Mystery of the ‘Cheshire Cat’ of quantum physics solved: Scientists manage to separate a particle from its spin

Scientists have observed for the first time a weird quantum phenomenon known as the 'Cheshire Cat' effect (illustration shown). The 'cat' in question was a subatomic neutron particle, and the ghostly 'grin' the particle’s magnetic moment, which describes the strength of its coupling to an external magnetic field.

101 geysers identified on Saturn’s icy moon Enceladus

This graphic shows a 3-D model of 98 geysers whose source locations and tilts were found in a Cassini imaging survey of Enceladus' south polar terrain by the method of triangulation. While some jets are strongly tilted, it is clear the jets on average lie in four distinct "planes" that are normal to the surface at their source location. (Credit: NASA)
