The author's conclusion is this :
There is accumulating and tantalizing evidence that quantum mechanics plays a key role here and there in biology. What is lacking is any clear case for a general quantum life principle that might offer a new conceptual framework in which the remarkable properties of living systems can be understood, as Schrödinger and others hoped. However, the physics of complex far-from-equilibrium quantum systems with non-linear couplings is in its infancy, and further surprises undoubtedly lie in store. Meanwhile, researchers in quantum-information science intent on reducing decoherence might find the study of biological nanomachines surprisingly rewarding.
Recent efforts to plug into DNA for the purpose of processing data or using it as a switching mechanism are leading the way.

“Today, we know that no special life force is at work in biology; there is just ordinary matter doing extraordinary things, all the while obeying the familiar laws of physics.”
Just like there are vast amounts of radio waves on Earth that don’t do anything. Carry data? Why, that would suggest that radio waves are intelligent. What nonsense! They just obey the familiar laws of physics.
His error is assuming that life and it life force are two different things. The human body clearly has energy, of several different kinds. How impossible would it be to think that this energy also carried data?

If I could only find someone who can explain quantum mechanics.

(Yes, we disagree - no, we won't shut up - no, we won't quit.)
Quantum mechanics can not explain information-rich DNA, and more importantly, the meaning of codons and their associated amino acids.

A distinctive feature of biology is the exquisite choreography involved in its highly complex molecular self-organization and self-assembly. For the cell to perform properly, it is crucial that the right parts are in the right place at the right time. Quantum mechanics sets fundamental limits to the accuracy with which molecules can co-operate in a collective and organized way. We might expect some of lifes processes to evolve at least as far as the quantum edge, where a compromise is struck between speed and accuracy. The 19th-century view of life as magic matter, exemplified by the use of the term organic chemistry, has been replaced by a model of the cell as a complex system of linked nanomachines operating under the control of digital software encoded in DNA. These Lilliputian components, made mostly from proteins, include pumps, rotors, ratchets, cables, levers, sensors and other mechanisms familiar to the physicist and engineer.
