I'm in college for nursing, actually, so human biology interests me.<br/><br/>I wasn't able to find the original document, so I'll just lay it out from memory.  Basically, some species evolved a specialized (battery) cell that exists in the subdermis, similar to the cells that produce vitamin D.  When radiation (i.e. sunlight) strikes it, the cell absorbs some of it via chemical reaction, then uses rapidly switching ions to store the charge in the cell.  If you can remember high school biology, neurons use ions to progress electrical charges along the axon.  It's the same principle, except the charge runs on a continuous circuit throughout the cell.  Thus, battery cell.<br/><br/>Although it mostly comes from sunlight, the cells can also absorb ultraviolet and background radiation from the environment.<br/><br/>To use the energy, the cells link up to specialized neurons and transfer the charge.  The neurons deliver the energy to the fingertips, where it is expelled.  A minute organ in the brain that stores trace metals is able to control the energy once it leaves the body through a weak magnetic field.  The system is highly complex and has evolutionary biologists baffled, unable to figure out how such a specialized organ developed.  (Maybe this is where the mother race comes in?)<br/><br/>The energy can be directed freely (telekinesis), condensed in order to ionize atoms and create electrical charges, focused to ignite matter (fire), or simply dispersed.  I'm sure pioneering individuals will find new ways to use it.<br/><br/>As for mind reading...   Hmm....<br/><br/>Dense clusters of modified battery cells form biological electrodes in the upper ceiling of the skull.  These can pick up resonant disruptions produced by electrical charges.  When the electrical "ripple" reaches the battery cells, it stimulates an action potential ("action potential" is a fancy name for the electrical charges produced by cells).  The frequency and number of these action potentials are interpreted as noise by the brain.  It is up to the individual to decipher the signals.  The bio-electrodes pick up ALL electrical signals, of course.  Everything from ceiling lights to lightning bolts to static.  The raw amount of extra-sensory feedback would drive a person insane, so they have learned how to block the "noise".  This means someone with these bio electrodes can flip their electrical feedback on and off at their leisure.<br/><br/><br/><br/>How's all that?
