For instance, it can help scientists measure ocean acidification or other threats increased carbon levels pose to aquatic ecosystems. But one major, and often…

Animations created by NASA’s Scientific Visualization Studio include images and videos showing what carbon emissions would look like if they were visible in our atmosphere. The videos of the swirling emissions were released this month—and it looks like a grosser, creepier version of the Northern Lights.Prime Day Ain't That 'Green'The visuals are recreated from 2021 carbon dioxide emissions data, according to NASA. They’re shown as swirls all over the planet and how those emissions progressed from the beginning of 2021 to…

Microplastics naturally scatter in flowing water (left), but after turning on sound waves, the particles concentrate along the tube’s sides (right), making them easier to remove. Credit: Menake PiyasenaMicroplastic particles, less than 5 mm wide, pose potential harm to aquatic life and humans as they pervade waterways worldwide. Researchers have developed a two-stage device using steel tubes and pulsing sound waves to effectively remove most plastic particles from water samples. The team will present their results at the…

This story originally appeared on High Country News and is part of the Climate Desk collaboration.Dozens of once crystal-clear streams and rivers in Arctic Alaska are now running bright orange and cloudy, and in some cases they are becoming more acidic. This otherwise undeveloped landscape now looks as if an industrial mine has been in operation for decades, and scientists want to know why.Roman Dial, a professor of biology and mathematics at Alaska Pacific University, first noticed the stark water-quality changes while…

I know a lot of people think of deserts as big, empty, lifeless wastelands — that’s one of the reasons it can be tough to get folks to care about protecting them. But when I moved to Southern California from New England, my desert enchantment was immediate and deep.One of the things that struck me most about exploring the deserts here was that the slower I went, the more I saw. Sure, if you’re speeding to Vegas on the 15, the Mojave is going to seem pretty nondescript and forgettable. But on foot, you notice the intricate…

After being introduced to Russia's White Sea in the 1950s, non-native Pacific salmon have since spread along Norway's coastline and into its rivers. In an effort to control their numbers, an AI-enabled fish-identifying gate has recently been installed on a Norwegian river.Besides introducing new diseases to native Atlantic salmon, the invasive Pacific salmon also have a faster reproductive cycle. This means that as their numbers have more quickly increased, they've start outcompeting Atlantic salmon for food and spawning…
