Researchers have recently found a new way to summon useful structures in magnetic materials using light, heat, and electric fields. This new method, described in a new study published in Physical ...

DNA can assume a variety of secondary structures aside from the canonical B-form. Sequences capable of forming these alternative structures in vitro are often sites of genomic instability in vivo.

Organizations with hierarchical structures are easily graphed and defined. Often described as "tree structures," they are unambiguous and relatively permanent organizational models, in which each ...
