A series of quantum physics experiments and theoretical papers now suggest that heat can flow spontaneously from a cold object to a hot one, provided the right quantum conditions are in place. This ...

For two centuries, engineers have trusted a simple rule to predict how heat flows through solids, from jet-engine blades to smartphone chips. Now a set of carefully designed experiments has revealed a ...

Technically, yes, you can bake cookies in a car on an extremely hot day. But you must stick to an egg-free recipe to reduce the risk of food poisoning. That said, your car will smell amazing! This ...

When temperatures soar, so do heart attacks. Now, a lab experiment explains just how temperatures climbing into Fahrenheit’s three-digits can cause ischemia and potential heart attacks, all while ...

If you need to cool something, the gold standard is using a gas compressor arrangement. Of course, there are definite downsides to that, like weight, power consumption, and vibrations. There are solid ...

An interdisciplinary research team including mechanical science and engineering professor Mickey Clemon in The Grainger College of Engineering at the University of Illinois Urbana-Champaign is ...

Heat and color are related—the darker the color, the more heat that is absorbed. On a mostly sunny, 100 degree day, it doesn't take long to melt wax crayons. The video above demonstrates the order of ...

With the world set to blow past 1.5°C of warming, researchers are increasingly studying possible methods of cooling the planet by modifying the atmosphere or the oceans. More geoengineering research ...
