Turbulent molecular clouds [PDF]
, 2012 Stars form within molecular clouds but our understanding of this fundamental process remains hampered by the complexity of the physics that drives their evolution. We review our observational and theoretical knowledge of molecular clouds trying to confront the two approaches wherever possible.

Galaxy chemical evolution models: The role of molecular gas formation [PDF]
, 2017 In our grid of multiphase chemical evolution models (Moll\'a & D\'iaz, 2005), star formation in the disk occurs in two steps: first, molecular gas forms, and then stars are created by cloud-cloud collisions or interactions of massive stars with the surrounding molecular clouds.

The evolution of Giant Molecular Filaments [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 In recent years there has been a growing interest in studying giant molecular filaments (GMFs), which are extremely elongated (> 100pc in length) giant molecular clouds (GMCs).

Improved haplotype resolution of highly duplicated MHC genes in a long-read genome assembly using MiSeq amplicons [PDF]
PeerJ, 2023 Long-read sequencing offers a great improvement in the assembly of complex genomic regions, such as the major histocompatibility complex (MHC) region, which can contain both tandemly duplicated MHC genes (paralogs) and high repeat content.

The metabolic network of the last bacterial common ancestor
Communications Biology, 2021 Joana C. Xavier, Rebecca E. Gerhards and colleagues reconstruct the habitat and lifestyle of the last bacterial common ancestor (LBCA) through the construction of the metabolic network and gene tree analysis of 146 LCBA protein families.

Genomic sequence capture of Plasmodium relictum in experimentally infected birds
Parasites & Vectors, 2022 Background Sequencing parasite genomes in the presence of host DNA is challenging. Sequence capture can overcome this problem by using RNA probes that hybridize with the parasite DNA and then are removed from solution, thus isolating the parasite DNA for

Scientific Reports, 2021 Biologists have reported on the chemical defences and the phenetic similarity of net-winged beetles (Coleoptera: Lycidae) and their co-mimics. Nevertheless, our knowledge has remained fragmental, and the evolution of mimetic patterns has not been studied

Life, 2022 The rooting of phylogenetic trees permits important inferences about ancestral states and the polarity of evolutionary events. Recently, methods that reconcile discordance between gene-trees and species-trees—tree reconciliation methods—are becoming ...

Linking molecular evolution to molecular grafting [PDF]
Journal of Biological Chemistry, 2021 Molecular grafting is a strategy for the engineering of molecular scaffolds into new functional agents, such as next-generation therapeutics. Despite its wide use, studies so far have focused almost exclusively on demonstrating its utility rather than understanding the factors that lead to either poor or successful grafting outcomes.

Loss of Plastid Developmental Genes Coincides With a Reversion to Monoplastidy in Hornworts
Frontiers in Plant Science, 2022 The first plastid evolved from an endosymbiotic cyanobacterium in the common ancestor of the Archaeplastida. The transformative steps from cyanobacterium to organelle included the transfer of control over developmental processes, a necessity for the host
