Researchers correlated X-ray maps of titanium oxidation state with local electrochemical probing of single Ti3C2Tx flakes; redox activity extended well beyond the point of contact.
Radiocarbon dating at 1 cm resolution revealed event layers in a 40 cm core that X-ray and CT missed; some match recorded earthquakes of the 13th–20th centuries.
A theoretical study from Japan's Institute for Molecular Science reproduces most of a puzzling infrared signal in a perovskite film without any change in molecular vibrations.
Researchers at UVSOR used phase-coherent extreme ultraviolet pulse pairs and watched interference fringe contrast fall over a few femtoseconds, tracking an inner-shell vacancy in xenon atoms.
A prototype at TU Wien locks a laser to thorium nuclei without a conventional atomic clock. Its precision is about 10^-15, still below the best optical atomic clocks.
A theoretical model from JINR with two collective parameters reproduced measured half-lives of isotopes from uranium to hassium, which differ by tens of orders of magnitude.
A Delft University of Technology team flipped the nuclear spin of a single atom even when it was largely disentangled from the electron spin, contrary to the authors' expectations.
Astronomers using the Gemini North telescope on Maunakea report a faint, tight pair of quasars, seen as it was during the epoch of reionization.
Researchers ruled out binary black holes of about 10 billion solar masses and above in two distant systems. These are the first gravitational-wave limits for so early an epoch.
In a retrospective Mayo Clinic study of 137 leads, awake surgery led to repositioning in about 15%; 88% of those changes could not have been made by imaging alone.
Researchers calibrated a low-cost digital camera to read the infrared electroluminescence of silicon modules and derive open-circuit voltage; tested on eight modules built 1978–2022.
A biomarker formed when GHB binds a sugar stays detectable after the drug itself falls below the threshold. The method is already used in routine laboratory work at the University of Zurich.
Intensity cycling added to transient scattering microscopy isolates single-particle transport in van der Waals semiconductors and tracks exciton–exciton annihilation in lab experiments.
A review in The Innovation says high-spectral-resolution lidar on China's DQ-1 and Europe's EarthCARE replaces assumptions with measurement of subsurface plankton.
Researchers at IR Sant Pau found elevated neurofilament light chain in carriers of the Huntington's mutation before symptoms or brain atrophy. Current staging criteria cannot distinguish these cases.
More than 160 researchers ran a coordinated camera-trap survey in 2021 and 2022. The open dataset holds 94,441 mammal observations and 5024 bird detections.
A prototype speckle spectrometer built around an integrating sphere resolves 6 fm at 780 nm, about 80 times finer than earlier speckle devices, and measured rubidium hyperfine structure.
Authors of the FLIP method report 2–15 times better sensitivity on JWST NIRCam coronagraph data and the first detection of 51 Eridani b at 4.3 μm.
The 2024 first campaign of the ALPS II light-through-a-wall experiment saw no signal, yet the setup set a new sensitivity record for laboratory axion searches.
Construction of the detector module cryostats for the DUNE neutrino experiment began underground in South Dakota. The detectors are planned to receive a beam from Fermilab by 2031.
