Research links trilobite body size changes in early Paleozoic with marine oxygen levels

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A recent study shows that marine oxygen levels were crucial to the evolution of Early Paleozoic trilobite body size, suggesting that oxygen may have influenced the evolution of other animals' body size as well.

Researchers reveal how human genetics and intratumoral microbiota affect colorectal cancer

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A recent study led by the Guangzhou Institutes of Biomedicine and Health of the Chinese Academy of Sciences has focused on this relationship and its effect on colorectal cancer. The study shows that the single-nucleotide polymorphism rs2355016—a tiny DNA change that some people carry—affects how intratumoral microbiota adhere to tumor cells, promoting CRC progression.

Iron carbide: a novel heterogeneous catalyst for deoxygenative C-C coupling of alcohols

Dalian Institute of Chemical Physics, Chinese Academy Sciences
Peer-Reviewed Publication

An innovative strategy to produce bibenzyls from the deoxygenative homocoupling of benzyl alcohols under ~~the~~a hydrogen atmosphere was developed using iron carbide catalysts. A variety of benzyl alcohols could be efficiently converted into the corresponding bibenzyls over the optimized Ir_0.1/Fe⁰@Fe₅C₂ catalyst, and a three-component coupling reaction mode was also discovered when alkenes were introduced. Based on control experiments and spectroscopy studies, a reaction mechanism involving C-O bond activation over iron carbide and the formation of benzyl radical species was proposed.

Vegetation changes accelerated climate shifts during the late Miocene, study finds

Institute of Atmospheric Physics, Chinese Academy of Sciences
Peer-Reviewed Publication

A new study reveals that vegetation shifts—triggered by global cooling and paleogeographic change—also accelerated major climate changes during the Late Miocene, creating a feedback loop.
