Vertex developed a CRISPR cure. It’s already on the hunt for something better.
The company that just got approval to sell the first gene-editing treatment in history, for sickle-cell disease, is already looking for an ordinary drug that could take its place. Vertex Pharmaceuticals has a 50-person team working to make a pill that doesn’t do gene editing at all—but achieves the same treatment goals.
Now that medicine’s CRISPR era has begun, some of the technique’s limitations are already visible. The treatment, called Casgevy, is both tough on patients and hugely expensive, with many barriers to access. Such drawbacks are why a pill to alleviate sickle-cell, if developed, could sweep CRISPR from the playing field. Read the full story.

Now we know what OpenAI’s superalignment team has been up to
OpenAI has announced the first results from its superalignment team, the firm’s in-house initiative dedicated to preventing a superintelligence—a hypothetical future computer that can outsmart humans—from going rogue.
While many researchers still question whether machines will ever match human intelligence, let alone outmatch it, OpenAI’s team takes machines’ eventual superiority as given.
In a low-key research paper, the team describes a technique that lets a less powerful large language model supervise a more powerful one—and suggests that this might be a small step toward figuring out how humans might supervise superhuman machines. Read the full story.

Google DeepMind used a large language model to solve an unsolvable math problem
The news: Google DeepMind has used a large language model to crack a famous unsolved problem in pure mathematics. The researchers say it is the first time a large language model has been used to discover a solution to a long-standing scientific puzzle—producing verifiable and valuable new information that did not previously exist.
Why it matters: Large language models have a reputation for making things up, not for providing new facts. Google DeepMind’s new tool, called FunSearch, could change that. It shows that they can indeed make discoveries—if they are coaxed just so, and if you throw out the majority of what they come up with. Read the full story.

Needle-free covid vaccines are (still) in the works
Covid shots do an admirable job of boosting our immune response enough to protect against serious illness, but they don’t boost immunity in the one spot we’d like them to: our airways.
That’s why researchers have been working on vaccines you breathe into your lungs or spray into your nose. The idea is that these vaccines will elicit an immune response in the mucous membranes of your respiratory tract that might help stave off infection or, if you do become infected, make you less likely to transmit the virus.
These “mucosal” covid vaccines aren’t available in the US or Europe, but they are in other parts of the world. So when will the US get its first mucosal covid vaccine? What will it look like? And will it work as intended? Read the full story.

The big story
These impossible instruments could change the future of music
When Gadi Sassoon met Michele Ducceschi backstage at a rock concert in Milan in 2016, the idea of making music with mile-long trumpets blown by dragon fire, or guitars strummed by needle-thin alien fingers, wasn’t yet on his mind.
At the time, Sassoon was simply blown away by the everyday sounds of the classical instruments that Ducceschi and his colleagues were re-creating with computers.
The sounds were the early results of a curious project at the University of Edinburgh in Scotland, where Ducceschi was a researcher at the time. The project aimed to produce the most lifelike digital music ever created—creating a combination of sounds that would be pretty much impossible to nail otherwise. Read the full story.
