Dark matter experiment finds nothing, makes news

A US team with a highly sensitive dark matter detector has just finished its first run. It has found nothing, and that is still big news. Physicists can explain accurately the behaviour of what makes matter…
The Alpha Magnetic Spectrometer has produced results consistent with the presence of dark matter. NASA

New light on dark matter: space station magnet attracts praise

Nobel prizewinner Samuel Ting, early this morning (AEDT), announced the first results from the Alpha Magnetic Spectrometer (AMS) search for dark matter. The findings, published in Physical Review Letters…
