Discoveries and experiments that change our picture of the world and the technology of the future.

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.
Aluminum projectiles hit a diamond composite at up to Mach 8.45; parts of it turned to graphite within microseconds, dispersing impact energy, the authors report.
In a laboratory test, Chiba researchers split one 8 mm × 8 mm CVD diamond along the {100} plane after four steps of 10 ps laser pulses.
A SLAC-led team published in Science X-ray scattering data showing a chiral signal in MnTe, which a conventional antiferromagnet should not produce.
Oak Ridge National Laboratory squeezed small crystals of manganese telluride and iron sulfide between titanium plates and recorded changes in magnetic domains and the anomalous Hall effect.
Researchers from MIT and the University of Delaware used flexible charged ligands instead of rigid ones, controlling bonds per nanoparticle in laboratory experiments.
Chinese and US groups report that spinodal decomposition in Au50Ag20Cu30 raises elastic modulus and hardness together; nanoindentation and simulations agree.
After a 42-year search, the LHCb collaboration saw the rarest beauty-particle decay yet recorded at the LHC. The result is consistent with the Standard Model.
A submicron graphene device produces a transverse thermoelectric voltage at zero magnetic field, without cooling, the authors report; it is a laboratory demonstration.
Metadynamics simulations and high-pressure, high-temperature synthesis show scale-dependent pathways of diamond nucleation from carbon precursors of different dimensionality.
The KM3NeT collaboration set new limits on Lorentz invariance violation using 1.4 years of data from six ORCA detection units, including first direct limits for muon and tau neutrinos.
University of Manchester scientists report evidence of a decay expected in one of 10 billion beauty particles. At 3.2 sigma, it is short of the 5 sigma discovery threshold.
The first six detection units of the KM3NeT/ORCA telescope set new limits on a Lorentz invariance violation model, without assuming the flavour ratios of astronomical neutrinos.
Oxford and Madrid groups showed that APLF bridges DNA ends only when at least two Ku70/Ku80 heterodimers are threaded onto each end, which limits bridging to DNA-bound Ku.
A focused laser sets oxygen content point by point in a high-temperature superconductor, switching regions between superconducting and insulating states.
Exciton polaritons in an organic microcavity with liquid crystal showed stripes and vortices at room temperature; the superfluid part still needs quantitative checks.
A British-German team used the spectra of 151 white dwarfs to model how the human eye would see them. Most are white; a few show green, pink or red surfaces.
An international team using Parker Solar Probe data found that the preferred rotation of turbulent magnetic fields flips where fluid-like plasma behavior gives way to particle dynamics.
