Plus: Conspiracy theorists are spreading Russia's unfounded "dirty bomb" claims

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.

Introducing: The Mortality Issue

From the moment you’re born, the one thing you can be completely certain of is that you will die. But what if aging isn’t inevitable, after all? And if you could slow, or even turn back the clock, would you?

Here’s a selection of some of the new stories in the edition, guaranteed to get you thinking about what comes next.

The app remains obscure among most people, though it marks another high-profile attempt by yet another Chinese tech giant to try its luck in the American e-commerce market. So how did Temu rise to the top of the iOS App Store’s shopping chart? Read the full story.

The big story

This is how AI bias really happens—and why it’s so hard to fix

February 2019

If we want to be able to fix bias in AI, we need to understand the mechanics of how it arises in the first place.

We often shorthand our explanation of AI bias by blaming it on biased training data, but the reality is more nuanced. Bias can creep in long before the data is collected as well as at many other stages of the deep-learning process—and can be incredibly hard to fix. Read the full story.
