Snake sex chromosomes say less about sex and more about survival
Sex-specific chromosomes are a dangerous place to be, if you're a gene. Because these chromosomes—Y chromosomes, in humans—do not have a matching chromosome with which to exchange genetic information, they are prone to losing non-essential genes.....»»

Sex chromosomes responsible for much more than determining sex, study shows
Human sex chromosomes originated from a pair of autosomes, the ordinary or non-sex chromosomes that contain the majority of our genome and come in identical pairs. That ancestral pair of autosomes diverged to become two different chromosomes, X and Y.....»»
How "sleeping" microorganisms can determine the fate of a population
Microorganisms that temporarily "go to sleep" play an important role in the evolution and survival of a population. Mathematician Shubhamoy Nandan conducted research on the effect of this characteristic called "dormancy" in a novel mathematical model.....»»
