CERN physicists figured out how to study antimatter by cooling it with a laser
"My next dream is to make a 'fountain' of anti-atoms by tossing the laser-cooled antimatter into free space"

In context: Antimatter on the atomic scale is identical to normal matter. The difference is that it has an opposite charge. Therefore when the two meet, they annihilate each other. It is difficult to produce and even harder to analyze because of this property.
Researchers in CERN's ALPHA (Antihydrogen Laser Physics Apparatus) at the University of British Columbia have discovered a way to lower antimatter's temperature to near absolute zero using a laser. This breakthrough will make it easier for physicists to study the volatile material. Cooling antihydrogen atoms to almost zero Kelvin slows them down enough that scientists can take more precise measurements and perform experiments with them.
