Mark your calendar for the world's most comprehensive hematology event of the year, the 61st ASH Annual Meeting and Exposition in sunny Orlando.
The meeting will provide an invaluable educational experience and the opportunity to review thousands of scientific abstracts highlighting updates in the hottest topics in hematology.
This study provides a comprehensive picture of affinities among Khoe-San groups, prior to the arrival of recent migrants, and found that these affinities are primarily determined by the geographic landscape.
Chemical signaling in animals often plays a central role in eliciting a variety of responses during reproductive interactions between males and females.
Here, we combined whole transcriptome sequencing, proteomics, histology, and molecular phylogenetics in a comparative approach to investigate SPF occurrence in male breeding glands across the evolutionary tree of anurans (frogs and toads).
Our study shows that multiple families of both terrestrially and aquatically reproducing frogs have substantially increased expression levels of SPFs in male breeding glands.
Even though isolation-by-distance explained most genetic affinities between the different autochthonous groups, additional signals of contact between Khoe-San groups could be detected.

Meiotic recombination generates genetic diversity upon which selection can act.
Recombination rates are highly variable between species, populations, individuals, sexes, chromosomes, and chromosomal regions.
Please do make a note of the key dates included below. Southern African indigenous groups, traditionally hunter-gatherers (San) and herders (Khoekhoe), are commonly referred to as “Khoe-San” populations and have a long history in southern Africa.
