Dwarf galaxy clustering challenges standard cold dark matter paradigm

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A new study of diffuse dwarf galaxies is challenging the prevailing galaxy formation model within the standard Cold Dark Matter (CDM) framework, leading to a proposed new model of dark matter. Under the direction of Prof. WANG Huiyuan from the University of Science and Technology of China, the research team identified for the first time an exceptionally strong clustering pattern in diffuse dwarf galaxies.

Scientists reveal how deep-earth carbon movements shape continents and diamonds

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A new study led by researchers from the Guangzhou Institute of Geochemistry of the Chinese Academy of Sciences, along with international collaborators, reveals that deeply subducted carbonates can cause significant variations in the redox states of Earth's mantle. This process influences the formation of sublithospheric diamonds and plays a role in the long-term evolution of cratons—ancient stable parts of the continental lithosphere.

Researchers reveal structure and activation mechanism of prostaglandin E2 receptor EP1

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

The researchers used cryo-electron microscopy (cryo-EM) to determine the structure of the human EP1 receptor in complex with PGE₂ and the heterotrimeric Gq protein, completing the structural atlas of the EP receptor family. They also revealed EP1-specific mechanisms of ligand recognition and signal transduction.

Researchers elucidate mechanism of auxin influx in plants

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

Researchers from the University of Science and Technology of China of the Chinese Academy of Sciences have unveiled the structures of Arabidopsis AUXIN RESISTANT 1 protein (AUX1) and clarified the molecular mechanism by which this protein transports auxin into the cell via the proton concentration gradient.

Chinese researchers reveal lipid-based communication between body and gut microbes

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A team of researchers from the Shanghai Institute of Nutrition and Health and the Center for Excellence in Molecular Cell Science uncovered a surprising new way that the body interacts with gut microbes to help maintain intestinal health.

New study shows how ancient climates may inform monsoon prediction

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A recent study published in Nature has explored how the South Asian Summer Monsoon (SASM) responds to warming under six climate scenarios, spanning from the past to the future. Led by researchers from the Institute of Atmospheric Physics at the Chinese Academy of Sciences, the study develops a unified framework based on thermodynamic (moisture-driven) and dynamic (wind-driven) processes that govern changes in the SASM, suggesting that insights from past warm climates can inform our understanding of the future SASM.
