A research team led by Prof. GE Ziyi and Prof. LIU Chang at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences has developed a chemical-hardness-guided strategy to control crystallization in all-perovskite tandem solar cells—achieving a certified power conversion efficiency of 30.3% in rigid devices and 28.0% in flexible tandems.

A new study led by Prof. YAN Xiaoyuan from the Institute of Soil Science of the Chinese Academy of Sciences has overturned the long-held assumption about nitrogen loss in agriculture. Published in PNAS on April 22 as a cover article, the study reveals that most nitrogen gas (N₂) emissions from rice paddies originate from soil organic nitrogen (SON), rather than applied fertilizers.

The Large High Altitude Air Shower Observatory (LHAASO) has detected PeV (10¹⁵ eV) gamma-ray emission from a pulsar wind nebula powered by PSR J1849-0001 in the constellation Aquila, marking the discovery of a new PeVatron and posing a challenge to the classical theory of particle acceleration in pulsar wind nebulae.

Scientists from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences have uncovered the earliest fossil evidence of annelids (ringed worms) in Cambrian microfossils dating back approximately 535 million years ago. This discovery offers fresh insights into the origin and early evolution of the annelids, a group of animals that includes bristle worms, earthworms, leeches, and peanut worms.

A collaborative research team led by scientists from the China National Center for Bioinformation, a research center affiliated with the Chinese Academy of Sciences (CAS), together with the CAS Institute of Zoology and Quzhou Affiliated Hospital of Wenzhou Medical University, has constructed a high-precision Human Immune Aging Clock (HIAC). The work systematically characterizes the multiscale dynamics of immunosenescence and identifies the transcription factor RUNX1 as a functional "brake" on T-cell senescence.
