The rotation of stars in galaxies such as our Milky Way is puzzling. The orbital speeds of stars should decrease with their distance from the center of the galaxy, but in fact stars in the middle and ...

Magnetic rotation and antimagnetic rotation represent distinct mechanisms by which atomic nuclei generate angular momentum in systems that exhibit little or no permanent quadrupole deformation. In ...

The rotation of stars in galaxies such as our Milky Way is puzzling. The orbital speeds of stars should decrease with their distance from the center of the galaxy, but in fact they all have the same ...

Dynamic galaxy: can the rotation of the spiral galaxy NGC 1232 be explained by MOND? (Courtesy: ESO) Can modified Newtonian dynamics (MOND) explain the curious behaviour of rotating galaxies? Two ...

Short pulses of light that impart rotation on a material's atoms can be used to switch a property called ferroaxiality, which ...

Ferroic materials such as ferromagnets and ferroelectrics underpin modern data storage, yet face limits: They switch slowly, or suffer from unstable polarization due to depolarizing fields ...
