Blocking infinity in a topological insulator

(Phys.org)—In bulk, topological insulators (TIs) are good insulators, but on their surface they act as metals, with a twist: the spin and direction of electrons moving across the surface of a TI are locked together. TIs ...

Moving microscopic vision into another new dimension

Scientists who pioneered a revolutionary 3-D microscope technique are now describing an extension of that technology into a new dimension that promises sweeping applications in medicine, biological research, and development ...

Physicists discover surprising variation in superconductors

(PhysOrg.com) -- MIT physicists have discovered that several high-temperature superconductors display patchwork quilt-like variations at the atomic scale, a surprising finding that could help scientists understand a new class ...

Giant nanomachine aids the immune system

Cells that are infected by a virus or carry a carcinogenic mutation, for example, produce proteins foreign to the body. Antigenic peptides resulting from the degradation of these exogenous proteins inside the cell are loaded ...
