Most people interested in animal-free methods probably don't have the opportunity to go to a laboratory and be shown and explained the new methods. A movie can replace this. A clear explanation with moving images makes it easier to understand the new techniques and raise awareness that there are methods other than animal testing. In his film, the enthusiastic filmmaker Marc Pierschel lets well-known researchers have their say, presenting their developments and explaining them in a vivid way.

A team at Kyoto University has developed a human induced pluripotent stem cell-derived proximal tubule-on-chip (OPTECs-on-chip). It has the necessary functionality and polarity of important kidney transporters. According to the developers, the kidney chip model can therefore be used to assess drug transport and nephrotoxicity.

With the Hamburg Research Prize for Alternatives to Animal Testing, the the Hamburg Senate wants to actively support the development towards a future without animal testing, says Science Senator Katharina Fegebank (Bündnis 90/die Grünen) in the current press release. The prize was divided among three winners.

Every year, the BMEL announces an animal welfare research prize with a total prize money of 25,000 euros. However, everything is different this year: The prize has been redesigned. It will be awarded in three categories and the prize money amounts to a total of 220,000 euros. And there's something else that's different.
