One copy of the human genome is more than 3 billion nucleotides in length, and weighs in at about 3.5 picograms (pg, or trillionths of a gram). Only about 1.5% of this is composed of our 20,000 or…

Once considered a barren plain dotted with hydrothermal vents, the seafloor's rocky regions appear to be teeming with microbial life, say scientists from the Woods Hole Oceanographic Institution (…
