Advanced Science, EarlyView.In rheumatoid arthritis, synovial Tregs accumulate but are functionally impaired due to iron overload‐induced ferroptosis. This triggers mitochondrial dysfunction and TXK tyrosine kinase‐mediated signaling, leading to Treg destabilization and inflammation.

Double Reflections in Polarized Radar Data Reveal Ice Fabric in the North East Greenland Ice Stream
Geophysical Research LettersThe orientation of ice crystals within large ice masses has a strong influence on their mechanical properties, but cannot be directly observed from the surface.

Ice flow in the northeast Greenland ice stream [PDF]
Annals of Glaciology, 2000 AbstractWe have measured ice flow and detailed topography in northeastern Greenland using satellite-based synthetic-aperture radar (SAR) interferometry. The subject of this study is the large ice stream that drains this quadrant of the ice sheet. A single SAR interferogram allows the measurement of one component of motion over a several-day-long ...

Mild Focal Cooling Decouples Dendrites to Reconfigure Cortical Output
Advanced Science, EarlyView.Mild cooling of the cortical surface selectively modulates apical dendritic excitability, plasticity, and somato‐dendritic coupling, while uncoupling these effects from basal dendrites, and reshapes apical‐driven responses in barrel cortex during whisker touch.

Annals of Glaciology, 2017 Using observations of basal topography, ice thickness and modern accumulation rates, we use theory and a dynamic flowline model to examine the sensitivity of Antarctica's Foundation Ice Stream to changes in sea level, accumulation and buttressing at the ...

Ice-sheet surging and ice-stream formation [PDF]
Annals of Glaciology, 1996 A simplified model of ice-sheet behaviour is described. It combines the assumptions of rapid ice flow, high viscous activation energy and realistic sediment-based sliding dynamics to form a non-linear diffusion-type equation which can display relaxation oscillations analogous to those of surging glaciers, and which may be relevant to large-scale surges

Advanced Science, EarlyView.ABSTRACT Hydrogen sulfide (H2S) can be transformed into hydrogen (H2) through several chemical and catalytic processes, offering a promising route for both waste treatment and clean H2 production. This colorless, flammable, and toxic gas is found abundantly in swamps, volcanoes, hot springs, sewages, other natural gas fields, and even in refineries and

A viscoelastic model of ice stream flow with application to stick-slip motion
Frontiers in Earth Science, 2016 Stick-slip motion such as that observed at Whillans Ice Stream, WestAntarctica, is one example of transient forcing significantly affecting longer-termice-stream dynamics.

Radar-derived bed roughness characterization of Institute and Möller ice streams, West Antarctica, and comparison with Siple Coast ice streams [PDF]
, 2007 Subglacial bed conditions exert a significant control on ice stream behavior and evolution, and can be characterized by determining bed roughness from FFT analysis of radar-imaged basal reflectors. Here we assess bed roughness across Institute and Moller

Advanced Science, EarlyView.A conserved genomic region between two streptavidin genes in Streptomyces packages biosynthetic gene clusters for diverse biotin‐pathway antibiotics: acidomycin, stravidin, the new non‐proteinogenic amino acid ANDA, and the new BioA inhibitor α‐methyl‐KAPA.
