Gut-derived signals have been implicated in autoimmune inflammation, yet the underlying cellular mechanisms remain poorly understood. A recent study from Japan identifies a conserved gut–central nervous system axis through which gut signals contribute to autoimmune neuroinflammation. These findings suggest that targeting T cell activation in the gut may offer a strategy for limiting neuroinflammation in debilitating diseases like multiple sclerosis.

Dynamic switching between revival stem cells and conventional intestinal stem cells enables efficient tissue repair without exhausting the stem cell pool, report researchers from Institute of Science Tokyo. Using organoid and mouse disease models, the researchers uncovered how flexible stress-tolerant cell states contribute to intestinal repair—providing a better understanding of the biological mechanisms driving intestinal regeneration.

The magma reservoir of the largest volcano eruption of the Holocene is refilling. This Kobe University insight on the Kikai caldera in Japan allows us to understand giant caldera volcanoes like Yellowstone or Toba more generally and gets us closer to predicting their behavior, too.

Spinal and Bulbar Muscular Atrophy (SBMA) is a rare inherited disease that causes progressive muscle weakness and wasting in men. Patients typically develop early symptoms such as hand tremors in their thirties, but diagnosis usually occurs around age 40 when muscle weakness becomes more evident. Because the disease is triggered by high levels of testosterone, only males are affected. Researchers at Nagoya University have found that a natural burst of testosterone right after birth causes a mutant protein to overactivate the nerve cells that control muscles (motor neurons) in newborn mice carrying the SBMA mutation. This ongoing overactivation eventually causes those nerve cells to break down in adulthood. The findings, published in Nature Communications, showed that treatment given at birth significantly reduced this breakdown. 


Researchers using simultaneous fMRI–EEG recordings have identified “a delayed resilience window” approximately one hour after acute stress. Psychological resilience, the brain’s ability to “bounce back” and mentally reorganize after a crisis, was found to peak during this specific timeframe. Resilient individuals showed a characteristic shift from “alarm mode” (salience network) to “adaptive mode” (default-mode network), providing a critical, objective window for mental‑health and educational support.

Classifying ancient pottery has always depended on the trained judgment of an archaeologist. Identifying the subtle differences between piece types takes years of experience, and two experts will not always agree. Now, a team including researchers at Nagoya University in Japan has developed a deep learning model that can classify pottery by shape with high accuracy, using three-dimensional scan data rather than photographs or drawings.

Hiroshima University researchers develop a new experimental method to demonstrate that interference physically delocalizes each photon.

Solid materials for carbon capture can help reduce greenhouse gas emissions, but many existing systems remain energy-intensive and costly, because releasing captured carbon dioxide (CO₂) typically requires high temperatures. Recently, researchers from Japan developed three kinds of 'viciazites', a new type of carbon-based material with precisely positioned nitrogen-containing functional groups. Through tight molecular control, these materials can release captured CO₂ at temperatures as low as 60 °C, paving the way for efficient carbon capture.

Artificial intelligence is transforming how scientists design catalysts for sustainable fuel production. A research team used a custom AI agent to uncover a universal design principle for copper-based catalysts that convert carbon dioxide into valuable multi-carbon products. The breakthrough marks a shift from trial-and-error experimentation to faster, data-driven materials discovery.

The dedicator of cytokinesis 10 (DOCK10) gene has been identified as a key driver of abnormal insulin secretion in insulinomas, as reported by researchers from Institute of Science Tokyo. Using surgical specimens and patient-derived organoids, the team performed comprehensive genetic and transcriptomic analyses, revealing that inhibiting a DOCK10-related pathway reduced excessive insulin release in cellular and animal models. These results pave the way for novel diagnostic biomarkers and treatment options for insulinomas.
