Quantum Tunnelling

Scientists at the University of Leicester have shown that the textbook explanation of how enzymes work is wrong - at least for some enzymes.

I wouldn't go as far as saying that they are redefining how enzymes work... all molecules experience tunneling of some sort.  Hydrogen very often tunnels through rotational barriers and even through the nucleus as with ammonia; however, all this is described in the wavefunction of the molecule...  what I guess the article is trying to say is that, their approximation methods are underestimating the importance of tunneling in their models.  As with the case with anything larger than helium, wavefunctions need to be approximated using a variety of methods
I've got nothin'

What about richochet in a laser. Has that got to do with 'little thingsof everythings' ? Anyway, don't quite understand what richochet has to do with it.
