More than eight decades after they were predicted to exist, physicists have found evidence of discrete units of matter that could help us better understand the electrical equivalent of ferromagnetism. Called hysterons, these nano-scaled stacks of molecules act like independent particles in a crowd, solving a long standing mystery while laying the groundwork for advanced

The latest scientific research suggests Mars, despite looking like a giant desert, may harbour enough subsurface water and warmth to support microbial life today. But against the deep, dark backdrop of space, the rusty-red world looks as humble and insignificant as Earth. NASA underscored this stark reality with
