    ‘Smart’ windows could save energy

    Tiny chemical droplets in a liquid sandwiched between panes of glass turn cloudy when they warm up. This will block some sunlight and potentially save on air conditioning bills.

    Don’t hold ’em – just fold ’em

    Scientists have designed a problem-solving process that allows a computer to win at a kind of poker. It gives a computer enough knowledge to win against any opponent — eventually.

    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.
