U.S. Public Water Supply Is a Local Source of Phosphorus Pollution
Excess phosphorus may reach U.S. rivers, lakes, and groundwater through water main leaks and outdoor water use.
Rivers in the Sky Are Hindering Winter Arctic Sea Ice Recovery
Climate change is increasing the frequency of moisture-dumping atmospheric rivers in the Arctic. The storms are pushing back sea ice at a time of year when it should be expanding.
Prospecting for Copper with Machine Learning and Zircons
Using artificial intelligence, researchers can now identify zircons derived from valuable copper deposits.
UV Radiation Contributed to Earth’s Biggest Mass Extinction
To find the first direct evidence of heightened UV radiation during the end-Permian mass extinction, researchers turned to chemical evidence preserved in pollen grains.
How to Build a Climate-Resilient Water Supply
Scientists developed a new model to help water utility companies minimize weather-based disruptions to clean water access.
El agua subterránea se repone mucho más rápido de lo que pensaban los científicos
Un nuevo modelo basado en el clima indica que los científicos podrían haber subestimado la importancia del agua subterránea para mantener los ríos y la vida vegetal.
Groundwater Replenishes Much Faster Than Scientists Previously Thought
A new climate-based model indicates that scientists may be underestimating groundwater’s importance in sustaining streams and plant life.
Powerful Impact Provides Insight into Deep Structure of Mars
Seismic signals detected by the InSight lander show that the planet’s lower mantle may be less homogenous than previous models have suggested.
A Close Look at Melting Below Antarctica’s Largest Ice Shelf
Radar data reveal where, when, and how fast the base of the Filchner-Ronne Ice Shelf has been losing mass in recent years.
