Od karnevalu v Riu de Janeiru až po miláčky pirátů: papoušci jsou pro lidi na celém světě synonymem barevnosti. Mezinárodní konsorcium vedené vědci z portugalského BIOPOLIS-CIBIO právě publikovalo studii v jednom z nejprestižnějších vědeckých časopisů Science, ve které odhalilo, jak krásné zbarvení papouščího peří vzniká. Na studii se kromě portugalských a amerických akademiků významně podíleli také tři čeští vědci. Doktor Jindřich Brejcha z katedry filosofie a dějin přírodních věd Přírodovědecké fakulty Univerzity Karlovy, který je jedním ze tří hlavních autorů studie, a dále docent Peter Mojzeš z Matematicko-fyzikální fakulty Univerzity Karlovy a doktor Petr Maršík z České zemědělské univerzity.
