Platelet‐Rich Fibrin Induces New Bone Formation to Promote Extreme Lateral Interbody Fusion of Spine in Rabbits

open access: yesJOR SPINE, Volume 9, Issue 2, June 2026.
Preparation process of PRF and its promotion of intervertebral fusion. The rabbit lateral fusion model proves that PRF can promote the intervertebral fusion rate of allograft bone. In vitro experiments can be observed that PRF promotes the osteogenic expression of BMSCS.

Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Design, development, and test of a laser velocimeter for a small 8:1 pressure ratio centrifugal compressor [PDF]

open access: yes
The instrument was designed as a diagnostic tool for the basic fluid dynamics of the inducer, impeller, and diffuser regions of this type compressor. The LV instrumentation was optimized to measure instantaneous velocities up to approximately 500 m/s ...

Magnetic Rope Is an Electron Selector: Discovery in Space and Conceptual Application to Medicine

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Magnetic rope is a helical structure existing ubiquitously in astrophysical and space plasmas. Such structure has been conventionally known to accelerate electrons, convert energy, and play key roles in driving solar eruptions. Here, in contrast to the conventional concept, we report that the magnetic rope can divert electrons efficiently in ...

Performance of a low-pressure-ratio centrifugal compressor with four diffuser designs [PDF]

open access: yes
A low-pressure-ratio centrifugal compressor was tested with four different diffuser configurations. One diffuser had airfoil vanes. Two were pipe diffusers. One pipe diffuser had 7.5 deg cone diffusing passages.

Exploring Passive Permeability Profiles of Cyclic Heptapeptide Chemical Space Uncovers Bioactivity of Mortiamide Scaffold Driven by Colloidal Aggregation

open access: yesChemBioChem, Volume 27, Issue 9, 14 May 2026.
A comprehensive stereochemical and physicochemical survey of cyclic heptapeptide chemical space reveals that the mortiamide natural product scaffold possesses intrinsically low aqueous solubility and forms amyloid‐like fibril aggregates. Multiple orthogonal assays demonstrate that the observed cytotoxicity arises from colloidal aggregation rather than ...
