In classical mechanics, particles are represented by point masses or rigid bodies, and in field theory by wave-like excitations or vibrations. Magnetic skyrmions are small, vortex-like spin textures of topological origin ...
Electrons tend to avoid one another as they go about their business carrying current. But certain devices, cooled to near zero temperature, can coax these loner particles out of their shells. In extreme cases, electrons will ...

DNA is a lengthy molecule—approximately 1,000-fold longer than the cell in which it resides—so it can't be jammed in haphazardly. Rather, it must be neatly organized so proteins involved in critical processes can access ...
