Using a new tool, Cornell University researchers deliberately created atomic-level disorder in order to probe the workings of heavy fermion compounds. They found that, rather than hindering superconductivity, magnetism was an essential ingredient -- and if controlled, may be a key for future advances in the field.

In 2008, the Italian satellite PAMELA detected a curious excess of antimatter positrons 鈥� a startling discovery that could have been a sign of the existence of dark matter. With assistance from the Earth's magnetic field, the Fermi Gamma-ray Telescope confirms a cosmic excess of antimatter positrons, but not the spike expected if evidence of dark matter.

This fall, the Kavli Institute for Cosmological Physics at the University of Chicago and the National Academy of Sciences organized a colloquium that brought together more than 100 cosmologists, particle physicists and observational astrophysicists 鈥� three fields now united in the hunt to determine what is dark matter. Their goal: to take stock of the latest theories and findings about dark matter, assess just how close we are to detecting it and spark cross-disciplinary discussions and collaborations aimed at resolving the dark matter puzzle. So where do things stand?
