Siliceous sponges or seawater as a silicon source? Tracing silicon burial pathways of the Upper Cretaceous opal‐CT deposits using δ30Si and δ7Li

Sedimentology, EarlyView.
ABSTRACT Classical models of formation of sedimentary siliceous rocks (flint, chert, opoka) commonly assume that the Cretaceous marine silicon (Si) cycle was primarily biologically controlled, broadly analogous to the modern ocean. In this framework, siliceous sponges are regarded as the principal source of dissolved silica (dSi) to sediment porewaters,

Scaling temporal resolution from mice to humans: Challenges and innovations in preclinical imaging of translational models

The Journal of Physiology, EarlyView.
Abstract figure legend Temporal scaling physiology differs significantly between mice and humans. Mice have higher metabolism, heart and respiratory rate, as well as faster blood flow rates, brain activity and physiological dynamics over time. These differences influence the temporal resolution needed in preclinical imaging of mouse models to ...

Machine‐Learning‐Enabled Wood with Nanopump Functionalization for Solar Interfacial Evaporation

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
This study employed machine learning to design an iron‐cobalt‐carbon‐wood photothermal material, achieving high‐efficiency evaporation at 2.807 kg m−2 h−1 and excellent salt resistance. The integrated system increased the daily water production efficiency of solar distillation by 1.5 times, providing an innovative solution for sustainable seawater ...
