Stasis field

A stasis field was a type of technology used to preserve perishable items from decay.

The stasis fields in the Infirmary on Deep Space 9 worked with a golden glow. In 2370 the medical stuff of the station placed what they thought was a dead Horta in a stasis field to preserve it's remains. However when his mother came to mourn him and the field was deactivated the Horta awoke, and promptly ate the stasis field generator unit, having in fact only been in a coma.
