The Authors use a double modulation of both excitation and emission light to correct aberration and demonstrate imaging through thick scattering tissue. The approach is noise-robust and can image weak fluorescent neurons inside a thick brain slice.
A non-common-path interferometric scheme enables holographic detection of single proteins of mass 90 kDa and estimation of single-protein polarizability.
A distance-based mapping strategy using single-molecule fluorescence resonance energy transfer via DNA eXchange (FRET X) enables full-length fingerprinting of intact protein sequences.
The ability to extract information from diffuse background signals in ultrafast electron diffraction experiments now enables a direct view of the formation of topological defects during a light-induced phase transition.
The antiferromagnetic material haematite, named for its blood-red colour, hosts swirling spin vortices termed merons. The rotation sense of such antiferromagnetic vortices has now been imaged in real space.
