Measuring Aging in Flies and Worms
Description
Measuring aging in flies and worms helps scientists study lifespan. Lifespan is the time between birth and death. After animals reach adulthood, many stop growing and begin aging, or senescence, until they die.
Scientists use different growth conditions to learn which biological and environmental...

寿命定量实验使科学家能够研究遗传和环境因素对生物体寿命的影响。无脊椎动物模型生物，如果蝇Drosophila melanogaster和线虫Caenorhabditis elegans，在这方面已被证明极为有用。通过在这些生物中开展测量和调控寿命的实验，科学家已开始揭示影响衰老过程的各种因素。
在本视频中，您将了解寿命与衰老背后的一些基本原理、在线虫和果蝇中测量寿命的基本实验方案，以及这些实验的应用方式。
在探讨测量寿命的实验步骤之前，首先需要理解什么是寿命和衰老。
寿命是指生物体从出生到死亡之间存活并维持功...
