Like astronomers counting stars in the familiar universe of outer space, chemists in Switzerland are reporting the latest results of a survey of chemical space — the so-called chemical universe where tomorrow's miracle drugs may reside.

Word of the Day
  • A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
The word 'pawl' probably comes from a Latin word meaning 'stake'.
