In altermagnetic materials, atoms form a regular pattern with their spin and spatial orientation alternating on the neighbouring magnetic sites in the crystal. | Photo Credit: Libor Šmejkal (CC BY-SA) Some materials conduct electricity mainly with one kind of charge‑carrier everywhere: either negative electrons (n‑type) or positive ‘holes’ (p‑type).  A rare class can breach this…

When gold is heated really quickly, it seems it remains solid at temperatures far beyond the point where it should have become liquid, a new study in Nature has found. The term for when a solid stays a solid at or beyond its melting point is superheating. Most materials can be superheated only in a…

From bones to immune cells, vitamin D is everywhere, guiding growth and shaping defence. But could it also have an effect on the mind? A major new study suggests so. Published in The Lancet Psychiatry, the study drew from the extraordinary depth of Danish health data to establish whether neonatal vitamin D levels might contribute…

When rocky worlds like the earth began to form, dust in the young Solar System was first heated until it vaporised and then cooled so that the very…
