BBCnews is carrying this summary of a recent development in physics. Scientists have developed a timing technique that allows them to record events in 100 "attosecond" intervals. What's an attosecond?

[If] 100 attoseconds is stretched so that it lasts one second, one second would last 300 million years on the same scale.

The development is expected to allow new sorts of quantum experiements to become possible. They're already taking pictures of electrons leaving an atom.
