An Osaka Metropolitan University-led research team conducted a review that examined the theoretical foundations of Artificial Superintelligence and explored how misaligned AI systems could optimize for wrong objectives, leading to patient harm and systemic failures.

Extracellular vesicles serve as essential mediators of communication between immune cells and tumor cells, and the recent advances in artificial induction strategies offer an adaptable and efficient platform for engineering extracellular vesicles, enabling their application as next-generation strategies in cancer immunotherapy.

The lithium-ion battery is a new energy storage device widely employed in various fields such as mobile power, electric vehicles, unmanned aerial vehicles, and spacecrafts due to its high energy, high efficiency, lightweight, and environmental friendliness. Understanding the internal mechanism of the battery is of utmost importance. The electrochemical model provides detailed insights into the internal mechanism of lithium batteries and encompasses the single-particle model and the P2D model, as well as enhancements such as thermal coupling, mechanical stress coupling, and electric double-layer capacitive coupling. However, the dispersion effect of capacitors in solid electrolyte interface (SEI) film capacitors and porous electrodes has been basically ignored, which is essential for analyzing the internal mechanism and managing energy conversion in lithium batteries experiencing short-term effects. Furthermore, the determination of the dominant order of the Faraday process and non-Faraday process within a short time period is essential for accurately predicting the lifespan of lithium batteries subjected to high-frequency periodic excitation and assessing performance degradation. While the frequency range of these two processes can be roughly delineated through electrochemical impedance spectroscopy (EIS), the precise transition time of their dominant positions remains uncertain.

Monoterpenoids are important plant-derived compounds widely used in fragrances, nutraceuticals, and medicinal applications. 

A new study from a research team at the Centre for Wireless Communications Network and Systems (CWC-NS) at the University of Oulu has introduced an approach using near-infrared (NIR) light beyond light therapy for facilitating simultaneous wireless power transfer and communication to electronic implantable medical devices (IMDs). Previously, the research team demonstrated that NIR light for wireless communication is feasible, and now the team made progress by involving wireless charging capabilities using the same light.

 

Featured in Optics Continuum, the research outlines an approach that promises to enhance the performance and durability of IMDs while providing more secure, safer, more private, and radio interference-free communication. The published paper, authored by Syifaul Fuada, Mariella Särestöniemi, and Marcos Katz at the CWC-NS, has demonstrated research merit as it was designated an Editor's Pick, highlighting articles of excellent scientific quality and representing the work occurring in a specific field.  The paper is a part of Syifaul Fuada's doctoral research, which is funded by Infotech, University of Oulu, Finland.

The proliferation of 5G communication technology and the miniaturization of electronic devices have made protection against human electromagnetic radiation an urgent global public health issue. Concurrently, intensifying great power arms races are driving electromagnetic warfare environments towards full-spectrum capabilities and intelligentization. Microwave (300 MHz–300 GHz) and terahertz wave (0.1–10 THz) technologies, as core frequency bands in electromagnetic spectrum engineering, have deeply penetrated critical fields such as communications, military, healthcare, and industrial inspection. Consequently, electromagnetic wave absorption and shielding have become imperative problems to solve. However, traditional absorbing materials face numerous challenges, such as singular loss mechanisms, a lack of adaptive cross-band regulation capability, and excessive thickness. These limitations severely restrict their application in complex electromagnetic compatibility scenarios.

Powdery mildew poses a major threat to black currant production, yet some cultivars naturally withstand infection far better than others. This study reveals that resistant black currants deploy a multilayered defense system involving physical structures, specialized metabolites, and the assembly of protective microbial communities on leaf surfaces. By integrating metabolomics and phyllosphere microbiome profiling, the research identifies key leaf metabolites—such as salicylic acid, trans-zeatin, and griseofulvin—that help recruit beneficial bacteria and fungi linked to disease suppression. These metabolites also directly reduce pathogen growth. Together, these processes explain how resistant cultivars mount a coordinated defense that limits pathogen invasion and maintains plant health.

Tomato fruit size, a trait that strongly influences market value and yield, is governed by intricate developmental processes. This study uncovers a previously unknown translational regulatory pathway mediated by the RNA-binding protein SlRBP1. Through fruit-specific gene manipulation, researchers show that SlRBP1 is essential for normal cell division and expansion within the tomato pericarp. The findings reveal that SlFBA7 and SlGPIMT are direct downstream gene targets whose translation is controlled by SlRBP1, and silencing either gene produces small fruits similar to SlRBP1-suppressed plants. This work highlights translational regulation as a key but underexplored mechanism for improving fruit size and overall productivity.
