13 researchers from the USA, Italy, Germany, the United Kingdom, and Spain have discovered new traces of the megaflood that returned the Mediterranean to the map: 5.97 million years ago, the sea turned into a salt desert for 640,000 years and was then invaded by the Atlantic in a geological catastrophe that still challenges science.

The USA and Ukraine signed an agreement in 2025 that gives Washington priority access to lithium, titanium, uranium, and rare earths in exchange for military aid. The country, which has one-third of Europe’s lithium reserves and 7% of the continent’s titanium, is negotiating sovereignty over resources worth trillions using geological maps made by the Soviet Union 60 years ago.
