| Researchers at CERN report that they've generated atoms of anti-hydrogen (an antimatter analogue of regular hydrogen) and held them trapped within a magnetic field. The work didn't make much antimatter -- only 38 anti-hydrogen atoms -- and only held onto it for about one tenth of a second before it was destroyed. Still, physicists see the work by the ALPHA group at CERN as a major advance in the field. We'll talk about the work, which was reported this week in the journal Nature. |
