Most body parts grow proportionally with the rest of the body as individuals of a species become larger, although scientists have long known that visual cues of reproductive prowess are a special case. But is this the case with everyone?
Female X chromosome 'cracked' - "The discovery, by an international consortium of scientists, shows that females are far more variable than previously thought and, when it comes to genes, more complex than men." Nature reports two new studies; one on the complete sequencing of the X chromosome for humans, which sheds some light on how sex evolved and how women differ from men, and another on how women express many genes from X chromosomes previously thought dormant.
Yikes! The strange case of the homosexual necrophiliac duck pushed out the boundaries of knowledge in a rather improbable way when it was recorded by Dutch researcher Kees Moeliker.
