A small group of engineers cram themselves around a wooden table in a coworking space that still has the subtle scent of burnt coffee and fresh paint on a gloomy morning in Warsaw’s business district. There are only ten workers at their startup. Every other day, the office printer becomes stuck. However, San Francisco and London investors have begun phoning. There’s a subtle sense that the geography of billion-dollar startups might be changing as scenes like this take place in cities that don’t often make headlines in venture capital. The tale of startup success appeared to be foreseeable for many…

A small beauty salon on a quiet side street in Manchester last winter stayed open later than usual on a chilly evening. A woman was learning how to inject herself with something she had bought on Instagram in a back room while the front lights were dim and the waiting chairs were empty. The vial had come wrapped in plastic tape and kitchen paper. No guidelines. Not a prescription. There is a growing perception that the worldwide obsession with weight-loss injections has progressed more quickly than the mechanisms designed to regulate it, as scenes such as these take place in…

Last autumn, a software engineer was sitting in a quiet corner of a shared office space in downtown London on a rainy weekday morning, gazing at a screen full of lines of code. What used to require a week of meticulous work now appeared to happen in an afternoon. A tiny AI helper offered complete functions, fixed mistakes, and even suggested different strategies. There was an odd atmosphere in the room as they watched the project pick up speed; it was a mixture of excitement and disbelief. There seemed to be a fundamental change in the nature of work. Economists…

The conference rooms along Constitution Avenue seem unusually packed on a gloomy morning in Washington, D.C. Briefing folders bearing terms like “AI competitiveness” and “semiconductor resilience” are carried by economists, defense officials, and technology advisors as they move between meetings. Tourists stroll past monuments outside the buildings, oblivious to the more subdued discussion taking place inside: how to prevail in a technological race that is becoming more and more geopolitical. For many years, Silicon Valley was the primary hub for technology leadership. Businesses moved quickly, governments largely remained in the background, and venture capital and aspirational founders appeared to be…

The air surrounding Cape Canaveral has a subtle rocket fuel and salt odor early on a humid Florida morning. The Apollo missions’ former launch facilities are traversed by workers wearing reflective vests. After the space shuttle was retired, some of those same launch pads remained silent for years while rust gradually spread across the metal buildings. They’re back to work now. Trucks rumble by. Engineers travel between hangars with coffee cups and laptops. The peculiar thing is that a large number of them are not employed by the government. Ownership of space exploration has subtly shifted. National governments controlled almost…

A small group of tourists stood outside a wooden lodge with a view of a frozen lake late one evening in northern Finland. A nearby chimney gave off a subtle scent of pine smoke. The sky initially appeared normal—clear, black, and starry. Then the horizon started to stretch with a pale green band. It changed into something almost theatrical in a matter of minutes: neon curtains floating slowly above the trees, rippling waves of light, and crimson streaks. Quietly, one of the guides shook his head. Even those who make a living by watching the aurora appeared taken aback. In…

Chalkboards in theoretical physics departments, such as those in Cambridge, Princeton, or Berlin, frequently become covered in odd symbols that resemble decorations late at night. Curves that squirm. Greek characters. lengthy integral chains. It may appear to be a mysterious language to outsiders. However, some physicists who have been staring at those boards lately have started to suspect something strange and strangely beautiful: the violent chaos inside black holes might actually follow hidden mathematical patterns. At first, that concept seems nearly ridiculous. After all, black holes are renowned for consuming all matter, light, and information. Even Einstein’s equations start to…

Engineers in fleece jackets wait in line for espresso in glass-walled offices with a view of the hills on a foggy morning in the San Francisco Bay Area. A few blocks away, in peaceful biotechnology labs bustling with incubators and refrigeration units, researchers are examining something Silicon Valley once thought was well outside its purview: aging. Not wellness fads or wrinkles. aging itself. The gradual disintegration of cells that ultimately ends every human tale. It’s difficult to ignore how seriously the tech industry has started to take this issue. Silicon Valley concentrated on software, networks, and data for many years.…

Rows of computers glow late into the night on a calm floor of a Cambridge, Massachusetts, biomedical research facility. Robotic arms move slowly between trays of chemical samples while glass flasks are illuminated by bright white lights inside a nearby laboratory. Scientists have had to deal with situations like this for many years. However, something strange is currently taking place. These labs are producing some of the most promising drug candidates, some of which are no longer solely human-designed. Artificial intelligence suggests them, sometimes in an unexpected way. The process of finding new drugs has always been excruciatingly slow. It…

During the hottest weeks of the year, midday in Bamako can seem almost unreal. As though the air itself has become liquid, the streets shimmer. Shopkeepers withdraw further into shaded doorways as motorbikes pass slowly, their riders covering their faces with scarves. Naturally, the Sahel has always been hot. However, many locals discreetly report that the heat feels different these days—heavy, prolonged, and somehow less forgiving. Researchers studying climate change have begun to quantify that emotion. Scientists have been monitoring this trend for decades: temperatures in the Sahel region of Africa are rising at a rate that is roughly 1.5…
