Making and controlling crystals of light
EPFL scientists have shown how light inside optical on-chip microresonators can be crystallized in a form of periodic pulse trains that can boost the performance of optical communication links or endow ultrafast LiDAR with sub-micron precision. Optical microresonators convert laser light into ultrashort pulses travelling around the resonator's circumference.

Closing in on elusive particles
In the quest to prove that matter can be produced without antimatter, the GERDA experiment at the Gran Sasso Underground Laboratory is looking for signs of neutrinoless double beta decay. The experiment has the greatest sensitivity worldwide for detecting the decay in question. To further improve the chances of success, a follow-up project, LEGEND, uses an even more refined decay experiment.

A new alphabet to write and read quantum messages with very fast particles
A new alphabet to write and read quantum messages with very fast particles
The interplay of quantum mechanics and special relativity requires a new alphabet to send reliable quantum messages Quantum information relies on the possibility of writing messages in a quantum particle and reading them out in a reliable way. If, however, the particle is relativistic, meaning that it moves with velocities close to the speed of light, it is impossible for standard techniques to unambiguously decode the message and the communication fails.

The Chemistry of Art: Scientists Explore Aged Paint in Microscopic Detail to Inform Preservation Efforts
Study involving X-ray imaging at Berkeley Lab provides clues to how artwork composed of oil paints can deteriorate over time Watching paint dry may seem like a boring hobby, but understanding what happens after the paint dries can be key in preserving precious works of art. The formation of metal soaps in artwork composed with oil paints can cause "art acne" - including pimpling and more severe deterioration - which poses a pressing challenge for art conservation around the globe.

Providing a solution to the worst-ever prediction in physics
A UNIGE physicist has proposed a new approach to solving one of the biggest theoretical problems in physics: the cosmological constant. The cosmological constant, introduced a century ago by Albert Einstein in his theory of general relativity, is a thorn in the side of physicists. The difference between the theoretical prediction of this parameter and its measurement based on astronomical observations is of the order of 10121.

New biosensor provides insight into the stress behaviour of plants
They are tiny signalling molecules that play important roles in many processes in living organisms. However, the exact function of these substances is often still unknown, which is why scientists are constantly on the lookout for new methods with which they can further investigate them. Researchers at the Universities of Münster and Nanjing (China) have developed such a method for an important messenger substance in plants, called phosphatidic acid.

Scientists harness bacteria to create ’living’ liquid crystals
Liquid crystals are widely used in technologies such as displays, which manipulate their orientation to display colors across the spectrum. In traditional displays, liquid crystals are stationary and uniform, free of defects. But that stillness can be altered by adding bacteria to the crystals, creating what scientists and engineers call "living liquid crystals": materials that can act autonomously.
