Trees Wearing Accelerometers Help Track Snowstorms
This device allows scientists to measure how much snow is trapped in canopies and predict changes to snowpack—a critical factor in annual water availability.
Lightning Had Difficulty Forming in Early Earth’s Atmosphere
Lightning could have sparked the beginnings of life, but the primordial atmosphere might have made it more difficult for lightning to initiate.
Western U.S. “Megafloods” Might Not Have Been So Mega
The flooding that carved eastern Washington State 20,000 to 12,000 years ago could have been 80% smaller than the canyons’ volume today.
How Climate Change Shaped the Amazon’s Land and Life
Ice Age climate swings shaped the equatorial basin’s terrain—and possibly its ecology—faster than previously thought.
Cyanobacteria Blooms Exceed WHO Thresholds in Midwest Lakes
A study of 369 lakes across the Midwest finds that many of them, especially those close to agriculture, have high concentrations of harmful algal bloom-causing cyanobacteria.
Wind and Ocean Currents May Contribute to Mass Dolphin Strandings
Coastal wind patterns correlate with mass strandings of dolphins, suggesting that storm-induced upwelling could be influencing cetaceans’ behavior.
Remote Work May Be Keeping Some Cities’ Air Cleaner
Widespread remote work may have kept air pollution lower than pre-COVID-19 lockdown levels even though restrictions were lifted in 2020, a new study finds.
Extinct Style of Plate Tectonics Explains Early Earth’s Flat Mountains
The geologic record suggests that despite Earth’s hot, thin crust during the Proterozoic, mountains were still able to form thanks to an extinct style of crustal deformation.
Cool Oasis for Cretaceous Feathered Dinosaurs
A new study found that the Jehol Biota had chilly temperatures and high altitudes when feathered dinosaurs roamed the slopes.
