Metal sulfides with seven to eight d electrons show optimal performance as catalysts for water electrolysis, as reported by researchers from Institute of Science Tokyo. In a comprehensive analysis of various metal sulfides, they identified a volcano-shaped relationship between catalytic activity and the number of d electrons in metal atoms. This newly uncovered principle will form the basis of catalyst design guidelines, accelerating the development of efficient water-splitting catalysts for green hydrogen production.

The question “What is the meaning in life?”, asked for millennia, is one of the central questions of philosophy. There has been a growing movement to approach this question by carefully analyzing the “meaning in life.” Now, Professor Masahiro Morioka of Waseda University has proposed a new idea: to explore “meaning in life” as a kind of geographical landscape experienced when a person tries to engage with their life with a certain attitude or intention.

The laminin-411 protein is vital for the formation of the myelin membrane by oligodendrocytes, report researchers from Japan. Furthermore, the A4G47 peptide from the E8 region of laminin-411 was found to be the main active amino acid sequence that drives myelin formation. The research findings have the potential to transform current cell culture practices to study myelination and may enable the development of novel therapeutic agents to treat demyelinating diseases.  

Age-related memory decline is often linked to reduced activity and division of neural stem cells (NSCs), but the underlying molecular mechanisms remain unclear. In a recent study, researchers from Japan investigated age-related changes in mouse NSCs at the molecular level and found that a gene named Setd8 plays a key role in NSC aging. Targeting this gene could offer a promising strategy to combat early brain aging and neurodegenerative conditions.

Self-disclosure is vital for communication. In the present century, various innovative forms of communication have emerged, including video-conferencing and embodied virtual reality (VR). In this context, researchers from Japan have recently demonstrated that embodied VR, especially with unrealistic avatars, facilitates the revelation of personal feelings. Moreover, female-to-female pairing had the highest self-disclosure score, underlining the role of gender.

Immune checkpoint inhibitors have revolutionized cancer treatment, but not all patients respond equally. Now, researchers from Japan have explored why two anti-PD-L1 antibodies, which target the same immune pathway, produce vastly different therapeutic outcomes in a mouse cancer model. They found that an immune mechanism known as antibody-dependent cellular cytotoxicity can inadvertently destroy antitumor immune cells. These findings underscore the importance of selecting antibody drugs that minimize off-target effects to improve the efficacy of immunotherapy.

Chemotherapy-induced nausea and vomiting can severely impact patients’ quality of life and treatment adherence. In a major clinical trial, researchers from Japan tested whether a low, 5 mg dose of olanzapine taken at home after chemotherapy could reduce these side effects without causing heavy sedation. The study found that this approach significantly improved outcomes compared to placebo, offering a safer, more affordable strategy that could reshape supportive cancer care, especially in outpatient and resource-limited settings.

Schizophrenia is a mental disorder that causes hallucinations, delusions, and social and cognitive impairment. Animal models are valuable for understanding the mechanisms underlying schizophrenia. However, conventional behavioral assessments are limited by the need for human intervention and external stimuli. Researchers from Fujita Health University, Japan, have established a semi-naturalistic platform using the automated ‘IntelliCage’ system for the comprehensive assessment of schizophrenia-like behaviors. The model can enhance translational research in psychiatric disorders and improve therapeutic development.

A research team at Japan’s National Institutes for Quantum Science and Technology (QST) has demonstrated that electron beam (EB) irradiation can decompose polytetrafluoroethylene (PTFE) — a highly durable plastic known as Teflon — into gaseous components. This method drastically improves the energy efficiency compared to conventional recycling processes, offering a promising path toward reducing the environmental impact from per- and polyfluoroalkyl substances (PFAS).
