The result hints at the existence of a new and very strong fundamental interaction — the process that holds [quarks] together inside the protons.… A number of theorists have speculated about its nature and […]

Earth’s journey through the Milky Way might have helped create the planet’s first continents. Comets may have bombarded Earth every time the early solar system traveled through our galaxy’s spiral arms, a new study suggests. Those recurring barrages in turn helped trigger the formation of our planet’s continental crust, researchers propose August 23 in Geology. […]
