Multiple Twinning in Nacre and Aragonite

open access: yesAdvanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
Electron backscatter diffraction map of a cluster of geologic aragonite, exhibiting single, double, and triple twins. The whole cluster is approximately 2 cm wide. Colors indicate crystal orientations, so that pixels where the a‐, b‐, and c‐axis is perpendicular to the image plane are green, red, and blue, respectively.

The Effect of Amino Acids on the Formation of Amorphous Calcium Carbonate Nanoparticles

open access: yesAdvanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
Biomineral formation often proceeds via the assembly of amorphous calcium carbonate (ACC) nanoparticles with narrow size distributions. Using in situ SAXS coupled to a stopped‐flow device, we follow synthetic ACC formation with a 10 ms time resolution and show that amino acids narrow the size distribution at low supersaturation, highlighting their key ...

Chiral Acoustic Phonon and Conservation of Pseudoangular Momentum in α‐Quartz

open access: yesAdvanced Materials, Volume 38, Issue 16, 17 March 2026.
Chiral acoustic phonons in α‐quartz are probed via Brillouin light scattering, exploiting the photon's helicity and the crystal's handedness. The interaction obeys a selection rule arising from pseudoangular momentum conservation, enabling direct optical access to phonon chirality in nonsymmorphic crystals.

When Error Propagation Fails: A Mini‐Tutorial on Geometric Brownian Motion Simulation

open access: yesAdvanced Theory and Simulations, Volume 9, Issue 3, March 2026.
Linear error propagation fails in multiplicative stochastic processes governed by geometric Brownian motion, severely underestimating variance and tail risk. This mini‐tutorial derives the exact log‐normal solution, implements Euler–Maruyama simulation, and introduces a quantitative diagnostic for when simulation is essential.

Magnetic Resonance Imaging Reveals Meningeal Lymphatic Impairment in Lung Adenocarcinoma Brain Metastasis Progression

open access: yesAdvanced Science, Volume 13, Issue 16, 18 March 2026.
This study demonstrates meningeal lymphatic impairment associated with lung adenocarcinoma brain metastasis progression in both human patients and mouse models, establishes clinically applicable non‐invasive imaging biomarkers for quantitative analyzing mLV structure and function, and reveals mLVs as robust prognostic indicators and promising potential
