Meteorological conditions characteristic of anthropogenic glaciation of supercooled liquid-water clouds and of anthropogenic CCN perturbations on clouds [PDF]

open access: yes
We used ERA5 atmospheric reanalysis data to characterise the meteorological conditions characteristic of anthropogenic glaciation of supercooled liquid-water clouds and of cloud perturbations induced by anthropogenic cloud condensation ...

G6PC Downregulation Promotes Renal Calcium Oxalate Stone Formation via Lactate‐Induced SNAIL1 K206 Lactylation and Epithelial‐Mesenchymal Transition

open access: yesAdvanced Science, EarlyView.
In renal calcium oxalate stone formation, G6PC downregulation leads to lactate accumulation. This lactate mediates CBP/p300‐dependent lactylation of SNAIL1 at K206, promoting its nuclear translocation. Nuclear SNAIL1 activates the TGF‐β/SMAD3 pathway, driving epithelial‐mesenchymal transition and fibrosis, which ultimately facilitates crystal ...

Far-field modelling of THM processes in rock salt formations

open access: yesOpen Geomechanics
Glaciation cycles are one aspect to be considered in assessing the safety of deep geological repository sites for long-term radioactive waste storage. This study examines the impact of time-dependent boundary conditions and thermo-hydro-mechanical (THM)

Pleistocene Glaciations

open access: yes, 2018
It is estimated that the global average of Earth’s surface temperature was about 8°C higher than today when the Cenozoic Era started about 66 Ma ago (1 Ma = 1 million years) (Zachos et al. 2001; Zachos et al. 2008). As shown in Chapter 1 (Figure 1.1), the history of the Cenozoic is rather shaky.

A Disaggregation Strategy for Nanopesticide Fabrication: Investigating the Impact of Nanosizing on Pesticide Biointeractions

open access: yesAdvanced Science, EarlyView.
To explore the impact of nanosizing on pesticide biointeractions, a 7‐nm (average) emamectin benzoate nanopesticide without nanocarriers or surfactants is fabricated via HOAc‐mediated disaggregation. Nanosizing enhances bioactivity against Megalurothrips usitatus and Meloidogyne enterolobii and improves plant penetration.

Intrinsically Mitochondria‐Targeting Nanozyme via Coordination‐Assembly of Natural Quercetin for Cascade Antioxidant Therapy of Cerebral Ischemia‐Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
This study uncovers that quercetin naturally targets mitochondria. By coordinating quercetin with Fe3+, we engineer an ultrasmall cascade nanozyme (MCN) with superoxide dismutase‐catalase activities. MCN crosses the damaged blood–brain barrier, scavenges mitochondrial ROS, prevents mitochondrial DNA leakage, and blocks the cGAS‐STING pathway, thereby ...

A multi-dating approach applied to proglacial sediments attributed to the Most Extensive Glaciation of the Swiss Alps [PDF]

open access: yes, 2010
The number and the timing of Quaternary glaciations of the Alps are poorly constrained and, in particular, the age of the Most Extensive Glaciation (MEG) in Switzerland remains controversial.
