    Research: Titles and abstracts of scientific reports ignore variation among species

    Barbara R Migeon
    Ignoring the probability of species variation when reporting observations about biological processes leads to misinterpretation of the experimental data.

    Natural variation in autumn expression is the major adaptive determinant distinguishing Arabidopsis FLC haplotypes

    Jo Hepworth et al.
    Variation in autumnal expression from starting expression levels and initial cold-down-regulation, rather than epigenetic silencing, is the major field variable conferred by worldwide haplotypes of the floral repressor gene, FLC.

    Extensive intraspecies cryptic variation in an ancient embryonic gene regulatory network

    Yamila N Torres Cleuren et al.
    Quantitative genetic analyses reveal remarkably broad genetic variation underlies the requirement for two critical regulatory inputs into a core embryonic gene regulatory network within one animal species.

    Variation in olfactory neuron repertoires is genetically controlled and environmentally modulated

    Ximena Ibarra-Soria et al.
    The neuronal composition of a mouse’s nose is individually unique due to a combination of olfactory experience and genetic variation local to olfactory receptor genes.

    The genomic landscape of human cellular circadian variation points to a novel role for the signalosome

    Ludmila Gaspar et al.
    Cellular genetics highlights differences in protein catabolism in general, and the COP9 signalosome in particular, as one major source of human cellular circadian variation.

    Natural genetic variation in Arabidopsis thaliana defense metabolism genes modulates field fitness

    Rachel Kerwin et al.
    Environmental heterogeneity may contribute to the high levels of genetic variation in glucosinolate genes found in Arabidopsis thaliana.

    Evolution of extreme resistance to ionizing radiation via genetic adaptation of DNA repair

    Rose T Byrne et al.
    Experiments on E. coli show that multiple mechanisms contribute to extreme resistance to ionizing radiation in bacteria, with mutations to three genes for DNA repair having a prominent role in one evolved population.

    Passive and active DNA methylation and the interplay with genetic variation in gene regulation

    Maria Gutierrez-Arcelus et al.
    Detailed analysis of umbilical cord cells shows that the associations between DNA methylation, gene expression and genetic variation are complex and context-dependent.

    Dietary sugar inhibits satiation by decreasing the central processing of sweet taste

    Christina E May et al.
    Taste-dependent satiation, which induces proper cessation of feeding in mammals as well as insects, is weakened by sugar-diet-driven taste impairment in the fruit fly.
