A crowd beats the heat with spray from a fire hydrant in Seattle. A new method for measuring urban heat exposure shows that more densely populated neighborhoods may face higher heat and longer hot ...

Laboratory earthquakes shed new light on energy partitioning during earthquakes, which is allocated to seismic radiation, creation of new surfaces, and heat dissipation.

NASA’s Juno spacecraft snapped this image of Jupiter’s moon Ganymede in 2021. New experiments might help scientists identify exotic forms of ice present in ...

Despite warnings that their actions are illegal, Duffy and other senior NASA officials have continued to secretly direct NASA employees to draw up plans to end at least two major satellites missions ...

Around 1.1 billion years ago, the oldest and most tectonically stable part of North America—called Laurentia—was rapidly heading south toward the equator. Laurentia eventually slammed into Earth’s ...

A schematic of the Pi Cloud Chamber. Scientists created a “cloud-in-a-box,” where warm, humid air from the heated bottom wall meets cooler, humid air from the cold top wall, generating supersaturation ...

The 2025 Palisades and Eaton Fires torched scrub-lined slopes of the San Gabriel and Santa Monica Mountains, as well as buildings, streets, cars, and infrastructure. Before the flames were even ...

Heat waves, such as the record-breaking Siberian heat wave in 2020, are having lingering impacts on Arctic ecosystems. Credit: Andrei Zverev/Flickr, CC BY-NC 2.0 Now Kwon et al. suggest that the ...

The prevailing view of mammal activity in ecosystems is that they have marginal impacts to services like greenhouse gas emissions. However, that is not always the case, especially with large, feral ...

Using paleomagnetic samples collected along the shores of Lake Superior, a new study illuminates the movement of a billion-year-old paleocontinent as it crept south toward a tectonic collision.

As multiple fires raged through Los Angeles in January 2025, Bernadeth Tolentino had one more thing to worry about: kelp. Tolentino, a marine biologist and graduate student at the University of ...
