North Korea's latest military reconaissance satellite launch ended in failure as the rocket exploded and fell into the Yellow Sea shortly after liftoff. Analysts say it shows progress in the country's space ambitions despite the setback.…

Present-day volcanism on Venus might be far more pervasive than previously believed. A new analysis of decades-old data from NASA’s Magellan spacecraft finds signs of fresh lava flows occurring on the Venusian surface between…

Small things can have big effects. Take the plant plankton that populates the Earth’s oceans. When zooplankton eats them, the phytoplankton releases a chemical called dimethyl sulphide (DMS) and it is this that people are referring to…

Researchers took over an amusement park attraction to test out an idea for how astronauts might exercise on the moon.

ChatGPT and other AI tools are upending our digital lives, but our AI interactions are about to get physical. Humanoid robots trained with a particular type of AI to sense and react to their world could lend a hand in factories,…

In the quest to build a quantum internet, scientists are putting their memories to the test. Quantum memories, that is. Quantum memories are devices that store fragile information in the realm of the very small. They’re an…

It’s a bit like seeing a world in a grain of sand. Except the view, in this case, is the exquisite detail inside a bit of human brain about half the size of a grain of rice. Held in that minuscule object is a complex collective…
