Epigenetics has become a hot topic in biology. There are players "above DNA"– some heritable – that may be more important than the genetic code itself.
Within the factories of molecular machines that run living cells, including those in the human body, processes occur non-stop that are designed to meet every contingency. Here are just a few examples.
Another epic photo of Earth from space was taken on July 19 of Earth from Saturn by Cassini, and released on July 22. From Mercury, the MESSENGER spacecraft also portrayed Earth as a small dot.
