BIG HOPES FOR TINY, NEW HYDROGEN STORAGE MATERIAL, March 22
Researchers at the Department of Energy's Pacific Northwest National Laboratory are taking a new approach to "filling up" a fuel cell car with a nanoscale solid, hydrogen storage material. Their discovery could hasten a day when our vehicles will run on hydrogen-powered, environmentally friendly fuel cells instead of gasoline engines.
The challenge, of course, is how to store and carry hydrogen. Whatever the method, it needs to be no heavier and take up no more space than a traditional gas tank but provide enough hydrogen to power the vehicle for 300 miles before refueling.

LIGHT MAY ARISE FROM RELATIVITY VIOLATIONS, March 22
Light as we know it may be a direct result of small violations of relativity, according to new research scheduled for publication online Tuesday (March 22) in the journal Physical Review D.
In discussing the work, physics professor Alan Kostelecky of Indiana University described light as "a shimmering of ever-present vectors in empty space" and compared it to waves propagating across a field of grain. This description is markedly different from existing theories of light, in which scientists believe space is without direction and the properties of light are a result of an underlying symmetry of nature.

LEADING EXPERTS WEIGH-IN ON THE INTERPRETATION OF QUANTUM THEORY: LECTURES AVAILABLE ON-LINE, March 22
Perimeter Institute for Theoretical Physics, in conjunction with the University of Waterloo, is offering a technical but pedagogical lecture series on the problems associated with developing a consistent understanding of the nature of objective reality in light of quantum theory.
The series is called "The Interpretations of Quantum Theory: Current Status and Future Directions" and includes invited lectures from leading theoretical and experimental physicists, including Anton Zeilinger (University of Vienna), Alain Aspect (Universitй de Paris, Orsay), Robert Griffiths (Carnegie Mellon), and several prominent Perimeter Institute scientists including Long Term Researcher Lucien Hardy.
