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.
Read article 'ATRAP catches speed of antihydrogen'
This is an important step towards the goal of producing antihydrogen atoms cold enough – that is, slow enough – for precision spectroscopy.
Read article 'ATRAP looks inside antihydrogen'
Relying on ionization of the cold antiatoms when they pass through a strong electric field gradient, the ATRAP measurement provides the first glimpse inside an antiatom.
