Fluid-absent metamorphism in the Adirondacks [PDF]

open access: yes
Results on late Proterozoic metamorphism of granulite in the Adirondacks are presented. There more than 20,000 sq km of rock are at granulite facies. Low water fugacites are implied by orthopyroxene bearing assemblages and by stability of k'spar-plag ...

Freeze‐tolerant frogs accumulate cryoprotectants using photoperiod: A potential ecological trap

open access: yesJournal of Animal Ecology, EarlyView.
Climate change is disrupting the reliability of photoperiod as a cue signalling seasonal changes in temperature. We show that gray treefrogs under a late‐season photoperiod accumulated large reserves of ‘antifreeze’ and exhibited greater cold tolerance.

Origin and significance of 'dispersed facies' basal ice: Svínafellsjökull, Iceland [PDF]

open access: yes, 2010
Dispersed facies basal ice - massive (i.e. structureless) ice with dispersed debris aggregates - is present at the margins of many glaciers and, as a product of internal glacial processes, has the potential to provide important information about the ...

An mTOR‐Tfeb‐Fabp7a Axis Ameliorates bag3 Cardiomyopathy via Decelerating Cardiac Aging

open access: yesAging Cell, EarlyView.
This study uncovered accelerated cardiac senescence as a key pathological event in bag3 cardiomyopathy, and reveals that manipulating the mTOR‐Tfeb‐Fabp7a axis can mitigate this pathology and confer cardioprotective effects. ABSTRACT While BAG3 has been identified as a causative gene for dilated cardiomyopathy, the major pathological events in BAG3 ...

Evolution of research on global amphibian declines

open access: yesConservation Biology, EarlyView.
Abstract In the late 1980s, the scientific community became aware of severe, enigmatic amphibian population declines. These declines triggered a wave of research focused on quantifying their extent and identifying key drivers. We used text‐analysis techniques, including topic modeling and geoparsing, to examine the evolution of research focused on ...

A CRISPR‐Cas9‐based system for the dose‐dependent study of DNA double‐strand break sensing and repair

open access: yesThe FEBS Journal, EarlyView.
Using CRISPR‐Cas9, we engineered a genetic system allowing the dose‐dependent induction of a controllable number of DNA double‐strand breaks in Saccharomyces cerevisiae. The tool was used to study the kinetics of DNA break sensing and repair, including the spatial distribution of Tel1ATM kinase, which initiates the DNA damage response.

US graphite sourcing for electric vehicle battery applications

open access: yesJournal of Industrial Ecology, EarlyView.
Abstract Graphite is a key material in electric vehicle batteries. Currently, China dominates global graphite production, and US sourcing of graphite could mitigate geopolitical supply‐chain risk. We explore the feasibility of domestic natural graphite sourcing in North America by characterizing current deposits and modeling the expected demand from ...

Dominance of grain size impacts on seasonal snow albedo at deforested sites in New Hampshire [PDF]

open access: yes, 2017
Snow cover serves as a major control on the surface energy budget in temperate regions due to its high reflectivity compared to underlying surfaces.

Confronting Episodic vs. Continuous Heat Sources in Long‐Lived Hot Orogens: Insights From Petrochronological Studies in the Nova Venecia Complex, Araçuaí Orogen (SE Brazil)

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT Orogenic belts that sustain elevated temperatures at intermediate crustal depths for tens of millions of years are known as hot orogens. The evolution of these hot orogens is largely influenced by thermal maturation, primarily driven by the distribution of heat‐producing elements (HPEs), such as K, Th and U in the overthickened crust.

Thermal structure and exhumation history of the Lesser Himalaya in central Nepal [PDF]

open access: yes, 2004
The Lesser Himalaya (LH) consists of metasedimentary rocks that have been scrapped off from the underthrusting Indian crust and accreted to the mountain range over the last ~20 Myr. It now forms a significant fraction of the Himalayan collisional orogen.
