With only five years until the 2030 deadline for achieving the U.N. Sustainable Development Goals (SDGs), a new international study reveals uneven progress in achieving the goals since their adoption in 2015. The paper, recently published in Proceedings of the National Academy of Sciences (PNAS), reveals that global progress on numerous SDGs with high initial benchmarks has either stalled or gone into reverse. In contrast, SDG indicators with lower baseline performance continue to register gains. Researchers caution that the vast majority of countries will fail to meet their 2030 SDG targets under current trends.

The ability to generate and detect ultrashort light pulses in the ultraviolet UV-C range (100-280 nm) is crucial for many applications. This work demonstrates a UV-C source-sensor platform that combines nonlinear optical crystals for the generation of femtosecond UV-C laser pulses with photodetectors based on atomically-thin semiconductors. The platform has potential for different technologies, from broad-band imaging to spectroscopy on femtosecond timescales. As a proof of concept, the source-sensor is used to demonstrate free-space communication.
