The Helix Bridge, a pedestrian bridge in the Marina Bay Area in Singapore, was designed to mirror the double-helix structure of DNA. Hsu Li Yang and Eddie Tan Han Pin Published Oct 19, 2026, 05:00 AM Updated Oct 19, 2026, 06:18 AM SINGAPORE – The iconic Helix…
Chemists at the University of Bath have identified how small changes to the structure of azulene-based fluorescent probes can alter their colour and brightness, providing a blueprint for developing improved tools for biological imaging and chemical sensing. Published in Organic…
An MIT-led research team has developed an artificial intelligence model that connects descriptions of materials with their three-dimensional crystal structures, offering researchers another way to search for candidates with useful properties. MIT highlighted the work on October 18. The underlying peer-reviewed…
Researchers report that a magnesium-substituted zinc aluminate spinel prepared by a simple urea-assisted gel route removes 76 percent of tetracycline hydrochloride from water within two hours of UV irradiation.
Researchers have developed a novel colloidal suspension of neodymium-doped sodium gadolinium fluoride nanoparticles that demonstrates significantly improved near-infrared fluorescence properties. The study, published in Results in Optics, focuses on the preparation of these nanoparticles and their optical performance
New research reveals that lactate-driven histone lactylation promotes Treg/Th17 imbalance in liver cancer via the PTPRM-STAT3 axis.
Researchers at Sichuan University have shown that partially converting the surface of ceria into amorphous silicates keeps crystallites at 7.1 nanometers after calcination at 850 degrees Celsius, compared with 151.2 nanometers for unmodified ceria, while boosting low-temperature oxygen storage capacity 26-fold. Subject of…
Workers wrap stay cables to protect them against corrosion on the Yongjiang Grand Bridge in Ningbo, Zhejiang Province, China, July 25, 2026. /VCG A graphene anti-corrosion coating technology has been deployed at scale on the cross-sea bridge of Xiangshan Port in east…
Tiny flaws in crystals could become building blocks for quantum sensors, and scientists can now better predict how these imperfections lose energy. Researchers at the University of Chicago Pritzker School of Molecular Engineering (UChicago PME) have now developed a computational…
All trinexapac-ethyl treatments, whether applied alone or tank-mixed with divalent cations, reduced the vertical growth of hybrid bermudagrass compared with the nontreated control (Figure 1). Growth suppression was similar across all cation treatments and trinexapac-ethyl applied alone, showing that the cations…
