The Download: three-parent baby issues, and a solar balloon test
This is today’s edition of The Download our weekday newsletter that provides a daily dose of what’s going on in the world of technology.
Three-parent baby technique could create babies at risk of severe disease
When the first baby born using a controversial procedure that meant he had three genetic parents was born back in 2016, it made headlines. The baby boy inherited most of his DNA from his mother and father, but he also had a tiny amount from a third person.
The idea was to avoid having the baby inherit a fatal illness. His mother carried genes for a disease in her mitochondria. Swapping these with genes from a donor—a third genetic parent—could prevent the baby from developing it. The strategy seemed to work.
But it might not always be successful. MIT Technology Review can reveal two cases in which babies conceived with the procedure have shown what scientists call “reversion.” In both cases, the proportion of mitochondrial genes from the child’s mother has increased over time, from less than 1% in both embryos to around 50% in one baby and 72% in another.
Fortunately, both babies were born to parents without genes for mitochondrial disease. But the scientists behind the work believe that around one in five babies born using the three-parent technique could eventually inherit high levels of their mothers’ mitochondrial genes.
For babies born to people with disease-causing mutations, this could spell disaster—leaving them with devastating and potentially fatal illness. Read the full story.

Researchers launched a solar geoengineering test flight in the UK last year
Last September, researchers in the UK launched a high-altitude weather balloon that released a few hundred grams of sulfur dioxide into the stratosphere, a potential scientific first in the solar geoengineering field, MIT Technology Review can reveal.
In theory, spraying sulfur dioxide in the stratosphere could mimic a cooling effect that occurs in the aftermath of major volcanic eruptions, reflecting more sunlight into space in a bid to ease global warming. It’s highly controversial given concerns about potential unintended consequences, among other issues.
But the UK effort was not a geoengineering experiment. Rather, the stated goal was to evaluate a low-cost, controllable, recoverable balloon system. And some are concerned that the effort went ahead without broader public disclosures and engagement in advance. Read the full story.

The Download: inside the first CRISPR treatment, and smarter robots
This is today’s edition of The Download our weekday newsletter that provides a daily dose of what’s going on in the world of technology.
The lucky break behind the first CRISPR treatment
The world’s first commercial gene-editing treatment is set to start changing the lives of people with sickle-cell disease. It’s called Casgevy, and it was approved last month in the UK. US approval is pending this week.
The treatment, which will be sold in the US by Vertex Pharmaceuticals, employs CRISPR, which can be easily programmed by scientists to cut DNA at precise locations they choose.
But where do you aim CRISPR, and how did the researchers know what DNA to change? That’s the lesser-known story of the sickle-cell breakthrough, which doesn’t rely on fixing the genes responsible for the mutation that leaves patients’ hemoglobin molecules misshapen. Instead, it’s a kind of molecular bank shot—thankfully, one with a happy ending. Read the full story.

+ The first CRISPR cure might kick-start the next big patent battle. Vertex Pharmaceuticals plans to sell a gene-editing treatment for sickle-cell disease. A patent on CRISPR could stand in the way. Read the full story.
These robots know when to ask for help
The news: A new robot training model, dubbed “KnowNo,” aims to teach robots to ask for our help when orders are unclear. At the same time, it ensures they seek clarification only when necessary, minimizing needless back-and-forth. The result is a smart assistant that tries to make sure it understands what you want without bothering you too much.
Why it matters: While robots can be powerful in many specific scenarios, they are often bad at generalized tasks that require common sense. That’s something large language models could help to fix, because they have a lot of common-sense knowledge baked in. Read the full story.

Medical microrobots that travel inside the body are (still) on their way
The human body is a labyrinth of vessels and tubing, full of barriers that are difficult to break through. That poses a serious hurdle for doctors. Illness is often caused by problems that are hard to visualize and difficult to access. But imagine if we could deploy armies of tiny robots into the body to do the job for us. They could break up hard-to-reach clots, deliver drugs to even the most inaccessible tumors, and even help guide embryos toward implantation.
We’ve been hearing about the use of tiny robots in medicine for years, maybe even decades. And they’re still not here. But experts are adamant that medical microbots are finally coming, and that they could be a game changer for a number of serious diseases. Read the full story.

The lucky break behind the first CRISPR treatment
The world’s first commercial gene-editing treatment is set to start changing the lives of people with sickle-cell disease. It’s called Casgevy, and it was approved last month in the UK. US approval is pending this week.
The treatment, which will be sold in the US by Vertex Pharmaceuticals, employs CRISPR, the Nobel-winning molecular scissors that have had journalists scrambling for metaphors: “Swiss Army knife,” “molecular scalpel,” or DNA copy-and-paste. Indeed, CRISPR is revolutionary because scientists can so easily program it to cut DNA at precise locations they choose.
But where do you aim CRISPR? That’s the lesser-known story of the sickle-cell breakthrough. The disease is caused by faulty hemoglobin, the molecule that carries oxygen in the blood. To cure it, though, Vertex and its partner company, CRISPR Therapeutics, aren’t fixing the genes responsible for the mutation that leaves those molecules misshapen. Instead, the new treatment involves a kind of molecular bank shot—an edit that turns on fetal hemoglobin, a second form of the molecule which we have in the womb but lose as adults.
You can think of how the edit works as a kind of double negative. It adds a misspelling to the turbo-booster of another gene, BCL11A, that is itself what inhibits the production of fetal hemoglobin in adult bodies. Without that booster, there’s less inhibition, and more fetal hemoglobin. Got it?
“When you inhibit the enhancer, you inhibit the inhibitor,” says Daniel Bauer, a professor at Boston Children’s Hospital and Harvard University, who helped work it out. “It is kind of complicated.”
The important thing is a happy ending—and this edit really works. Some patients say they lived in fear of dying, either from an acute attack of sickling (when their red blood cells start blocking vessels) or from slow, insidious organ damage. Now early volunteers say they’re grateful—and, after living with disease their whole lives, even a little shocked—to be cured.
Newborn theory
The idea that fetal hemoglobin can protect against the disease is an old one. Sickle-cell is most common in people with African ancestry. A doctor on Long Island, Janet Watson, had noticed in 1948 that newborns never showed its signs—the main one being misshapen, crescent-shaped red blood cells. That was pretty odd for an inborn condition.
“Sickle-cell disease should occur in infancy as often as later in life,” Watson wrote. But since it didn’t, Watson hypothesized that the fetal form of the molecule, active in the womb, was protecting babies for a few months after birth, until it was replaced by the adult version: “The theory that at once presents itself is that fetal hemoglobin is unable to produce sickling.”
She was right. But it took another six decades to learn how the switch-over worked—and how to flip it back. Many of those discoveries were made in the laboratory of Stuart Orkin, a Harvard researcher who published his first paper in 1967 and who’s lived through several eras of research on blood diseases, starting near the dawn of molecular biology.
“I am one of the last men standing,” Orkin told me with a grin when I met him for a corned-beef sandwich.

He’s a clever scientist who a long time ago decided to study how the blood system is regulated. Logistically, it was a great topic; blood cells are easy to get hold of and study.
“I like to solve a problem, and here is a problem that could be solved,” Orkin says. “How does the system work, and then can you do anything about it?”
Special sauce
Bill Lundberg, the former chief scientific officer of CRISPR Therapeutics, the biotech that first started developing the treatment eight years ago (Vertex later joined as a partner), says the company’s sickle-cell project directly made use of Orkin’s findings. “Stu’s role is really underappreciated,

The Download: Google’s Gemini is here, and Sundar Pichai talks AI
This is today’s edition of The Download our weekday newsletter that provides a daily dose of what’s going on in the world of technology.
Google DeepMind’s new Gemini model looks amazing—but could signal peak AI hype
Hype about Gemini, Google DeepMind’s long-rumored response to OpenAI’s GPT-4, has been building for months. Now, the company has finally revealed what it has been working on in secret all this time. Was the hype justified? Yes—and no.
Gemini is Google’s biggest AI launch yet—its push to take on competitors OpenAI and Microsoft in the race for AI supremacy. There is no doubt that the model is pitched as best-in-class across a wide range of capabilities—an “everything machine.”
But while it’s a big step for Google, but not necessarily a giant leap for the field as a whole. Judging from its demos, it does many things very well—but few things that we haven’t seen before. Read the full story.

Google CEO Sundar Pichai on Gemini and the coming age of AI
This last year has largely been defined by the AI releases from one company: OpenAI. The rollout of DALL-E and GPT-3.5 last year, followed by GPT-4 this year, dominated the sector and kicked off an arms race between startups and tech giants alike
Now, with the release of Gemini, Google has thrown its hat into the ring. The new AI model reflects years of efforts from inside Google, overseen and driven by its CEO, Sundar Pichai.
Our editor-in-chief Mat Honan sat down with Pichai at Google’s offices in Mountain View, California, on the eve of Gemini’s launch to discuss what it will mean for the company, its products, AI, and society writ large. Read the full interview.
How carbon removal technology is like a time machine
By burning fossil fuels, we’ve released greenhouse gases by the gigaton. There’s a lot we can (and need to) do to slow and eventually stop these planet-warming emissions. But carbon removal technology has a different promise: turning the clock back.
Well, sort of. Carbon removal can’t literally take us back in time. But this time-machine analogy for thinking about carbon removal—specifically when it comes to the scale that will be needed to make a significant dent in our emissions—is a favorite of climate scientist David Ho.
Casey Crownhart, our climate reporter, has taken a look at what it might take for carbon removal to take us back far enough in time to reverse our mistakes—well, the emissions-related ones, anyway. Read the full story.
