What happened

'Molecular movie' technology reveals a better way to thwart environmental pollutant Sadie Harley Scientific Editor Robert Egan Associate Editor The latest production from the "molecular movie" imaging technology developed at Oregon State University is a new,…

Why it matters

Based on short-pulse lasers, the imaging technology allows chemical and biological actions to be measured as they are occurring, one high-speed frame at a time.

Common ground

The measurements occur on the level of the femtosecond—one-millionth of one-billionth of a second.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
