Flow cytometry, a widely used technique for single-cell analysis, often relies on fluorescent tags and lasers. While impedance-based flow cytometry avoids these drawbacks, they suffer from low sensitivity. In a recent study, researchers from Japan developed a low-cost adaptive platform that dynamically adjusts the microchannel height based on analyte size. Their approach significantly improved signal strength and quality, paving the way for accurate research findings which could result in clinical applications of impedance flow cytometry.

A practical approach to improving welfare outcomes in food animal production is the focus of the Center for Food Animal Wellbeing’s 11^th annual symposium, Oct. 2, at the Don Tyson Center for Agricultural Sciences in Fayetteville, featuring talks from veterinarians on topics from animal welfare audits to the metapneumovirus impact on turkeys.

NYU Abu Dhabi researchers reveal that a common frog color variation, green and brown morphs, has been preserved for millions of years, shaping evolution and biodiversity

A new Virginia Tech study published in PLOS One establishes a crucial baseline for understanding dog behavior on a large scale. 

The research, led by Courtney Sexton, a postdoctoral associate in the Virginia-Maryland College of Veterinary Medicine, and her colleague Yuhuan Li from the University of Washington, utilized four years of owner-reported data from over 47,000 dogs in the Dog Aging Project, a large-scale initiative involving over 40 institutions. 

Dogs reportedly became harder to train as the pandemic progressed, though this seemed to improve by the time it was ending, according to a study publishing September 10, 2025, in the open-access journal PLOS One by Courtney Sexton of Virginia Polytechnic Institute and State University, U.S., Yuhuan Li of the University of Washington, U.S., and colleagues.

Menopause-related hormone changes can cause hoarseness and vocal fatigue, often overlooked in women who rely on their voices professionally. Greater collaboration between gynecologists and voice specialists is needed, while emerging solutions — from AI voice biomarkers to hormone therapy and vocal fold injections — show promise for detection and treatment.
