A series of quantum physics experiments and theoretical papers now suggest that heat can flow spontaneously from a cold ...

We are used to heat flowing from hot objects to cool ones, and never the other way round, but now researchers have found it is possible to pull off this trick in the strange realm of quantum mechanics ...

In order to build the computers and devices of tomorrow, we have to understand how they use energy today. That's harder than it sounds. Memory storage, information processing, and energy use in these ...

Physicists have demonstrated that waves can bounce off boundaries in time, not just in space, producing signals that behave ...

Interpretability is the science of how neural networks work internally, and how modifying their inner mechanisms can shape their behavior--e.g., adjusting a reasoning model's internal concepts to ...

If anyone ever asked how many brothers we were, it was always four. David, Peter, Timothy and me. Timothy was gone, but we’d ...

A relatively simple experiment involving asking a generative AI to compare two objects of very different sizes allows us to ...

To achieve a deep understanding of the CMAS corrosion mechanism and lifetime prediction of high-performance thermal/environmental barrier coating materials, the (Er1/4Y1/4Lu1/4Yb1/4)2Si2O7 and ...
