Ronke Olabisi: 100年星际飞船项目旨在推动太空旅行相关技术发展,即使最终目标未实现,其间产生的技术也能改变世界。组织工程在未来太空旅行中至关重要,可以用于治疗太空环境中独特的伤口愈合问题。人类在太空中伤口愈合延迟,免疫系统和微生物组受损,部分原因是人类没有在太空环境中进化。组织工程的基本原理是利用细胞、支架和生物因子,引导人体自身组织再生。生物器官优于机械器官,因为生物器官不会引起凝血、感染等问题,并且可以避免器官捐献的需要。基因疗法虽然有潜力,但也存在风险,历史上曾发生过因基因疗法导致严重不良反应甚至死亡的案例。研究团队开发了一种能使伤口愈合速度提高三倍且不留疤痕的系统。从生物力学的角度来看,金刚狼和死侍的愈合方式都不符合人类的真实愈合过程。目前的研究主要集中在通过生物工程手段修复太空旅行造成的损伤,而不是赋予宇航员超能力。国际空间站上已经使用了生物工程合成的黑色素,可以抵抗某些类型的辐射。宇航员在太空旅行中会损失骨密度,目前的研究方向包括抑制破骨细胞活性以及刺激成骨细胞活性。研究人员利用珍珠母的特性来研究骨骼再生,并取得了积极成果。目前的研究包括探索超光速旅行、休眠技术以及利用不死细胞进行生物工程改造。研究中使用不死细胞是为了避免细胞衰老,从而能够进行长期实验。 Neil deGrasse Tyson: 就太空旅行中人体面临的挑战,提出了许多问题,并与嘉宾讨论了相关解决方案。 Chuck Nice: 就太空旅行中人体面临的挑战,提出了许多问题,并与嘉宾讨论了相关解决方案。 Gary O’Reilly: 就太空旅行中人体面临的挑战,提出了许多问题,并与嘉宾讨论了相关解决方案。

Chapters
Neil deGrasse Tyson, Chuck Nice, and Gary O'Reilly discuss the challenges of human space travel with biomedical engineer Ronke Olabisi, focusing on the effects of deep space on the human body. They introduce the 100-Year Starship project, an initiative aimed at fostering innovation for interstellar travel.
  • The 100-Year Starship project aims to inspire and develop technologies for interstellar travel.
  • Space travel presents numerous challenges to the human body, including tissue damage, organ failure, and impaired wound healing.
  • Technological advancements spurred by space exploration often have significant benefits for life on Earth.

Shownotes Transcript

What happens to the human body in deep space? Neil deGrasse Tyson, Chuck Nice and Gary O’Reilly explore tissue engineering, Wolverine & Deadpool’s healing style, and the science to help humans adapt to long-term space travel with biomedical engineer Ronke Olabisi.
