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.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
