Summary: The new direction of this research is to try to find out whether the lightest sub-atomic particles, called neutrinos, can be responsible for the matter anti-matter asymmetry of the universe which we observe. These particles are very difficult to measure and it has taken many decades since their initial discovery to get to the position where we might be able to see a difference between the behaviour of
neutrinos and their anti-particles. For this we need extremely massive detectors, because neutrinos only interact with matter via the Weak force (the weakest of the fundamental forces) and this limits the precision of the experiments owing to cost. Our new direction is to try to develop a low cost detector using naturally occurring lakes as the water "target" and to measure the Cherenkov light that the neutrinos decay products produce in the water. This could allow us to build detectors of 1Mt in the future which would allow us to make very precise measurements of the neutrino oscillations, an effect discovered in the last 15 years which proves that neutrinos have a very small, but non-zero, mass.
