Dr. Omlor has developed a method to test medical heart-lung machines using human blood, instead of implanting them in living animals. Dr. Herrmann wants to avoid animal testing as well through her experiments on zebrafish larvae. The zebrafish embryos and larvae used are up to 5 days old and are not yet considered experimental animals at this stage, but they already have developed organs. Another advantage compared to adult animals such as fish or mice is their high genetic similarity, explains Franziska Fries of the Helmholtz Center in a video report by Saarländischer Rundfunk.

The prize is worth 10,000 euros and was awarded half to each of the prize winners.
It is awarded every two years.
