Heat used to transform antiskyrmions to skyrmions and back


Scientists discover a way to transform antiskyrmions to skyrmions and back using heat and magnetic fields.

Mathematical model predicts self-organized learning in real neurons


The free energy principle predicted how real neural connections changed as neurons “learned” in a dish.

Nanopores in deep-sea hydrothermal vents and the origin of life


“Naturally occurring selective nanopore ion channels in deep-sea hydrothermal vents are similar to ion channels found in cells and could help explain the origin of life.
