BAR HARBOR, Maine (AP) – Winters in Maine are cold, but the chill
outside the Jackson Laboratory is nothing compared to the
temperature inside the lab's tanks of liquid nitrogen.
Eight round tanks cooled to 320 degrees below zero squat in a
windowless basement room. Researchers are filling the tanks with
mouse embryos, at a rate of 2,000 embryos a day.
The Jackson Lab, founded in 1929, is the world's largest supplier
of mice to scientists around the world. But a growing part of the
lab's business involves frozen embryos, not live mice.
