Visualizing the multidimensional landscape of biological variation in modern microscopy

Authors Müller GF, Göpel T, Scherf N, Huisken J. Journal Frontiers in Bioinformatics Citation Front Bioinform. 2026 Mar 10;6:1757489. Abstract Variation is a foundational biological principle that has historically been marginalized-both due to limited experimental accessibility and because of idealized, stereotypic blueprints rooted in essentialist thinking. With the advent of

Image modifications reduce differences in natural-image encoding by retinal ganglion cells between natural and optogenetic stimulation

Authors Ramakrishna V, Gollisch T Journal BioRxiv Citation bioRxiv 2026.03.06.710066. Abstract Photoreceptor degeneration is among the leading causes of blindness and optogenetics as a potential therapeutic measure has garnered much attention over recent years. In this approach, light-sensitive molecules like Channelrhodopsin-2 (ChR2) are inserted into neurons in the retina to

Structural remodeling of the mitochondrial protein biogenesis machinery under proteostatic stress

Authors Ehses K, López-Alonso JP, Antico O, Azem A, Muqit MMK, Ubarretxena-Belandia I, Fernández-Busnadiego R Journal Science Advances Citation Sci Adv. 2026. Sci Adv. 2026 Mar 6;12(10):eaed3579. Abstract Cells have evolved organelle-specific responses to maintain protein homeostasis (proteostasis). During proteostatic stress, mitochondria down-regulate translation and enhance protein folding, yet the

A transition-prone brain state precedes spontaneous behavioral switching

Authors Wanken P, Edelman BJ, Behera L, Martinez de Paz JM, McCarthy PT, Macé E Journal BioRxiv Citation bioRxiv 2026.03.06.709845. Abstract Animals exhibit behavior in the absence of external stimuli or explicit tasks. Is the initiation of such spontaneous behavior shaped by internal brain states in a predictable manner? If

Mechanism of human tRNA 3′CCA maturation

Authors Kuhle B, Krebs L, Bhatta A, Dennerlein S, Rehling P, Hillen H Journal BioRxiv Citation bioRxiv 2026.03.02.709036. Abstract The non-templated addition of the 3′CCA end is the final universal step of tRNA maturation. In humans, 3′CCA addition on nuclear- (nu-tRNA) and mitochondria-encoded tRNAs (mt-tRNA) is catalyzed by a single
