Scientists investigate the specific local geological and climatic factors behind the 2014 collapse of a hillside in Oso, Washington. Learn what triggered the deadliest U.S. landslide in decades.

On July 4, 2012, scientists at the giant atom-smashing facility at CERN announced the discovery of a subatomic particle that seems like a tantalizingly close match to the elusive Higgs Boson, thought to be responsible for giving all the stuff in the universe its mass. Since it was first proposed nearly fifty years ago, the Higgs has been the holy grail of particle physicists: in finding it they validate the "standard model" that underlies all of modern physics and open the door to new discoveries when CERN's Large Hadron Collider switches on at higher power in 2015.
