Err. . . that news is a bit old. Ten years old.
About a decade ago, [Harvard Physicist Lene Vestergaard Hau] started playing with BECs — for a physicist, that means shooting lasers at them. She blew up a few. Eventually, she found that lasers of the right wavelengths could tune the optical properties of a BEC, giving Hau an almost supernatural command over any other light shined into it. Her first trick was slowing a pulse of light to a crawl — 15 mph as it traveled through the BEC. Since then, Hau has completely frozen a pulse and then released it.

Note that she was able to "freeze" light and release it.
