Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Lactate inhibits glucose‐induced zigzag motility and enhances linear motility in bull spermatozoa by suppressing glycolysis

open access: yesAndrology, EarlyView.
Abstract Background Energy metabolism and substrate balance are critical determinants of sperm motility and fertility. Linear motility is necessary for sperm forward movement, whereas hyperactivated motility is a prerequisite for fertilization. The preference of metabolic pathways depends on substrate availability which controls sperm motility. However,

Full Crystallographic Imaging of Hexagonal Boron Nitride Monolayers with Phonon‐Enhanced Sum‐Frequency Microscopy

open access: yesAdvanced Materials, Volume 38, Issue 7, 2 February 2026.
A nonlinear optical microscopy technique is introduced that enables rapid imaging of hexagonal boron nitride monolayers, which are usually optically invisible. The nonlinear mixing of mid‐infrared and visible laser pulses enables full crystallographic imaging through phase‐resolved sum‐frequency generation microscopy, where the resonant excitation of a

A Van der Waals Material Exhibiting Room Temperature Broken Inversion Symmetry with Ferroelectricity

open access: yesAdvanced Science, Volume 13, Issue 9, 13 February 2026.
This study reports a βp$\ubeta^{\text{p}}$ phase of indium selenide showing ferroelectricity over large areas at room temperature in a low‐dimensional limit. It is found that indium selenide films with βp$\ubeta^{\text{p}}$ layers display electric field‐induced switchable polarization characteristic of ferroelectric materials, suggesting the breaking ...
