Physicists report that temperature gradients within pores in rock could have separated primitive biopolymers on the basis of their sequences -- a vital precondition for the formation of ...

The flow of top- and bottom-level currents in the Atlantic Ocean appear to be slowing down and may be due for a reversal like one that happened 10,000 years ago, according to new data. By studying ...
