So, for instance, some studies look into the extent to which quantum effects are behind the navigation of birds, turtles and insects using the Earth’s weak magnetic field. If so, insights about how those effects work could potentially be translated into electromagnetic sensors with unprecedented sensitivity and high resilience to noise — because nature-made sensors work well in various environments. The other thrust delves into whether the physiology of humans and other organisms can be influenced by manipulating quantum effects. An example comes from early evidence that certain elements of cellular metabolism are affected by electromagnetic waves in a way that is consistent with a quantum model. Revealing the underlying mechanisms may have implications for new ways of treating and diagnosing disease. “
The CISS chiral induced spin selectivity effect underpins the fact that charge transport through nanoscopic chiral structures favors a particular electronic spin orientation, resulting in 3 large room-temperature spin polarizations. Observations of the CISS effect suggest opportunities for spin control and for the design and fabrication of room-temperature quantum devices from the bottom up, with atomic-scale precision.
A Chirality-Based Quantum Leap
"This difference in commutation properties can be traced back to the Coulomb interaction, where the non-commutativity is a manifestation of the exchange inter action introduced by the local Coulomb repulsion. The con-sequences of this property is discussed in more detail below. "

"The key here is the non-commutativity of the SU(2) spin algebra, which breaks the time-reversal
symmetry, and leads, in the presence of electron coherence, to a permanent electron current."
