Ancient Romanian Ice Bacteria Could Help Fight Superbugs—With Caution
Researchers studying a 5,000-year-old Psychrobacter strain from Romania’s Scărișoara Ice Cave found it resistant to multiple modern antibiotics yet capable of inhibiting several antibiotic‑resistant pathogens, suggesting ancient microbes could inspire new antibiotics but also carry a risk of spreading resistance genes if melted; calls for more research into cold-environment microbes and their biotechnological potential.
