A little randomness improves the navigation of robot swarms in crowded environments

  • No comments
Researchers from the United States and the Netherlands have shown that controlled randomness in the movement path of robots reduces traffic jams and improves the rate of task completion, without the need for a powerful central computer or complex coordination.

The United States Secretary of War is preparing for war in the age of artificial intelligence.

A new strategic document calls on the US military to operate in a “wartime” format, adopt agent-based artificial intelligence at an unprecedented pace – and entrust autonomous systems with critical roles on the battlefield

Researchers at the Perimeter Institute have developed KiSS-SIDM, a computational tool that bridges intermediate regimes in a model of self-interacting dark matter, and may improve the understanding of core collapse and even the formation of black holes.

Life from motion: New discovery reveals how order is born from rotation

  • No comments
Tel Aviv University researchers have discovered that particles spinning in opposite directions in a liquid self-organize into polymer-like “active” chains that move, rotate, and exchange “partners” — a phenomenon that may shed light on self-organization processes in nature and lead to

Beyond the threshold: a new visualization of a black hole at NASA allows viewers to dive into the event horizon

A NASA astrophysicist has developed immersive simulations of a black hole using a supercomputer. These visuals illustrate two scenarios: a last-minute escape or crossing the event horizon and falling into the black hole
Scientists have discovered a large black hole that "hiccups", and emits gas fluxes. Analysis revealed that a small black hole repeatedly punctures the gas disk of the large black hole, causing the perturbations to be released. Strong magnetic fields, north and south of the black hole, shown by the orange cone, shoot the flux up and out of the disk. Each time the small black hole punctures the disk, it emits another star, in a regular periodic pattern. Credit: Jose-Luis Olivares, MIT
