ND Expert Julia Adeney Thomas: The reality of the Anthropocene

University of Notre Dame — Mon, 26 Aug 2024 11:05:46 EST

For the last seven decades, Earth has been operating in unprecedented ways, leading many researchers to argue that we have entered a new geological epoch known as the Anthropocene."While it may not have been formally accepted onto the geological time scale, the Anthropocene is real and its effects have drastically and irrevocably changed the living conditions on our planet," said Julia Adeney Thomas, a professor of history at the University of Notre Dame.

Matching dinosaur footprints found on opposite sides of the Atlantic Ocean

Southern Methodist University — Sun, 25 Aug 2024 23:55:00 EST

An international team led by SMU paleontologist Louis L. Jacobs has found matching sets of Early Cretaceous dinosaur footprints on what are now two different continents. In terms of their geological and tectonic plates contexts, these dinosaur fossils were found to be almost identical.

Mapping the invisible: how sub-daily GPS sheds light on early postseismic deformation

Chinese Academy of Sciences — Mon, 05 Aug 2024 08:05:55 EST

A pioneering study has unlocked new insights into the immediate behavior of the Earth's crust following earthquakes. By applying sub-daily Global Positioning System (GPS) solutions, researchers have precisely measured the spatial and temporal evolution of early afterslip following the 2010 Mw 8.8 Maule earthquake. This innovative approach represents a significant advancement in seismic analysis, providing a more accurate and rapid depiction of ground deformations that are crucial for assessing seismic hazards and understanding fault line activities.

DART Forward: Five Papers Shed New Light on Asteroids From World's First Planetary Defense Test
