The earliest stages of planet formation

(PhysOrg.com) -- Small dust particles in a disk of gas around a young star, according to current models, gradually coagulate during the first million years until kilometer-sized objects are formed. These in turn coalesce ...

Particle physicists report 'intriguing hints' of Higgs Boson

Yesterday physicists in Europe reported possible signs of the Higgs boson, a missing piece in the particle-physics puzzle long suspected of giving elementary particles -- such as electrons and quarks -- their mass.
