Nitrogen Needs Could Be Limiting Nature’s Carbon Capacity
A new study suggests that past calculations of biological nitrogen fixation were overestimated by up to 66%—and that farms growing nitrogen-fixing crops may be filling in the gaps, for better or worse.
Video Shows Pulsing and Curving Fault Behavior
A chance video captured a fault rupture during March’s devastating Myanmar earthquake, delivering real-time evidence of how major seismic tremors propagate.
Infrared Instruments Could Spot Exotic Ice on Other Worlds
Phases of ice that exist naturally only on frozen moons could be detected using infrared spectroscopy, according to new laboratory experiments.
El queso en tiempos de la agricultura industrial y el cambio climático
Los pastizales y la dieta de las vacas están cambiando a medida que se calienta el clima, pero un experimento agrícola en Francia revela la importancia de proporcionar pastos a las vacas.
Blame It on the BLOBs
For decades, scientists have suspected that large volcanic eruptions have their origins in two mysterious massive regions at the base of our planet’s mantle. Now, it’s been statistically proven.
Parts of New Orleans Are Sinking
Areas near the airport, along floodwalls, and in nearby wetlands are subsiding because of a combination of natural and anthropogenic forces.
Arctic Ice Shelf Theory Challenged by Ancient Algae
Chemical signatures of marine organisms reveal that seasonal sea ice, not a massive ice shelf, persisted in the southern Arctic Ocean for 750,000 years.
Residents Know When Floods Happen, But Data Must Catch Up
Federal flood measurements often don’t match what people see in their communities. Scientists have created a hyperlocal solution.
Coral Cores Pinpoint Onset of Industrial Deforestation
Trace elements in coral reefs provide a timeline of how Borneo’s rainforests have been altered by industry.
