Making history with 42 digits: Scientists at Paderborn University and KU Leuven have unlocked a decades-old mystery of mathematics with the so-called ninth Dedekind number. Experts worldwide have been searching for the value since 1991. The Paderborn scientists arrived at the exact sequence of numbers with the help of the Noctua supercomputer located there.

Researchers discover vulnerabilities in Microsoft Office application The problem affects signatures in Word documents, for example. Users who need to securely send an important Word document digitally can protect it with a digital signature. But as researchers from the Network and Data Security department at the Horst Görtz Institute for IT Security at Ruhr University Bochum, Germany, and the Mainz University of Applied Sciences have discovered, attackers can easily manipulate the document without being detected.

Creating trustworthy IT systems using cryptography Banking, emails, shopping: increasing volumes of data are being collected, processed and stored online. The challenge of ensuring that they are securely encrypted is similarly increasing, because in the future, quantum computers will be able to crack current encryptions.

"Flora Incognita," Germany's most popular plant identification app, has received new artificial intelligence - as a result, the number of plant species that can be determined has tripled: Around 16,000 species can now be identified worldwide. In addition, the app, which is now available in 20 languages, now also works in offline mode, and its digital educational offering includes a wealth of new information, such as improved distribution maps of many species.

When children develop their professional interests, the social environment is extremely formative. Girls often still lack female role models in the field of computer science. The university group she.codes wants to change that and get girls excited about programming. It is often said that IT is a man's world.

Research led by Göttingen University and EMBL develops new tool for sharing big image data High-resolution microscopy techniques, for example electron microscopy or super-resolution microscopy, produce huge amounts of data. The visualization, analysis and dissemination of such large imaging data sets poses significant challenges.
