This theoretical biophysics study models the radical pair mechanism as an open quantum system to derive an explicit dependence of magnetic-field effects on the spin coherence relaxation time (τ) and chemical kinetics (k). It reports a condition under which RPM effects become significant and estimates τ in…

This article is a commentary on how emotions and community dynamics can bias scientific reasoning when a favored hypothesis becomes a "ruling hypothesis." Using animal magnetoreception as an example, it argues that radical-pair/cryptochrome-centered frameworks may sometimes be treated as dominant, potentially leading…

This study compares PBMC cryopreservation using an electromagnetic field (EMF) freezer versus standard slow-freezing (SLF). It reports equivalent viable cell number, viability, and cell activity between methods. EMF freezing required substantially less time (0.25 h vs 3 h), which may improve operational efficiency by…

This in vitro/ex vivo study tested whether different magnetic-field configurations alter ketoprofen properties and its transdermal delivery in porcine skin using Franz diffusion cells. The authors report no change in ketoprofen molecular structure, but subtle changes in crystal structure and physicochemical…

This engineering study evaluates electromagnetic field (EMF) treatment as a nonchemical method to control gypsum and silica scaling in reverse osmosis using synthetic brackish water and real RO concentrate. It reports EMF altered gypsum crystal morphology to form a more porous scale that was easier to remove with…

This ex vivo study tested whether different magnetic-field modalities change transdermal delivery of naproxen through pigskin. Rotating magnetic fields (RMF) at 50 Hz produced the greatest increase in permeation metrics versus a no-EMF control, while negatively polarized static fields reduced permeation.…

This paper examines the radical pair mechanism in cryptochrome, focusing on the tightly bound FAD–superoxide radical pair. It reports that, contrary to traditional expectations, such a closely bound radical pair can show sensitivity to Earth-strength magnetic fields if recombination is strongly asymmetric, invoking…

This study examined whether exposing maize seeds to electromagnetic fields (23, 70, 118 μT) for 15 days alters physicochemical properties of starch isolated from the resulting grains. SEM and X-ray diffraction results suggest starch morphology and orthorhombic crystalline structure were largely unchanged, though…

This materials proof-of-concept study explored using radiofrequency EMF to heat magnetic nanoparticles dispersed in PLLA to modulate polymer properties. Heating was monitored by infrared camera, and polymer changes were assessed by differential scanning calorimetry and nanoindentation. The authors report that EMF…

This in vitro materials study compares microwave irradiation versus conventional water-bath heating for synthesizing HPMC-graft-(PVA-co-acrylic acid) hydrogels loaded with captopril. The authors report that microwave-synthesized hydrogels had more uniformly porous structures and higher swelling ratios, with…

This engineering study deposited Ga-doped ZnO thin films via radio frequency sputtering and examined how Ga content affects optoelectronic properties and electrical stability. The abstract reports non-monotonic changes in conductivity with increasing Ga content alongside degraded crystallinity, while maintaining >80%…

This materials study examines how a high magnetic field affects crystallization during isothermal annealing of [(FeCo)BSi]Nb4 bulk metallic glass. The authors report that the field promotes α-(Fe,Co) precipitation and suppresses boride formation, yielding a nanocomposite microstructure with α-(Fe,Co) dispersed in an…

This materials study used optical second harmonic generation to detect electric field-induced structural changes at Pt/Fe-doped SrTiO3 anode interfaces. Reduced crystals showed steadily increasing susceptibility with increasing negative voltage, interpreted as electrostriction-related bond distortions. Oxidized…

This animal organ-preservation study compared 12-hour porcine heart preservation at -3°C using a device generating a variable magnetic field versus conventional 4°C preservation. The subzero variable-magnetic-field condition showed higher myocardial ATP, lower lactate, and less mitochondrial ultrastructural damage…

This engineering/materials study examined how RF magnetron sputtering power affects the structural and optical properties of In2S3 thin films intended as a CdS buffer substitute in CIGS solar cells. Films deposited at 60–120 W were characterized using XRD, AFM, EDS, and UV-visible spectrophotometry. The films were…

This study models nematic liquid crystals embedded in random polymer networks, where disorder disrupts long-range order and produces a glassy state. It uses simulations and an Imry-Ma-like analytic approach to visualize domains, predict domain size, and calculate the response to an applied electric field. The authors…
