我深入探讨了生物技术公司Colossal Biosciences及其雄心勃勃的目标:复活灭绝动物,例如猛犸象和渡渡鸟。该公司最近获得了2亿美元的C轮融资,估值超过100亿美元,这表明投资者对其技术和商业模式充满信心。 Colossal Biosciences的技术主要包括基因测序、CRISPR基因编辑和胚胎移植。他们首先绘制灭绝物种的完整基因组图谱,然后将其与现存近亲物种(例如,猛犸象与亚洲象)的基因组进行比较。利用CRISPR技术,他们修改近亲物种的细胞,使其与灭绝物种的基因组匹配。最后,这些经过修改的细胞被植入卵子中,胚胎被植入代孕母亲体内。 除了复活灭绝物种的核心目标外,Colossal Biosciences还开发了人工子宫技术,这项技术不仅对复活灭绝物种有帮助,也具有潜在的医疗应用价值,例如在人类生育治疗和医疗保健方面。 Colossal Biosciences的商业模式主要包括三个方面:首先,他们通过衍生科技公司来实现商业化,例如,他们已经成功推出了两家公司:Breaking(利用生物微生物分解塑料垃圾)和FormBio(一个用于开发基因疗法的计算生物学平台)。其次,他们与政府合作开展濒危物种保护项目,例如,他们可以帮助拯救仅剩两只雌性的北方白犀牛。最后,他们正在进军新兴的生物多样性信用市场,这类似于碳信用,但侧重于生物多样性恢复。 Colossal Biosciences的故事说明,雄心壮志与技术创新相结合,可以产生巨大的价值,并带来意想不到的应用。他们追求看似不可能的目标,却在过程中开发出具有广泛应用的解决方案,例如人工子宫和塑料垃圾清理技术。这些间接应用都可能产生数十亿美元的收入。 从数据科学的角度来看,Colossal Biosciences的工作是计算生物学、遗传算法和高级数据分析如何改变我们对可能性的认知的完美例子。他们结合了海量的基因组数据集、用于基因分析的机器学习和精确的基因编辑技术,以实现令人瞠目结舌的效果。 除了猛犸象外,渡渡鸟和塔斯马尼亚虎也是Colossal Biosciences正在积极研究的复活对象。其他公司也在尝试复活其他灭绝动物,例如旅鸽、加勒比僧海豹等。 总而言之,Colossal Biosciences的努力不仅可能使我们能够看到复活的灭绝动物,也为我们带来了许多其他生物技术创新。这再次证明,追求看似不可能的目标,可能会带来最具价值的创新。

This is episode number 866 on bringing extinct animals back to life.

Welcome back to the Super Data Science Podcast. I am your host, Jon Krohn. Let's start off with a couple quick recent reviews of the show. First one's an Apple podcast review from Raphael Bichesmille, a bioinformatics professional in Virginia. He says, "Thank you for your efforts in making data science accessible to everyone. Whenever I meet a data scientist in the DC area, I always make sure to mention your podcast."

Cool. Thanks, Raphael. Hopefully see you at the RVA Tech Data and AI Summit on March 19th, where I'll be giving the opening keynote. That is in Virginia, where you live. So that'd be cool. Our second review today comes from Ayesha Nassim, who's a senior consultant AI engineer at Ernst & Young in Maryland. She says, thank you for the great work you are doing, helping and inspiring me, me, and many like me. Bye.

I'm honored, Aisha. I'm so delighted to hear that. Thanks to everyone for all the recent ratings and feedback on Apple Podcasts, Spotify, and all the other podcasting platforms out there, as well as for all the likes and comments on our YouTube videos. If you happen...

To make an Apple podcast review where you type one out, I will read it on air, just like I read today's reviews on air. All right, for this week's five-minute Friday-style episode, I'm diving into a biotechnology story I found mind-blowing, and that's bringing back extinct animals like the woolly mammoth and the dodo bird.

Specifically, today's episode is mostly about a firm called Colossal Biosciences that recently secured a staggering $200 million Series C funding round. What's even more remarkable is the valuation at over $10 billion. That's a nearly seven-fold increase from their previous valuation just a couple of years ago.

Now, you might be wondering, as I certainly did, why investors would pour such enormous capital into a company that hasn't generated revenue yet and whose main projects aren't projected to be completed until 2028. Well, the answer lies in the intersection of technological innovation and commercial potential.

First, let me break down how their de-extinction process works. In the case of collision, they map the entire genome of extinct species like the woolly mammoth. Then they compare the genome of that to a close living relative. In the mammoth's case, for example, that's the Asian elephant. Using CRISPR gene editing technology, if you haven't heard of CRISPR before, I've got a link to that in the show notes.

So yeah, using CRISPR, they modify the elephant's cells to match the mammoth's genetic profile. Finally, these modified cells are placed into an egg and the embryo is implanted into an elephant surrogate mother. To achieve their ambitious de-extinction goal, Colossal has developed numerous breakthrough technologies. One of the most interesting is their artificial womb technology because it isn't just about bringing back extinct species, it has the potential in human fertility treatment and healthcare as well.

With a bit of context on Colossal's tech in our back pocket, let's now get into the three key ways that they're creating commercial value. First, they're spinning off technology companies. They've already launched two successful ventures, Breaking, which uses biological microorganisms to break down plastic waste into harmless organic matter, and another firm called FormBio, a computational biology platform for developing gene therapies.

These spinoffs have already secured millions in additional funding. The second business model is Colossals collaborating with governments on conservation projects for endangered species. For example, the northern white rhinoceros technically isn't extinct, but there are only two left and they're both female. So that's a place where Colossal could make an impact. And third, finally, Colossals positioning themselves to enter the emerging biodiversity credits market. This is something like carbon credits, but for biodiversity restoration.

A lesson for me about this story is how it demonstrates the exponential value of ambition paired with technological innovation. When you set out to solve really ambitious, really hard problems like bringing back extinct species, you can develop solutions that have widespread applications across multiple industries, like the artificial wombs for human fertility and the cleanup of plastic waste that I mentioned above.

Each one of the indirect applications Colossal has developed while pursuing their core mission of de-extinction could have such a large impact on their own that each could eventually generate billions of dollars of revenue.

From a data science perspective, Colossal's work is a perfect example of how computational biology, genetic algorithms, and advanced data analysis are transforming what we thought was possible. The company's work combines massive genomic datasets, machine learning for genetic analysis, and precision gene editing technologies to potentially jaw-dropping effect. Perhaps it won't be too long before you can head to a zoo to see a woolly mammoth.

What other animals other than woolly mammoths are candidates for de-extinction? Well, we probably won't have a Jurassic Park like in the film series because well-preserved DNA samples are critical for de-extinction. We also need a closely related living species that can serve as a surrogate in a suitable habitat needs to still exist for the de-extincted animal to be reintroduced into. So yeah.

Probably no dinosaurs, but some other candidate animals include the dodo bird and the Tasmanian tiger, both of which are active colossal projects.

And there's also a passenger pigeon project, which is being tackled by a different firm called Revive and Restore. Other potential animals that we could de-extinct include the Caribbean monk seal, the quagga, a subspecies of plains zebra, the great auk, which is a flightless bird from the North Atlantic, and the heath hen, which is a subspecies of prairie chicken. Pretty wild, no?

Whether de-extinction ends up working out or not, the big mission is bringing us a slew of other biotechnological innovations, which brings me back to my inspirational thought of the week. Sometimes, the most valuable innovations come not from trying to solve immediate market needs, but from pursuing seemingly impossible dreams.

What seemingly impossible goals could you be dreaming up to tackle by leveraging the exponential technologies that are available at your fingertips? Thanks to AI, your dreaming could be computationally augmented, if you like, potentially to great effect. If you don't already have some impossible goals in mind, you can head to your favorite conversational AI interface. As of the past few weeks, that might be OpenAI's deep research or Google's deep research features, which are tremendously powerful for big questions like this, and I've got links to those in

in the show notes for more information. And maybe we'll have an upcoming episode about them too. All right, that's it for today's episode. If you enjoyed it or know someone who might consider sharing this episode with them, leave a review of the show on your favorite podcasting platform, tag me in a LinkedIn or Twitter post with your thoughts. And if you aren't already, obviously subscribe to the show. Most importantly, however, I just hope you'll keep on listening. Until next time, keep on rocking it out there. And I'm looking forward to enjoying another round of the Super Data Science Podcast with you very soon.
