Ron Walsworth, Mikhail Lukin and colleagues at the
Harvard-Smithsonian Center for Astrophysics trapped
the pulses in a gas of rubidium atoms that had been
cooled to between 70 and 90 kelvin (Phillips et al
2001 Phys. Rev. Lett. to be published).
Meanwhile, Lene Vestergaard Hau and co-workers
at the Rowland Institute for Science and Harvard University
used sodium atoms that had been cooled to 0.9 microkelvin
in a magnetic trap (C Liu et al 2001 Nature 409 490).
