When trying to understand the origins of life on Earth, researchers run into a paradox: while water is an indispensable solvent for all known life forms that exist today, water also inhibits the formation of string-like chains ...
By comparing the human genome to the genomes of 34 other mammals, Australian scientists have described an unexpectedly high proportion of functional elements conserved through evolution.
