Earth's neutrino absorption rate measured for the first time
In a first, scientists at the IceCube collaboration have measured the rate at which Earth absorbs high-energy neutral subatomic particles called neutrinos. IceCube, the world's largest neutrino detector, has 5,160 optical sensors encased within a cubic kilometre of Antarctic ice near the South Pole. The detection, made by observing neutrinos' interaction with ice, would help study Earth's core.
