The science world might have tapped into something that is literally slower than molasses. Researchers at Ireland's Trinity College set up a camera to capture a pitch drop that was 69 years in the ...

Researchers at Trinity College Dublin have managed after seven decades to capture on film the world's most anticipated drip. Researchers at Trinity College Dublin have some long awaited test results: ...

Most experiments are designed to be done quickly. Get data, analyze data, publish data, move on. But the universe doesn’t work on nice brief timescales. For some things you need time. Lots of time.

It was “brute curiosity,” says Edward L. Cussler Jr., that led him to fill a University of Minnesota-Twin Cities swimming pool with guar gum two years ago. The chemical-engineering professor was ...
