Around 115 million years ago, the seas off northern Australia were home to a gigantic ancestor of Jaws. Fossils of this ancient mega-predator reveal that modern sharks experimented with enormous body sizes much earlier in their evolutionary history than previously suspected, and took the top place in oceanic food chains alongside massive marine reptiles during the Age of Dinosaurs. This study presents a new interdisciplinary analysis to reconstruct size evolution in ancient sharks.

In the current selection round, the German Research Foundation (DFG) has granted funding for two new Collaborative Research Centres at the University of Konstanz. Over the next four years, the research teams will be working intensively on trigger signals in biological cells as well as on "silence" and "noise" in human speech.

When conditions get too dry, Madagascar hissing cockroaches like to "cuddle". Under certain conditions, the large insects gather in groups, with many participants in physical contact with one another. According to recent research from Binghamton University’s Biological Sciences program, this strategy may prevent the cockroaches from drying out.
