6+ hour, 21+ min ago   (324+ words) Mars may have built a surprisingly complex crust through large magmatic systems without the plate tectonics long thought necessary. To determine whether the boundary separated distinct rock types, the researchers used thermodynamic modeling and statistical methods to compare the seismic…...

1+ week, 5+ day ago   (251+ words) Stonehenge’s Altar Stone may have traveled south through a combination of glacial transport and deliberate human movement....

2+ week, 14+ hour ago   (387+ words) A German and Turkish research team is studying a shrinking glacier as a record of past climate and environmental change. More than 5,000 meters above sea level, amid intense cold, strong winds, and oxygen levels roughly half those in the valley…...

2+ week, 15+ hour ago   (1178+ words) A river can now move nearly a year’s worth of sediment in just a few intense weeks. Across the United States, the sand, silt, and soil carried downstream by rivers are becoming increasingly concentrated into short, intense bursts, according to…...

2+ week, 1+ day ago   (628+ words) A meteorite found in Algeria has opened a rare window into nearly 2 billion years of Mars' history that had largely been missing from the geological record....

2+ week, 2+ day ago   (378+ words) A tiny fossil overlooked for decades at La Brea Tar Pits has turned out to belong to a species previously unknown to science....

3+ week, 2+ day ago   (735+ words) By studying how seismic waves move through frozen soil on Earth, a geophysicist helped develop a more effective method for detecting water ice on the Moon. Beneath the Moon’s permanently shadowed polar craters, water ice may lie hidden beyond the…...

3+ week, 3+ day ago   (1348+ words) A stone analyzed at the Sirius particle accelerator supports the hypothesis that the mineral goethite can carry water from the planet’s surface into rocks in the lower mantle. A microscopic pocket sealed inside a diamond only 3 millimeters long may record…...

1+ mon, 2+ day ago   (486+ words) A fossil’s modern coordinates reveal where it was found, but not where that location sat millions of years ago as tectonic plates shifted across the planet. Reconstructing that ancient position is a demanding task in paleontology and related fields, especially…...

1+ mon, 1+ week ago   (928+ words) Earth may have been recycling surface water through its deep interior more than three billion years ago. In the Pilbara region of Western Australia, volcanic rocks more than three billion years old preserve traces of a journey once considered unlikely....
