- 			 Climate ClimateAs wildfires worsen, science can help communities avoid destructionBlazes sparked in wild lands are devastating communities worldwide. The only way to protect them, researchers say, is to re-engineer them. 
- 			 Materials Science Materials ScienceSalt can turn frozen water into a weak power sourceExperiments reveal that when slabs of salty ice are strained, electricity is generated, though practical uses are still a long way off. 
- 			 Earth EarthUseful metals get unearthed in U.S. mines, then they’re tossedRecovering these metals from mining by-products destined for waste sites could offset the need to import them from elsewhere or open new mines. 
- 			EnvironmentSee how aerosols loft through Earth’s skyAerosols, small particles in the atmosphere like salt and dust, may offset a third of human-caused climate warming, though their influence is fading. 
- 			PaleontologyA new species of ‘penis worm’ was discovered in the Grand CanyonA trove of fossils, including a penis worm with a spiked, invertible throat, suggests this spot may have been a cradle of Cambrian evolution. 
- 			 Earth EarthWhy devastating tsunamis didn’t follow the Russia earthquakeGeologists unpack why the magnitude 8.8 temblor — the sixth largest ever recorded — fomented waves that reached Japan and Hawaii but caused little damage. 
- 			 Climate ClimateHarmful heat doesn’t always come in wavesEven without reaching heat wave levels, sustained high temperatures may contribute to a litany of health issues. 
- 			 Earth EarthSmall earthquakes can have a big impact on the movements of major faultsSmall and far-off earthquakes can stifle the spread of large motions on some of the world’s biggest faults. 
- 			 Astronomy AstronomyA dwarf galaxy just might upend the Milky Way’s predicted demiseThe Milky Way may merge with the Large Magellanic Cloud in 2 billion years, not Andromeda, contrary to previous findings. 
- 			 Planetary Science Planetary ScienceVenus’ tectonics may be actively reshaping its surfaceCircular landforms speckling the Venusian surface may be the work of tectonic activity. 
- 			 Space SpacePerseverance takes the first picture of a visible Martian auroraA faint yet visible Martian aurora is the first instance of the phenomenon spotted from another planet's surface. 
- 			 Environment EnvironmentSkyborne specks of life may influence rainfall patternsA study of weather on a mountain in Greece reveal that bioparticles in the sky may drive fluctuations in rainfall patterns more broadly.
