Mitochondria are excitable organelles, and their electrophysiological activity across the inner mitochondrial membrane (IMM) plays a critical role in energy metabolism, cell signaling and cell fate regulation. While the transmembrane voltage of the IMM (Δψm) is traditionally measured with Nernstian dyes such as tetramethylrhodamine methyl ester (TMRM), here we introduce HBmito Crimson (HBmito), a novel membrane-anchored voltage sensor to probe mitochondrial near-field potential (Vnf) in intact cells by capturing fluorescence signal variations through rapid optical imaging. Vnf encompasses surface potential and the innermost portion of Δψm. During mitochondrial action potential, HBmito-reported Vnf-related signals show up to a 1.9-fold increase, concurrent with Δψm changes reported by TMRM. At an imaging rate of 1000 frames per second, transient miniature Vnf-related flickers were further revealed. And these events were three orders of magnitude smaller than action potentials and likely reflected the activity of individual mitochondrial ionic channels. These results provide the first optical imaging evidence of fundamental electrophysiological events in intact mitochondria, and highlight a novel approach for studying excitable membranes.

Photonix is a photo management application that solves a lot of problems. Once set up it will ingest all the photos in your collection and start building up an image database of everything you could want to search and filter by. It makes your entire collection available to you, whichever device you’re using — as long as you can get to a web browser.

Researchers say breakthrough could supercharge clean energy transition

Solar concentrators laterally converge solar energy to the side of architectural glass and are attractive candidates for building-integrated photovoltaics. Present available luminescent-type and scattering-type solar concentrators suffer from omnidirectional waveguide induced low efficiency, coloring/hazing restrained aesthetic quality, and poor compatibility with existing architectural glass. Here, we propose a diffractive solar concentrator via directly coating cholesteric liquid crystal (CLC) layers onto the architectural glass. The stacked CLC layers with submicron lateral periodic alignment enable broadband and unidirectional waveguiding inside the glass, and thus supply a high-efficient platform for transmissive solar energy capturing with merits of high aesthetic quality and economic viability. A 1-inch-diameter prototype powers a 10-mW fan outdoors, and a typical 2-m-wide window is calculated to concentrate solar energy by 50 times. The design is expected to bring a global terawatt-scale green energy supply and billion-ton annual carbon emission reduction, meeting with the sustainable development of human society.

Researchers have unveiled a groundbreaking advancement in the field of fluorescence microscopy, designed to resolve one of the most significant challenges facing scientists: image degradation due to noise in dynamic in vivo imaging. This innovative method, recently published in the journal PhotoniX, presents a self-supervised deep learning approach known as Temporal-gradient empowered Denoising (TeD). The newly developed technique stands to revolutionize the way researchers capture and analyze high-speed biological processes, which are often severely obscured by noise.
