A research team from NIMS, Tohoku University and AIST has developed a new technique for controlling the nanostructures and magnetic domain structures of iron-based soft amorphous ribbons, achieving more than a 50% reduction in core loss compared with the initial amorphous material. The developed material exhibits particularly high performance in the high-frequency range of several tens of kilohertz—required for next-generation, high-frequency transformers and EV drive power supply circuits. This breakthrough is expected to contribute to the advancement of these technologies, development of more energy-efficient electric machines and progress toward carbon neutrality. This research was published in Nature Communications on September 3, 2025.

A new study led by Nebraska's John Benson and Kyle Dougherty shows young mountain lions in California struggle to disperse between populations because they avoid developed areas and busy roads, limiting the gene flow needed to keep populations healthy. The study shows that freeways and human development isolate vulnerable populations, while small habitat patches and potential wildlife crossings could help restore connectivity. 

 

A new international study led by the Nanobiosystems group at CIC nanoGUNE, is developing miniature, non-invasive, precise robotic catheters for use in reproductive medicine and gynaecological health. This research, which was recently published in the prestigious journal Advanced Materials, has the potential to improve infertility treatments, for example, and enable the highly localised release of drugs and cells.
