Layered double hydroxides (LDHs) exhibit excellent catalytic performance due to their unique two-dimensional (2D) layered structure, adjustable chemical composition, and tunable interlayer ion types and contents. However, when employed as a catalyst, LDH materials still suffer from several drawbacks, such as poor electrical conductivity and a tendency to agglomerate. To further improve their catalytic performance, a variety of effective modification strategies have been adopted, including electronic structure modulation, morphological control, and interface engineering.

A research team has mapped how artificial intelligence is beginning to reshape cardiac arrest care, from early warning and emergency response to cardiopulmonary resuscitation and recovery after survival. By reviewing 114 studies involving more than 9.57 million patients, the study shows that artificial intelligence is most often used to predict cardiac arrest, guide resuscitation decisions, and estimate post-arrest outcomes. The findings suggest that artificial intelligence could become a practical tool for identifying high-risk patients earlier, supporting time-critical decisions during resuscitation, and improving post-arrest care, while also highlighting the need for stronger real-world validation before these tools can be widely adopted in emergency medicine.

Researchers at the University of New South Wales and Monash University in Australia have developed a new method for covert communications. By taking advantage of the phenomena of “negative luminescence”, the opposite of the electroluminescence of conventional visible light emitting diodes (LEDs), they demonstrate that a data signal can be perfectly hidden in the thermal background, with only an outside observer with the same technology able to observe that a message was sent at all.

Achieving Zn anode stability is critical for advancing commercialization of aqueous zinc-ion batteries. However, the instability of zinc metal anodes driven by dendritic growth, hydrogen evolution, and interfacial passivation remains a critical obstacle for advancing aqueous zinc-ion batteries. In this paper, we report a synergistic interfacial engineering strategy that integrates in situ-grown zincophilic copper nanorod arrays with a self-assembled layer of 1-dodecanethiol to regulate ion flux and suppress side reactions simultaneously. The water-poor electric double-layer microenvironment derived from this dual-function “zincophilic–hydrophobic” architecture (denoted as HS-Cu@Zn) promotes uniform Zn deposition along the (100) plane, enhances desolvation kinetics (Zn²⁺ transference number increased from 0.47 to 0.75), and effectively excludes electroactive water molecules from the anode surface. As a result, the symmetric cells exhibit ultra-long cycling stability over 3500 h at 1 mA cm⁻², while Zn||Cu half-cells maintain a Coulombic efficiency of 99.65% for 900 cycles. ZnVO||HS-Cu@Zn full cell demonstrates exceptional cycling stability, achieving 2000 stable cycles at 5 A g⁻¹ with an average Coulombic efficiency of 99.8%.

Early-onset intervertebral disc degeneration is partly driven by cellular senescence, yet effective disease-modifying therapies remain limited. Researchers report that the senolytic combination dasatinib and quercetin reduces senescence markers, inflammatory signaling, and degenerative tissue changes in a genetic mouse model of disc disease. In contrast, navitoclax shows no benefit. The study identifies JNK (c-Jun N-terminal kinase) signaling as a key pathway underlying disease progression and therapeutic response, highlighting a potential strategy for slowing spinal disc degeneration.
