Digital images that have been tampered with could now be spotted – thanks to a digital ‘watermark’ developed by UK scientists
Digital images such as CCTV footage are increasingly being used as evidence in high profile court cases. However, it is easy to tamper with an image and very difficult to tell if any manipulation has taken place.
Researchers have created a digital version of a watermark to tackle this problem and validate digital evidence. The team is led by Professor Dave Bull at the University of Bristol and funded by the Swindon based Engineering and Physical Sciences Research Council.

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.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
