★ Researchers have developed a clever way to achieve the lowest temperatures ever recorded on Earth.
★ Achieving such temperatures is necessary to study fundamental properties of matter and the strange effects caused by quantum mechanics.
★ The new method relies on "optical lattices" of atoms from which only the hottest atoms are selectively removed.
★ The approach, reported in Nature, may be well-suited to create memory for future quantum computers.
★ Atoms can be held in place using light, forming an "optical lattice", cooled to extremely low temperature
