Metalorganic Titanium Treatment to Change Enamel Optical Properties

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 9, September 2026.
ABSTRACT Observational studies have shown that human teeth with higher concentrations of titanium traces have better optical properties. The aim of this study was to investigate how titanium ion infiltration into tooth enamel affects its optical properties by studying the diffusion and reactivity of titanium compounds in tooth enamel and how this ...

A dual role of phycoerythrin in the nitrogen‐fixing cyanobacterium Crocosphaera watsonii: From light‐harvesting to nitrogen reservoir

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Unicellular diazotrophic cyanobacteria contribute up to ~50% of marine N2 fixation, and Crocosphaera watsonii, characterized by high phycoerythrin (PE) content, is among one of the key species in tropical and subtropical oceans. Although recent observations have revealed heterogeneous N2 fixation activity within C.

Wavelength and Full‐Polarization Encrypted Orbital Angular Momentum Meta‐Holography

Laser &Photonics Reviews, Volume 20, Issue 17, 3 September 2026.
By multiplexing three independent degrees of freedom of light, a single‐layer geometric‐phase metasurface encrypts 24 distinct holographic images across 3 wavelengths, 12 pairs of orthogonal polarizations, and 4 OAM channels, taking advantage of axial chromatic dispersion to reconstruct the color images at the same plane. ABSTRACT Multiplexing multiple

Something New Under the Sun: Assessing the Relative Influence of Sunlight Irradiance and Temperature on Activity Patterns in a Conspicuous Dragonfly

New Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
In amberwing dragonfly (Perithemis tenera), solar irradiance in the 550–700 nm range (orange arrows) is only reflected by the colored wings of males (fully orange individuals). Therefore, sunlight intensity may be an important factor driving the effectiveness of their conspicuous wing displays during territorial contests and mating behavior.

A Label‐Free Ultraviolet Photoacoustic Microscopy Enables Nuclear Imaging and Toxicity Assessment in an Intact Brain Organoid

Small, Volume 22, Issue 51, 11 September 2026.
Ultraviolet photoacoustic microscopy enables label‐free visualization of nuclear morphology in intact human brain organoids. By exploiting endogenous nucleic acid absorption at 266 nm, this approach resolves individual nuclei without staining or sectioning.
