Two nearby black holes are the most massive yet found, with masses—of around ten billion solar masses—considerably greater than predicted by conventional methods relating black-hole mass with the stellar velocity dispersion and bulge luminosity of the host galaxy.

Negative refraction—light bending opposite to conventional refraction—and a hyperlens effect is observed in an excitonic system in the two-dimensional magnet CrSBr. The effect is mediated by the magnetic order of the material.

The small spin-orbit interaction makes transduction between the magnetic and optical information challenging in organic materials. Here, the authors show that the room temperature electroluminescence of an organic material can be controlled by the fringe fields of a nearby magnet.

Why Earth’s crust only started becoming widely preserved in the Eoarchaean, 500 Ma after planetary accretion, is poorly understood. Here, the authors document a shift to juvenile magmatic sources in the early Eoarchaean, linking crustal preservation to the formation of stabilising melt-depleted mantle.
