Long‐Term Storage of Meteoric Water in the Variscan Basement: Stable Isotope Constraints (δD–δ18O)

open access: yesTerra Nova, Volume 38, Issue 2, Page 116-123, April 2026.
ABSTRACT F‐Ba‐Pb‐Zn (±Ag) deposits near the unconformity between the Armorican and Aquitaine basins formed by mixing surface waters and brines with fluid ascending from the basement. To better constrain the source of this fluid and the conditions of mixing, we analyzed the hydrogen (δDwater) and oxygen (δ18Owater) isotopic composition of water trapped ...

Hydrocarbon Accumulation Model Controlled by Overpressure Evolution in the Kelasu Thrust Belt of the Kuqa Depression, NW China

open access: yesLithosphere, 2022
The Kuqa Depression is the most representative overpressured hydrocarbon accumulation area in western China. The early rapid subsidence since 5 Ma and the strong uplift in the late period have led to a complicated evolution history of the overpressure ...

Effect of 40 Hz Light Stimulation on Calcium Dynamics of Astrocytes

open access: yesAdvanced Photonics Research, Volume 7, Issue 3, March 2026.
40 Hz invisible spectral flickering (ISF) visible light stimulation and continuous light trigger calcium dynamics in primary astrocytes but recruit different signaling pathways. Astrocytes are glial cells with intracellular calcium dynamics essential for brain homeostasis, synaptic modulation, and cognition and altered in neuropathology and ...

Orbital and eustatic control of basin hydrology during the first stage of the Messinian Salinity Crisis

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
The paleo‐hydrology of the Sorbas Basin (SE Spain) and the wider Mediterranean region during the deposition of the Primary Lower Gypsum (PLG) stage of the Messinian Salinity Crisis, from ~5.97 to ~5.60 Ma, was affected by tectonics, precession‐forced climate oscillations, and eustatic sea‐level change.

Diagenetic effect of mantle-derived CO2 charge to clay minerals in the Baiyun-Liwan deepwater area of the Pearl River Mouth Basin in South China Sea

open access: yes地质科技通报, 2021
During petroleum exploration in the Baiyun-Liwan deep-water area of the Pearl River Mouth Basin (PRMB), South China Sea, a huge number of CO2 gas reservoirs has been met. Therefore, how to avoid the high CO2 risk has become a big challenge now.

Photothermally Powered 3D Microgels Mechanically Regulate Mesenchymal Stem Cells Under Anisotropic Force

open access: yesAdvanced Materials, Volume 38, Issue 2, 8 January 2026.
The photothermally powered microgel is designed to mechanically train mesenchymal stem cells using spatially patterned exogenous forces in three‐dimensional (3D) workspaces. When microgels are activated selectively via photothermal actuation, locally confined tens of nN forces are exerted on cells, triggering osteogenic differentiation in encapsulated ...
