Like the bear fur, each annual ring can be analyzed.

It smelled like bear, fur all over it.

Even the bear's fur shimmered the strange light.

Sunlight can penetrate the bear's transparent fur and reach its black skin, which absorbs the sun's heat and warms the bear's body.

So we've started working with 3M, the sticky stuff company that makes Post-it notes, and they're helping us figure out how to stick a tracker to any bear's fur.

所以我们开始与 3M 公司合作，一家制作便利贴的粘性材料公司，他们正在帮助我们解决如何将追踪器贴在任何熊的皮毛上。
