QLEDs â light-emitting diodes that rely on nanocrystals called quantum dots â are usually made with toxic heavy metals. A strategy has been developed to make QLEDs with a performance comparable to that of commercially available technologies but using a more environmentally friendly alloy of zinc, selenium, telluriu

The Earth’s puzzling deep water cycle - Nature Geoscience
5+ day, 17+ min ago (190+ words) Nature Geoscience (2026) Cite this article The minerals needed to transport water into the deepest parts of the Earth’s mantle remain unclear. High-pressure and -temperature experiments conducted at lower-mantle conditions suggest that iron oxyhydroxide phases may be important to such transport....
Black carbon warms more strongly in aerosol-rich air - Nature Geoscience
2+ week, 5+ day ago (205+ words) Nature Geoscience (2026) Cite this article Coatings on black carbon particles modulate their warming potential. A decade of global single-particle observations shows that the amount of coating scales with the ratio of particulate matter smaller than 2.5 μm in diameter to black…...
Cell transplant across the tree of life hints at how animals emerged
2+ mon, 3+ week ago (274+ words) Embryonic ‘organizer cells’ can tell embryos of various phyla what kind of body to build. Embryonic ‘organizer cells’ can tell embryos of various phyla what kind of body to build....
Tracking hydrogen migration in iron under Earth’s core conditions - Nature Geoscience
2+ mon, 4+ week ago (269+ words) Nature Geoscience (2026) Cite this article Time-resolved X-ray diffraction experiments in a laser-heated diamond anvil cell suggest that hydrogen in iron hydride becomes highly mobile at Earth’s core pressures and high temperatures. The measurements provide experimental indications of a superionic state…...
Experimental indications of superionic behaviour in iron hydride under Earthâs core conditions | Nature Geoscience

Superheating in mafic magmas controls clinopyroxene nucleation delay and magma ascent dynamics - Nature Communications
3+ mon, 5+ day ago (1697+ words) Experimental conditions of (A) in situ and (B) ex situ view experiments reported as function of temperature and time. Dashed line shows clinopyroxene liquidus temperature calculated using Rhyolite-MELTS software63,64 and experimentally constrained. Clinopyroxene liquidus temperature is calculated for the tephrite with 1 wt.% H2O. Differential…...
Characterization of newly identified N–S shear zones in the Egyptian Nubian Shield by integrating geophysical, remote sensing and field data - Scientific Reports
3+ mon, 2+ week ago (1786+ words) The NED is characterized by its unique composition of Ediacaran igneous rocks, which sets it apart from the CED and SED. It lacks ophiolites, has unidentified BIF and diamictite, shows no evidence of Najd deformation, and features a significant presence…...
The global distribution of CO2-rich magmas is determined by lithospheric thickness - Nature Geoscience
3+ mon, 3+ week ago (1751+ words) Nature Geoscience (2026) Cite this article Metasomatized lithospheric mantle plays a critical role in the petrogenesis of CO2-rich magmas, which are important hosts of rare-earth element deposits. However, the relationship between the structure of the lithosphere and the global distribution of…...
