The Inside View

Inside view.

Intravascular ultrasound: an inside view.

Bifurcation lesions: an inside view.

Listening to dodecaphonic music requires patience and a willingness to be prepared to study the same piece over and over again. We experienced a similar feeling after reading 2 important studies about bifurcation lesions featured in this issue of Circulation: Cardiovascular Interventions. The first read gives a general impression; however, understanding and appreciation only comes after reading...

An Inside-out View of Bubbles

Fast stellar winds can sweep up ambient media and form bubbles. The evolution of a bubble is largely controlled by the content and physical conditions of the shocked fast wind in its interior. This hot gas was not clearly observed until the recent advent of Chandra and XMM-Newton X-ray observatories. To date, diffuse X-ray emission has been unambiguously detected from two circumstellar bubbles ...

An Inside View of Magnetic Skyrmions

A magnetic skyrmion is the smallest possible perturbation to a uniform magnet: a pointlike region of reversed magnetization, surrounded by a whirling twist of spins. Such skyrmions are quasiparticles—they do not exist in the absence of a magnetic state–and they give rise to emergent electrodynamics that cannot be simply described by Maxwell’s equations. The particles are also attractive candida...
