Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

The Large High Altitude Air Shower Observatory (LHAASO) has made a breakthrough in exploring the extreme universe. For the first time, the LHAASO collaboration has detected ultra-high-energy (UHE) gamma rays—with energies exceeding 100 trillion electron-volts (TeV)—from a gamma-ray binary system, LS I +61° 303.

Study reveals soil, not fertilizer, is primary source of nitrogen gas loss in rice paddies

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

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.

Earliest Cambrian microfossils preserve ringed worms

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

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.

Gene discovery opens new path for disease-resistant rice breeding

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

Prof. HE Zuhua's team from the Center for Excellence in Molecular Plant Sciences of the Chinese Academy of Sciences, along with collaborators, cloned the broad-spectrum BB resistance gene Xa48. They elucidated a new model for broad-spectrum, durable BB resistance involving an NLR immune receptor and its cognate effector, and revealed the molecular mechanism by which XA48 coordinates growth and immunity during crop domestication.

Researchers develop high-precision human immune aging clock, identifying RUNX1 as key target for T-cell senescence

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

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.

Researchers identify key gene for perennial growth in wild rice

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

The research groups led by HAN Bin and WANG Jiawei from the Center for Excellence in Molecular Plant Sciences have cloned Endless Branches and Tillers 1 (EBT1), a key gene that determines whether wild rice grows as a perennial, and revealed that changes in the expression pattern of this gene underlie the transition of rice from perennial to annual during domestication.

Researchers Elucidate Complete Biosynthesis of Nicotine

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A research group led by Prof. LI Dapeng from the Center for Excellence in Molecular Plant Sciences elucidated the complete biosynthetic pathway of nicotine in the wild tobacco species Nicotiana attenuata using an information theory-guided multidimensional omics approach. The results revealed a five-component dynamic metabolon that orchestrates the final condensation steps of nicotine synthesis and its transport.

New study reveals shallow mantle source for supervolcanic magma

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A research team from the Institute of Geology and Geophysics of the Chinese Academy of Sciences (IGGCAS) has developed a comprehensive three-dimensional geodynamic model of western North America that simulates the present-day dynamics of both the lithosphere and the underlying convecting mantle, revealing a mechanism for magma generation beneath supervolcanoes.

Chang'e mission samples reveal how exogenous organic matter evolves on the Moon

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A recent study has for the first time systematically identified multiple nitrogen-bearing organic species on the surfaces of lunar soil grains returned by China's Chang'e-5 and Chang'e-6 missions. The research further reveals an evolutionary pathway defined by exogenous delivery, impact modification, and continuous solar wind processing.

Non-destructive homogeneity measurement for transparent cylindrical materials without slicing

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS
Peer-Reviewed Publication

Current homogeneity testing has long relied on a planar “slice‑then‑measure” approach. Professor Sen Han’s team proposes a radial absolute measurement method for cylindrical surfaces. This method requires no slicing, is low‑cost, and enables direct non‑destructive measurement of refractive index distribution, offering an efficient pre‑screening tool for semiconductors, LiDAR, medical imaging, and more.

Fiber endoscopy: Physics-guided network erases honeycomb artifacts

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS
Peer-Reviewed Publication

Lensless multi-core fiber endoscopes suffer from honeycomb-like artifacts that obscure fine structures. To overcome this, researchers from Tsinghua University and Technische Universität Dresden developed SGARNet, which allows us to cleanly erase long-standing honeycomb artifacts via the frequency domain, bypass the need for massive paired data, and seamlessly recover high-fidelity images. The technique will open new avenues for future minimally invasive diagnostics and advanced endoscopic technologies.
