• This German submarine sank in 1917. It’s still leaking TNT

  A World War I submarine wreck off Denmark is leaking TNT into the surrounding water, seabed, and marine life more than a century after it sank. Scientists warn that thousands of similar wrecks could pose growing environmental risks as they continue to corrode.

• Crocodiles are famous for finding their way home. These ones didn’t

  Captive-raised saltwater crocodiles released into Bangladesh’s Sundarbans surprised scientists by settling into the wild rather than trying to return to their breeding facility. The result suggests that releasing larger, mature captive crocodiles could help restore depleted populations more successfully than relying only on vulnerable hatchlings.

• One Mount Etna eruption took weeks. Another happened in hours

  Mount Etna’s ancient eruptions followed radically different paths, with some magma lingering near the surface for weeks while other magma raced upward from nearly 30 kilometers deep in just hours. Scientists traced the difference to volcanic gases such as carbon dioxide and water, offering a powerful new way to understand and potentially anticipate explosive eruptions.

• Back-to-back Arctic storms can double sea ice loss

  Scientists have found that Arctic cyclones become especially destructive when several strike one after another. These storm clusters cause about twice as much sea ice loss as isolated cyclones, with impacts that persist roughly two and a half times longer. As Arctic ice becomes thinner and weaker, the damage from these storms appears to be increasing, potentially creating a feedback loop that accelerates future ice loss.

• NASA-backed scientists turn plastic waste into edible cookies

  Scientists have engineered yeast to turn PET plastic and agricultural waste into ingredients for protein-rich, 3D-printed cookies called µBites. Developed partly for NASA’s Deep Space Food Challenge, the system can produce proteins, fats, vitamins, and even vanilla flavoring from waste materials. Researchers hope the unusual technology could eventually help address both plastic pollution and food insecurity, while also supplying food in extreme environments such as deep-space missions.
