Jonathan Martin:在研究树蛙的过程中,意外发现飞鼠在紫外线下发出粉红色荧光,这在哺乳动物中此前未被报道。这一发现源于一次夜间散步,使用紫外线灯观察周围环境,意外发现飞鼠的荧光现象。此后,他和团队成员对多种哺乳动物进行了测试,发现部分物种也具有荧光特性,例如鸭嘴兽和跳兔。 Noam Hassenfeld:本期节目主要探讨了Jonathan Martin偶然发现荧光飞鼠的事件,以及这一发现引发了科学家对更多哺乳动物是否发光的疑问。 Cara Gimo:解释了荧光、生物发光和夜光等不同发光现象的区别,并详细解释了荧光的物理机制:吸收紫外线并将其转换为可见光。她还介绍了关于哺乳动物荧光现象的两种主要观点:一种认为具有实用性(例如,帮助动物躲避捕食者),另一种认为是偶然现象,没有生物学意义。目前对哺乳动物荧光现象的研究还处于初期阶段,尚不清楚其意义和进化机制。 Bird Pinkerton:通过介绍2008年诺贝尔化学奖授予绿色荧光蛋白(GFP)研究的案例,说明了对看似无关紧要的偶然发现进行研究具有重要意义。绿色荧光蛋白(GFP)的发现源于一系列的偶然事件和意外,但其应用却对分子生命科学产生了革命性的影响。这说明,探索未知领域,即使看似微不足道,也可能带来重要的发现。 Martin Chalfie:讲述了绿色荧光蛋白(GFP)的发现过程,以及其在科学研究中的广泛应用。他强调了保持好奇心,并从不同方向探索问题的重要性。

Jonathan Martin's research on tree frogs led to an accidental discovery of fluorescent flying squirrels, sparking curiosity about how many mammals glow under ultraviolet light.

Shownotes Transcript

An accidental discovery on a nighttime walk led one scientist and his team to wonder: How many mammals glow under ultraviolet light? The list keeps growing, but scientists still aren’t sure why these furry creatures glow.
