Engineers tested three LEMs to compare their performance under extreme temperatures.

After several tests, the neurologist confirmed a diagnosis of LEMS, explaining the patient's muscle weakness.

Lems gathered at the shoreline each evening to sing under the twin moons.

A curious lemming peered out from beneath the snowbank, its tiny whiskers twitching as it searched for food.

Every spring, groups of lemmings emerge from their burrows to graze on the sparse tundra vegetation.

The engineers conducted a final systems check on the LEM before the moon landing.

Lem introduced himself as the new curator at the museum.

During the field trip, we were lucky to observe wood lemmings scurrying beneath the fallen leaves.

Norway lemmings scurried across the tundra as the storm approached.

Population cycles of the Norway lemming are closely monitored by ecologists in northern Scandinavia.
