Exotic phases of matter known as spin ices are defined by frustrated spins that obey local "ice rules"—similar to electric dipoles in water ice. Physicists can define ice rules in two-dimensions for in-plane Ising-like ...
(Phys.org) —Normally, the strength of a magnetic field increases as you get closer to a magnet and decreases as you move further away—a concept easily understood when placing magnets near a refrigerator, for instance. ...
(Phys.org) —Scientists have many tools for measuring the cosmic structures of the universe, which includes structures such as galaxies, galaxy clusters, and intergalactic gas. Cosmic structures can be observed directly, ...
(Phys.org) —Sometimes mathematical theories have implications that extend far beyond their original purpose. This situation holds true for the four-color theorem, which was originally used by cartographers hundreds of years ...
Hopfions, magnetic spin structures predicted decades ago, have become a hot and challenging research topic in recent years. In a study published in Nature, the first experimental evidence is presented by a Swedish-German-Chinese ...

Animal cells get their structural integrity from their cytoskeleton, a shapeshifting mesh of filaments inside a cell that helps the cell organize its structure and communicate with its environment. A few years ago, scientists ...
