New core competency framework enhances support for SNAP-ED policy and environmental change implementers

Elsevier
Peer-Reviewed Publication

A recent study in the Journal of Nutrition Education and Behavior, published by Elsevier, outlines a set of core competencies designed to support professionals implementing policy, systems, and environmental (PSE) change initiatives in the Supplemental Nutrition Assistance Program Education (SNAP-Ed). Developed through a participatory process with experienced practitioners, the framework addresses the unique demands of systems-level public health work.

New survey: Majority of U.S. women say their health care providers have not informed them of diet’s role in prevention of breast cancer

Physicians Committee for Responsible Medicine
Reports and Proceedings

Up slightly from 16% last year, only 19% of women say a health care provider has discussed with them nutrition’s role in breast cancer risk in a new Physicians Committee for Responsible Medicine/Morning Consult survey. However, fewer of those same women specifically mention diet this year when asked what steps they’re aware of that women can take to lower their chances of developing breast cancer.

How bad are micro- and nanoplastics for our health? It depends on their concentrations and how you measure them

University of Massachusetts Amherst
Peer-Reviewed Publication

Collecting and analyzing the amount of toxic micro- and nanoplastics (MNPs) in water is comparatively easy: fill a bucket from your source, evaporate the water and count and characterize the plastics that are left behind. But what if you want to know how many MNPs are in that apple you’re about to eat, the tree in your backyard, or even in your brain?

Neural navigation: FAU engineers, sensing institute map brain’s blood flow

Florida Atlantic University
Peer-Reviewed Publication

Not all blood vessels play equal roles in brain health. To uncover how the brain regulates its complex circulation, researchers built a detailed computer model of mouse brain vasculature. Focusing on transitional zone vessels—crucial links between arteries and capillaries—the model simulates how each segment adjusts like a tiny valve. It reveals how the brain stabilizes blood flow during pressure shifts or heightened activity, offering new insights into brain protection and potential breakthroughs in diagnosing stroke, Alzheimer’s, and traumatic brain injuries.
