The hotter it gets, the more it glows. This rule applies to stovetops and light bulbs alike. But it doesn't hold true for all everything. Scientists report finding a rule-breaker — one that appears to cool down even as its temperature climbs.
A material like this could be used to build objects that can fool infrared cameras, the kind that see heat, rather than visible light. It may also help scientists design heating and cooling systems that will use less energy. The new study was published O...
