Europa’s hidden ocean has made the icy moon one of the solar system’s most promising places to search for habitable conditions。 Scientists have hoped that water from this deep ocean might rise through cracks and form shallow reservoirs that future spacecraft could more easily study。 New simulations suggest that journey is unlikely because turbulent
A new 3D printing technique can produce exceptionally hard tungsten carbide cobalt while using less of its expensive raw materials。 By softening rather than fully melting the material, researchers created defect-free samples with industrial-grade hardness and opened the door to more efficient manufacturing
Ultrafast X-rays revealed how a molecule converts absorbed light into motion in just trillionths of a second。 Individual atoms recorded different stages of the process, opening a powerful new window into light-driven chemistry
Global warming appears to have shifted into a faster gear。 After removing the effects of El Niño, volcanic eruptions, and solar cycles, researchers found that the planet has warmed at roughly 0。35°C per decade over the past ten years, compared with just under 0
Fossilized dinosaur bones from Wyoming are offering a rare glimpse into the feeding behavior of Tyrannosaurus rex。 Researchers examined more than 3,000 bones dating back 72 to 66 million years and found just 12 with possible tooth traces, including four with patterns that closely matched the shape and spacing of T
