Iron-oxide nanozymes: catalytic adjuvants for mucosal influenza vaccination

A group around Dr. GAO Lizeng from the CAS Institute of Biophysics (IBP) has found that a chitosan- functionalized iron oxide nanozyme (IONzyme) functions as a catalytic adjuvant to enhance nasal mucosal immunity. The modified nanozyme combines with flu virus particles loaded with negative charges to produce the composites of nanozyme and inactivated flu virus, thus promoting the […]

Injectable hydrogel accelerates wound healing in mice

A consortium around Xiaoli ZHAO at CAS Shenzhen Institutes of Advanced Technologies prepared a hydrogel composed of catechol-modified quaternized chitosan and poly(d,l-lactide)-poly(ethylene glycol)-poly(d,l-lactide, loaded with bioactive glass. When the hydrogel formed after injection into ruptured skin of mice, the skin was sealed and wound healing was accelerated, probably due to endothelial cells migration and angiogenesis stimulated […]

Qatar and China cooperate in digital water-saving irrigation

An irrigation system developed by Ningxia University includes technologies and equipment involving wind-solar-powered water extraction, underground seeping pipes and a control software system operated on smartphones. It has been alredy applied over a total area of 575,733 hectares in northwest China, Oman and Egypt and will now be installed in Qatar in a project worth […]

4-Vinylanisole (4VA, 4-methoxy styrene) is responsible for swarm behavior of locusts: CAS Institute of Zoology

Locust swarms have recently devastated large agricultural areas in Eastern Africa and Southern Asia. A team around Xianhui WANG and Le KANG at CAS Institute of Zoology and CAS University of Science and Technology has investigated 35 odorous compounds emitted by locusts and their interaction with over 100 locust receptors, with the result that 4VA […]

Synthetic biology turns E. coli into a methylotroph

The team of James C. LIAO at the Institute of Biological Chemistry of Academica Sinica in Taipei, Republic of China, has reprogrammed E. coli using metabolic robustness criteria followed by laboratory evolution to establish a strain that can efficiently utilize methanol as the sole carbon source and grows to high cell density at a rate […]
