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.

A unusual preservative in specimen jars has proven to be a solution for studying changes in genetic diversity among fish populations in the Philippines since the early 1900s.

Museum samples from the USS Albatross, including those preserved in high-proof alcohol, have been used in this research.

Unusual preservative in specimen jars proved to be a sweet solution for studying changes in genetic diversity among fish populations in the Philippines since the early 1900s.

Author's summary: High-proof alcohol preserves fish DNA for genomic study.
