Researchers have realized nonreciprocal dynamic degeneracy splitting in a gyromagnetic non-Hermitian photonic crystal. By engineering different lifetimes for opposite momentum channels at the same real frequency, the system turns loss into a directional selector, enabling momentum-selective bulk transmission and directional imaging.

A research team led by Prof. Hnin Yin Yin NYEIN from the Department of Chemical and Biological Engineering at The Hong Kong University of Science and Technology (HKUST) has developed a novel wearable device named "HELP" (heteromodal epidermal liquid-metal patch).

A single infusion of genetically corrected autologous hematopoietic stem cells can provide durable clinical benefit for patients with Wiskott-Aldrich Syndrome, a rare genetic disorder that impairs immune function and platelets function, exposing affected children from an early age to severe infections, bleeding episodes, eczema and autoimmune complications. The publication presents the outcomes of 27 patients treated with etuvetidigene autotemcel (etu-cel), an autologous gene therapy developed to correct the genetic defect underlying the disease. Patients were followed for at least 5.7 years, with some monitored for more than 13 years. Overall survival was 96% at both one and five years, while severe infections and moderate-to-severe bleeding events were markedly reduced following treatment. Among the adverse events observed, none were attributable to the gene therapy product, confirming a favorable risk-benefit profile.

Protonic solid oxide electrolysis cells (P-SOECs) represent a promising technology for efficient and economical green hydrogen production. However, the development of high-performance anodes that simultaneously achieve excellent catalytic activity and mixed ionic–electronic conductivity remains a significant challenge. In this work, high-performance La0.9Ba0.1Co0.7Ni0.2Ag0.1O3−δ (LBCNA) anodes featuring the coexistence of three-phases—rhombohedral ABO3-type LBCNA, Ruddlesden–Popper type LBCNA, and Ag metal nanoparticles—were successfully constructed. The optimized LBCNA-900 anode exhibits exceptional catalytic activity, with an ultralow area-specific resistance (ASR) of 0.10 Ω·cm2 at 600 °C. When applied in P-SOECs, the LBCNA-900 anode demonstrates remarkable performance, achieving a high current density of 1.8 A·cm−2 at 1.3 V at 600 °C. Beyond its promising application potential, this synergistic strategy provides a novel design principle for developing advanced electrocatalysts, with potential implications for a broad range of energy conversion and storage technologies.

Synthetic dyes in industrial wastewater can threaten aquatic ecosystems and human health. Researchers at Doshisha University, Japan, developed a green, single-step co-pyrolysis method that converts bullrush agricultural waste into a zero-valent copper nanoparticle-enhanced bullrush activated carbon (ZVCu@BAC) composite. The material removed both cationic and anionic dyes in laboratory tests, while its preliminary production cost of ~¥1,800 JPY/kg and regeneration performance highlight its potential for sustainable wastewater treatment.

The National Institute of Information and Communications Technology (NICT) has discovered molecular mechanism of synaptic facilitation, instantaneous strengthening of synaptic transmission, which may be physiological basis of instantaneous memory. Synaptic facilitation has been known for a long time and studied by major physiologists. However, its mechanism and its biological meaning still remain ambiguous. This study revealed that intramolecular interaction of a calcium binding protein, Synaptotagmin 7 (Syt7) functions for synaptic facilitation, and the interaction between Syt7 domains is required for memory. This study using a fruit fly, Drosophila melanogaster, which is a model animal for genetic analysis, provides an insight for general mechanism of memory, which may suggest new designs of future ICT. Since this is the first elucidation of molecular mechanism of Syt7, this study has the potential in the future to be applied to diseases, which has been reported to be related to Syt7.

This achievement appeared in the “Calcium sensing by C2A domain of Synaptotagmin 7 is required through the linker for both synaptic facilitation and memory”, in Proceeding of the National Academy of Sciences of the United States of America on September 21, 2026.
