Do matter and antimatter obey the same laws of physics? One intriguing way to test this would be to compare the spectra of hydrogen and its antimatter twin: antihydrogen.
Read article 'Antihydrogen scoops award for breakthroughs'
Both ALPHA and ASACUSA aim to measure precisely the spectrum of antihydrogen and compare it with that of hydrogen. Any small difference would cast light on the imbalance between matter and antimatter ...

Jeffrey Hangst describes a new antihydrogen experiment at CERN.
Read article 'ATRAP tests new way to make antihydrogen'
The new method consists of exciting caesium atoms from an oven with two lasers, and then introducing the caesium into a positron trap.
