In most species mitochondrial DNA (mtDNA) is inherited maternally in an apparently clonal fashion, although how this is achieved remains uncertain.Population genetic studies show not only that individuals can harbor more than one type of mtDNA (heteroplasmy) but that heteroplasmy is common and widespread across a diversity of taxa.Females harboring
Atmospheric aerosol composition is often analyzed using thermal desorption techniques to evaporate samples and deliver organic or inorganic molecules to various designs of detectors for identification and quantification.The organic aerosol (OA) fraction is composed of thousands of individual compounds, some with nitrogen- and sulfur-containing func
This paper provides an invitation to analytic abduction, an emerging approach to qualitative research.Like deduction and induction, abduction is a mode of inquiry.In a general sense, abduction forwards explanations for novel or surprising observations.In a more practical sense, abduction aims to combine the strengths of both inductive and deductive
PIWI-interacting RNAs (piRNAs) direct Piwi to repress transposons and maintain genome integrity in Drosophila ovarian somatic cells.piRNA maturation and association with Piwi occur at perinuclear Yb bodies, the centers of piRNA biogenesis.Here, we show that piRNA intermediates arising from the piRNA cluster flamenco (flam) localize to perinuclear f
