Xigou site discovery challenges long-held views on early human technology in East Asia

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

Led by the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences, the team—which included researchers from China, Australia, Spain, and the United States—conducted multidisciplinary archaeological investigations at the Xigou site in the Danjiangkou Reservoir region of central China. Their work yielded evidence of sophisticated stone tool technologies dating from 160,000 to 72,000 years ago, revealing that hominins in the region were far more innovative and adaptable than previously thought.

Scientists reveal gold precipitation mechanism at pyrite–water interface

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

Using in situ liquid-phase transmission electron microscopy under conditions that excluded the influence of dissolved oxygen and electron beams, scientists have achieved the first nanoscale, real-time observation of the reaction between pyrite and gold-bearing solutions, providing critical insights into gold enrichment by pyrite.

Increased soil salinity alters global inorganic carbon storage

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A new global study ed by Prof. XUE Xian from the Northwest Institute of Eco-Environment and Resources of the Chinese Academy of Sciences shows that increasing soil salinity is systematically reshaping the storage and distribution of soil inorganic carbon (SIC), providing the first comprehensive global assessment of how soil salinization influences inorganic carbon storage and highlight its implications for the global carbon cycle.

Absolute thermometry based on Brillouin scattering in gases

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

Scientists have introduced the first absolute, contactless thermometry technique based on Brillouin scattering in gases, enabling high-accuracy temperature measurements from room temperature down to deep cryogenic levels. By filling hollow-core fibres with gases such as neon, argon, or helium, the method retrieves temperature directly from the Brillouin frequency shift via the interaction between laser light and acoustic waves, eliminating the need for calibration. The results pave the way for ultra-precise, minimally invasive thermometry in extreme environments.

Smart correction: gradient graphene enables self-aligned laser transfer

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

Conventional laser-assisted transfer technologies often suffer from limited fault tolerance during laser-matter interactions, where even slight laser irradiation deviations reduce transfer accuracy. Scientists from HUST have developed a Self-Aligned Laser Transfer (SALT) technique featuring a thermal-conductivity gradient carbon stamp. This innovative structure converts asymmetric light input into uniform heat output under misaligned laser irradiation, significantly reducing chip transfer errors and enabling high-precision, programmable assembly without requiring precise alignment.
