An international team of researchers has proposed a way to indirectly measure the rate of cosmic rays striking the Earth over millions of years. In their paper published in the journal Physical Review Letters, they suggest ...
The international Deep Underground Neutrino Experiment, or DUNE, hosted by Fermilab, will be huge. In fact, with more than 1,000 collaborators from over 30 countries and five continents, it's the largest international science ...
