- In 2016, researchers restored 452 meters of Maryland's Muddy Creek with woodchips, sand and gravel. 2 years later, monitoring found suspended sediment fell 73.8%, improving stream functionMuddy Creek is a tributary of the Rhode River and flows through the Smithsonian Environmental Research Center, an important site for ecolog...
- In 2000, UC Irvine led a 2-season study of rice paddies, finding crops emit ozone-depleting gases. Years later, the research still shows rice farming contributes 5% of atmospheric methyl iodide globally todayRice paddies are known for methane emissions. But UC Irvine researchers found another atmospheric connection worth watching. Flooded rice f...
- In 2019, KAUST researcher modeled 1 insect cuticle to create gas-entrapping pores. 7 years later, clean water facilities deploy 2 distinct hydrophobic membranes to desalinate seawater cheaply without chemical wasteKAUST researchers found an unexpected answer in nature. They studied springtails and seaskaters that trap air around their bodies underwate...

- China's Geely used 800 engineers and AI to create a modular EV manufacturing system; Ford is now applying it in Spain, aiming to slash development time and costs by half without building the system itselfFor decades, Western automakers entered Chinese joint ventures primarily to secure access to local buyers. That dynamic has quietly inverte...
- In 2017, USGS and MIT researchers dated a magma pulse to 251.9 million years ago. 9 years later, it links to Earth's worst extinctionEarth faced its worst extinction event around 252 million years ago. Volcanic activity in the Siberian Traps is the leading explanation for...

- In 1972, Apollo 17 astronaut Jack Schmitt suddenly shouted, “There is orange soil!”: It contained tiny glass beads from ancient lunar fire fountainsDuring the Apollo 17 mission, astronauts stumbled upon intriguing orange soil at Shorty Crater, revealing a treasure trove of microscopic g...
- 12,000 years ago, Yellowstone’s dry summers began leaving a charcoal trail in its lakes. 6,000 years later, researchers found the same climate pattern linked to lower lake levels and reduced hydrothermal activityYellowstone lake sediments preserved ancient climate and environmental records. Warmer, drier summers between 12,000 and 6,000 years ago br...
- In 1945, Hiroshima’s atomic blast vaporized metal, glass, soil and water; 81 years later, scientists studying the cooled material found strange glass spheres that may preserve a never-before-seen alloyAfter decades of 1945 Hiroshima atomic bombing, scientists studying tiny glass particles found around Hiroshima Bay have identified evidenc...
- Massachusetts’ 2022 drought pushed seawater into a coastal marsh, triggering an 83% crash in methane emissions; the wetland still hadn’t recovered a year laterIn 2022, Massachusetts experienced a significant drought that led to seawater intrusion in a coastal marsh. This unusual phenomenon resulte...
