The new cabinet threatens to cut nearly a billion euros from higher education. This not only endangers academic work, it is a disaster for the Netherlands itself. The proposed penalty on study extensions and other financial measures will heavily impact students and will reduce education accessibility.…

Kidney failure is a serious issue because kidneys cannot regenerate themselves after injury. A possible solution consists of artificially growing healthy kidney tissue. To achieve that, scientists first need to understand kidney development during the earliest stages, in the fetus. Leiden researchers…

The surface and the edges of graphene are expected to provide higher sensitivity and specificity in detecting and characterizing single molecules. However fundamental physical limits exist in reaching an ultimate precision in detecting the dynamics of chemical and biological systems. The research in…
