High-Proof Alcohol Preserves Century-Old Fish DNA
High-proof alcohol has been found to preserve century-old fish DNA, enabling "genomic time travel" to study changes in genetic diversity among fish populations in the Philippines since the early 1900s.
Museum samples from the USS Albatross, preserved in specimen jars with an unusual preservative, proved to be a valuable solution for this research.
A presentation at the annual meeting of the Ecological Society of America in Baltimore highlighted this discovery, with the buzzworthy title:
“Of rum and fishes: genomic change at ecological timescales in the ocean”
Researchers from the University of California, Santa Cruz, showcased their work, demonstrating the strength of ecology and evolutionary biology research at the university.
Author's summary: Alcohol preserves old fish DNA for study.
