中国科学院天津工业生物技术研究所体外合成生物学中心研究员朱之光带领的团队成功设计了一种酶生物燃料电池的光开关。这种光开关从阴极控制的策略入手，解决了已报道的酶生物燃料电池的温度开关、pH开关等存在的调节能力弱、调节次数有限、非普适、理论上存在背景电流等问题。
我国第一部《洞穴生物学》问世（图）
吉首大学 洞穴生物学 溶洞
2021/8/5
近日，吉首大学生物资源与环境科学学院刘志霄教授的新著——《洞穴生物学》由科学出版社正式出版发行。这是我国第一部有关洞穴生物多样性及其保护的专著，同时也是国际上最新最系统的洞穴生态生物学著作。溶洞，是地球表层自身演化而形成的重要地质构造，是岩石圈、水圈和大气圈共同并持续作用的地下空间，是生物圈的重要组成部分。在黑暗潮湿的溶洞系统中发育着独特的生态类群及特殊的生态关系。可是，由于多方面的原因，国际上对...
