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
