Aftermath. stage to the biobank earlier this week.

hundreds weekend floods in Copenhagen destroyed cell lines Biobank of the Danish Cancer Society. Scientists are still working to assess the full damage, says Jørgen Olsen, head of the biobank; they were able to recover more than 1 million tissue samples, however, including a prospective study of nutrition and cancer for 20 years.
Heavy rains flooded the streets and sewers of Copenhagen on Saturday, causing considerable damage in the city. the basement of the cancer society filled with 2 meters of water in about half an hour on Saturday night, says Olsen. "This was about 20 centimeters too high for freezers," he said, which filled with water, thaw cell lines and tissue samples. The researchers are not able to reach their samples to the Sunday mid-day, when the water had partially retreated. Right now, a refrigerated truck arrived Jutland, allowing refreeze samples researchers.
The cell lines are unlikely to survive the thawing, but the tissue samples are less delicate, Olsen said. "It does not matter that they have been warmed for a few hours, as long as you freeze again," he said. Some of the lost cell lines were shared with other laboratories and can be retrieved, but Olsen believes that dozens have been permanently lost. He said the cleaning and complete assessment of the damage will take months.
