Goldfish turn to alcohol to survive icy winters

Scientists have decoded the secrets behind a goldfish’s ability to survive in ice-covered lakes.

They’ve worked out how and why the fish turn lactic acid in their bodies into alcohol as a means of staying alive and say the work may help with the study of some alcohol impacts in humans, says a report in the journal Scientific Reports.

Goldfish and their wild relatives, crucian carp, are able to survive for months in icy conditions in ponds and lakes in northern Europe.
