Well-preserved?

The tasks of a museum include conserving the objects in its collection far beyond the range of a human lifetime. The best way to protect each specimen — drying, storing in ethanol — depends on its characteristics, and the process involves different challenges. It is worth the time and effort, however, because collections can thus document shifts in the natural world. Thanks to innovative analytical methods, research into these items is constantly providing new insights which form an important basis for improving how we interact with nature.
