Three billion years ago, Earth's life relied on a rare metal

In a new paper, an international team led by scientists from Charles University, Czechia, has brought evidence linking widespread release of methane (CH₄)—a strong greenhouse gas—from the Greenland Ice Sheet (GrIS) to a warmer period 9–4 thousand years ago. CH₄ has been detected at retreating glacier margins worldwide, raising concerns about potential climate feedbacks associated with their widespread retreat, but this is the first time that a study has systematically investigated the whole marg

A new model to predict how language changes over time has been developed by a statistical physicist at the University of Portsmouth. The model is a step towards understanding the "statistical physics of language," a scientific theory which borrows ideas from the physics of interacting particles to explain how words, accents, and dialects spread, shift, and disappear across regions and generations, and how they might change in future. The research is published in the journal Physical Review E.

The global financial order has entered a new, shifting and disruptive era of nationalism and these changes lay bare the difference between the haves and have nots, according to a new study by Charles Darwin University (CDU).
