The physical validity of the mechanism proposed by the author is discussed. According to the theory a prolonged exposure to weak electromagnetic fields leads to an enlargement of the micro-bubbles and degassing of bioliquid. Degassing alters the physical and chemical properties of bioliquid that affect some medical and biological indicators. The following changes in some blood parameters during degassing in vitro were analyzed: a decrease in the glucose concentration, an abnormal activation of blood clotting, an increase in the rate of blood cell aggregation, a decrease in the effectiveness of aspirin as an inhibitor of platelet aggregation and the slowing of indirect anticoagulants. All of this evidences a possible correlation between the increasing electromagnetic pollution and the risk of cardiovascular disease.

The fabrications of circularly polarized luminescent (CPL) material are mainly based on the chemical and physical strategies. Controlled biosynthesis of CPL-active materials is beset with difficulties due to the lack of bioactive luminescent precursors and bio-reactors. Enlighted by microbe-assisted asymmetric biosynthesis, herein, we show the in situ bacterial fermentation of Komagataeibacter sucrofermentants to fabricate a series of bacterial cellulosic biofilms with CPL of green, orange, red, and near-infrared colors.

However, the limited TH signal intensity still restricts practical applications due to the inherently small nonlinear coefficient in material and relatively weak confinement of the pump electromagnetic field. Here, we present the enhancement of TH signals in the isotropic Si nanosphere and the Au core/Si shell nanosphere exhibiting anapole mode excited by tightly focused radially polarized beams.

Non-covalent protein-protein interactions are one of the most fundamental building blocks in cellular signalling pathways. Despite this, they have been historically hard to identify using conventional methods due to their often weak and transient nature. Using genetic code expansion and incorporation of commercially available unnatural amino acids, we have developed a highly accessible method whereby interactions between biotinylated ubiquitin-like protein (UBL) probes and their binding partners can be stabilised using ultraviolet (UV) light-induced crosslinks.

We have systematically studied the electromagnetic transport properties of PbTe thin films under gate voltage modulation. The system demonstrates pronounced electron-electron interactions exclusively within the gate voltage range where only hole carriers are present. Furthermore, the Berry phase is utilized to qualitatively elucidate the transition between weak antilocalization (WAL) and weak localization (WL) through the regulation of gate voltage and temperature.

Two-dimensional van der Waals (2D vdW) materials have attracted widespread research interest due to their unique physical properties and potential application prospects. In this study, an atomistic-level dynamical simulation method is employed to investigate the chirality of antiferromagnetic resonance modes in CrI bilayer. Beyond the typical observations of a linear increase in high-frequency resonance mode and a linear decrease in low-frequency resonance mode, we have identified a distinct magnetization precession chirality in the CrI bilayer at low magnetic fields: Spins in different layers exhibit opposite precession chirality.
