High-Proof Alcohol Preserves Century-Old Fish DNA
Researchers have discovered that high-proof alcohol can preserve century-old fish DNA, enabling "genomic time travel".
A unique preservative in specimen jars has proven to be a valuable solution for studying changes in genetic diversity among fish populations in the Philippines since the early 1900s.
Museum samples from the USS Albatross, photographed by John Whalen, Old Dominion University, were used in the study.
At the annual meeting of the Ecological Society of America in Baltimore, a presentation titled
"Of rum and fishes: genomic change at ecological timescales in the ocean"stood out for its innovative approach.
Author's summary: Alcohol preserves old fish DNA for study.
- Researchers from the University of California, Santa Cruz, presented their work at the meeting.
