A study in The Innovation, based on a century of observations and model experiments, links the Atlantic Niño's effect on winter ENSO to tropical sea surface temperature gradients.
Researchers at Northwestern Polytechnical University changed the solidification of eutectic high-entropy alloys with trace carbon, in arc-melted laboratory ingots.
Teams from Shanghai and Westlake University encoded data in spatiotemporal topological states of ultrafast pulses, a proof-of-concept for turbulence-tolerant optical links.
With Run 1 and 2 data the significance is 3.2σ. The most precise Bs0→μ+μ– branching fraction and effective lifetime to date also agree with the Standard Model.
Archaeologists at Bournemouth University reinterpret the name, coin title and coin imagery of Verica, a ruler of the Atrebates in Iron Age Britain, as evidence of a female ruler.
Cryo-EM showed phage protein L05 assembles into a 9.5-megadalton particle, which could give researchers a simpler way to study vaults in human cells.
Researchers at Cardiff University and the National Museum of Wales determined the four-letter combination without touching the lock, using micro-CT imaging.
The California Insect Barcode Initiative reports that only about two-thirds of the state's insect species are described; over one million specimens were DNA barcoded.
The orbiter's spectrometers recorded hydrogen chloride in a season when it is normally absent; the team links it to fissures, but active volcanism is not proven.
An experimental toothbrush with PVDF filaments generates a charge that produces reactive oxygen species against oral bacteria. Lab and three-month human tests were reported.
Measurements from a research cruise show that Subantarctic Mode Water and Antarctic Intermediate Water enrich in nutrients differently as they move north for decades.
Jilin University and Changchun Institute of Applied Chemistry modified a carbon nanotube cathode to curb iodine shuttling in an aqueous zinc battery; a pouch-cell prototype was also built.
Sequencing of ancient DNA revealed a previously elusive population that entered Sweden by about 4,000 years ago, roughly 800 years later than the traditional date for Germanic's arrival.
Authors found that specific codon pairs cause −1 ribosomal frameshifting mainly in cancer cells and used it to switch on a pyroptosis gene in mouse tumour models.
A correlative X-ray method combining phase-contrast CT and small-angle scattering mapped nano- and microscale strain in intact rat discs under load.
Physics-based processing of archival JWST coronagraph images removed residual starlight and revealed the giant planet 51 Eridani b, which conventional processing missed.
Chemists at the Shanghai Institute of Organic Chemistry isolated copper–heteroaryl sulfone complexes that cleave a C–S bond under visible light, producing alkyl radicals.
Models of mantle flow over the past billion years predict long uplift, then subsidence, of Laurentia, Baltica and North China. The authors say this fits the gap in the geological record.
University of Vienna researchers combined genomes with cave sediment DNA and found long-distance gene flow alongside regional continuity through the Last Glacial Maximum.
Authors analysed genome-wide data from 4,587 ancient individuals against four models of Celtic origin and favour a movement from eastern central Europe as the most parsimonious.
