Scientists in Japan have discovered that tiny steps just one atom high can act like microscopic railroad tracks, guiding the movement of quantum vortices inside an ultrathin superconductor. Under certain conditions, these vortices moved more than 1,000 times more easily along the steps than across them. Researchers also found that they could adjust this remarkable effect simply by changing the temperature or magnetic field.
The discovery was made by researchers at the Research Center for Materials Nanoarchitectonics (MANA), part of Japan's National Institute for Materials Science (NIMS). Their findings offer a promising new approach to controlling quantum behavior and could eventually help engineers develop superconducting electronics that use far less energy while processing information more efficiently.

Scientists just pushed superconductors beyond their usual current limit - Science Daily
Superconductors are among the most remarkable materials in quantum physics. When certain materials are cooled below a specific transition temperature, their electrical resistance disappears. Electricity can then flow through them without losing energy as heat. This happens because electrons form correlated pairs called Cooper pairs. Instead of moving independently, these pairs act collectively, somewhat like a wave traveling through the material. This unusual property makes superconductors promising for applications including powerful magnets, highly sensitive detectors, and quantum circuits.

Did an eruption of poop trigger the biggest explosion of life and diversity Earth has ever seen? - BBC Wildlife Magazine
The history of life on Earth doesn’t start with the Cambrian Explosion. However, this was the point in time that nearly all major animal groups appeared, proliferated, and diversified. It wiped out 90% of life on Earth, turned the oceans into graveyards – and it very nearly ended life on our planet entirely
