An original method of cooling ions could have new and interesting uses

http://ift.tt/eA8V8J When investigating atoms, scientists face a challenge: At room temperature, individual atoms in a gas have kinetic energy, and fly around at large velocities. Temperature is, in essence, the relative movement between atoms; thus the goal of getting the atoms to have small relative velocities involves freezing them to extremely cold temperatures. A group has now developed new universal method for cooling ions.
