Discovery of a new Hall effect: Does it violate Onsager"s reciprocal theorem?
Researchers at the University of Tsukuba and NIMS have observed a novel Hall effect wherein the deflection direction of current varies according to the current flow direction. Onsager's reciprocal theorem, a fundamental theorem in materials science,.....»»
Permselectivity reveals a cool side of nanopores
Researchers from Osaka University investigated the thermal energy changes across nanopores that allow the selective flow of ions. Switching off the flow of ions in one direction led to a cooling effect. The findings have applications in nanofluidic d.....»»
Study suggests climate played a crucial role in human migration from Africa
About 6 million years ago, in the deep forests of eastern Africa, something spectacular happened. Chimpanzees, our closest relative in the animal kingdom, evolved in one direction, while our earliest ancestors continued in another......»»
Why the success of COP28 depends on climate finance

Study of wintering sites shows bat seasonal migration is more complex than previously assumed
In late summer, some bat species migrate from northern Europe along the coastlines to their wintering sites in central and western Europe. Until now it was assumed that all bats traveled in the same direction during the migration. However, the realit.....»»
Boomerang-like beams of light: Research makes progress toward observing quantum backflow in two dimensions
Researchers at the University of Warsaw's Faculty of Physics have superposed two light beams twisted in the clockwise direction to create anti-clockwise twists in the dark regions of the resultant superposition. The results of the research have been.....»»
