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.
We’re consuming toxic chemicals. Now we need to figure out how they’re affecting us.
What are chemical pollutants doing to our bodies? It’s a timely question given that last week, people in Philadelphia cleared grocery shelves of bottled water after a toxic leak from a chemical plant spilled into a tributary of the Delaware River, a source of drinking water for 14 million people. And it was only last month that a train carrying a suite of other hazardous materials derailed in East Palestine, Ohio, unleashing an unknown quantity of toxic chemicals.
There’s no doubt that we are polluting the planet. In order to find out how these pollutants might be affecting our own bodies, we need to work out how we are exposed to them. Which chemicals are we inhaling, eating, and digesting? And how much? The field of exposomics, which seeks to study our exposure to pollutants, among other factors, could help to give us some much-needed answers. Read the full story.

The big story
Should we believe in—or even want—immortality?
Twenty years have passed since writer Jonathan Weiner first met Aubrey de Grey, the man with the Methuselah beard. Back then, Aubrey was already a True Believer in the quest for immortality. And he wasn’t yet a man in disgrace.
Weiner first met Aubrey in 2002, when Aubrey was still working as a computer programmer in the Department of Genetics at the University of Cambridge. He rapidly became a secular guru, a prophet of immortality—to the intense annoyance of most of the scientists in the aging field.
But Aubrey’s eagerness to convince believers they could live for centuries, millennia, or even longer, raises pertinent questions about what it is to want something we may not even believe in. Read the full story.
