British physicist Peter Higgs, who first theorized the existence of the boson 40 years ago, attends a scientific seminar near Geneva following the discovery of the subatomic particle on July 4, 2012.
Researchers working with a $5.5 billion atom smasher at the CERN particle physics lab in Geneva observed the elusive Higgs boson particle, which holds the key to explaining how other elementary particles get their mass. (Maximilien Brice and Claudia Marce
A new technique that binds special molecules to single strands of DNA allowed researchers to sequence the complete Neanderthal-related Denisovan genome from a tiny fragment of ancient finger bone. (Max Planck Institute for Evolutionary Anthropology)
