Performance of a glider‐mounted multifrequency echosounder for measuring the vertical distribution and abundance of large pelagic copepods

Limnology and Oceanography: Methods, EarlyView.
Abstract The difficulty of sampling zooplankton communities in situ has driven advancements in autonomous, remote sensing technology. The goal of this paper was to perform a gear comparison study testing the performance of one such piece of technology—a glider‐mounted four‐frequency echosounder—against traditional shipboard methods of measuring ...

Hydrogels Incorporating Donor–Acceptor Stenhouse Adducts as a Platform for Photoinduced, On‐Off Switchable Release of Small Molecule Cargos

Macromolecular Rapid Communications, EarlyView.
Donor–acceptor Stenhouse aDdducts (DASAs) are known for their photoinduced tautomerization, which, when conjugated to block copolymers, can self‐assemble into tuneable polymersomes. These DASA‐polymersomes are being investigated for light‐controlled cargo release in biomedical applications.

Analysis of the Matrix Metalloproteinases Family Profile in Gastric Cancer Suggests Key Matrix Metalloproteinases for Tumor Development and Their Clinical Impact

Molecular Carcinogenesis, EarlyView.
ABSTRACT Gastric cancer (GC) is the fifth most common type worldwide, representing a public health problem. Among the genes related to this tumorigenesis, the family of matrix metalloproteinases (MMPs), essential regulators of the extracellular matrix (ECM), stand out for their involvement in the development and progression of GC.

Whole‐Genome Bisulfite Sequencing Identifies Blood‐Based DNA Methylation Biomarker for Hepatocellular Carcinoma

Molecular Carcinogenesis, EarlyView.
ABSTRACT Functional DNA methylation abnormalities are a hallmark of human cancers and may be a promising biomarker for their early diagnosis. Moreover, the largest methylation differences can improve the sensitivity of noninvasive diagnoses of solid tumors.

Forbs in Viking lands: the effect of disturbing dominant graminoids on recruitment in tundra grasslands

Oikos, EarlyView.
Grasslands, by definition, are dominated by graminoids. Nevertheless, forbs also make up a substantial part of vascular plant diversity in grasslands and are important resources of mammalian herbivores. However, forb recruitment is constrained by successful dominant graminoids, limiting access to safe sites for germination.

Field fluorometer and injection device for gauging streams with fast variations

Revista Águas Subterrâneas, 2013
When it is desired to measure the temporal evolution of the flow of a river in torrential, kinematic methods (reel, electromagnetic current meter) are not appropriate, because of turbulent flow types.

Plasticity in plant hydraulic traits: An evaluation of a common‐taxa experiment across a climatic gradient in the Western U.S.

PLANTS, PEOPLE, PLANET, EarlyView.
Due to climate change, plants are experiencing both prolonged drought events and increasingly variable water availability, prompting the need for better understanding of potential impacts on plant performance, as well as the identification of low‐water‐use plants.

Made in the shade: Leaf responses of native wildflowers to single‐axis photovoltaic solar energy

PLANTS, PEOPLE, PLANET, EarlyView.
As solar energy expands globally, balancing renewable power generation with biodiversity and ecosystem health has become an urgent challenge. This study investigated how native wildflowers respond at leaf level to the unique microclimates created by rotating solar panels in California's Central Valley.
