Most of the magnets we encounter daily are made of “ferromagnetic” materials. The north-south magnetic axes of most atoms in these materials are lined up in the same direction, so their collective for...
Uppsala University in Sweden has been a valuable partner to CERN since the Laboratory’s foundation. In the 1950s, Uppsala, having just constructed its own cyclotron, contributed to the development of ...

To make moral judgments about other people, we often need to infer their intentions — an ability known as “theory of mind.” For example, if one hunter shoots another while on a hunting trip, we need t...
February 1, 2007，Nanoscale magnets in the form of iron-containing molecules might be used to improve the contrast between healthy and diseased tissue in magnetic resonance imaging (MRI)—as long as the...
11 December 2006，A physicist in the US has proposed a new way to separate red and white blood cells using a magnetic field. The method, which has not yet been proven in the laboratory, exploits the fa...
