Area laws for entanglement in quantum many-body systems give useful information about their low-temperature behaviour and are tightly connected to the possibility of good numerical simulations. An ...

Recent studies have revealed that within cells of both yeast and bacteria, the rates of diffusion of RNA proteins - complex molecules that convey important information throughout the cell - are ...

My previous letter to the editor (“Problems keep piling up in the U.S.,” Dec. 13) was edited for too many words, and what was printed is not the complete story. Here is where it left off and here is ...

I agree wholeheartedly with Jim Greaves (letter to editor, Dec. 5). Our situation is dire and in my opinion, our country is irreparably broken and the mess we all find ourselves in has been a long ...

Inequality in the way nations consume energy has been lessening in recent years. An underlying thermodynamic process seems to be at work. The 18th century writer Adam Smith provided a workable ...

Quantum effects are now commonly used to achieve exceptionally precise measurements, but just how accurate can they get? According to new research from TU Wien and collaborators, published in Nature ...
