Correlative SHG-AFM imaging workflow for label-free quantitative analysis of collagen structure-function relationships
We present a user-friendly correlative second harmonic generation (SHG) and atomic force microscopy (AFM) imaging workflow for quantifying the nanomechanical properties of collagen in unfixed, unlabeled tissue sections. SHG Aligned Profiling for Elasticity and Segmentation or SHAPES utilizes SHG imaging to guide AFM force mapping, enabling label-free, anatomically specific selection of regions of interest, facilitating spatially resolved characterization of fibrous collagen morphology and...
Saturated and Anisotropic Magnetostriction in an Altermagnet
arXiv:2605.30773v1 Announce Type: cross Abstract: Magnetostriction, a fundamental phenomenon bridging magnetism and mechanics, has enabled a broad spectrum of applications. For almost two centuries, it has been mainly investigated for ferromagnets. Regarding the magnetostriction of antiferromagnets (AFMs), limitedly known examples for both conventional collinear AFMs and noncollinear AFMs predominantly exhibit non-saturating magnetic-field dependence.
Demonstrating magnetic memory in iron-rhodium structures using a quantum diamond microscope
arXiv:2606.03738v1 Announce Type: cross Abstract: Iron-rhodium (FeRh) has a first-order phase transition near room temperature between antiferromagnetic (AFM) and ferromagnetic (FM) phases, making it a promising material for magnetic memory technologies like heat-assisted magnetic recording (HAMR). It has a comparatively sharper phase transition and lower writing temperature than alternative materials, implying less thermal engineering constraints and an increase in write/read head lifetime....
High-Temperature and High-Speed Atomic Force Microscopy Using a qPlus Sensor in Liquid via Quadpod Scanner and Hybrid-Loop Frequency Demodulation
arXiv:2604.04970v2 Announce Type: replace Abstract: Atomic-resolution imaging on molten metal/solid interfaces at temperatures above 200 {\deg}C was achieved using a high-temperature, high-speed atomic force microscope (AFM) equipped with a qPlus sensor. A tip-scanning high-speed Quadpod scanner for a large mass load of qPlus sensor (2.3 g) was developed to enhance thermal drift tolerance by high-speed scanning and thermal insulation from the heated specimen. This scanner has dominant...
Apple partnering with Google and Nvidia for most advanced AI model
Apple on Monday revealed what it's been working on in artificial intelligence at its annual Worldwide Developers Conference in Cupertino, Calif. WWDC showed off demos of its redesigned Siri, which can speak back and forth with the user, a major improvement over previous versions of the assistant. In a demo, Siri was able to check concert dates, set a reminder to buy tickets, and even get directions to pick up a friend on the way to the concert venue. But the announcement also highlighted...
Magnetic Tweezers Experiments Reveal Increased Mechanical Sensitivity of the F2561Y Mutant in Von Willebrand Factor
The large glycoprotein von Willebrand factor (VWF) is essential for primary hemostasis. By sensing hydrodynamic forces in the bloodstream, VWF elongates under elevated shear, increasing its adhesiveness to platelets. This mechanosensitive behavior arises from its multidomain architecture, where distinct structural elements respond at different force scales.
Control of Electrons Spin Eliminates Hydrogen Peroxide Formation During Water Splitting
arXiv:2606.01648v1 Announce Type: new Abstract: The production of hydrogen through water splitting in a photoelectrochemical cell suffers from an overpotential that limits the efficiencies. In addition, hydrogen-peroxide formation is identified as a competing process affecting the oxidative stability of photoelectrodes.
Aluminum oxide's irregular atomic surface explains its low reactivity
Aluminum oxide's irregular atomic surface explains its low reactivity Gaby Clark Scientific Editor Robert Egan Associate Editor Why do certain surfaces behave very differently from what theoretical calculations suggest? Scientists long assumed that the aluminum oxide surface should be highly reactive and capable of splitting water molecules. In experiments, however, this behavior is barely observed.
Acute flaccid paralysis and myelitis (AFP/M) in England
Acute flaccid paralysis and myelitis (AFP/M) in England Data up to 2025 on acute flaccid paralysis and myelitis in England (AFP/M). Applies to England Documents Details Key points Ten AFP/M cases not explained by a non-infectious cause were notified to UKHSA in England in 2025; 8 of which were in children under 15 years of age. Historically, AFP/M reporting levels have been low, with potential under-ascertainment.
