Those who do not reproduce live longer

Children or a long life? This question actually arises in nature. Together with international colleagues, researchers in Leipzig have studied 117 mammal species. The result: animals whose reproduction is prevented live on average ten percent longer. The reason lies in evolution. Every living creature has to divide its energy between producing offspring and maintaining its own body. The study shows how this balance works and what it means for humans.

Leipzig team decodes brain changes with mathematics

Which brain regions change with age? Where does the brain work differently in autism? Researchers from the Max Planck Institute in Leipzig have developed a mathematical method that answers precisely these questions. A new metric identifies 108 regions that are affected by ageing and 27 regions that are altered in autism spectrum disorders. The findings could pave the way for targeted therapies.
