Snapshots of Motion: A Novel Structural Intermediate Reveals Conserved Dynamics in Archaeal DNA Ligases

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 6, Page 1245-1258, June 2026.
ABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.

Strategic Roadmap for Addressing Microplastic Pollution in the Global South: Bridging Monitoring Gaps, Harmonizing Methods, and Building Analytical Capacity

Environmental Quality Management, Volume 35, Issue 4, Summer 2026.
ABSTRACT Microplastic (MP) pollution represents a growing environmental challenge, especially in tropical and subtropical coastal regions of the Global South, where methodological fragmentation, funding discontinuity, and dependence on external analytical infrastructure limit the production of comparable data and the formulation of evidence‐based ...

Political Cycles, Electricity Policy, and Mexico's Economy

Latin American Policy, Volume 17, Issue 2, June 2026.
ABSTRACT Electricity reform in Mexico should stimulate economic growth, improve energy efficiency, and reduce greenhouse gas emissions. This article evaluates the successes and failures of reform and draws lessons across political cycles by analyzing changes in political dynamics—often tied to policy reversals—and the legal framework during the pro ...

Da Vinci's mischief: xylem conduits in the stems of woody plants do not furcate

New Phytologist, Volume 250, Issue 5, Page 3001-3013, June 2026.
Summary The hydraulic architecture of plants is often modeled as a ‘furcating’ network, in which xylem conduits proliferate in number toward the stem apex, analogous to animal circulatory systems. Yet whether furcation actually occurs within woody stems remains untested, despite major implications for carbon costs and hydraulic efficiency.

The Lack of a COPII Cargo Receptor Erv14 Impacts Physiological Functions of the Vacuole in Saccharomyces cerevisiae

Traffic, Volume 27, Issue 2, June 2026.
Loss of the cargo receptor Erv14 in Saccharomyces cerevisiae results in sensitivity to calcium, zinc, neutral extracellular pH, and elevated temperature. Furthermore, cells deleted in the ERV14 exhibits vacuolar fragmentation, enlarged lipid droplets, and metabolic alterations. Ruiz Salas, J. L. (2026) https://BioRender.com/b65g523. ABSTRACT Erv14 is a

Evaluating TEMPO Formaldehyde Retrievals With Co‐Located Ground‐Based FTIR and Pandora Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Formaldehyde (HCHO) is an important proxy for volatile organic compounds and photochemical activity, with significant implications for air quality and atmospheric chemistry. The recently launched geostationary satellite instrument Tropospheric Emissions: Monitoring of Pollution (TEMPO) provides the first‐ever hourly observations of HCHO and ...

4D Printing of Multimaterial Flexible Magneto‐Active Polymers

Advanced Materials Technologies, Volume 11, Issue 9, 6 May 2026.
Magneto‐active polymers are 3D‐printed with tunable mechanical and magnetic properties using both superparamagnetic and hard ferromagnetic fillers. Nano‐CT imaging reveals the spatial distribution of particles within the matrix. Programmable magnetization patterns and soft, flexible architectures enable responsive actuation, offering exciting ...
