<p>Scientists love coffee. More than anyone else, by some surveys. So in a way, it makes perfect sense that they would be responsible for what could be the greatest coffee-related invention since coffee-alcohol: a mug that keeps coffee hot but not too hot for hours on end.</p>
<p>Cf Joulies that work on the same principle. Would be easier to use if the drink container took care of it.</p>
