Using the Advanced Photon Source, scientists have recreated the structure of ice formed at the center of planets like Neptune and Uranus. Everyone knows about ice, liquid and vapor — but, depending on the conditions, water can actually form more...
Everyone knows about ice, liquid and vapor — but, depending on the conditions, water can actually form more than a dozen different structures. Scientists have now added a new phase to the list: superionic ice. This type of ice forms at extremely...
(Inside Science) -- Next time you’re about to bite into an apple, slice it open first and inspect its cross-section. If you look in the right spot, you’ll observe that the stem cavity -- where the surface dips down to meet the stem -- is so sharply sloped it nearly becomes a vertical line. Here the curvature, the local change in slope, is what mathematicians would call “singular.” Singularities show up in a large range of physical systems, from light reflecting in tea cups to black holes that warp space-time.
