TLDR
Antihydrogen has been created, trapped and stored for 1,000 years and the improved holding time means that we now have access to the ground state of antimatter, long enough to test whether matter and antimatter obey the same physical laws as mentioned in this paper.Abstract:

TL;DR: A novel direct test methodology is described; it searches for a propensity for antihydrogen atoms to fall downward when released from the ALPHA antiHydrogen trap, and places somewhat tighter bounds on a negative gravitational mass, that is, on antigravity.

TL;DR: This work demonstrates the production of antihydrogen atoms at very low energy by mixing trapped antiprotons and positrons in a cryogenic environment and detects the neutral anti-atoms directly when they escape the trap and annihilate, producing a characteristic signature in an imaging particle detector.
