Sex Affects Gene Expression in Mammals


Men are from Mars and women are from Venus, so the saying goes. The differences between the sexes have been explored across a variety of disciplines over many years: philosophy, literature and, of course, science. From a biological perspective, however, the effect that sex has on gene expression, particularly in autosomal (sex-linked) genes, has been a relatively unmapped area – until now.


Out of Africa and Into an Archaic Human Mixing Pot


Genetic analysis has revealed that the ancestors of modern humans interbred with at least five different archaic human groups as they moved out of Africa and across Eurasia. Researchers have mapped the location of past “mixing events” (analyzed from existing scientific literature) by contrasting the levels of archaic ancestry in the genomes of present-day populations around the world.


Preventing Eczema Skin Cracks Could Reduce Allergy Issues


Many babies with eczema go on to develop food allergies, asthma and hay fever, and researchers say it’s not a coincidence. The cracks caused by eczema weaken the skin barrier, allowing allergens to penetrate the skin and cause a sequence of allergic diseases.
