Have you ever stopped to think about how your phone knows exactly which street you are on, or how an app warns you about the traffic jam just as you reach the roundabout? Behind that small everyday mi...
When we think of computers, we imagine machines that process zeros and ones. Quantum computers do something very different: they work with tiny particles that can be in several states at once. It soun...
Imagine a source of energy that does not pollute, that barely generates waste and that could power entire cities with a minimal amount of fuel. It is not science fiction: it is nuclear fusion, the sam...
There is a technology so small that it cannot be seen with the naked eye, not even with a normal microscope. It works at the scale of atoms and molecules, where the rules of the world we know change c...
For decades, computers have followed the same rules: they think in bits, which can only be 0 or 1. Everything we do today — watching a video, sending a message, playing — comes down, in the end, to mi...

When you open the map on your phone to get somewhere, there is something you almost never think about: at that very moment, a network of dozens of satellites orbiting about 20,000 kilometres up is wor...
The robots exploring the ocean: the seabed we know worse than Mars We have sent rovers to Mars, photographed the moons of Jupiter and built telescopes that gaze at the edge of the universe. But 80% of...
When we look at the sky at night, every star we see is, in reality, an enormous power plant. For millions of years, the Sun and all the other stars have produced their light thanks to a process called...
There is a computer capable of doing, in seconds, calculations that would take the world’s best computers thousands of years. It is not a science-fiction promise: it already exists, it works, an...
When we talk about renewable energy, we almost always think of the sun and the wind. But there is another candidate that has been making a strong case for years and promises to solve one of the great ...
For decades, nuclear fusion seemed like a promise that always arrived «in thirty years». Well: 2026 is one of those years in which that phrase is starting to sound less like a joke. Several projects h...
