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.

+ I received the new gene-editing drug for sickle cell disease. It changed my life. As a patient enrolled in a clinical trial for Vertex’s new exa-cel treatment, Jimi Olaghere was among the first to experience CRISPR’s transformative effects. 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 big story

A plan to redesign the internet could make apps that no one controls

July 2020

Back in the early days of the accessible internet, many of its pioneers championed a free and open internet controlled by its users. Fast-forward a quarter-century and that vision feels naïve.

It’s clear that a desire for revolution is brewing, led in part by Dfinity, a non-profit building what it calls the internet computer, a decentralized technology that allows software to run anywhere on the internet rather than in server farms controlled by large firms.

But this desire for a rewilding of the internet is not about nostalgia. It’s about fighting back against the dominance of Big Tech, and mitigating the harms it’s inflicting on society. Read the full story.
