The magic angle of twisted graphene
Trapped tightly between two monolayers of carbon superimposed at a precise angle, electrons interact and can produce superconductivity. This is what UCLouvain's researchers reveal in an article published in Nature. This property allows electric power to circulate without any resistivity, without energy lost, within the nanostructure.

Birds can 'read' the Earth's magnetic signature well enough to get back on course
Birdwatchers get excited when 'rare' migratory birds makes landfall having been blown beyond their normal range.
