Report analyzes the present and future of North America's most important trade agreement‎

In 2020, the United States-Mexico-Canada Agreement (USMCA) replaced the North American Free Trade Agreement (NAFTA) as the primary trade framework for the three countries. The agreement is now being reviewed by the three countries. In a new report by the Brookings Institution, experts delved into what the agreement has meant for the three countries, and how the three states can ensure that the partnership can be successful going forward.

Promoting communication in English among students learning English as a foreign language‎

Language skills like reading, writing, listening, and speaking are essential for effective communication in English and are closely linked to educational and professional success both locally and internationally. In many non-English-speaking countries, students learn English as a foreign language (EFL) for their future endeavors, making it important to create classroom environments that support effective learning and communication.

Large mammal declines reshape nutrient flows in African savannas—with consequences for tadpoles‎

A new study led by researchers from the Museum für Naturkunde Berlin reveals how the loss of large mammals can ripple through ecosystems in unexpected ways, even affecting amphibian larvae living in temporary ponds. By examining changes in nutrient dynamics over more than two decades, the researchers show that declines in large herbivores are associated with a system-wide reduction in nitrogen isotope values in aquatic habitats, highlighting how disruptions in terrestrial wildlife populations can cascade across ecosystem boundaries.

Q&A: Expert discusses AI, automation drive autonomous science origin in scientific research‎

Rob Moore is a recognized leader in the development of autonomous science and self-driving laboratories at the Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL). A Tennessee native who spent five years as a U.S. Navy submarine officer, Moore joined ORNL in 2019 to perform research in the syntheses and characterization of quantum materials.

Well-placed poplar plantations can enhance forest connectivity for birds‎

A new study shows how fast-growing poplar plantations can improve functional connectivity for forest birds in fragmented agricultural landscapes, provided they are strategically located and species have moderate to high dispersal capacity. The findings suggest that managed forests may contribute not only to biomass supply, but also to biodiversity conservation in highly human-modified regions.

The hidden factor shaping dementia caregiving stress: Relationships‎

Caring for a spouse with dementia is arguably one of the most emotionally and physically demanding roles a person can take on, but new research from Rice University suggests the experience is not defined by the diagnosis alone. It is shaped by the relationship behind it. The study, published in Biopsychosocial Science and Medicine, examines how relationship dynamics influence the mental and physical health of people caring for spouses with Alzheimer's disease and related dementias.

Flowering in the city: The bumblebee connection‎

Why are flowers so different from one another? Much of the answer lies with pollinators: Their preferences and morphologies have helped generate an exceptional diversity of flowers in terms of shape, size, color and scent, forcing them to adapt so they can reproduce effectively.

Each protein in the epigenome produces a different pattern of gene expression, study finds‎

A new study finds the proteins responsible for controlling which genes are expressed in a genome do more than simply turn a gene on or off. Essentially, each type of protein that interacts with a gene produces different behaviors—a finding with ramifications for everything from biomedical therapeutics to biological computing. A paper on the study, "Epigenome Regulators Imbue a Single Eukaryotic Promoter with Diverse Gene Expression Dynamics," is published in the journal iScience.

Millimeter-scale resolution in fiber-optic sensing: Single-ended technique advances infrastructure monitoring‎

Distributed fiber-optic sensors are widely used to monitor temperature and strain in infrastructure, but their spatial resolution has long been limited. In a new study, researchers from Shibaura Institute of Technology and Yokohama National University, Japan, have demonstrated that operating near a previously avoided frequency regime and suppressing signal distortions allows reflection-based sensing to achieve a world-record spatial resolution of 6 mm among single-end-access configurations. This enables precise monitoring of temperature and strain in infrastructure.
