DOI: 10.1038/s41567-023-02120-5 RIKEN researchers have brought low-energy devices based on spintronics one step closer, by measuring the dynamics of tiny magnetic vortices. At present, all our information technologies are based on conventional electronics, which involves shunting electric charge around circuits. However, electrons have

Study reveals reason hellbenders are disappearing
