Researchers uncover oldest 3D burrow systems in Hubei's Shibantan Biota

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A research team from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences has made progress in studying the Shibantan Biota in Yichang, Hubei Province, uncovering the oldest known complex three-dimensional burrow systems to date. Preserved in approximately 550-million-year-old strata, these trace fossils show that complex animal behaviors were modifying the seafloor environment nearly 10 million years earlier than previously thought.

3D DNA looping discovery in rice paves the way for higher yields with less fertilizer

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A team of Chinese scientists has uncovered a hidden 3D structure in rice DNA that allows the crop to grow more grain while using less nitrogen fertilizer. The finding, published in Nature Genetics by researchers from the Chinese Academy of Sciences (CAS) on Oct. 29, could guide the next "green revolution" toward higher yields and more sustainable farming.

China's cropland acidification has ceased—but recovery is slow

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A new study led by Profs. YAO Yijun and LUO Yongming from the Institute of Soil Science of the Chinese Academy of Sciences shows that the steady acidification of China's cropland soils, which began in the 1980s, stabilized around 2013.

Ocean iron fertilization or artificial ocean alkalinization? Study reveals divergent effects on climate

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

The study reveals that OIF promotes marine carbon sinks by adding iron to “high-nutrient, low-chlorophyll” marine regions (e.g., the Southern Ocean), which enhances the photosynthesis of surface phytoplankton and thereby increases marine carbon sinks. In contrast, AOA improves seawater alkalinity by adding alkaline materials (such as limestone) to the ocean; through carbonate chemical processes, this method drives the ocean to absorb more CO₂ from the atmosphere.

Milli-volt breakthrough: optoelectronic polymer memristors redefine edge computing

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

Researchers in China have developed ultra-low voltage optoelectronic polymer memristors capable of dynamic, multifunctional integration for efficient edge computing. Operating at mere millivolt levels, these devices deliver high accuracy in fingerprint recognition, significantly streamlining system architecture and reducing manufacturing costs, paving the way for the next generation of flexible electronics.

Laser-emission vibrational microscopy enables rapid screening of hyperlipidemia

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

The mechanical properties of biological fluids can act as early indicators of disease, reflecting subtle physiological and pathological changes. However, current technologies face challenges in achieving high-throughput measurements, which limits their broader application in clinical diagnostics. To address this issue, the researchers developed a laser-emission vibrational microscopy technique based on whispering gallery mode laser, enabling rapid, high-throughput analysis of fluid mechanical properties. The method demonstrated strong potential for large-scale and efficient screening of hyperlipidemia.
