1999 NOBEL PRIZE FOR PHYSICS The Royal Swedish Academy of Sciences awarded the 1999 Nobel Prize for Physics to two Dutch physicists who created the mathematical foundations of the Standard Model of particle physics.

EXTRA DIMENSIONS? Extra spacetime dimensions might permit the physical forces to become unified at much lower energies. Why don't we see these dimensions?

PROGRESS ON UNDERSTANDING NEUTRINO OSCILLATIONS. In Japan, an accelerator and an underground detector 250 km away are teaming up to look for an exotic property of neutrinos.

THE ARROW OF TIME has been measured at CERN and Fermilab by measuring CP violation (CP is related to the slight asymmetry between matter and anti-matter).

FIRST EVENTS AT THE B FACTORY. "This is the first big step in our attempt to measure CP violation with B mesons and thereby understand why the universe contains so much more matter than antimatter"

INTRIGUING INDICATIONS OF CP VIOLATION IN B MESONS has turned up at Fermilab. CP is a symmetry that turns a particle into an antiparticle (charge conjugation, or C) and then sends the particle through a looking glass (parity reflection, or P).

A REPULSIVE FORCE IN THE UNIVERSE seems to be at work on a cosmic scale, at least partly neutralizing the attractive force of gravity.
