Icy moons circling the outer planets may be far more dynamic—and explosive—than they appear. New research suggests that when heat from tidal forces melts their ice shells from below, the sudden drop in pressure could cause hidden oceans to boil beneath the surface. On smaller moons like Enceladus, Mimas, and Miranda, this process may help explain strange features such as Enceladus’ tiger stripes and Miranda’s towering cliffs.

Twisting atomically thin magnetic layers does more than reshape their electronics—it can create giant, topological magnetic textures. In chromium triiodide, researchers observed skyrmion-like patterns stretching far beyond the expected moiré scale, reaching hundreds of nanometers. Even more surprising, their size doesn’t simply follow the twist pattern but peaks at a specific angle. This twist-controlled magnetism could pave the way for low-power spintronic devices built from geometry alone.

Mooraboolomyces wintlei C.P. Hull, A.S. Urquhart & A. Idnurm, in Hull, Urquhart et Idnurm. 2024. DOI: doi.org/10.11646/phytotaxa.644.1.5 Researchgate.net/publication/379691732AbstractA new genus and species in the Mucoromycota, Mooraboolomyces wintlei, was isolated into culture from leaf litter from a national park in Victoria, Australia, and is described. The strain reproduced asexually to form sporangia and sporangiospores, with no production of zygospores, and sequencing of its genome and analysis supported a heterothallic mode of reproduction. Phylogenetic analyses using five DNA regions placed the strain within the Mucorales and Mucoraceae, clearly distinct from previously described genera. This represents the second genus in this phylum that has been identified from Australia and that is currently unique to this country.biodiversity, heterothallism, Mucorales, sex locus, zygomycete, Fungi Physical properties of Mooraboolomyces wintlei.A.
