To understand how heat normally flows, you could study the second law of thermodynamics – or wrap your hands around a hot mug of coffee. Both tell us that heat tends to flow toward cooler regions. As ...

A forgotten cup of coffee will gradually cool down as its heat flows into the cooler surrounding air, but in the quantum realm, it appears this experience can be turned on its head. As a result, we ...

Differential scanning calorimetry (DSC) is a thermal analysis method that measures the difference between the rate of heat flow into a specimen and into a reference, measured as a function of ...

Biophysicists have demonstrated how heat flows through rock fissures could have created the conditions for the emergence of life. Life is complicated. What is true for our everyday existence also ...
