Investigating Subglacial Water‐Filled Cavities by Spectral Analysis of Ambient Seismic Noise: Results on the Polythermal Tête‐Rousse Glacier (Mont Blanc, France)

open access: yesGeophysical Research Letters
Polythermal glaciers can trap considerable volumes of liquid water with the potential to generate devastating outburst floods. This study aims to identify water‐filled subglacial reservoirs from ambient seismic noise collected by moderate‐cost surveys ...

DEM Generation from Multi Satellite PlanetScope Imagery

open access: yesRemote Sensing, 2018
Planet Labs have recently launched a large constellation of small satellites (3U cubesats) capable of imaging the whole Earth landmass everyday. These small satellites capture multiple images of an area on consecutive days or sometimes on the same day ...

Stress‐Induced Melting Controlled Failure Mechanisms of Methane Hydrate

open access: yesAdvanced Science, EarlyView.
We study methane hydrate via nanoindentation and nuclear magnetic resonance (NMR), finding its regional melting and mechanical properties, challenging existing views on hydrogen‐bonded crystals. Abstract Methane hydrate, a kind of nonstoichiometric crystalline, attracted worldwide attentions as a promising substitute energy. Its Dissociation is thought

Influence of Glacial Meltwater on Summer Biogeochemical Cycles in Scoresby Sund, East Greenland

open access: yesFrontiers in Marine Science, 2019
Greenland fjords receive considerable amounts of glacial meltwater discharge from the Greenland Ice Sheet due to present climate warming. This impacts the hydrography, via freshening of the fjord waters, and biological processes due to altered nutrient ...

Oral Celastrol Nanomedicine Targeting Intestinal Antigen‐Presenting Cells to Effectively Mitigate Autoimmune Uveitis via Gut‐Retina Axis

open access: yesAdvanced Science, EarlyView.
Oral nanoCEL exhibits effective intestinal targeting of antigen‐presenting cells and restores the Th17/Treg balance in lymph nodes and spleen, ultimately protecting the blood‐retinal barrier by inhibiting peripheral immune cell infiltration and suppressing retinal glial cell activation.

Mid-Miocene cooling and the extinction of tundra in continental Antarctica [PDF]

open access: yes, 2008
A major obstacle in understanding the evolution of Cenozoic climate has been the lack of well dated terrestrial evidence from high-latitude, glaciated regions.

Natural Variations of ZmRLR1 Mediate the Root Lodging Resistance of Maize by Regulating Root Ascorbate and Auxin Homeostasis

open access: yesAdvanced Science, EarlyView.
Root lodging severely limits crop yield and quality. We reveal that ZmRLR1, a plasma membrane b‐type cytochrome, regulates lodging resistance in maize through dual roles: modulating intracellular redox balance and functioning as a novel component of clathrin‐mediated endocytosis to influence auxin homeostasis. Moreover, natural variations in the ZmRLR1

Asynchronous glacier dynamics during the Antarctic Cold Reversal in central Patagonia [PDF]

open access: yes, 2018
We present 14 new 10Be cosmogenic nuclide exposure ages quantifying asynchronous readvances during the Antarctic Cold Reversal from glaciers in the Baker Valley region of central Patagonia.

Glacier size changes in Kronotsky Peninsula and Alney-Chashakondzha Massif, Kamchatka Peninsula in the second half of XX century and the beginning of XXI century

open access: yesЛëд и снег, 2015
As it is known from recent investigations 448 glaciers are situated on the Kamchatka Peninsula, their total area are about 905 km2 [8]. More than 80% of them are glaciers of the Sredinny Range and the Klyuchevskaya group that is explained by large ...

3D‐Printed Architected Anisotropic Channels for Ultrafast Solar‐Driven Interfacial Evaporation via Localized Thermal Management and Water Layer Structuring

open access: yesAdvanced Science, EarlyView.
A 3D‐printed anisotropic channel evaporator integrates directional geometry with aligned titanium oxide, boron nitride, and chitosan networks to coordinate photon absorption, heat localization, and water transport. Phonon‐guided thermal pathways and interfacial water structuring enable ultrahigh evaporation rates and long‐term salt‐resistant solar ...
