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.
3 Questions: Understanding the Haiti earthquakes
Assistant professors Camilla Cattania and William Frank discuss the science behind the 2010 and 2021 earthquakes in Haiti.
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.
Study: Global cancer risk from burning organic matter comes from unregulated chemicals
The researchers hope scientists and regulators will consider a broader class of compounds in evaluating cancer risk due to PAH exposure.
Global warming begets more warming, new paleoclimate study finds
Researchers observe a “warming bias” over the past 66 million years that may return if ice sheets disappear.
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.
How a sudden stratospheric warming affected the Northern Hemisphere
Research from MIT Haystack Observatory finds a stratospheric warming event over Antarctica linked to anomalies in near-Earth space above North America and Europe.
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.
Pathfinder satellite paves way for constellation of tropical-storm observers
Lincoln Laboratory’s TROPICS satellites will help scientists study extreme tropical weather once all six are launched next year.
New approach could change how we track extreme air pollution events
Study demonstrates the power of low-cost air quality sensors during volcanic eruption.
Imagining the distant past — and finding keys to the future
Associate professor of earth science David McGee studies the atmosphere’s response to paleoclimate changes.
Susan Solomon, scholar of atmospheric chemistry and environmental policy, delivers Killian Lecture
MIT professor describes her path to the Institute, her work on ozone depletion, and her insights on the state of climate policy.
Ozone-depleting chemicals may spend less time in the atmosphere than previously thought
New results point to unexpected, illegal production of several CFCs in recent years.
Tackling air pollution in India and the developing world
PhD student Sidhant Pai works on atmospheric chemistry models that may help policymakers improve air quality in their region.
