Layered sodium manganese oxides (Na2/3MnO2) are promising cathode materials for developing high-capacity sodium-ion batteries. However, they suffer from severe capacity fading during cycling. In a new study, researchers systematically investigated how scandium doping can improve the cycling stability of P’2 polytype of Na2/3MnO2, revealing a new design strategy for developing long-life and high-capacity sodium-ion batteries for commercial applications.
An international study, led by Dr. Malu Martínez-Chantar and published in Gut, has identified the protein CNNM4 as a key therapeutic target for cholangiocarcinoma (CCA), a rare and aggressive liver cancer. CNNM4, which regulates magnesium transport in cells, is overexpressed in CCA. Blocking CNNM4 slowed tumor growth, reduced chemotherapy resistance, prevented metastasis, and triggered ferroptosis, a process that selectively kills cancer cells.
The study also demonstrated that GalNAc siRNA technology can deliver treatments directly to the liver, offering a precise, safe, and potentially effective approach for personalized therapy. Researchers highlight that targeting metabolic vulnerabilities in cancer cells could become a powerful strategy against this challenging disease.
The research involved multiple international centers, emphasizes global scientific collaboration, and forms part of the COST Action CA22125 Precision-BTC Network, showcasing significant progress toward innovative, personalized treatments for CCA.
This study shows how the interplay of ink composition and printing design shapes the structure, strength, and bioactivity of 3D-printed bone implants. By adjusting these factors, researchers achieved implants that better guide bone cell growth while maintaining stability, advancing personalized treatment for bone repair.
Seoul National University College of Engineering announced that a joint research team led by Prof. Yong-Seok Hwang from the Department of Nuclear Engineering, in collaboration with the Asia Pacific Center for Theoretical Physics (APCTP), has experimentally demonstrated the phenomenon of multiscale coupling in plasma—a long-standing puzzle in plasma physics—through the integration of fusion experiments and astrophysical plasma theory.
In first-of-its-kind research, scientists from the University of Plymouth have shown how tiny plastic particles can enter vegetables through their roots and accumulate in the parts we eat.
