When you look up at the night sky, what do you see? Tiny points of light dotting what we tend to think of as empty space. But a growing body of evidence suggests the emptiness actually contains a type of matter we can't see - the ever-elusive dark matter.

Are we any closer to detecting this strange substance? While we are far from truly understanding it, the Cryogenic Dark Matter Search project at Fermilab has given the theory a recent boost. Science in Seconds reports.

(Editor's note: The CDMS team contains exactly ONE Canadian researcher, Dr. Wolfgang Rao, who likened the experiment to "finding a needle in a haystack [by] getting rid of some of the hay." Happy Canada Day! )
