Gamma cameras see through dense tissue

Gamma rays, valued by astrophysicists for conveying information about phenomena in space, are also becoming valued by doctors for their ability to uncover cancer. As the most energetic form of light, gamma rays are great for revealing astrophysical p... Continue reading

Passing the torch at ATLAS

University of Birmingham physicist Dave Charlton takes over from Fabiola Gianotti as the new spokesperson of the ATLAS experiment. As of March 1, the ATLAS experiment has a new spokesperson: University of Birmingham physicist Dave Charlton, who will ... Continue reading

Fighting for academic freedom, one scholar at a time

Herman Winick thought making synchrotrons was his life’s work, but life had a few surprises in store. A recent symposium honoring Herman Winick’s illustrious career in synchrotron development boasted a stellar guest list. Continue reading

Higgs-like particle

Early in the summer of 2012, excitement reached a peak as members of the CMS and ATLAS collaborations confirmed among themselves that they would soon announce the discovery of what looked like the Higgs boson. In June 2012, particle physicists on exp... Continue reading

Linear collider plans move forward

A new international organization will guide the development of a $7.78 billion particle accelerator that could be heir to the Large Hadron Collider. The two most advanced future particle physics collider projects, the International Linear Collider an... Continue reading

Being unreasonable: the value of pure science

The “unreasonable demands” of pure research are an essential driver for technology, enriching our bodies, minds and pocketbooks. Fermilab’s founding director, Robert R. Wilson, famously responded to the question of how the laboratory wo... Continue reading

Spectroscopy

Spectroscopy is a technique that astronomers use to measure and analyze the hundreds of colors contained in the light emitted by stars, galaxies and other celestial objects. Ordinary telescopes show the directions in which objects are... Continue reading

Cosmic rays born in supernova aftermath

One hundred years after the discovery of cosmic rays, a team of particle astrophysicists has definitively determined one source of these abundant yet enigmatic particles. For decades, researchers have watched cosmic rays, consisting mostly of energet... Continue reading
