Summary

Story summary

Chemists at the University of California, Riverside (UCR) have stabilized a reactive carbene in water.
The result confirms Ronald Breslow's 1958 hypothesis that vitamin B1 forms a carbene to drive reactions.
Researchers describe a protective "armor" that keeps the carbene intact for months.
The study, published in Science Advances, suggests safer, water-based routes for pharmaceuticals by reducing toxic solvents.
It also deepens understanding of chemical processes in living cells.
