SEC Mediates m6A Deposition and Transcription Pause Release to Drive Cell Identity Transition

Advanced Science, EarlyView.
The SEC promotes cell identity transitions by facilitating transcription pause release at key identity‐associated genes, including Klf4 and Myc during iPSC reprogramming and Nes and Tubb3 during ESC‐to‐neuroectodermal differentiation. During early iPSC reprogramming, this function additionally involves cooperation with METTL3‐associated m6A regulation.

History of Alibek Glacier based on Earth remote sensing images, bioindication and cosmogenic isopotes (14С and 10Be)

Лëд и снег, 2015
In this article we present the reconstruction of fluctuations of Alibek valley glacier situated in the Teberda valley, Western Caucasus. The former positions of glacier of the past 120 years were reconstructed basing on the old photographs of 1904, 1921,

Engineering Spatially Localized Bioactive Microenvironments in Assembly Implants for Spatially Extended Bone Ingrowth

Advanced Science, EarlyView.
An assembly porous titanium/β‐TCP implant is developed to establish a spatially programmable osteogenic microenvironment for enhanced osseointegration. By decoupling mechanical support from bioactive ion release, localized ionic gradients generated from the β‐TCP module direct osteogenic activity and bone ingrowth toward the porous titanium framework ...

Temporal glacier velocity variations and their controlling factors in the Nathorstbreen glacier system, Svalbard

Egyptian Journal of Remote Sensing and Space Sciences
Temporal variations in glacier velocity are not only essential to understand glacier dynamics but also to predict glacier hazards. Therefore, in the current study, the continuous glacier velocities were estimated from 2014 to 2023 in the Nathorstbreen ...

Response of the flow dynamics of Bowdoin Glacier, northwestern Greenland, to basal lubrication and tidal forcing

Journal of Glaciology, 2019
We use the full-Stokes model Elmer/Ice to investigate the present dynamics of Bowdoin Glacier, a marine-terminating outlet glacier in northwestern Greenland.

Diurnal fluctuations in borehole water levels: configuration of the drainage system beneath Bench Glacier, Alaska, USA [PDF]

, 2008
Water levels were measured in boreholes spaced along the entire length of Bench Glacier, Alaska, USA, for a period in excess of 2 years. Instrumented boreholes were arranged as nine pairs along the center line of the glacier and an orthogonal grid of 16 ...

LigHTS: Biomimetic Hydrogel Photo‐Fabrication for Imaging‐Based Ultra‐High‐Throughput Screening

Advanced Science, EarlyView.
LigHTS removes a key bottleneck for ultra‐high‐throughput screening (UHTS) by enabling biomimetic hydrogel microenvironments to be manufactured directly in standard multiwell plates. A single, collimated UV exposure with formulation‐tuned light penetration patterns an entire plate with UHTS‐grade uniformity (<20% CV), producing structured GelMA films ...

Lateglacial to Early Holocene glacier fluctuations in the northern Valaisian Alps

Swiss Journal of Geosciences
The northern Valaisian Alps represents a glacially overprinted landscape, characterized by abundant glacial deposits and landforms. Well-preserved moraine systems, commonly found in the region, were deposited by glacier fluctuations after the Last ...

InSAR observations of ice elevation and velocity fluctuations at the Flade Isblink ice cap, eastern North Greenland [PDF]

, 2010
The 8500 km(2) Flade Isblink ice cap (FIIC) (81 degrees 15'N, 15 degrees 0'W) is the largest ice cap in Greenland. We use repeat-pass interferometric synthetic aperture radar (InSAR) techniques to investigate the form and flow of the FIIC.

Toward Sustainable Separation and Recovery of Critical Metals From Discarded Industrial Perovskite Solar Modules

Advanced Science, EarlyView.
An architecture‐guided recycling process enables selective metal recovery from end‐of‐life perovskite solar modules by exploiting interfacial accessibility and calcination‐induced phase transformation. The process achieves >99.8% Pb removal, >99.7% In recovery, and >96.1% Cu recovery, while selectively retaining Sn in leaching residue.
