A more precise model of the Earth's ionosphere

The ionosphere—the region of geospace spanning from 60 to 1000 kilometers above the Earth—impairs the propagation of radio signals from global navigation satellite systems (GNSS) with its electrically charged particles. ...

Why are networks stable? Researchers solve a 50-year-old puzzle

A single species invades an ecosystem causing its collapse. A cyberattack on the power system causes a major breakdown. These types of events are always on our minds, yet they rarely result in such significant consequences. ...
