Inventing a Tiny Pacemaker with John Rogers, PhD

A Northwestern Medicine clinical trial led by Rod Passman, MD, could improve the way we care for millions of people with atrial fibrillation, but it is facing an unexpected challenge. There has been a pause in federal funding to Northwestern University that could impact this study's progress. While the trial has not been ordered to stop, all National Institutes of Health funding to Northwestern University has been frozen, raising questions about how long this potential life-saving work can go on without a resolution.  

Each year, more than 800,000 Americans suffer a heart attack and many of those who survive are left with irreversible scarring and the slow progression towards heart failure. In this episode, Edward Thorp, PhD, explains how his team is exploring immune cells that influence the heart’s ability to heal after such injuries. In Thorp’s lab, they are uncovering fundamental molecular mechanisms by which the immune system regulates wound repair, reduces inflammation and regenerates tissue. 

New evidence shows that a one-time intervention can lead to lasting improvement in the lives of young people struggling with mental health problems. In this episode, Jessica Schleider, PhD, associate professor of Medical Social Sciences, explains how she is using this approach to scale single-session interventions (SSIs) to reach more people in need of mental health services.

In this episode, Minjee Kim, MD, shares results of recent studies she has conducted to better understand the role of inadequate sleep on long-term metabolic health in pregnant women and middle-aged adults. She also discusses a new AI-based intervention that could bring a better night of sleep to those who need it. 

In this episode, Rodrigo Braga, PhD, explains recent advances in his Human Cognitive Neuroscience Lab, using precision functional MRI technology, that is helping us better understand how the brain is working. He details recent findings published in Science Advances that provide new understanding of how the brain works during and after social interactions, which could lead to new ways to treat anxiety and depression. 

What could be the world's smallest pacemaker was recently developed at Northwestern University and details of the device were published in the journal Nature. This incredible innovation, about the size of a grain of rice, from the lab of John Rogers, PhD, is designed to be an alternative to bulky, wired temporary pacemakers. In this episode, Rogers discusses how Northwestern engineers and Feinberg investigators came together to develop this innovative solution to meet a need for patients. 

A Northwestern Medicine study published in Nature Medicine, used a new technique called spatial transcriptomics to examine the brain’s response to Alzheimer's therapies, revealing new molecular targets that could enhance the effectiveness of current therapies and not just slow the disease, but potentially improve patient outcomes. David Gate, PhD, assistant professor of Neurology in the Ken and Ruth Davee Department of Neurology and director of the Abrams Research Center on Neurogenomics, led this research. 

A new $11.7 million award from the National Institute of Mental Health aims to help Northwestern Medicine investigators move the dial on the youth mental health crisis by targeting early warning signs of mental health risk in toddlers, rather than waiting until diagnosable and severe conditions are present later in childhood. In this episode, Lauren Wakschlag, PhD, who is co-leading this grant, explains how the team will implement evidence-based developmental decision tools to determine “when to worry” about young children's mental health.

Women are living longer, healthier lives, but ovarian aging still impacts fertility and hormone production as it always has. In this episode, Francesca Duncan, PhD, discusses novel research into maintaining ovarian function, longer. This work could someday help prevent or slow down age-related changes to the ovaries, offering hope for better health as women age.

Scientists from Northwestern Medicine, the Broad Institute of MIT and Harvard have uncovered the first rare genetic disorder linked to a long non-coding RNA gene. In this episode, Gemma Carvill, PhD, explains how this discovery, published in The New England Journal of Medicine, came to be and the critical roles non-coding regions of the genome may have in human health.
