Better hearing with optical cochlear implants
Imaging techniques enable decisive step toward development of novel hearing prostheses In cochlear implants background noises compromise the comprehension of speech. The teams of Tobias Moser and Tim Salditt (both MBExC) were now able to use combined imaging techniques of X-ray tomography and fluorescence microscopy to create detailed images of

Better hearing with optical cochlear implants
Understanding spoken words, developing normal speech – cochlear implants enable people with profound hearing impairment to gain a great deal in terms of quality of life. However, background noises are problematic, they significantly compromise the comprehension of speech of people with cochlear implants. The team led by Tobias Moser from

Structure of human Mediator-RNA polymerase II pre-initiation complex
Authors Rengachari S, Schilbach S, Aibara S, Dienemann C, Cramer P Journal Nature Citation Nature 594, 129–133 (2021). Abstract Mediator is a conserved coactivator complex that enables the regulated initiation of transcription at eukaryotic genes1-3. Mediator is recruited by transcriptional activators and binds the pre-initiation complex (PIC) to stimulate the

Multiple Haplotype Reconstruction from Allele Frequency Data
Authors Pelizzola M, Behr M, Li H, Munk A, Futschik A Journal Nature Computational Science Citation Nat Comput Sci 1, 262–271 (2021). Abstract Because haplotype information is of widespread interest in biomedical applications, effort has been put into their reconstruction. Here, we propose an efficient method, called haploSep, that is

Cryo-electron tomography of native Drosophila tissues vitrified by plunge freezing
Authors Baeuerlein FJB, Pastor-Pareja JC, Fernandez-Busnadiego R Journal bioRxiv Citation bioRxiv 2021.04.14.437159. Abstract Cryo-focused ion beam (cryo-FIB) milling allows thinning vitrified cells for high resolution imaging by cryo-electron tomography (cryo-ET). However, it remains challenging to apply this workflow to tissues, as they usually require high-pressure freezing for vitrification. Here we
