New research on colorectal cancer incidence, screening among younger US adults

JAMA Network
Peer-Reviewed Publication

About The Studies: This issue of JAMA includes three studies on colorectal cancer incidence and screening among younger U.S. adults.

Residential care increases social participation but gaps remain

University of Colorado Anschutz Medical Campus
Peer-Reviewed Publication

A new study from the University of Colorado Anschutz Medical Campus finds that older adults become more socially active after moving into long-term care communities like nursing homes or assisted living facilities but we might not all benefit equally.

Oral semaglutide in an East Asian population with overweight or obesity, with or without type 2 diabetes

JAMA Network
Peer-Reviewed Publication

In this randomized clinical trial, among East Asian adults with overweight or obesity, with or without type 2 diabetes, oral semaglutide, 50 mg, led to a superior and clinically meaningful reduction in body weight compared with placebo, with a safety profile consistent with the glucagon-like peptide-1 receptor agonist class.

Glucagon-like peptide-1 receptor agonist eligibility among US adolescents and young adults

JAMA Network
Peer-Reviewed Publication

This study found that nearly 17 million adolescents and young adults were eligible for glucagon-like peptide-1 receptor agonist (GLP-1RA) therapy. One in 5 young adults eligible for GLP-1RAs were uninsured and one-third denied having a routine place for health care—a barrier to identifying, treating, and preventing cardio-kidney-metabolic diseases.

Researchers discover cause of sea star wasting disease

Hakai Institute
Peer-Reviewed Publication

Today in Nature Ecology & Evolution, a group of researchers reveals the cause of sea star wasting disease (SSWD). This discovery comes more than a decade after the start of the marine epidemic that has killed billions of sea stars—representing over 20 different species from Alaska to Mexico. SSWD is considered the largest marine epidemic ever documented in the wild.

Nature livestreams build real human ties

University of Texas at Arlington
Peer-Reviewed Publication

New research from The University of Texas at Arlington reveals that nature-focused livestreams do more than connect viewers to the natural world; they also foster meaningful human connections.

Coulomb attraction driven spontaneous molecule-hotspot pairing

Opto-Electronic Journals Group
Peer-Reviewed Publication

Raman spectroscopy is based on the principle of inelastic light scattering, enabling precise analysis and identification of materials by detecting spectral characteristics of low-frequency modes such as vibrations and rotations in molecules, solids, and two-dimensional materials. This technology offers advantages including label-free detection, rich information content, and non-destructive analysis, demonstrating broad application prospects in chemistry, biology, medicine, environmental science, and other fields. However, as a higher-order light-matter interaction process, Raman scattering has an inherently tiny scattering cross-section, with signal intensity far lower than fluorescence and Rayleigh scattering.
