has delivered a definitive verdict: mRNA vaccines are safe and highly effective against infectious diseases including COVID-19. The technology's potential reaches well beyond its pandemic debut, with researchers pointing to promising applications in influenza, RSV, cancer, and autoimmune conditions. The findings reinforce mRNA platforms as one of modern medicine's most consequential breakthroughs.

Treatment for alcohol use disorder can reverse harmful brain effects
Treatment for alcohol use disorder can undo more than behavioral patterns — it can repair the brain's chemistry. A new study in Neuropsychopharmacology found that chronic drinking disrupts how the brain metabolizes acetate, a byproduct of alcohol breakdown in the liver. Crucially, researchers confirmed these metabolic changes are reversible, strengthening the case for early and sustained treatment intervention.

Novel biomarker beats leading diagnostic blood test at predicting Alzheimer's progression
Researchers have identified circular RNAs in the blood as powerful predictors of Alzheimer's onset, with elevated levels nearly tripling a patient's risk of developing symptoms. Published in Nature Medicine, the study found these molecules outperform traditional Alzheimer's biomarkers in detecting imminent symptom progression. The discovery could reshape how clinicians identify at-risk patients before cognitive decline takes hold.

Brain–computer interface detects hidden awareness in unresponsive patients
Researchers at the University of Bath have developed a brain-computer interface capable of detecting signs of consciousness in patients who appear completely unresponsive after severe brain injury. The technology identifies hidden awareness that traditional clinical assessments would likely miss. For patients and families navigating disorders of consciousness, this could be a critical step toward more accurate diagnoses and informed care decisions.
