Key Discussion Points & Insights

1. The Criteria for Breakthrough Technologies

• [01:02–01:47]
  Amy Nordrum outlines what earns a technology a spot on the list:
  • High-impact advancements expected to revolutionize daily life, work, health, and address global problems like climate change.
  • Both beneficial and potentially harmful technologies are included.
    • “For worse, we also include advances that we think are equally as significant but might have very negative consequences.” – Amy Nordrum [01:16]

2. Sodium-ion Batteries: A New Era for EVs

• [04:01–05:27]
• Sodium as a widely available, less environmentally damaging alternative to lithium for batteries.
• More stable and potentially up to one-third the cost of lithium-ion batteries as technology scales, eventually making EVs more affordable.
  • “Sodium ion batteries could shake that up really for the first time in a meaningful way if they're able to scale up.” – Amy Nordrum [04:20]

3. Private Space Stations and the Future of Space Travel

• [05:27–07:19]
• Growth of commercial suborbital flights and the imminent launch of private space stations, which aim to blend luxury (think Prada spacesuits) with scientific research.
• Enables more countries and companies to access space for research, diversifying participants beyond nation-state astronauts.
  • “There's this whole rash of new private space stations that are due to be launched over the next couple of years... with amenities...” – Amy Nordrum [06:39]
• Potential for space-derived discoveries in pharmaceuticals and semiconductors that impact life on Earth.

4. Gene-Edited Babies & Personalized Medicine

• [08:00–09:53]
• Landmark 2025 case: “KJ,” a baby treated for a rare disorder via a CRISPR-based method called “base editing” — the first highly personalized gene-editing treatment.
• Extremely high costs (up to $1 million), raising questions of accessibility.
  • “It was done with a newer form of CRISPR... base editing, that actually lets you rewrite individual letters.” – Amy Nordrum [08:22]
• Enormous future potential for rare genetic diseases but still in experimental stage.

5. Embryo Scoring and the Ethics of Genetic Selection

• [10:23–12:00]
• New embryo screening extends beyond disease prevention to selecting for preferred traits like intelligence or eye color — a practice Amy and Regina link to eugenics.
  • “There's a lot of people that see that in it and are concerned for that reason.” – Amy Nordrum [11:18]
• Limitations: Current science can only offer statistical probabilities, not guarantees.

6. Rapid-Fire Technologies

• [12:00–13:27]
  • Next-Generation Nuclear:
    • Advanced reactors could be built faster/cheaper, supporting urgent energy needs for an electrified future.
    • “There's a new generation of reactors... that could be built cheaper and perhaps more quickly, they're smaller in size.” – Amy Nordrum [12:07]
  • AI Data Centers:
    • Specialized, massive facilities with advanced cooling for AI computation.
    • “A new breed of infrastructure... hundreds of thousands of specialized chips called GPUs, and also require their own kind of very specialized cooling system.” – Amy Nordrum [12:42]
  • Gene Resurrection:
    • Using ancient genes for conservation — not Jurassic Park-style revivals but helping modern endangered species adapt.
    • “Help endangered species get more genetic diversity by reintroducing genes from past organisms.” – Amy Nordrum [13:27]

[Regina Barber]

Hey, shortwavers. Regina Barber here with a list made from our friends over at MIT Technology Review.

[Amy Nordrum]

This is the 25th year, actually that our newsroom has put out a list of 10 breakthrough technologies.

[Regina Barber]

This is Amy Nordrum, executive editor of that newsroom and she says that this list describes which technologies they think matter most each year.

[Amy Nordrum]

We're really looking for high impact advances that we think will change the way we live and work in the future for better, like potentially help us solve major problems like climate change or improve our well being and our health as humans. And for worse, we also include advances that we think are equally as significant but might have very negative consequences. We had military drones on the list a few years ago.

[Regina Barber]

This year, Amy says a large chunk of the list is on AI technology because that area has taken off. But they've also included other important advances that may not have risen above the noise for people not paying close attention.

[Amy Nordrum]

You know, what's going on in biotech or the latest climate progress, especially at a moment where it can feel like there's not as much being made generally, especially here in the US So today.

[Regina Barber]

On the show we go through some of the top 10 breakthrough technologies of 2026 by MIT Technology Review, including Amy's favorite on the list.

[Amy Nordrum]

This is so not fair. But I mean, I guess I always have a personal favorite, honestly, or one that I'm just kind of most interested in this time it's in the space category.

[Regina Barber]

Podcast okay Amy, let's start in the land of EVs. Right now they're generally made with lithium ion batteries. But mining lithium is it's harmful to the environment, it can have like poor labor conditions and it's a finite resource. So you all focus on sodium ion batteries. What's the big deal there?

[Amy Nordrum]

Well, lithium has really been the go to battery chemistry for decades at this point. And sodium ion batteries could shake that up really for the first time in a meaningful way if they're able to scale up and these batteries would be much easier to produce. Lithium supply is very concentrated to just a handful of countries, but you can find sodium everywhere. It's the same sodium that you find in sea salt. So this could make it much easier to produce batteries. And we're going to need more batteries over the coming decades to store renewable energy, to operate electric vehicles, to do all kinds of things in our lives. Yeah.

[Regina Barber]

What would this switch mean for the EV market in the long term?

[Amy Nordrum]

Well, it would give manufacturers another option for EVs and one that is made from a material that's much more abundant and less vulnerable to supply chain risks, for example. And over time, these might actually make EV batteries cheaper. Right now their sodium ion batteries are not cheaper than lithium ion, but as you scale up and produce more of them. Some analysts think that they could someday about a third of the as expensive as lithium ion batteries to produce. And in the end, that might help bring down the cost of an electric car and make it more affordable for more people.

[Regina Barber]

Okay, next tech, we're going to go into space. Okay, so so many, like sci fi books, movies that I love show humans, like, living in space, but to date, like, only a few hundred have actually made that trip. So how do you think that's going to change?

[Amy Nordrum]

Well, we've already started to see it change in the last couple of years. You know, we've seen companies like Blue Origin and Virgin Galactic offer suborbital flights of a minutes to provide people with the experience of weightlessness and just private citizens, not professionally trained astronauts. Even NASA has started allowing private astronauts to travel up to the ISS with a company called Axiom. And that's been happening for the last couple of years. But really what's changing now is that there's this whole rash of new private space stations that are due to be launched over the next couple of years and which will eventually replace the International Space Station, which has been operating for decades. And those private space stations will not just support government missions, but in many cases also private astronauts from companies that want to do research in space or people who just want to get a view outside, you know, a space station window of the Earth that we all live on.

[Regina Barber]

Can you give me, like, a visual, like, how big are these, you know, space stations going to be? What are they going to look like?

[Amy Nordrum]

Yeah, I got to say, they're going to look pretty fancy. Based on some of the mockups that I've seen. Some of the companies active here have been seemingly trying to provide a pretty luxury space experience, for lack of a better word. So Axiom is one that has contracted with a famous French architect and designer to design the inside. It has spacesuits designed by Prada. There's different amenities in some of these space stations, and they're not nearly as big as the International Space Station, Certainly not in these first iterations. They're a fraction of the size, really. Over time. They hope and intend to scale up to that. But in the next couple of years, we'll be seeing much smaller models launching.

[Regina Barber]

I mean, space travel sounds cool. Is there a larger impact to us here on Earth?

[Amy Nordrum]

That's a really fair question. I mean, we could see, for example, if this opens up access to more private companies doing research. Maybe there will be pharmaceuticals that are developed based on that research or new Kinds of electronics and semiconductors that companies might not have otherwise had time on the international space station to devote to that research. So there could be some kind of second, third order effects like that. And certainly a number of these private space companies intend to provide access to countries that have never before had access to the international space station or been able to send astronauts up there.

[Regina Barber]

Let's move on to gene edited babies. We've heard a lot about this for a while. Like, why did this make the list this year?

[Amy Nordrum]

Well, this year we put it on the list because there was a quite remarkable treatment done back In May of 2025, when a baby named K.J. was treated for a rare genetic condition that this baby had with a treatment, a gene editing treatment that was designed just for him. It's the first of its kind that's been personalized in this way. There have been other gene editing treatments Based on crispr in the past, but this one was designed just for KJ based on the misspelling in his DNA. And it was done with a newer form of crispr, the gene editing tool called base editing, that actually lets you rewrite individual letters Rather than just delete or snip out genes, as the first iteration of CRISPR did. So we think it's the first of its kind. And honestly, we don't know quite how it went yet. The baby seems to be doing much better this many months on, but it's the first example of this kind of new, highly personalized gene editing treatment that many more people could receive with very rare conditions that wouldn't otherwise be attractive to a pharmaceutical company to develop a treatment for.

[Regina Barber]

What are the hopes and the worries about this technology?

[Amy Nordrum]

Well, physicians, researchers that did this at the university of Pennsylvania, they'll need to continue to watch closely and see what the results were and whether there are any unintended effects. But they do tend to move forward with the trial on this technology so that they can actually get FDA approval for it. You know, it will certainly likely be very expensive because we're talking here about a treatment for literally designed for one person. Yeah, you know, the estimates I heard with this one example were between $800,000 to a million dollars, which is. Is roughly maybe the cost of a liver transplant, but certainly out of reach for many.

[Regina Barber]

What could be the impact in decades to come?

[Amy Nordrum]

It's a great question. I mean, there's, you know, potentially thousands of genetic diseases that could potentially, you know, be treated this way and are quite rare. And so people do need these. These personalized treatments. So you might think about brain diseases or muscular dystrophy as potential candidates. So, you know, over time this could be something ideally that would be, be available to many more people with many more different kinds of very rare genetic disorders.

[Regina Barber]

So this is not exactly the same, but it is on the list and it's kind of related to all this, something called embryo scoring. Can you talk about that bit?

[Amy Nordrum]

Sure, yes. So a lot of times people going through IVF today, they have the option to scan embryos prior to implantation for genetic diseases if they have one that they do not wish to pass on to their child. And this has been done for years. There's a lot of public support for this kind of thing and many parents choose to do that. And then lately we've also seen some companies start to advertise other services of similar kinds of tests, saying we're not just going to help you screen for severe genetic diseases that you might pass on, but we're going to help you actually pick your best embryo based on how intelligent that baby might grow up to be, or their eye color or their height and your preferences for your child.

[Regina Barber]

It goes into eugenics.

[Amy Nordrum]

Yeah, there's a lot of people that see that in it and are concerned for that reason. And then some of the companies providing this say that's not what we're doing. We're actually giving parents choice over the child that they have. But there's also just scientific questions. The genetic disorders that this testing had provided guidance on were, were due to like a single gene or a single base within a gene. Whereas these new traits that some of the companies are advertising, they're, they kind of come from many different interactions of genes. And so it's probability and it's, there's no guarantee that some of the services would actually reliably give you the outcome that you're, you're wanting for your child. Which to their credit, some of the companies do acknowledge with disclaimers on their their site.

[Regina Barber]

Okay, Amy, we're going to go through a few more rapid Firestyle number one, Next gen nuclear.

[Amy Nordrum]

And as your listeners probably know, we need more energy for all kinds of things in the future, whether it's heat pumps or AC or data centers. And one of the power sources that a lot of people are looking to is nuclear. But the problem is there's a lot of reactors in the past that have gone way over budget and taken a long time to build. Now there's a new generation of reactors being designed by a bunch of companies that you know, could be built cheaper and perhaps more quickly, they're smaller in size. They use different kinds of fuel or coolant.

[NPR Sponsor Announcer]

Wow.

[Amy Nordrum]

Okay.

[Regina Barber]

Number two, you mentioned it, data centers, but specifically AI data centers.

[Amy Nordrum]

So everybody's been using a lot of AI in their daily life, whether they honestly know it or not. It's built into all kinds of things that we use every day. And now there's a huge investment going into building more data centers by lots of different companies. And these are really a new breed of infrastructure. They're massive facilities that use hundreds of thousands of specialized chips called GPUs, and also require their own kind of very specialized cooling system. So this new class of infrastructure is something that we wanted to recognize on this year's list because it's unique to our time.

[Regina Barber]

And to round it all out, a slightly fun one, in my opinion, a gene resurrection.

[Amy Nordrum]

Well, you've heard a lot about extinct animals maybe that might be coming back, according to the claims of some companies.

[Regina Barber]

But they might not be coming back.

[Amy Nordrum]

But yes, they might not be coming back. And so we were quite careful with our framing of this. What we think is quite exciting, though, is the efforts around bringing back genes from ancient creatures into modern day animals or plants, often for conservation purposes or to help those plants adapt to climate change. There's been a lot of work in this ancient DNA space and now new efforts to, you know, help endangered species get more genetic diversity by reintroducing genes from past organisms.

[Regina Barber]

So maybe we're not resurrecting the woolly mammoth, but we might be helping endangered species survive.

[Amy Nordrum]

I think that's the more accurate way to think about it. Yes.

[Regina Barber]

Amy, thank you so much for coming back on the show. I love hearing about this list every year. Please come back next year.

[Amy Nordrum]

This is Hourglass on this American Life. One thing we like is a good mystery sometimes about really big things. But most times the little mysteries are the best.

[Amy Nordrum]

Our lost and found is currently filled with pants. I don't know. I've never seen this happen. Is this true?

[Ira Glass]

This is true. Mysteries of every size. Each week, this American Life, wherever you.
