  Fountains of diamonds that erupt from Earth's center are revealing the lost history of supercontinents News By Stephanie Pappas published January 14, 2024 Diamonds seem to reach Earth's surface in massive volcanic eruptions when supercontinents break up, and they form when continents come together. Comments (0) Diamonds erupt at the surface of the planet when supercontinents break up. Studying these sparkly gems can reveal secrets about our planet's deep history. (Image credit: Rory McNicol for Live Science) In the twilight of the Cretaceous, 86 million years ago, a volcanic fissure in what is now South Africa rumbled to life. Below the surface, magma from hundreds of miles down shot upward as fast as a car on the autobahn — if that car were barreling through solid rock — chewing up rocks and minerals and carrying them toward the surface in a reverse avalanche. What this looked like on the surface

  Revisiting causality using stochastics:  2. Applications Demetris Koutsoyiannis , Christian Onof , Antonis Christofidis and Zbigniew W. Kundzewicz Published: 25 May 2022 https://doi.org/10.1098/rspa.2021.0836 Review history Abstract In a companion paper, we develop the theoretical background of a stochastic approach to causality with the objective of formulating necessary conditions that are operationally useful in identifying or falsifying causality claims. Starting from the idea of stochastic causal systems, the approach extends it to the more general concept of hen-or-egg causality, which includes as special cases the classic causal, and the potentially causal and anti-causal systems. The framework developed is applicable to large-scale open systems, which are neither controllable nor repeatable. In this paper, we illustrate and showcase the proposed framework in a number of case studies. Some of them are controlled synthetic ex
