This September for Healthy Aging® Month, JMIR Aging is bringing peer-reviewed science off the page and into daily life. We are spotlighting four articles and their lead authors in a dedicated video series that illustrates the direct connection between academic research and real-world impact. Each feature demonstrates how evidence-based digital health solutions are moving beyond theoretical design to actively empower older adults, caregivers, and technology developers, showing how digital tools can foster independence, purpose, and vitality in everyday living. In our first video feature for the series, Anna Whittaker, PhD from the University of Stirling shares key insights from her research published in JMIR Aging.

African American and Black women report the lowest physical activity levels across demographic groups in the United States, driving elevated rates of preventable cardiometabolic diseases. While researchers increasingly turn to mixed methods to examine how social, cultural, and environmental factors shape exercise behaviors, how effectively are these quantitative and qualitative insights being combined?

Heart rate variability (HRV), the fluctuation in time intervals between consecutive heartbeats, has emerged as a key noninvasive indicator of stress, recovery, and overall cardiovascular health. With smartphone cameras and wearable sensors expanding remote monitoring capabilities, consumer access to HRV tracking has skyrocketed.

In low-resource settings, access to timely emergency trauma care is often a matter of life and death. In Uganda, traffic law enforcement officers and medical trainees frequently serve as the initial first responders and frontline caregivers for road traffic injuries, particularly those involving motorcycles.

As artificial intelligence rapidly transforms clinical workflows, medical educators face a unique dilemma: How do we prepare trainees for an AI-driven future without undermining their core diagnostic skills?  A recent piece from the Yale School of Medicine caught our eye because it directly explores this double-edged sword. Written by Serena Crawford, Associate Communications Director at Yale School of Medicine, the Q&A highlights the pioneering work of Jaideep Talwalkar, MD, Associate Dean for Educational Technology and Innovation, as he examines how ambient AI scribes impact medical students.

Japan is the world's most rapidly aging society, with nearly 30% of its population aged 65 or older. Yet despite a 90% smartphone penetration rate, only 21.6% of Japanese adults regularly use mobile health (mHealth) apps.

Artificial intelligence is rapidly shifting from experimental code to point-of-care medical decision-making. As machine learning models gain autonomy in diagnosing diseases and tailoring treatments, ensuring true patient autonomy through informed consent has become a vital ethical challenge.

Parkinson disease (PD) is predominantly recognized for its motor symptoms, yet covert cognitive decline affects many patients long before dementia occurs. Traditional in-person cognitive testing presents substantial barriers: severe mobility impairments make traveling to clinics difficult, expert evaluations suffer from long waitlists, and screening tools like the Montreal Cognitive Assessment (MoCA) rely heavily on fine motor tasks like drawing, which can confound cognitive scores.

Virtual care expanded rapidly during the COVID-19 pandemic, but understanding which cancer patients use virtual oncology services, and how it connects to unplanned emergency department (ED) visits, remains critical for equitable care.

Every June, the scholarly publishing ecosystem undergoes a familiar ritual. Inboxes and industry feeds flood with identical, celebratory corporate press releases as Clarivate drops the latest Journal Citation Reports (JCR). But for publishing executives navigating a market defined by massive commercial consolidation, the real value of these metrics lies beneath the surface. The true strategic question isn't "Did our scores go up?" but rather, "What do these metrics tell us about the structural shift in where researchers want to publish?"
