In 2010, the marine ecologist Peter Stevick, from the College of the Atlantic, reported in a study published in the journal Biology letters the case of a humpback whale (Megaptera novaeangliae) that traveled 9,800 km, between the coast of Brazil and Madagascar.

A curious study that has just been published in Geophysical Research Letters warns about some "evildoers" that are not considered when we talk about climate change: the gases used to anesthetize patients during operations.

It's not just climate change that endangers the survival of the polar bear (Ursus maritimus), one of the largest and most threatened carnivorous mammals on the planet.

A team of paleontologists from the University of Zurich, in Switzerland, in collaboration with experts in primitive fauna from different Chinese and European institutions, has discovered in the Helvetian site of Monte San Giorgio two new species of Saurichthys, extinct prehistoric fish that lived in the Triassic period, between 250 and 200 million years ago.

Despite what it may seem, the blue planet is becoming greener, according to an international study based on data collected by satellites over twenty years.

There are some animal species with a characteristic blue, purple or lavender colored tongue that makes them particularly special. Among them are the blue-tongue lizard, the Chow Chow dog or the black bear. But why do their tongues have such a striking and irregular bluish color?

It is not uncommon to observe this type of horizontal clouds guarding the tops of the mountains, because their formation is associated with the orography of the terrain.

One of the most important climatic phenomena on the planet, the Gulf of Mexico Stream, which warms temperatures in Western and Northern Europe and makes the climate more moderate in those northern latitudes, has slowed in recent decades, with the As a result, its effects have been weaker than ever, at least in the last millennium.
