The Download: coping in a time of arrhythmia, and DNA data storage

This is today's edition ofThe Download,our weekday newsletter that provides a daily dose of what's going on in the world of technology.

The arrhythmia of our current age

Arrhythmia means the heart beats, but not in proper time-a critical rhythm of life suddenly going rogue and unpredictable. It's frightening to experience, but what if it's also a good metaphor for our current times? That a pulse once seemingly so steady is now less sure. Perhaps this wobbliness might be extrapolated into a broader sense of life in the 2020s.

Maybe you feel it, too-that the world seems to have skipped more than a beat or two as demagogues rant and democracy shudders, hurricanes rage, and glaciers dissolve. We can't stop watching tiny screens where influencers pitch products we don't need alongside news about senseless wars that destroy, murder, and maim tens-of-thousands.

All the resulting anxiety has been hard on our hearts-literally and metaphorically. Read the full story.

An easier-to-use technique for storing data in DNA is inspired by our cells

The news: It turns out that you don't need to be a scientist to encode data in DNA. Researchers have been working on DNA-based data storage for decades, but a new template-based method inspired by our cells' chemical processes is easy enough for even nonscientists to practice.

Some background: So far, the process of storing data in DNA has been expensive, time consuming, and error prone. It also required skilled expertise to carry out.

The details: The new method is more efficient and easy enough that anyone can do it. They enlisted 60 students-studying all sorts of topics, not just science-to test it out, and the trial was a success. It could pave the way for an unusual but ultra-stable way to store information.

The big story

How Worldcoin recruited its first half a million test users

WORLDCOIN

April 2022

In December 2021, residents of the village of Gunungguruh, Indonesia, were curious when technology company Worldcoin turned up at a local school. It was pitched as a new, collectively owned global currency that will be distributed fairly to as many people as possible," in exchange for an iris scan and other personal data.

Gunungguruh was not alone in receiving a visit from Worldcoin. MIT Technology Review has interviewed over 35 individuals in six countries who either worked for or on behalf of Worldcoin, had been scanned, or were unsuccessfully recruited to participate.

Our investigation reveals wide gaps between Worldcoin's public messaging, which focused on protecting privacy, and what users experienced. We found that the company's representatives used deceptive marketing practices, and failed to obtain meaningful informed consent. Read the full investigation.
