Postcards from the terascale

In February, the Department of Energy's Office of Science and the National Science Foundation asked the High Energy Physics Advisory Panel "to form a committee to write a document" that addresses the synergies and complementarities of the Large Hadron Collider, now under constructi

Distant quasar

On the night of April 27, 2002, the Apache Point 3.5 m telescope in New Mexico captured the light signature of SDSS 1148+5251, the most distant quasar known. A quasar is a compact, ultraluminous object thought to be powered by material falling into a giant black hole.

A curious paradox

A curious paradox faces modern science. Scientists are specializing more than ever before within their fields of research but some of the greatest progress is being made by those who bridge fields using a cross-fertilization of ideas.
