Oftentimes called “ghost particles,” neutrinos can travel through nearly everything (the sun, the earth, you!) undetected. Because they are nearly massless, gravitational fields do not affect neutrinos; Similarly, because they are chargeless, electric and magnetic fields do not con affect neutrinos. This lack of interaction is advantageous for IceCube researchers – when they detect a neutrino, it is a
Students will use marshmallows to simulate toxins in the environment. Concentrations of these toxins will be modeled and calculated as they bioaccumulate up the food chain. Methylmercury and POPs are substances that bioaccumulate in the Arctic food chain. OASIS scientists studied these in Barrow, Alaska.
