Scientists on the Dark Energy Survey have released the first in a series of dark matter maps of the cosmos. These maps, created with one of the world's most powerful digital cameras, are the largest contiguous maps created ...
The world's largest particle smasher restarted Sunday after a two-year upgrade that will allow physicists to explore uncharted corners of what makes up the universe, including dark matter and antimatter.
When Kevin McDermott and Susan Dittmer talk about what they might discover when their particle detector goes back online in Switzerland, it's a little like talking to a 5-year-old on Christmas Eve.
In 1980, Walter Alvarez and his group at the University of California, Berkeley, discovered a thin layer of clay in the geologic record, which contained an unexpected amount of the rare element iridium.
