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. Sweeping tariffs could threaten the US manufacturing rebound Despite the geopolitical chaos and market collapses triggered by President Trump’s announcement of broad tariffs on international goods, some supporters still hope the strategy will produce a “golden age” of American industry. None of that is good for those planning to invest in US manufacturing. The longer-terms effects of the tariffs are, of course, unknown. And it’s that uncertainty, above all else, that could derail a reindustrialization still in the early stages for much of the country.Read the full story. —David Rotman AI is pushing the limits of the physical world Architecture often assumes a binary between built projects and theoretical ones. What physics allows in actual buildings, after all, is vastly different from what architects can imagine and design. That imagination has long been supported and enabled by design technology, but the latest advancements in artificial intelligence have prompted a surge in the theoretical.

One more thing The quest to figure out farming on Mars Once upon a time, water flowed across the surface of Mars. Waves lapped against shorelines, strong winds gusted and howled, and driving rain fell from thick, cloudy skies. It wasn’t really so different from our own planet 4 billion years ago, except for one crucial detail—its size. Mars is about half the diameter of Earth, and that’s where things went wrong. The Martian core cooled quickly, soon leaving the planet without a magnetic field. This, in turn, left it vulnerable to the solar wind, which swept away much of its atmosphere. Without a critical shield from the sun’s ultraviolet rays, Mars could not retain its heat. Some of the oceans evaporated, and the subsurface absorbed the rest, with only a bit of water left behind and frozen at its poles. If ever a blade of grass grew on Mars, those days are over.  But could they begin again? And what would it take to grow plants to feed future astronauts on Mars? Read the full story. —David W.
