Time-Gated Raman Spectroscopy Reveals How 3,000-Year-Old Sanxingdui Ivory Degraded—Despite Intense Fluorescence
Time-Gated Raman Spectroscopy Reveals How 3,000-Year-Old Sanxingdui Ivory Degraded—Despite Intense Fluorescence

A research team led by Dr. WANG Zhenyou, Research Fellow at the Aerospace Information Research Institute, Chinese Academy of Sciences (AIRCAS), has developed a microscopic time-gated Raman spectrometer that enables non-destructive, micrometer-scale chemical analysis of fragile archaeological ivory—even when strong fluorescence would normally obscure the signal. The study was published in ACS Applied Materials & Interfaces.

New Zero-Shot Learning Approach Advances Maize Phenotyping and Yield Estimation Without Model Retraining

A new study published in Smart Agricultural Technology introduces a zero-shot learning (ZSL) framework for maize cob phenotyping. This innovative pipeline enables accurate extraction of geometric traits and yield estimation in both laboratory and field environments without the need for model retraining.

Progress Persists for Low-Baseline SDGs, While High-Baseline Goals Stagnate or Reverse
Progress Persists for Low-Baseline SDGs, While High-Baseline Goals Stagnate or Reverse

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.
