Recently, a research team led by Prof. XU Yigang and Prof. LIN Mang from the Guangzhou Institute of Geochemistry of the Chinese Academy of Sciences identified seven olivine-bearing clasts from two grams of lunar regolith returned by the Chang'e-6 mission. Their findings were published in Proceedings of the National Academy of Sciences (PNAS) on Oct. 20.

Researchers discovered a previously unknown solar radio pattern — periodic beaded stripes — using the Chashan Broadband Solar Radio Spectrometer during a 2024 flare. These narrow, drifting radio bands, dotted with rhythmic “beads”, reveal rapid plasma processes in the Sun’s corona. The team attributes their formation to the double plasma resonance effect, modulated by magnetohydrodynamic waves. Observations suggest a weak magnetic field (~1 G) above the flaring loops in an active solar region.

The National Institute of Information and Communications Technology (NICT) and the Nagoya Institute of Technology (NITech), collaborated with the Japan Aerospace Exploration Agency (JAXA), have achieved the world’s first successful demonstration of next-generation error correction codes, mitigating the impact of atmospheric turbulence on ground-to-satellite laser communications.

Atmospheric turbulence in ground-to-satellite laser links is known to cause fading, resulting in burst data errors. Error correction codes are one of the key technologies to mitigate such effects. In this experiment, we transmitted next-generation error correction codes with high correction capability (5G NR LDPC and DVB-S2) and successfully corrected burst data errors caused by atmospheric turbulence in the laser link. This result confirmed that both codes can significantly improve communication quality compared to conventional schemes.
