A long stretch of humid heat followed by intense thunderstorms is a weather pattern historically seen mostly in and around the tropics. But climate change is making humid heat waves and extreme storms more common in traditionally temperate midlatitude regions such as the midwestern U.S., which has seen episodes of unusuallyContinue Reading

NASA teams have completed filling the core stage of the SLS (Space Launch System) rocket with liquid hydrogen and transitioned to topping mode. Topping ensures the tank reaches its full capacity with super-cold liquid hydrogen chilled to minus 423 degrees Fahrenheit. Engineers continue to watch the leak at the interfaceContinue Reading
Older buildings let thousands of dollars-worth of energy go to waste each year through leaky roofs, old windows, and insufficient insulation. But even as building owners face mounting pressure to comply with stricter energy codes, making smart decisions about how to invest in efficiency is a major challenge. Lamarr.AI, bornContinue Reading

As demand for critical metals grows, scientists have taken a rare, close look at life on the deep Pacific seabed where mining may soon begin. Over five years and 160 days at sea, researchers documented nearly 800 species, many previously unknown. Test mining reduced animal abundance and diversity significantly, thoughContinue Reading
