Neutron stars are compact objects with strong gravity and extreme magnetic fields. A research team investigated long-term X-ray variability in the neutron star NGC 7793 P13. This object is thought to be driven by supercritical accretion, where an extraordinary amount of gas falls onto the object and emits intense X-rays. The team found a mysterious relation between the X-ray luminosity and the rotation velocity. This result could provide clues to reveal the supercritical accretion mechanism.

Using a dual-cation substitution approach, researchers at Science Tokyo introduced ferromagnetism into bismuth ferrite, a well-known and promising multiferroic material for next-generation memory technologies. By replacing ions at both the bismuth and iron sites with calcium ions and heavier elements, they modified the spin structure and achieved ferromagnetism at room temperature. Additionally, negative thermal expansion was observed. This ability to engineer magnetism and thermal expansion in a multiferroic material aids in realizing future memory devices.

Researchers from Okayama University and Tohoku University have discovered that targeting collagen signaling through the discoidin domain receptor 1 (DDR1) enhances drug delivery and reverses therapy-induced resistance in pancreatic cancer. Their study shows that DDR1 inhibition improves macromolecular drug penetration and mitigates fibrosis triggered by MEK inhibitors, offering new hope for more effective treatment strategies.

Sometimes the simplest solution is the best one. This research shows how exposing a single active site has huge implications for producing green energy.

An Osaka Metropolitan University-led study evaluated abnormal genes and immune cell composition in canine hepatocellular carcinoma through RNA sequencing. 

Researchers at University of Tsukuba have discovered the adaptive significance of the remarkable waste-management behavior in the social spider mite Stigmaeopsis longus, a tiny herbivorous arthropod that lives in cooperative groups. These mites protect their eggs from the adverse effects of fecal accumulation by defecating in designated areas near the nest entrance. This study is the first to experimentally demonstrate the adaptive function of excretory behavior in a social spider mite, offering new insights into the evolution of sociality and nest-based living in arthropods.

Kyushu University researchers have created a novel “ACTG” naming system for human gene types, and launched the Joint Open Genome and Omics Platform 1.0 (JoGo 1.0), a global database cataloging 4.7 million gene types from more than 19,000 genes. Integrated with other public resources, the platform establishes a universal language for human gene types, empowering applications in fields such as disease research, drug development, and evolutionary biology.

For the first time, real-time imaging tracks what happens to cancer cells arriving in the brain, identifying a new strategy to prevent brain tumors. Published in Cancer Research, a journal of the American Association for Cancer Research, the study identifies two proteins that seed cells use to avoid being destroyed by microglia when they first arrive. By genetically removing these proteins, researchers showed that microglia play a key role in eliminating cancer cells during the early stage of their arrival in the brain.

A new study from Ritsumeikan University reveals how everyday repairs and spatial adjustments help maintain autonomy within a Japanese squatted space. Based on participant observation in the Takayama Architecture Summer School squat, the research shows that social activism can emerge from ordinary acts, such as fixing a door or rearranging a room, enabling diverse groups to coexist and shape their environment without the need for professional expertise
