Researchers from the University of Buffalo found a counter-intuitive way of improving the water-purification process: keeping things cool.

By using carbon-dipped paper to weaken light intensity, their new system increases efficiency and provides a more affordable water-treatment system. The university team hopes the technology will soon support disaster-relief in countries impacted by natural disasters.
