The world`s oldest fossilised vomit, believed to have come from a large marine reptile that lived 160 million years ago, has been discovered in a clay quarry in Peterborough by the University of Greenwich`s Professor Peter Doyle and Dr Jason Wood of the Open University.
The vomit contains the remains of dozens of belemnites - squid-like shellfish that lived in abundance in the seas around what is now Britain. The belemnites were eaten in great numbers by ichthyosaurs, large marine reptiles (related to land-dwelling dinosaurs) common in the warm seas of the Jurassic era, similar in size and shape to dolphins.
Having eaten dozens of belemnites, an ichthyosaur would regurgitate their indigestible bullet shaped shells in much the same way that an owl does after eating a mouse whole. It is these shells that have been discovered in the fossil vomit.

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
