Ultramicro iontronics enables dynamic tracking of cerebral chloride regulation

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

Researchers from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences have developed molecularly tailored liquid/liquid interfacial ultramicro iontronics (L/L UIs) for in vivo dynamic tracking of cerebral chloride (Cl^-) regulation.

Researchers develop polarization photodetector mimicking desert ant

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

Polarization photodetectors (pol-PDs) have widespread applications in geological remote sensing, machine vision, and biological medicine. However, commercial pol-PDs usually require bulky and complicated optical components and are difficult to miniaturize and integrate. Chinese researchers have recently made important progress in this area by developing an on-chip integrated polarization photodetector.

Chinese scientists propose strategy for increasing rice yield while reducing fertilizer use

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

Researchers from the Research Center for Eco-Environmental Sciences (RCEES) of the Chinese Academy of Sciences have developed a sustainable technology to selectively reduce nitrate to ammonium. This innovation delivers three benefits: It increases rice yield, reduces fertilizer usage, and mitigates nitrate pollution in groundwater. The findings were recently published in Proceedings of the National Academy of Sciences (PNAS).

Astronomers discover in situ spheroid formation in distant starburst galaxies

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

Researchers discovered evidence of in situ spheroid formation in distant starburst galaxies. Their findings were based on analysis of data from the Atacama Large Millimeter/submilllimeter Array (ALMA) on over 100 Submillimeter Bright Galaxies (SMGs). The SMGs featured redshifts from the “Cosmic noon” era of the Universe—between 8–12 billion years ago—when many galaxies were actively forming stars.

Scientists establish novel 2D "Health State Map" to define metabolic health

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

Chinese scientists have developed a novel two-dimensional (2D) framework, the "Health State Map (HSM)," to define metabolic health and nutritional capacity. The study was published online in <i>National Science Review</i>.

Scientists reveal possible role of iron sulfides in creating life in terrestrial hot springs

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

An international team of scientists recently published a study highlighting the potential role of iron sulfides in the formation of life in early Earth’s terrestrial hot springs. According to the researchers, the sulfides may have catalyzed the reduction of gaseous carbon dioxide into prebiotic organic molecules via nonenzymatic pathways.

Chinese scientists synthesize unsymmetrical ureas using non-phosgene method

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

Current industrial synthesis of urea compounds mainly uses a three-step method involving phosgene, which generates a large amount of corrosive hydrochloric acid. Now, however, a joint research group from China has achieved one-step carbonylative synthesis of unsymmetrical urea using a non-phosgene route.

Researchers reveal how aging impairs antitumor activity of CD8+ T cells

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A research team from the Shanghai Institute of Nutrition and Health of the Chinese Academy of Sciences revealed that aging specifically impairs the generation of CD8<sup>+</sup> tissue resident memory T cells (TRM) and thus compromises the antitumor defensive activity of aged CD8<sup>+</sup> T cells.

Researchers develop lysosomal “TRAP” for clearance of viruses and variants

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

Researchers from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences have recently developed a novel lysosomal strategy for clearing viruses and their variants. This lysosomal “TRAP” (lysoTRAP) shows potential for inhibiting infection by viruses and variants in cell, mouse, hamster, and human lung organoid models.

Researchers develop light-guided siRNA delivery system based on cyanobacteria

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A research team led by Prof. CAI Lintao from the Shenzhen Institutes of Advanced Technology of the Chinese Academy of Sciences reported its development of an innovative intelligent light-guided biohybrid system, the CTPA/siCSF1R system, to target tumor-associated macrophages (TAMs), thus enabling precise spatiotemporal siRNA delivery.
