Eddy-mean flow energy exchange depends on three variables

Researchers found that the eddy-mean kinetic energy exchange term is separated into three parts: one associated with cross-stream variation, one with along-stream variation, and one with mean flow direction. This new framework describes eddy-mean energy exchange without accounting for forces or physical properties.

Global retreat of glaciers has strongly accelerated

Since the turn of the millennium, glaciers worldwide have lost around 273 billion tonnes of ice per year, corresponding to about five and a half times the volume of Lake Constance. The loss of ice from glaciers has led to a rise in sea level of 18 millimetres, making it the second strongest driver of sea level rise after ocean warming.

Did Twitter favour tweets from right-wing politicians? International study ends prematurely in 2023

Researchers analyzed 8,600 politician accounts from 12 countries and found no significant difference in engagement patterns between left and right-leaning politicians. However, they observed a considerable increase in likes after Musk's acquisition, which may be due to early followers' increased support.
