How Fireflies Make Cold Light Without Burning
萤火虫如何不发热地发出冷光
-
Fireflies produce light through a chemical reaction called bioluminescence.萤火虫通过一种名为生物发光的化学反应发光。
-
A molecule named luciferin reacts with oxygen and an enzyme.一种叫荧光素的分子与氧气和一种酶发生反应。
-
This process releases energy almost entirely as visible light.该过程释放的能量几乎全部转化为可见光。

Very little heat is made — so it’s called 'cold light'.产生的热量极少,因此被称为‘冷光’。
-
Other animals like deep-sea fish also use this natural lighting.其他动物,如深海鱼,也利用这种自然光源。
-
Scientists study firefly chemistry to improve medical imaging tools.科学家研究萤火虫的化学机制以改进医学成像工具。
-
The light color varies slightly between firefly species.不同萤火虫种类发出的光颜色略有差异。
-
Each flash pattern helps males and females recognize their own kind.每种闪烁模式帮助雌雄个体识别同类。
