A laser-treated, glassy layer at the electrolyte interface improved the stability of solid-state lithium-metal batteries. In tests, the cells cycled for more than 2,000 hours, while lithium-cobalt-oxide cells retained a capacity of 101.9 mAh per gram after 800 cycles at 4.5 volts.
People can interpret the same general statement in different ways, yet generic language may still pass on broad knowledge. Across three experiments, a model in which such statements have an uncertain threshold best explained participants’ varied interpretations of new generic claims.
Some black holes in the early universe appear unusually massive compared with the galaxies around them. A modelling study suggests that brief, repeated bursts of rapid feeding, triggered by major galaxy mergers, could explain this pattern and the brightness of some active black holes seen by JWST.
Researchers developed an AI-based method for reconstructing changing radio images of black-hole jets as continuous videos. Applied to repeated observations of the blazar 3C 345, it estimated the local, instantaneous motion of plasma rather than tracking only separate jet features.
China’s expansion in electric vehicles illustrates the goals and progress of its Dual Circulation Strategy, according to a study in Asia Europe Journal. The authors conclude that the European Union needs a multilayered industrial strategy, including more production and innovation at home, to compete with China.
Doctors used ultrasound, gentle larval removal and DNA sequencing to diagnose a rare Hypoderma sinense infestation in a child from a cattle-raising region of China. The case shows how this livestock-associated parasite can resemble common skin infections.
In trained mice, deep-layer neurons in the auditory cortex developed categorical responses to sounds that differed in their temporal rate. These neurons also carried strong signals related to the animals’ choices, linking sound classification with behavior.
A study found that increases in online mentions of the Benadryl Challenge were followed by a significant rise in adolescent-related calls to US poison centers about diphenhydramine. Those calls remained elevated for more than 25 days after the first spike in online mentions.
Astronomers have confirmed six dense groups of young galaxies from about 2.4 to 3.1 billion years after the Big Bang and reconstructed their three-dimensional structures. Galaxies in the densest regions showed brighter hydrogen emission and fewer faint emitters than galaxies in less crowded surroundings.
A study in Nature Communications identifies a conserved group of plant genes that produces small RNAs involved in defense against fungal and oomycete pathogens. In Arabidopsis, these genes are clustered together and have diversified through duplication, sequence changes and gene loss.
A new framework suggests that the supermassive black holes seen less than 700 million years after the Big Bang may have begun as unusually large seeds. It makes testable predictions for observations with the James Webb Space Telescope and future gravitational-wave detectors.
Five daylong recordings offer a detailed look at young children’s language environments, while also showing the practical and theoretical difficulties of studying them. The researchers outline a workflow for manual transcription and annotation and report four insights that could shape future research methods.
A systematic review and meta-analysis examined reported eye and neurologic complications after facial dermal filler injections in 81 patients across 16 studies. Among these reported patients, permanent vision loss and brain infarction were observed in substantial proportions, but the analysis does not show how often these complications occur among all filler procedures.
The MAJIS instrument aboard the European Space Agency’s JUICE spacecraft performed well during its August 2024 Earth-Moon gravitational assist. Tests supported its updated wavelength calibration and showed that its brightness measurements were close to expected values, strengthening confidence in future observations around Jupiter.
Two studies of active gamers suggest that returning smoothly from gameplay to daily life is linked to better mood, vitality and life satisfaction, and to fewer symptoms of gaming disorder. The findings point to a way of studying escapism that looks beyond why people play to what happens when they stop.
