Summary

Story summary

Researchers in Romania discovered the bacterial strain Psychrobacter SC65A.3 in 5,000-year-old ice from Scarisoara cave, which resists 10 modern antibiotics.
This strain thrives in cold environments and poses no threat to humans, highlighting natural antibiotic resistance evolution over millions of years.
As glaciers melt due to climate change, dormant microbes may be released, potentially impacting ecosystems.
The strain shows promise for developing new antibiotics by secreting molecules that kill resistant bacteria, emphasizing the need for new antibiotic candidates.
