Fibonacci Turbulence Two distinct classes of turbulence are studied through the lens of statistical physics, but a certain kind of discrete model bridges these classes and can describe both.

Investigating Lipid Headgroup Composition within Epithelial Membranes: A Systematic Review Membrane lipid composition is often quoted within the literature, but with very little insight into how or why these compositions vary when compared to other biological membranes. One prominent area that lacks understanding in terms of rationale for lipid variability is the human gastro-intestinal t...

Deep‐skin multiphoton microscopy in vivo excited at 1600 nm: a comparative investigation with silicone oil and deuterium dioxide immersion Multiphoton microscopy (MPM) excited at the 1700-nm window has enabled deep-tissue pe*******on in biological tissue, especially brain. MPM of skin may also benefit from this deep-pe*******on capabili...

Spintronics Meets Density Matrix Renormalization Group: Quantum Spin-Torque-Driven Nonclassical Magnetization Reversal and Dynamical Buildup of Long-Range Entanglement A synergy between strongly electron-correlated physics, quantum transport theory, and quantum information science provides a long-sought quantum-mechanical description of spin torque, an effect at the heart of spintronic research.

Thermophobic Leidenfrost We report that a volatile liquid deposited on a hot substrate with a gradient of temperature does not only levitate (Leidenfrost effect), but also spontaneously accelerates to the cold. This thermophobic effect is also observed with sublimating solids, and we attribute it to the ability of temperatu...

Interaction-Stabilized Topological Magnon Insulator in Ferromagnets Particle number nonconservation in interactions among magnons in ferromagnet models reveal a topological phase transition, which opens possibilities for energy-efficient magnetic information processing.

Physical theory of biological noise buffering by multicomponent phase separation The stochastic nature of transcription/translation implies that the concentrations of cellular proteins are “noisy” and not constant in time or across cell populations. Liquid–liquid phase separation (LLPS) can reduce or “buffer” this noise by maintaining well-defined concentrations, even ...

Spontaneous activity competes with externally evoked responses in sensory cortex Humans and animals recognize light tactile stimulations on some occasions while at others miss even stronger stimuli. The explanation of this apparent paradox lies in the competition between spontaneously and externally evoked responses in the brain. Brief bursts of beta-oscillations have been impli...

First experience in clinical application of hyperspectral endoscopy for evaluation of colonic polyps A new hyperspectral endoscope (HySE) was designed to enhance polyp discrimination for detection and resection. Spectra from three tissue types in seven patients undergoing routine colonoscopy screeni...
