Super-deep diamonds are geological time capsules: they contain minerals never found in nature

Super-deep diamonds are geological time capsules: they contain minerals never found in nature

The structure of super-deep diamonds protects them from the transformations they would normally undergo during their ascent into the Earth’s mantle. The Earth’s mantle It represents more than 80% of the volume of our planet, yet its deepest regions remain completely inaccessible to human technology. The lower mantlewhich extends from approximately 660 to 2,900 kilometers deep, cannot be reached directly: ...

The volume of the Earth's glaciers is 150,000 km3: estimates and map of the AI ​​IceBoost v.2.0 model

The volume of the Earth’s glaciers is 150,000 km3: estimates and map of the AI ​​IceBoost v.2.0 model

The distribution of glaciers in the IceBoost 2.0 model. A team of Italian researchers has developed a new Artificial Intelligence model, called IceBoost v.2.0to reconstruct the volume and distribution of glaciers on the planet, excluding the polar ice caps. From the model, trained with over 7 million thickness measurements of iceit turned out that overall the planet’s glaciers (excluding the ...

A humpback whale dives into the waters of the Arctic Circle. Credit: Timo Heinz for HX Expeditions. Some of the largest whales in the world, including humpback whales, minke whales and fin whalesare increasingly present in the coastal waters of Greenland eastern. These are areas which until a few decades ago were largely inaccessible to these cetaceans due to sea ...

From the Parks railway to the Monferrato railway, 13 lines of historic trains that travel for 1000 km

From the Parks railway to the Monferrato railway, 13 lines of historic trains that travel for 1000 km

From Piedmont to Friuli-Venezia Giulia and up to Sicily, in Italy there are 13 historic train lines born between the nineteenth and twentieth centuries on which we can still travel today to admire breathtaking views: previously abandoned, they have been recovered thanks to the project “Timeless tracks”, started in 2014 by the FS Italiane Foundation. These railway lines cross the ...

Anyone who calls for help without a reason will have to pay: the rules of the Guardia di Finanza and the price list

Image created with AI for illustrative purposes The rules for rescue interventions by the Financial Police have officially changed. From now on, anyone who deliberately or through gross imprudence causes an emergency situation, as well as who alerts rescuers without real necessity or justified reason, will be required to reimburse the costs. No generalized payment is being introduced, the Fiamme ...

Who is faster between the cheetah and the leopard and the differences in recognizing the two felines by their spots and physique

Who is faster between the cheetah and the leopard and the differences in recognizing the two felines by their spots and physique

Fast versus stealthy, lean versus rugged, polka dots versus rosettes. Cheetah (Acinonyx jubatus) and leopard (Panthera pardus), spotted cats of Africa, may seem similar from afar, but they actually hide profound realities both physical and ethological differences. The first is thefastest land animal in the worldcapable of touching the 100 km/h during its daytime hunting trips, with a thinner body, ...
