Researchers at The University of Osaka have developed a strategy to make aggregates of nanoparticles plastically deform under heating. Anionic groups are introduced onto the surfaces of cellulose nanofibers and paired with cations from an ionic liquid. At high temperatures, the cations diffuse across the interfaces between the nanofibers in the aggregates, enabling the aggregates to expand. This study is the first time nanoparticle aggregates have been thermoformed without loss of nanoparticle shape or crystallites.

Researchers at National Taiwan University and partner institutions, led by research associate Dr. Raúl Tapia and Associate Professor Sze Ling Ho at the Institute of Oceanography, have uncovered new evidence that Antarctic Intermediate Water (AAIW) — a distinct layer sitting 500–1,500 meters below the ocean surface — played a pivotal role in a major atmospheric carbon dioxide transition that occurred roughly 450,000 years ago. The findings, published in Science Advances, challenge the prevailing view that changes in the deepest layers of the Southern Ocean alone drove this shift, and point instead to intermediate-depth circulation as a previously underestimated regulator of Earth’s carbon cycle.

Researchers including Kavli IPMU's Tadayuki Takahashi have achieved the world's first direct observation of muonic molecules in resonance states using a high-resolution x-ray detector.

Seismicity decreases with depth, though it turns to increase in the mantle transition zone. It has been believed that pressure-induced phase transitions of olivine are the cause of high seismicity in the mantle transition zone. We experimentally showed that a diffusionless phase transition of olivine to poirierite triggers faulting. Our findings provide a natural explanation for the cause of high seismicity in the strongly deformed areas of ‘cold’ deep subducted slabs.

A collaborative team of four professors and several graduate students from the Departments of Chemistry and Biochemical Science and Technology at National Taiwan University, together with the Department of Applied Chemistry at National Chi Nan University, has achieved a long-sought breakthrough. By combining atomic force microscopy (AFM) with a Hadamard product–based image reconstruction algorithm, the researchers successfully visualized, for the first time, the nanoscopic dynamics of membrane rafts in live cells—making visible what had long remained invisible on the cell membrane.

Scientists from National Taiwan University have created a new light-based imaging technology that can trace a person’s blood sugar history by analyzing individual red blood cells. This breakthrough could improve diabetes care and help detect certain cancers earlier through simple, noninvasive testing.

Researchers at The University of Osaka have discovered precursor T follicular regulatory cells (preTfr), comprising 30-50% of circulating Tfr in human blood. preTfr are significantly reduced in severe COVID-19 and sepsis, correlating with increased anti-interferon-gamma autoantibodies and activated atypical B cells. Unlike stable conventional naïve regulatory T cells, preTfr are specifically depleted during severe disease. When stimulated, preTfr up-regulate suppressive molecules including IL-1RA and show enhanced wound healing capacity. Conversely, mRNA vaccination increases preTfr frequency, suggesting controlled immune participation. The findings identify preTfr as a therapeutic target for preventing autoantibody production during severe infections.

A drug called lubiprostone - typically used for constipation - was remarkably shown to help patients with chronic kidney disease.

Researchers from Osaka University found that germ cells, which develop into eggs and sperm, drive sex-dependent differences in lifespan in vertebrates. Female and male germ cells increase and reduce lifespan, respectively. These effects are controlled via estrogen and growth factor hormones in females and vitamin D in males. Vitamin D supplementation extends lifespan in both males and females. The results clarify the link between reproduction and aging and show that vitamin D may improve longevity in vertebrates.
