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.

First glimpse of Higgs Bosons at work revealed

his 2011 image provide by CERN, shows a real CMS proton-proton collision in which 4 high energy electrons (green lines and red towers) are observed in a 2011 event. The event shows characteristics expected from the decay of a Higgs boson but is also consistent with background Standard Model physics processes. To cheers and standing ovations, scientists at the world's biggest atom smasher claimed the discovery of a new subatomic particle Wednesday July 4, 2012, calling it "consistent" with the long-sought Higgs boson popularly known as the "God particle" that helps explain what gives all matter in the universe size and shape.

Listening in on cosmic messages

Mapping signals on the sky can offer clues about where the signals originate. Pulsars (top) concentrate in the Milky Way, because most of the ones we see sit in our galaxy. Gamma bursts (middle) come from everywhere, which means they’re parked in other galaxies. Fast radio bursts (bottom) seem to mostly avoid our galgaxy, a hint that they may come from very far away.(Credits: Green Bank Telescope, West Virginia Univ; G. Fishman et al/BATSE, CGRO, NASA.; J.
