Next-generation printing: precise and direct, using optical vortices

Will printed photographs ever match the precision of a mirror’s reflection? Even though the answer may still be no for a while, Osaka Metropolitan University scientists have made significant strides in precision printing with their innovative optical vortex laser-based technique that allows for the precise placement of minuscule droplets with micrometer-scale accuracy.

FAU Invention for Maximum Privacy of Sharing Files Online Gets U.S. Patent

While services such as Snapchat allow self-destructing messages or notify users when a recipient takes a screenshot of a message, there is no way to prevent someone from photographing or showing it to others on the screen.
