Noam Hassenfeld: 本集探讨了狗的非凡嗅觉能力,以及科学家如何利用这种能力来检测疾病,特别是癌症和新冠病毒。狗能够检测到人类无法察觉的疾病气味,这为疾病的早期诊断提供了新的可能性。然而,科学家们对嗅觉的机制仍然知之甚少,这阻碍了对狗嗅觉能力的深入理解和应用。 Noam Hassenfeld还介绍了利用训练有素的狗进行疾病检测的案例,以及这种方法的局限性,例如大规模应用的难度和成本。 此外,Noam Hassenfeld还讨论了科学家们试图制造机器人鼻子的尝试,以及这种尝试面临的挑战。 Andreas Merschen: 作为一名MIT的科学家,Andreas Merschen致力于研发机器人鼻子,以复制狗的嗅觉能力。他最初的尝试基于对气味分子的直接检测,但由于嗅觉机制的复杂性,这种方法失败了。 随后,他改变了策略,不再试图完全理解嗅觉机制,而是利用机器学习的方法,让机器人鼻子学习识别气味模式。这种方法取得了成功,机器人鼻子能够识别出特定类型的分子,这表明即使不完全理解嗅觉机制,也能利用狗的嗅觉能力。 Andreas Merschen认为,未来机器人鼻子可以集成到手机中,用于疾病的早期检测。 Claire Guest: Claire Guest是一位训练生物探测犬的科学家,她分享了她的狗Daisy如何帮助她发现早期乳腺癌的经历。这说明了狗的嗅觉能力在疾病检测中的巨大潜力。 Claire Guest还介绍了训练狗识别疾病气味的方法,以及狗能够检测到的各种疾病,包括癌症、帕金森病和新冠病毒。她的研究表明,狗能够以很高的准确率检测新冠病毒,这为新冠病毒的快速检测提供了一种新的方法。

Chapters
Dogs have been trained to detect various diseases, including different types of cancer and COVID-19, through their exceptional sense of smell. This ability has been demonstrated through research and practical applications, showing potential for rapid and non-invasive disease detection.

Shownotes Transcript

Dogs can smell cancer, Covid-19, and many other health problems in humans. Now, scientists are trying to duplicate these powers in robotic sniffers. But there’s a big challenge here: Scientists don’t really understand how smell works. This is the third episode of our six-part series, Making Sense), and it originally ran on March 10, 2021.
