Many of the studies that have detected the unusual particle
tracks that we have discussed before are connected with
low energy nuclear reactions (LENR). The connection between
these tracks and LENR is not totally straightforward.
In  I confronted the question: How could we
possibly have been using photographic emulsions in physics for the
last 120 or so years and missed the critical observation that particle
tracks appear when the emulsion is subjected to a uniform exposure
