Dinosaurs may have lived in social herds as early as 193 million years ago
Fossils indicate a communal nesting ground and adults who foraged and took care of the young as a herd, scientists say.
Rover images confirm Jezero crater is an ancient Martian lake
The findings include signs of flash flooding that carried huge boulders downstream into the lakebed.
3 Questions: Understanding the Haiti earthquakes
Assistant professors Camilla Cattania and William Frank discuss the science behind the 2010 and 2021 earthquakes in Haiti.
Professor Emeritus Frederick Frey, a leader in the field of geochemistry, dies at 83
Over a career spanning five decades, Frey pioneered the use of new techniques to study the Earth’s mantle.
Zeroing in on the origins of Earth’s “single most important evolutionary innovation”
A new study shows oxygenic photosynthesis likely evolved between 3.4 and 2.9 billion years ago.
Taylor Perron receives 2021 MacArthur Fellowship
In his research, the geomorphologist seeks connections among landscape evolution, biodiversity, and human history.
Geologists take Earth’s inner temperature using erupted sea glass
The results could help scientists unravel the processes underlying plate tectonics.
A new approach to preventing human-induced earthquakes
Applied in the field, a new model reduced quakes from oil and gas processes; could help manage seismic events from carbon sequestration.
Study highlights long road toward gender parity in the geosciences
Researchers find improvement in relative retention of women but predict decades of sustained effort are required to achieve gender parity.
Cave deposits show surprising shift in permafrost over the last 400,000 years
Study finds Earth’s frozen surfaces became less susceptible to thawing, potentially locking in more carbon than expected.
Ancient atmospheric oxygen sleuthing with ocean chromium
Findings show how the trace metal is chemically altered in the anoxic, modern ocean and provide the basis for investigating paleorecords of atmosphere composition shifts.
With Perseverance, MIT teams prepare for Mars rover landing
Following touchdown, MOXIE will brew up oxygen while geologists comb for sediments to sample.
Geologists produce new timeline of Earth’s Paleozoic climate changes
The record shows ancient temperature variations coinciding with shifts in the planet’s biodiversity.
Professor Emeritus Peter Eagleson, pioneering hydrologist, dies at 92
Former Department of Civil and Environmental Engineering head and AGU president revolutionized thinking about the global water cycle, raising it to a place of prominence in the geosciences, and inspiring generations of students.
Rock magnetism uncrumples the Himalayas’ complex collision zone
MIT EAPS researchers find the impressive mountain range formed over a series of impacts, not a single event, as previously thought.
