Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Ice surface change drives subglacial hydrologic reorganization and interior speedup in northwest Greenland

open access: yesJournal of Glaciology
Changes in ice surface elevation and slope influence subglacial water pressure and sliding velocity. Leveraging changes in elevation observed by the Ice, Cloud and land-Elevation satellite (ICESat) and ICESat-2 missions, we use coupled subglacial ...

A temperate former West Antarctic ice sheet suggested by an extensive zone of bed channels [PDF]

open access: yes, 2014
We present radio-echo sounding data and satellite imagery, revealing a series of ancient large sub-parallel subglacial channels preserved in the region between the Möller and Foundation Ice Streams, West Antarctica.

Identification and characterization of a gene conferring stress resistance in Escherichia coli and cyanobacteria

open access: yesFEBS Open Bio, EarlyView.
Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.

Terminus thinning drives recent acceleration of a Greenlandic lake-terminating outlet glacier

open access: yesJournal of Glaciology
Ice-contact proglacial lakes affect ice dynamics and the transition of glacier termini from land- to lake-terminating has been shown to cause ice flow acceleration.

Plasma EV Proteomics Identifies ECM Remodeling and Inflammatory Proteins LUM and C7 as Candidate Biomarkers in FSHD

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Facioscapulohumeral muscular dystrophy (FSHD) is one of the most debilitating and common muscular dystrophies. Despite its severity, no approved therapy exists for FSHD patients. However, several therapeutic candidates are currently under development, and some have recently entered clinical trials, marking the need for reliable ...

Impact of Hydrogen Incorporation on Electronic and Magnetic Structure of X2CrNi18‐9 Stainless Steel

open access: yesAdvanced Engineering Materials, EarlyView.
Hydrogen uptake in austenitic stainless steel alters both its electronic and magnetic structure. Seebeck measurements reveal hydrogen‐induced shifts in the electronic density of states, while neutron scattering uncovers nanoscale inhomogeneities that grow upon hydrogen incorporation, with the most pronounced effect observed in the PBF as‐built state ...

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Unravelling Shifting Speeds: Recent Surface Ice Velocity Fluctuations on Larsen Ice Shelf

open access: yes
Antarctic ice shelves, like Larsen C, are crucial for stabilizing inland glaciers and mitigating global sea level rise, but they are highly sensitive to atmospheric and oceanic changes. As the largest remaining section of the Larsen system, Larsen C is a key focus for monitoring due to its susceptibility to structural destabilization under climate ...

A physically based calving model applied to marine outlet glaciers and implications for the glacier dynamics [PDF]

open access: yes, 2010
We present results from numerical ice-flow models that include calving criteria based on penetration of surface and basal crevasses, which in turn is a function of longitudinal strain rates near the glacier front.
