A chance find by a high school student led to the youngest, smallest and most complete fossil skeleton yet known from the iconic tube-crested dinosaur Parasaurolophus. The discovery, announced today by the Raymond M. Alf Museum of Paleontology at The Webb Schools, shows that the prehistoric plant-eater sprouted its strange headgear before it celebrated its first birthday. Three-dimensional scans of nearly the entire fossil are freely available online, making this the most digitally-accessible dinosaur to date.

Recycling or "scrap press": physicians at the Ruhr-Universität have found out which molecular mechanisms decide about the fate of the import receptor Pex18. Pex18 is responsible for the import of proteins into specific cell components, namely peroxisomes. Two opposing regulatory circuits determine whether the receptor remains active or is broken down after the transport has been completed. "Thus, the picture of the regulation of the protein import into peroxisomes has been completed and integrated to form one single model," says Junior Professor Dr Harald Platta from the RUB Faculty of Medicine. Together with Prof Dr Ralf Erdmann and other colleagues he reports in the journal "Traffic".
