The Download: learning from environmental DNA, and why we should welcome watermarks

by News7

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.

How environmental DNA is giving scientists a new way to understand our world Environmental DNA is a relatively inexpensive, widespread, potentially automated way to observe the diversity and distribution of life. 

Unlike previous techniques, which could identify DNA from, say, a single organism, the method also collects the swirling cloud of other genetic material that surrounds it. It can serve as a surveillance tool, offering researchers a means of detecting the seemingly undetectable. By sampling eDNA, or mixtures of genetic material in water, soil, ice cores, cotton swabs, or practically any environment imaginable, even thin air, it is now possible to search for a specific organism or assemble a snapshot of all the organisms in a given place.

It offers a thrilling — and potentially chilling — way to collect information about organisms, including humans, as they go about their everyday business. Read the full story.

Why Big Tech’s watermarking plans are some welcome good news The world of AI has produced some depressing headlines recently, from the Taylor Swift AI-generated porn scandal to the proliferation of political deepfakes as election campaigns get underway in many countries around the world. But there’s a glimmer of good news in there, too: tech companies are stepping up and putting into place measures to better detect AI-generated content.

Meta has promised to start labeling AI-generated images on its platforms, and Big Tech is throwing its weight behind “provenance” tech that explains where content came from and who—or what—created it. These methods are not foolproof, but they’re a start. And even better, alongside these sorts of voluntary measures, we’re starting to see binding regulations. Read the full story.

How megacities could lead the fight against climate change


April 2021

In 2050, 2.5 billion more people will live in cities than do today. As the world grows more urbanized, many cities are becoming more populous while also trying to reduce carbon emissions and blunt the impacts of climate change.

In the coming decades, cities will be engines of economic growth. But they must also play a key role in confronting climate change. Learn how some of the world’s biggest cities—called megacities—are rising to this challenge. Read the full story.
