Detecting a single proton
Doctors typically use magnetic-resonance imaging, or MRI, to see tissues and organs inside the body. Physicists can harness a similar technology. And they did that to spotlight something even smaller — a single proton. But followup analyses, reported in January 2015, forced a retraction of their original claim.

How science saved the Eiffel Tower
The Eiffel Tower was an engineering masterpiece. But Parisians initially thought it too ugly to let stand for more than 20 years. So Eiffel made the tower a bastion of science. And that would soon ensure that the structure was too valuable to tear down.

Nobel goes for creating the ‘nanoscope’
A regular microscope can’t bring into focus the nanoscale molecules from which cells are built. Using lasers and fluorescent molecules, three scientists found a way to view these tiny features. Their reward: the 2014 Nobel Prize in chemistry.
