Flood Forensics: Why Colorado's Floods Were So Destructive

Nearly a year's worth of rain was dumped on parts of the state in four days this fall. The downpour from the heavens created a slurry on the mountainsides that scrubbed away soil, trees, boulders and buildings. Scientists say the flooding may have been a once-in-a-thousand-years event.

Shutdown Forces Antarctic Research Into 'Caretaker Status'

Scientists who do research in Antarctica have just learned that the shutdown will effectively cancel all of their planned fieldwork on the icy continent this year. All research activities not essential to human safety and the preservation of property will be stopped.

Researches Who Theorized 'God Particle' Get Physics Nobel

This year's Nobel Prize in Physics was awarded jointly to François Englert of Belgium, and British scientist Peter W. Higgs. The two scientists independently, and at almost exactly the same time, proposed the existence of the so-called "God particle" or Higgs boson as part of a mechanism that explains how the universe works at the most fundamental level. Their theory was recently confirmed by experiments this summer at CERN's Large Hadron Collider in Geneva.
