Forging wills and bank cheques could now be near impossible thanks to a team of physicists in Rome (Italy). Writing in the latest issue of the Institute of Physics journal, Journal of Optics A, the scientists announce a new technique that can detect forged handwriting better than ever before.
Professor Giuseppe Schirripa Spagnolo, Carla Simonetti and Lorenzo Cozzella from the Università degli Studi “Roma Tre” in Rome, Italy, have devised a forgery detection method that creates a 3D hologram of a piece of handwriting and analyses tiny variations and bumps along its path using two common scientific techniques: virtual reality and image processing.
Until now, detecting forged signatures or handwriting has generally been done by experts who analyse the sequence of individual “strokes” in a piece of handwriting using normal, 2D samples. However, a good forgery can go undetected at the 2D level because it isn’t always easy to determine the exact sequence of strokes.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
