A team of paleontologists has discovered on King George Island, in the South Shetland Islands, the first fossil footprint unequivocally attributable to a terrestrial mammal in the Eocene of Antarctica. It is a specimen barely two centimeters long, preserved as a natural mold in fine-grained volcanic sediment, providing direct evidence of the presence of a […]

Un equipo de paleontólogos ha descubierto en la isla Rey Jorge, en las Shetland del Sur, la primera huella fósil inequívocamente atribuible a un mamífero terrestre en el Eoceno de la Antártida. Se trata de un ejemplar de apenas dos centímetros de longitud, conservado como un molde natural en un sedimento volcánico de grano fino, […]

Durante casi dos siglos, los arqueólogos que excavaron en Nimrud, una de las capitales del Imperio Asirio en el actual norte de Irak, centraron su atención en la colina de la acrópolis. Allí desenterraron palacios, templos y enormes relieves de piedra que narraban las hazañas de los reyes. Pero la ciudad que se extendía a […]

El observatorio de materia oscura más sensible del mundo, el experimento LUX-ZEPLIN (LZ), ha detectado una interacción de partículas que no logra ser explicada por los modelos convencionales de radiación de fondo, un hallazgo que, aunque aún está lejos de confirmarse como un descubrimiento definitivo, ha despertado un cauteloso optimismo en la comunidad científica internacional. […]

Hay monumentos antiguos que impresionan por su tamaño y otros que impresionan por su exactitud. El pozo sagrado de Santa Cristina, en el municipio de Paulilatino, provincia de Oristano en Cerdeña, pertenece al segundo grupo. Sus piedras de basalto están talladas y ensambladas con tal precisión geométrica que, según cuenta el propio centro que gestiona […]

For nearly two centuries, archaeologists excavating Nimrud, one of the capitals of the Assyrian Empire in present-day northern Iraq, focused their attention on the acropolis mound. There, they unearthed palaces, temples, and massive stone reliefs depicting the deeds of kings. But the city that spread at its feet—an extensive area of 340 hectares surrounded by […]

It is clear that ethnic differences, like religious ones, have been the origin of countless conflicts throughout the world from Antiquity to the present day. It is not surprising, then, that this also occurred when the Old and New Worlds established definitive contact after Columbus’s arrival in 1492. These differences manifested in Spanish America through […]

The world’s most sensitive dark matter observatory, the LUX-ZEPLIN (LZ) experiment, has detected a particle interaction that cannot be explained by conventional background radiation models, a finding that, although still far from being confirmed as a definitive discovery, has sparked cautious optimism in the international scientific community. The event, recorded nearly a mile underground at […]

There are ancient monuments that impress with their size and others that impress with their precision. The Sacred Well of Santa Cristina, in the municipality of Paulilatino, province of Oristano in Sardinia, belongs to the second group. Its basalt stones are carved and assembled with such geometric precision that, according to the site management center […]
