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 ...

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.

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.

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 ...

Fluid Inclusion Stratigraphy and Multistage Hydrocarbon Evolution in the Risha Gas Field, Jordan

open access: yesGeofluids, Volume 2026, Issue 1, 2026.
An integrated fluid inclusion stratigraphy (FIS) and petrographic analysis of the RH‐3 well in the Risha Gas Field, Jordan, reveals a highly compartmentalized vertical fluid column. The upper section (1200–1750 m) is dominated by wet‐gas to gas‐condensate fluids, transitioning to dry gas below 1850 m.
