Optical frequency combs technology has become a core technology in information systems over last decade. Recently, UCLA reported groundbreaking research in eLight demonstrating chip-level platicon frequency microcombs achieving free-space terabit coherent optical communication. In a 160-meter link, data transmission reached 8.21 Tbit/s and remained stable under turbulence, offering innovative solutions to meet the high-bandwidth demands of 6G networks and communications.

POSTECH Team unveils new technology that uses light’s color and spin to display multiple images.

How long have you been doing your current job? Have you ever thought about trying a new profession? How difficult does change seem to you? The current rapid transformation of the labor market is putting many workers to the test: they struggle to keep up and move into new roles, while at the same time companies are having difficulty finding qualified personnel. A new study has analyzed the French labor market using methods from statistical physics, and found that over 90% of jobs today function as bottlenecks: they are easily accessible, but once entered, they become traps from which it is hard to move elsewhere—even when other opportunities are available.

The study, conducted by Max Knicker, Karl Naumann-Woleske, and Michael Benzaquen of École Polytechnique in Paris, and published in the Journal of Statistical Mechanics: Theory and Experiment (JSTAT), provides a detailed mapping of accessibility and transferability characteristics within the French occupational network. It reveals strong structural rigidity in the overall labor system and offers a basis for understanding what kinds of interventions and policy decisions might help to break this deadlock.

Experimental studies under atmospheric conditions show two important reaction pathways in the hydroxyl radical-initiated degradation of isoprene, which form highly oxidised peroxy radicals with 8 or 9 oxygen atoms and may be of global importance for the production of organic aerosols.

Highly sensitive detection methods allow ever deeper insights into complex chemical processes in the atmosphere: Researchers at the Leibniz Institute for Tropospheric Research (TROPOS) in Leipzig found a series of new product channels in a detailed product study on the oxidative degradation of isoprene in the gas phase, which allows a better mechanistic understanding of this important process for atmospheric chemistry. The results were published in the journal Nature Communications.
