A wheelchair directed by the blinks of your eye…

https://j.people.com.cn/n3/2026/0203/c95952-20422094.html

A professor at Qingdao University in Shandong Province has developed a groundbreaking system that generates electricity when people blink, supplying power to glasses that allow patients with amyotrophic lateral sclerosis (ALS) to control their wheelchairs simply by moving their eyes.

With conventional eye tracking devices, patients who wanted to operate a wheelchair and move around had to wear a heavy device on their head and be connected to a long electrical cord. Furthermore, alarms of low battery levels did discouraging patients from moving around on their own.

The eye tracking system of the team generates and supplies electricity by attaching dimethylpolysiloxane (PDMS)  to the surface of the user’s eyeball like a contact lens, creating a “micro-friction generator.” When the user blinks or moves their eyeball, friction occurs between the eyeball and PDMS, continuously generating electricity.

In an eyeglass frame worn by the user, transparent electrodes made of indium tin oxide are embedded, acting as a transducer. The transparent electrodes precisely track the distribution and changes of electric charge through electrostatic induction and convert it into a recognizable electrical signal in real time. This signal is then transmitted to an external device via a control circuit, ultimately enabling highly precise control.

Before this technology can leave the lab and be widely applied, however, a series of hurdles must be overcome for industrialization.

“Ramanomics” simplify quality control in beer brewing – QIBEBT

https://doi.org/10.1016/j.biortech.2025.133788

http://english.cas.cn/newsroom/research_news/life/202601/t20260114_1145714.shtml

Breweries typically monitor fermentation by analyzing broth composition. Alcohols, esters, acids and residual sugars are quantified via chromatography-based assays. While reliable, these tests are time-consuming and only yield batch-average results.

A research led by scientists from the CAS Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) has simplified this process and developed a novel workflow dubbed “process ramanomics,” which is based on spontaneous single-cell Raman spectroscopy.

To validate the approach, the researchers tracked an industrial beer fermentation process using the lager yeast Saccharomyces pastorianus, sampling a single production batch over an eight-day period. At each stage of fermentation, they collected high-throughput Raman spectra from individual cells (a “ramanome”) and matched these unique molecular fingerprints to conventional lab measurements of 43 extracellular phenotypes in the fermentation medium.

Using multivariate regression analysis, the team found that ramanomes could accurately predict 19 extracellular phenotypes. This included four higher alcohols, four esters, four amino acids, two organic acids, four mono- and disaccharide substrates, and the alcohol-to-ester ratio—a commonly used indicator tied to beer flavor balance. In practical terms, a single, rapid cellular analysis can now replace multiple time-intensive chemical assays—without sacrificing single-cell resolution details.

Because the models output cell-level predictions, the researchers also tracked phenotypic heterogeneity over time. Different metabolite classes displayed distinct heterogeneity trajectories, and for several phenotypes higher heterogeneity tended to accompany lower metabolite levels—suggesting that dispersion among cells may be a useful process-state indicator.

A novel artificial carbon fixation pathway LATCH with 10 enzymatic steps

https://www.sciencedirect.com/science/article/pii/S2950155525000667?via%3Dihub

https://www.cas.cn/syky/202511/t20251125_5089765.shtml

A research team at the CAS Tianjin Institute of Industrial Biotechnology has proposed a novel artificial carbon fixation pathway—LATCH which comprises 10 completely known enzymatic steps. Each cycle converts two molecules of HCO₃⁻ into one molecule of acetyl-CoA, requiring only adenosine triphosphate (ATP) and reduced coenzyme II for energy. Kinetic and thermodynamic modeling analysis shows that it is a linear autocatalytic cycle structure without kinetic traps or thermodynamic barriers, possessing high feasibility and potential for continued development. It can provide insights for improving the efficiency of systems such as photosynthetic microorganisms, plants, and engineered cell factories.

Regarding the selection of parental modules, the research team referenced research on the serine cycle and designed a modified version of the serine cycle, simplifying the pathway structure and bypassing the inefficient steps involving hydroxypyruvate, thus enabling the pathway to function effectively in the heterologous host *E. coli*. Simultaneously, the team replaced the amino acid deamination and transamination steps in the serine cycle with a decarboxylation process, forming an MCG cycle free from formic acid dependence. This cycle can further convert glycerate 3-phosphate produced by processes such as the Calvin cycle and glycolysis into acetyl-CoA in a negative carbon mode. The study also referenced a series of photorespiration bypass concepts developed for recovering the Rubisco byproduct glycolate-2-phosphate, among which the TaCo module, due to its artificial carboxylation reaction, theoretically has a maximum yield of 150%. This study found that by introducing glyoxylate reductase as a key step to act as a “molecular latch,” the natural serine cycle and the artificially carboxylated module TaCo can be recombined, resulting in a functional transformation—from two parent modules dependent on organic substrates to a complete carbon-fixing cycle.

Based on the LATCH cycle formed by module integration, kinetic analysis shows that this pathway is a linear autocatalytic cycle, theoretically avoiding kinetic traps while eliminating the need to establish complex regulatory relationships. Meanwhile, eight steps in the pathway receive thermodynamic support from adenosine triphosphate (ATP), reducing power, or high-energy substrates, and the remaining two lyase-catalyzed processes do not pose thermodynamic bottlenecks. These inherent advantages at the stoichiometric, kinetic, and thermodynamic levels lay the foundation for the continued development and application of LATCH.

Nature 2025 science city ranking: six of top 10 in China, Qingdao is 31 between Munich and Berlin

https://www.nature.com/nature-index/supplements/nature-index-2025-science-cities/tables/overall

https://en.people.cn/n3/2025/1118/c90000-20391615.html

The newly released “Nature Index 2025 Science Cities” supplement shows that the number of Chinese cities in the global top ten rose from five in 2023 to six in 2024, marking the first time China holds a majority in the rankings.

The supplement draws on the Nature Index database, which tracks research articles published from 2015 to 2024. Its analysis uses “Share”, a fractional count reflecting institutional contribution to publications, as the primary metric, with time-series data adjusted to 2024 levels. Each city’s Share is calculated by summing the contributions of all affiliated institutions located within that city.

According to the Nature Index, the world’s leading science cities overall are: Beijing, Shanghai, New York metropolitan area (U.S.), Boston metropolitan area (U.S.), Nanjing (China), Guangzhou (China), San Francisco Bay Area (U.S.), Wuhan (China), Baltimore-Washington metropolitan area (U.S.), and Hangzhou (China).

Further analysis shows that Chinese cities hold a strong advantage in chemistry, physical sciences, and earth and environmental sciences, leading the global rankings in all three fields. Notably, Chinese cities claimed all of the top ten positions in chemistry for the first time. In the other two subject areas, they secured six of the top ten spots, with Beijing ranking first worldwide across all three domains.

European cities in the ranking start at 19 (London), followed by Zurich (28), Cambridge (29), Munich (30) and Berlin (32), following Qingdao at position 31.

A new Fischer-Tropsch route which eliminates CO2 formation

https://en.people.cn/n3/2025/1031/c90000-20384954.html

https://www.science.org/doi/10.1126/science.aea0774

A group at Peking University has developed technology that almost completely eliminates carbon dioxide by-products during Fischer-Tropsch synthesis (FTS), offering a new route to green syngas conversion and low-carbon chemical manufacturing. FTS converts the syngas of carbon dioxide and hydrogen into liquid fuels or high-value chemicals such as olefins. It serves as the pivotal bridge for turning coal, natural gas, biomass and other carbon resources into fuels and value-added chemicals.

The researchers have used a sodium-modified FeCx@Fe3O4 core-shell catalyst coupling water-gas shift (WGS) with syngas-to-olefins (STO) to convert water into hydrogen in situ. HAE reaches about 66 to 83%, exceeding that of methanol-to-olefins (MTO, 50% upper limit). The approximately 95% carbon monoxide conversion and >75% olefin selectivity were simultaneously obtained. The coupling effect was validated by isotope tracing with deuterium oxide and blocking the WGS pathway, and the contribution of WGS was quantitatively evaluated. These results, using lower hydrogen to carbon monoxide ratios, implied that reducing steam consumption in the WGS reaction and reducing the overall output of carbon dioxide and wastewater enabled a sustainable STO process for potential industrialization.

An automated digital colony picker monitors growth and metabolite production, eliminating the need for culturing cells

https://www.nature.com/articles/s41467-025-63929-7

http://english.cas.cn/newsroom/research_news/life/202510/t20251014_1089412.shtml

The group around Jian XU from the CAS Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) has developed a fully automated “Digital Colony Picker” (DCP). This device identifies and retrieves high-performance microbial clones by simultaneously monitoring their growth and metabolite production—eliminating the need for culture plates, sampling needles, or manual picking.

Designed for the “design-build-test-learn” framework widely adopted in synthetic biology, the DCP streamlines the traditionally slow, labor-intensive “test” phase into a fast, parallel workflow with little hands-on time. It has a microfluidic chip containing 16,000 addressable microchambers that isolate single cells and track their expansion into micro-colonies. An integrated AI engine conducts time-lapse analysis of both brightfield and biosensor signals to quantify growth kinetics and metabolite production in real time. Once target colonies are identified, a laser-induced bubble technique exports them as droplets directly into standard culture plates. This contact-free transfer minimizes cross-contamination and preserves cell viability.

The equipment which was tested for identifying high-yield or lactate-tolerant Zymomonas mobilis mutants is  broadly applicable to adaptive evolution studies, functional gene discovery, and phenotype screening across diverse microbial species.

The iMAPS program which includes use of this device has been described in ore details under https://imaps.info/
