In the words of sociologist Harkaitz Zubiri, it is currently accepted that social hierarchy is constructed of individual merits, but the reality is quite different. He thus rejects meritocracy.

The fifth dwarf planet of the Solar System, Haumea, and at least one of its two satellites, are covered in crystalline water-ice due to the tidal forces between them and the heat of radiogenic elements. This is the finding of an international research study using observations from the VLT telescope at the European Southern Observatory in Chile. The tiny and strange planet Haumea moves beyond the orbit of Neptune. It has the shape of a flattened rugby ball and is around 2,000 km long. It spins...

Mediterranean landscapes have undergone great change in recent decades, but species have adapted to this, at least in the case of roe deer, Spanish ibex, red deer and wild boar. This has been shown by Spanish researchers who have analyzed the effects of changes in land use on the past, present and future distribution of these species. "In the last few decades there has been an increase in the area of distribution of wild ungulates", explains Pelayo Acevedo, lead author of the study and...

"Although there are no seals in Spanish waters, these species can be used as biomonitors of global pollution", Octavio P©rez Luzardo, one of the authors of the study...
