A Exportação Ilegal de Fósseis É Mais do que um Irritante para o Sul Global
Mais de 2 mil pesquisadores assinaram carta aberta solicitando a repatriação do fóssil de um dinossauro para o Brasil. Alguns dizem que o caso destaca um padrão de colonialismo científico na paleontologia.
The End of the Eclipse
Scientists are studying how the Earth–Moon distance has changed over time, and what effect that change might have had on our planet. Future changes will extinguish total solar eclipses entirely.
Submarine Avalanche Deposits Hold Clues to Past Earthquakes
Scientists are making progress on illuminating how undersea sedimentary deposits called turbidites form and on reconstructing the complex histories they record. But it’s not an easy task.
Snapping Science in the Field
Snapchat, the multimedia messaging app, offers a range of features that make it an unexpectedly useful tool for geoscientists on the go.
Water Corridors Helped Homo sapiens Disperse out of Africa
Wetland conditions during the last interglacial period in parts of the Levant helped propel our ancestors into Arabia, new research suggests.
Ultra-High-Resolution Age Model in Clams Yields Daily Paleo-Data
Using geochemical techniques, scientists identify daily cycles in fossilized giant clams, which permits climate reconstructions at the weather timescale.
La exportación ilegal de fósiles es más que un Irritator para el Sur Global
Más de 2,000 investigadores han firmado una carta abierta solicitando la repatriación del fósil de dinosaurio a Brasil. Algunos afirman que el caso pone de manifiesto un modelo de colonialismo científico en la paleontología.
Shifts in Tectonic Plates Change Biodiversity
A 36-million-year cycle of marine biodiversity booms and busts matches the movements of plate tectonics, linking what happens deep below the ocean to what’s happening in it.
Illegal Fossil Export Is More Than an Irritator to the Global South
More than 2,000 researchers have signed an open letter requesting the repatriation of a dinosaur fossil to Brazil. Some say the case highlights a pattern of scientific colonialism in paleontology.
