black holes blows monumental bubbles of hundreds of thousands of light-years
An international team of researchers observed the full extent of the evolution of hot gas produced by an active black hole for the first time. As it evolves, the hot gas encompasses a much larger area than previously thought and even impacts objects residing at great distances. Their study is published…

Why do birds flock? Shedding light on collective motions in heterogeneous populations
Leiden physicists Alexandre Morin and Samadarshi Maity study self-organisation and flocking phenomena. They shed light on flocking, which helps to understand how it is possible that birds in a flock don't collide. With plastic microbeads, they create an experimental setup and they developed a mathematical…
