For us, as a show on a public media budget, one of the best ways you can help us grow and thrive is to follow us from wherever you're listening. Thank you. We appreciate you. You're listening to Short Wave from NPR. Hey, short waivers. Regina Barber here with a list.

• 0:47Regina Barber?

  Made from our friends over at MIT Technology Review.

• 0:51Speaker 02

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

• 0:56Regina 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.

• 1:05Speaker 02

  We're really looking for high-impact advances that we think will change the way we live and work in the future.

• 1:10Regina Barber?

  For better, like?

• 1:11Speaker 02

  Potentially help us solve major problems like climate change or improve our well-being and our health as humans.

• 1:18Regina Barber?

  And for worse.

• 1:19Speaker 02

  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.

• 1:29Regina 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.

• 1:42Speaker 02

  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.

• 1:50Regina Barber?

  So today 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.

• 2:00Speaker 02

  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.

• 3:38Regina Barber?

  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 will focus on sodium ion batteries. What's the big deal there?

• 3:55Speaker 02

  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.

• 4:28Regina Barber?

  Yeah, what would this switch mean for like the EV market in the long term?

• 4:32Speaker 02

  It would give manufacturers another option for EVs and one that is, you know, 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 be 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.

• 5:02Regina 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?

• 5:16Speaker 02

  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 few minutes to provide people with the experience of weightlessness and just, you know, private citizens, not 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

• 5:58Speaker 02

  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.

• 6:09Regina 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?

• 6:14Speaker 02

  Yeah, I gotta 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 like luxury space experience, for lack of a better word. So Axiom is one that has, you know, contracted with like a famous French architect and designer to design the inside. It has space suits designed by Prada. There's different amenities in some of these, 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.

• 6:54Regina Barber?

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

• 7:00Speaker 02

  That's a really fair question. I mean, we could see, you know, 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, you know, might not have otherwise had time on the International Space Station to devote to that research. So there could be some kind of second, 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.

• 7:35Regina 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?

• 7:43Speaker 02

  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 KJ 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 genetic 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, 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.

• 8:28Speaker 02

  So we think it's, you know, 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.

• 8:49Regina Barber?

  What are the hopes and the worries about this technology?

• 8:52Speaker 02

  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. It will certainly likely be very expensive because we're talking here about a treatment for, literally designed for one person.

• 9:17Regina Barber?

  One person, yeah.

• 9:18Speaker 02

  The estimates I heard with this one example were between $800,000 to $1 million, which is roughly maybe the cost of a liver transplant, but certainly out of reach for many.

• 9:28Regina Barber?

  What could be the impact in decades to come?

• 9:30Speaker 02

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

• 9:58Regina Barber?

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

• 10:08Speaker 02

  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."

• 10:51Regina Barber?

  It goes into eugenics?

• 10:53Speaker 02

  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. A lot of the genetic disorders that... This testing had provided guidance on 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.

• 11:35Regina Barber?

  Okay, Amy, we're gonna go through a few more rapid fire style, number one, next gen nuclear.

• 11:42Speaker 02

  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.

• 12:10Regina Barber?

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

• 12:17Speaker 02

  So everybody's been using, you know, 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 huge investment going into building more data centers by lots of different companies. And these are really a new breed of infrastructure. There are 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.

• 12:49Regina Barber?

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

• 12:55Speaker 02

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

• 13:02Regina Barber?

  Right, but they might not be coming back, but yes.

• 13:05Speaker 02

  They might not be coming back. And so we were quite careful with our, 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.

• 13:30Regina Barber?

  Endangered species get more genetic diversity by reintroducing genes from past organisms. So maybe we're not resurrecting the woolly mammoth, but we might be helping endangered species survive. I think that's the more accurate way to think about it, yes. Amy, thank you so much for coming back on the show. I love hearing about this list every year. Please come back next year. It's been a pleasure. I'd love to talk about it with you again in 2027.
