Lack of Hydraulic Acclimation in Response to Multiple Droughts and Recovery
ABSTRACT Human‐caused climate change is expected to bring more frequent and extended droughts with shorter wet periods of relief in between for many regions of the world. Critical knowledge gaps remain around the extent to which tree species can acclimate physiologically to repeated droughts.

A cooperative mechanism between a phosphinito Ir complex and HFIP provides a low‐energy pathway for hydrogen activation. This allowed the development of a highly efficient catalytic system for the hydrogenation of ketones that operates under acidic conditions, enabling the reduction of substrates containing phenols and carboxylic acids with no added ...

Interpreting algorithmic information cues: User sensemaking of search autocomplete moderation
Abstract Autocomplete is a search feature that algorithmically generates information cues for any keywords entered in the search bar. While this feature makes the search process more efficient, it also frequently produces biased, misleading, offensive, or otherwise inappropriate suggestions.

This study compared GC‐MS/MS, EA‐IRMS, and LC‐MS/MS for detecting synthetic and manipulated urine samples in doping control and forensic analysis. EA‐IRMS proved particularly effective for identifying mixtures of synthetic and authentic urine, providing a reliable complement to established authenticity testing methods.

Effects of Biochar and Maize Roots on CO2 Emissions and Microbial Biomass C in Loess Soils
ABSTRACT Background Refractory substances such as biochar and labile substances such as dead fine and coarse roots play important roles in soil organic matter dynamics and have key ecological functions. However, interactions between these substances have only rarely been studied.

Food availability impacts oxygen isotope composition in freshwater snail shells
Abstract Freshwater mollusk shells serve as valuable archives for the reconstruction of past environmental conditions as they record water temperatures in their stable isotopic compositions during biomineralization. Yet, the impact of food availability on these isotopic records has never been fully explored.
