Biochemists working at the University of California, San Diego, have developed a program that predicts the placement of chemical marks that control the activity of genes based on sequences of DNA. They describe their analysis and report results from its application to human embryonic cells in a paper published in Nature Methods online September 21.

It's the faintest light, yet it carries information from the beginning of time. A telescope trained on the Antarctic sky has picked up swirling patterns of light believed to be the imprint of the violent expansion of the universe a trillionth of a trillionth of a trillionth of a second after it burst into being.
