Water droplets simply roll off - and clean the surface and reduce infestation with fungal spores, for example. But not only plants have the "lotus effect," which Professor Wilhelm Barthlott of the University of Bonn discovered four decades ago. Land living Cyanobacteria (Hassallia byssoidea) also use extreme water repellency to protect themselves from water films and competitors. That's according to a research team led by Barthlott in the journal Frontiers in Plant Science. 

Life and health matter(s): At an exceptional networking event, members of the Transdisciplinary Research Areas "Building Blocks of Matter and Fundamental Interactions" (Matter) and "Life and Health" at the University of Bonn got to know each other and exchanged ideas.

Plesiosaurs, which lived about 210 million years ago, adapted to life underwater in a unique way: their front and hind legs evolved in the course of evolution to form four uniform, wing-like flippers. In her thesis supervised at Ruhr-Universität Bochum and the University of Bonn, Dr. Anna Krahl investigated how they used these to move through the water. Partly by using the finite element method, which is widely used in engineering, she was able to show that it was necessary to twist the flippers in order to travel forward. She was able to reconstruct the movement sequence using bones, models and reconstructions of the muscles. She reports her findings in the PeerJ magazine.

Since June 1, there is the 9-Euro-Ticket in Germany, with which one can use the public transport nationwide. Students at the University of Bonn can also benefit from this offer. Until the end of August, the extended area of use (Germany-wide on local public transport) applies to them. In addition, they will be refunded money paid over and above the 9 euros. The General Students' Committee (AStA) and the University administration have agreed on the modalities.

Code Intelligence, which grew out of a startup at the University of Bonn, is receiving $12 million in funding led by Tola Capital. Code Intelligence helps developers by providing a platform to find and fix security vulnerabilities before the product is finished. 

Mathematician Prof. Dr. Georg Oberdieck from the Hausdorff Center for Mathematics (HCM) at the University of Bonn has received this year's Dubrovin Medal from the renowned research institute SISSA in Italy. The medal is a special prize that recognizes exceptionally promising young researchers who have made outstanding contributions to the fields of Mathematical physics and Geometry.

"An apple a day keeps the doctor away" is an old English saying that means apples are healthy, so you should eat one every day. A very special specimen is the type "Adams Parmäne", which is currently on the red list of endangered native crops in Germany. The Wiesengut Teaching and Research Station at the University of Bonn is working with pomologist Barbara Bouillon from the "Biologische Station im Rhein-Sieg-Kreis" to preserve this special apple variety. She shows how this can work and why it is so important right now.

Several hundred settlements from the time between 500 and 1400 AD lie in the Bolivian Llanos de Mojos savannah and have fascinated archaeologists for years. Researchers from the German Archaeological Institute, the University of Bonn and the University of Exeter have now visualized the dimensions of the largest known settlement of the so-called Casarabe culture. Mapping with the laser technology LIDAR indicates that it is an early urbanism with a low population density - the only known case so far from the Amazon lowlands. The results shed new light on how globally widespread and diverse early urban life was and how earlier societies lived in the Amazon. The study appeared in the journal Nature.
