    The researchers showcase swept-coded aperture real-time femtophotography—an all-optical single-shot computational imaging modality at up to 156.3 trillion frames per second—video-records transient absorption in a semiconductor and ultrafast demagnetization of a metal alloy.

    In the Bloch or Neel domain walls in ferromagnets, the magnetization rotates smoothly from up to down, preserving its magnitude. Here, Lee et al show that Co3Sn2S2 exhibits a phase transition within its domain walls to a state in which the magnetization passes through zero rather than rotating as the wall is traversed.

    Molecular orientation is often ignored during single-molecule localisation microscopy. Here, the authors use a Vortex point spread function in order to simultaneously estimate the 3D position, dipole orientation and degree of rotational constraint, within 30% of the Cramér-Rao bound limit.

    The authors have recently developed molecular force microscopy (MFM) which uses fluorescence polarisation to measure cell-surface receptor force orientation. Here they show that structured illumination microscopes, which inherently use fluorescence polarisation, can be used for MFM in a turn-key manner.

    Determining the orientation of single molecules in super resolution imaging is challenging. Here, by adding polarization control to phase control in the Fourier plane of the imaging path, parameters such as 3D spatial position, 3D orientation and wobbling or dithering angle can be determined from single molecules.

    Polarization microscopy has been combined with single-molecule localization, but it’s often limited in either speed or resolution. Here the authors present polarized Structured Illumination Microscopy (pSIM), a method that uses polarized laser excitation to measure dye orientation during fast super-resolution live cell imaging.

    Integrin αβ heterodimer cell surface receptors mediate adhesive interactions that provide traction for cell migration. Here the authors show that actin flow can orient cell surface integrins during leukocyte migration, suggesting integrin activation by cytoskeletal force.
