A new theory of quantum subsystems

When studying a complex system, scientists identify smaller pieces called subsystems that they can make sense of. By studying subsystems and the correlations between them, they reconstruct an understanding of the whole.

Shining a light on dark matter one particle at a time

University of Adelaide experts are trying to unlock the secrets of dark matter, which makes up 84% of the matter in the universe, but we know little about it. Researchers are using a new tool that could signal the existence ...

Mercury removal made easy in toxic environments

Mercury pollution is a global problem in water, air and soil near goldmines, cement and some metal production, and other heavy industries burning fossil fuels—with removal too expensive or difficult in some of the poorest ...

Advancing materials science for superconducting quantum circuits

NPL scientists, in collaboration with experts in physical chemistry, have unleashed state-of-the-art electron paramagnetic resonance (EPR) techniques to understand materials relevant for superconducting quantum circuits, ...

Time travel could be possible, but only with parallel timelines

Have you ever made a mistake that you wish you could undo? Correcting past mistakes is one of the reasons we find the concept of time travel so fascinating. As often portrayed in science fiction, with a time machine, nothing ...

Antarctic sea-ice expansion in a warming climate

Antarctic sea-ice has expanded over the period of continuous satellite monitoring, which seemingly contradicts ongoing global warming resulting from increasing concentrations of greenhouse gasses. In a study, published in ...

Flexible quantum sieve filters the fuel of starship Enterprise

Deuterium, the heavy brother of hydrogen, is considered a promising material of the future because of its wide range of applications—in science, for energy generation, or in the production of pharmaceuticals. However, the ...
