SYDNEY, 25 August 2006: British scientists have found that enzymes
cheat time and space by quantum tunnelling – a much faster way of
travelling than the classical way – but whether or not perplexing
quantum theories can be applied to the biological world is still hotly
Until now, no one knew just how the enzymes speed up the reactions,
which in some cases are up to a staggering million times faster.
