Chromo-encryption method encodes secrets with color
Research
EPFL
In a new approach to security that unites technology and art, EPFL researchers have combined silver nanostructures with polarized light to yield a range of brilliant colors, which can be used to encode messages.
More light in the darkness
Research
PSI
The Standard Model of particle physics describes our visible universe with incredible precision. Yet researchers are not entirely satisfied with it and are trying to find gaps in the theory. PSI’s unique infrastructures play a key part in their mind-boggling experiments.
Ultrafast control of spins in a microscope
Research
EPFL
Researchers at EPFL have developed a new technique that can visualize and control the rotation of a handful of spins arranged in a vortex-like texture at the fastest speed ever achieved. The breakthrough can advance “spintronics”, a technology that includes new types of computer memory, logic gates, and high-precision sensors.
Deflecting lightning with a laser lightning rod
Research
EPFL
A European consortium involving EPFL has managed to guide lightning using a high-power laser installed at the top of Mount Säntis in Switzerland.
The best of both worlds
Research
PSI
Annalisa Manera’s career has taken her through half of Europe and to the USA. Now she is a nuclear researcher at PSI and a professor at ETH Zurich. She exudes enthusiasm for her subject and never loses sight of the big picture.
Scientists delve into natural slicks on Lake Geneva
Research
EPFL
An EPFL researcher has, for the first time, documented slicks – those visually arresting, moving patches of smooth water – and explained what is happening beneath the surface.
