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

open access: yesAdvanced 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.

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

open access: yesAdvanced 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 ...

Lake sediments uncover glacier change on the Kerguelen Islands during the past 1500 years

open access: yesFrontiers in Earth Science
Climate change is driving the rapid retreat of glaciers across the sub-Antarctic zone. Using continuous lake sediment-based records of past glacier changes, the recent trends can be evaluated in a long-term context.

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

open access: yesAdvanced 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 ...

Tracing glacier changes in Austria from the Little Ice Age to the present using a lidar-based high-resolution glacier inventory in Austria

open access: yes, 2015
. Glacier inventories provide the basis for further studies on mass balance and volume change, relevant for local hydrological issues as well as for global calculation of sea level rise.

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

open access: yesAdvanced 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.

Machine Learning Driven Glacier Thickness Estimation in Diverse Continental Glaciers Using Innovative Pixel Based Skeletonization Approach

open access: yesWater Resources Research
With the growing availability of global glacier thickness data sets, there is a need for fast and adaptable approach to assess how glacier thickness changes over time. This study demonstrates how machine learning (ML) models can be trained using existing

Testing hypotheses of the cause of peripheral thinning of the Greenland Ice Sheet: is land-terminating ice thinning at anomalously high rates? [PDF]

open access: yes, 2008
Recent observations have shown that the periphery of the Greenland ice sheet (GrIS) is thinning rapidly and that this thinning is greatest around marine-terminating outlet glaciers. Several theories have been proposed which provide a link between climate

Dramatic Enhancement and Integration of Properties in Pork Belly‐Inspired All‐Biomass Composite Films via Facile, Sustainable, and Controllable Design

open access: yesAdvanced Science, EarlyView.
A pork belly‐inspired all‐biomass composite film was constructed through layer‐by‐layer assembly of cellulose nanofibers (CNFs), gelatin, and graphitized carbon nanosheets (GCNs) via hydrogen bonding and π–π stacking interactions. The excellent mechanical properties, effective thermal management, and outstanding EMI shielding performance of the ...
