Amino acids and peptides may provide biodegradable glasses through a heating-quenching procedure Researchers led by YAN Xuehai from the CAS Institute of Process Engineering have fabricated a family of eco-friendly glasses of biological origin, using biologically-derived amino acids or peptides through heating-quenching, a classic industrial procedure. They chemically modified amino acids and peptides at their ends so they form a super-cooled liquid before decomposition. The glasses exhibited good […]

Calcium carbonate shells protect a probiotic during manufacture and GI passage A team from Shanghai Jiao Tong University has created a calcium carbonate coating using electrostatic interactions that mimic the mineral formation of biological tissues. The ultra-resistant coating which disappears during gastrointestinal passage was shown to protect the probiotics organism Bacteroides fragilis during production from oxygen, UV and ethanol, and during GI passage from […]

Global fires have strong impact on atmospheric CO2 Shi Yusheng’s research team of the CAS Aerospace Information Innovation Institute has quantified the impact of global fire carbon emissions on atmospheric carbon dioxide concentration. The research results show that the annual average impact of global fire carbon emissions on atmospheric carbon dioxide concentration can reach 2.4 ppm, indicating that fire is one […]

Peroxisome engineering provides pathway from methanol to fatty alcohols Zhou Yongjin and team at the CAS Dalian Institute of Chemical Physics have coupled methanol utilization with fatty alcohol biosynthesis through metabolic pathway compartmentalization in methanolic yeast. Normally, the yield of fatty alcohols synthesized by modified Hansenula polymorpha using methanol as raw material is very low due to the toxicity of methanol and […]

China’s capacity for renewable energies enough to fuel all 27 EU member states According to Song Kailiang, Chairman of the China Energy Construction group, China’s total installed capacity of renewable energy generation in 2022 exceeded that of coal power generation, accounting for 47.3% of the total, and the full-year generation volume exceeded 2.7 trillion kWh, which is equivalent to the annual power consumption of 27 European Union […]

China’s deep-sea manned submersible Fendouzhe completes dives in Oceania China’s deep-sea manned submersible Fendouzhe (Striver) returned to Sanya city, south China’s Hainan Province, on March 11, with fruitful results, according to the Institute of Deep-sea Science and Engineering of the Chinese Academy of Sciences. Fendouzhe completed 63 dives during its voyage aboard the country’s scientific research ship Tansuo-1 in the ship’s first international […]

Frequent social activities beneficial for older people (Xinhua) 13:32, March 14, 2023 BEIJING, March 14 (Xinhua) — Chinese researchers have discovered that frequent engagement in social activities is strongly associated with prolonged overall lifespan in older people. The issue of population aging poses a growing concern around the world. It is estimated that China will become a deeply aging society in 2027 […]

Graphene-based wearable artificial throat and AI may help laryngectomy patients Researchers from Tsinghua University and Shanghai Jiao Tong University School of Medicine have devised a graphene-based intelligent, wearable artificial throat (AT), sensitive to human speech and vocalization-related motions. The AT’s perception of the mixed modalities of acoustic signals and mechanical motions enables it to acquire signals with a low fundamental frequency while remaining noise resistant. It can […]

CAS DICP achieves improved photocatalytic production of hydrogen peroxide Two teams from CAS Dalian Institute of Chemical Physics and the University of Queensland, Australia, have made progress on artificial photosynthesis of hydrogen peroxide (H2O2) by simulating the stomatal structure of plant leaves , resulting in a solar-to-chemical (SCC) conversion rate of 1.23%. The collaborative team grew two-dimensional mesoporous resorcinol-formaldehyde (RF) resin on […]
