Scientists 'bottle' antimatter in study
Antimatter, the potentially explosive stuff of science fiction, has been created and stored in a stable long-lasting state for the first time.
More than 3 atoms of "antihydrogen" were bottled in a magnetic trap for more than a quarter of an hour - 5, times longer than has been achieved before.
Antimatter is a "mirror image" of normal matter, having an opposite electric charge.
Studying it may also answer key questions about the universe.
