Probiotic cream that ramps up heat production could prevent frostbite

5 hours ago

Scientists genetically engineered skin bacteria to produce more heat and detect temperature changes.
The engineered bacteria, Cutibacterium acnes, can produce twice as much heat as normal and flag high temperatures via a fluorescent signal.
A probiotic cream containing these bacteria could help prevent frostbite and hypothermia in extreme conditions.
The research was presented at the Synthetic Biology for Health and Sustainability conference in the UK.
Further testing is needed on human skin samples and mice to ensure safety and effectiveness.
Potential side effects, like overheating, could be managed by developing a method to kill the bacteria when needed.
