This year's Nobel Prize in Physics has been awarded a Japanese and a Canadian scientist for their work on tiny puzzling subatomic particles known as neutrinos. Neutrinos are the second most bountiful particles after photons, the particles of light, with trillions of them streaming through our bodies every second, but their true nature has been poorly understood. Takaaki Kajita did early work on the tiny particles at a purpose-built underground laboratory a kilometer beneath a mountain in central Japan. Canadian Arthur McDonald was also awarded the prize. His work at the Sudbury Neutrino Observatory demonstrated that neutrinos from the Sun don't disappear on their way to Earth, but change form instead.
