This valuable study presents a technically sophisticated intravital two-photon calcium imaging approach to characterize Ca²⁺ dynamics in distinct populations of meningeal macrophages in awake, freely ...

Attempts to break the diffraction limit with 'super lenses' have all hit the hurdle of extreme visual losses. Now physicists have shown a new pathway to achieve superlensing with minimal losses, ...

Transmission electron microscopes (TEMs) have been advancing our knowledge of the very small for nearly 100 years. Since their advent, they have helped scientists see structures as small as individual ...
