I recently read ' Life on the Edge" by Jim Al-Khalili and Johnjoe McFadden. It was very readable and it got me quite convinced about the whole idea. Al-Khalili is a very presentable broadcaster / writer and offers an attractive case. But it was written some while ago and Google hasn't much to offer about subsequent work. The topic has appeared on PF several times but always seems to die an early death, with pretty short threads and lack of momentum. Has anyone read more recent stuff (something as approachable as that book, preferably)? The connection between Biology and QT has a good pedigree (going back to Schrodinger etc.) so it can't be just written off. Have the past threads died just because of lack of interest or do they stray too far into the realms of Nutty Science? The statistics of biological processes are fairly critical and QM seems to account for tipping the balance in favour of survival. I would love to read some well informed opinions about this.
