Everybody is aware about what peer-reviewing is: two persons having, more or less professionally, validated a scientific document. No more, no less.
And yes, posts on social networks often do more buzz that peer-reviewed papers, so what?

I've read this carefully, and, I disagree a lot. A million things have changed in the way science works since the 1950's; to blame peer-reviewing appears arbitrary. Bibliometry-based evaluation, journal esteem hierarchy, merchandizing of scientific knowledge, oligopoly of big publishers are much more plausible causes of our systemic problems.

Nice, thanks!
What is the existing evidence for (1) the genome shock hypothesis and (2) the aridity hypothesis?

Using a theoretical model, we show that the strength of gBGC should be under weak stabilising selection around an evolutionary optimum. We then provide in depth characterization of the evolutionary parameters that influence the optimal value of gBGC and the strength of selection around it. Surprisingly, we reveal that despite a deleterious effect for the population, gBGC is still beneficial to individuals, which might explain its high prevalence in eukaryotes. (2/2)

Hi everybody,

I am pleased to share with you my latest work in collaboration with Augustin Cléssin and Nicolas Lartillot:

GC-biased gene conversion (gBGC) is a process that distorts the segregation of heterozygous AT:GC polymorphisms during meiotic #recombination. This genome-wide non-Mendelian segregation has been shown to be a major source of #genetic load, earning the nickname of “Achille’s heel” of #genomes. (1/2)

Does Effective Population Size Govern Evolutionary Differences in Telomere Length?

Abstract. Lengths of telomeres vary by an order of magnitude across mammalian species. Similarly, age- and sex-standardized telomere lengths differ by up t
