We demonstrate for the first time that low-energy spin-polarized secondary electrons, produced by irradiation of a magnetic substrate, can induce chiral-selective chemistry. Our approach was to perform detailed measurements of the reaction rate for x-ray induced, secondary electron photolysis of a model chiral compound, (R)- or (S)-2-butanol, adsorbed on a magnetized Permalloy substrate. The results showed that there is an enhancement of approximately 10% in the rate of CO bond cleavage that depends on the chirality of the molecule and the spin polarization of the substrate secondary electrons.

great find Rren
it goes a long way to upset bith the handed and radiation falsehoods presented on page 1
neither destroys the possability of life as stated, 1 helps create the other to promote essentail conditions
its should be one less play to play peek-a-boo with the god of the gaps, but will probabily just get ignored

I personally tend to think that life, along with the rest of the universe, exists in a temporal loop made possible by the permeability of spacetime. That is, time and space are by no means linear, and bits and pieces of it are continuously shifting back and forth, in and out of the past, present and future.
I suspect (since it would be impossible to prove), that every now and then the natural fluctuations of spacetime trap little bits of living material in what would basically be "subspace" bubbles, and throw them off randomly into different places and times. Once in a rare while, these things manage to land on or near a habitable planet, and then evolution is off to the races.
Penrose postulates that each quantum superposition (possible position of the particle) has its own piece of spacetime curvature. According to his theory, these different bits of spacetime curvature are separated from one another, and constitute a form of blister in spacetime. Penrose further proposes a limit to the size of this spacetime blister. This is the tiny Planck scale of (10−35 m). Above this size, Penrose suggests that spacetime can be viewed as continuous, and that gravity starts to exert its force on the spacetime blister. This is suggested to become unstable above the Planck scale, and to collapse so as to choose just one of the possible locations for the particle. Penrose calls this event objective reduction (OR), reduction being another word for wave function collapse.
Anyway, what this little notion does is remove from the equation the requirement for there to be a conscious, intelligent entity of some sort guiding the genesis. It creates a problem for the Creationists, who hope to use the concept of "God" as a default explanation for the existence of life.
Unlike the random, "subjective reduction"(SR, or R) of standard quantum theory caused by observation or environmental entanglement, the OR we propose in microtubules is a self-collapse and it results in particular patterns of microtubule-tubulin conformational states that regulate neuronal activities including synaptic functions. Possibilities and probabilities for post-reduction tubulin states are influenced by factors including attachments of microtubule-associated proteins (MAPs) acting as "nodes"which tune and "orchestrate"the quantum oscillations. We thus term the self-tuning OR process in microtubules "orchestrated objective reduction"("B>Orch OR", and calculate an estimate for the number of tubulins (and neurons) whose coherence for relevant time periods (e.g. 500 milliseconds) will elicit Orch OR. In providing a connection among 1) pre-conscious to conscious transition, 2) fundamental space-time notions, 3) non-computability, and 4) binding of various (time scale and spatial) reductions into an instantaneous event ("conscious now", we believe Orch OR in brain microtubules is the most specific and plausible model for consciousness yet proposed.
The place of consciousness in evolution is unknown, but the actual course of evolution itself may offer a clue. Fossil records indicate that animal species as we know them today including conscious humans all arose from a burst of evolutionary activity some 540 million years ago (the "Cambrian explosion"). It is suggested here that:
1. Occurrence of consciousness was likely to have accelerated the course of evolution.
2. Small worms, urchins and comparable creatures reached critical biological complexity for emergence of primitive consciousness at the early Cambrian period 540 million years ago.
3. Cooperative dynamics of microtubules, cilia, centrioles and axonemes were the critical biological factors for consciousness.
4. Cytoskeletal complexity available in early Cambrian animals closely matches criteria for the Penrose-Hameroff Orch OR model of consciousness.
5. Orch OR caused the Cambrian explosion.
If you eliminate from the argument some basic assumptions about space and time, there are other ways it could have happened.
