To have the greatest impact on human health, biomedical research findings and evidence-based practices need to be implemented into routine healthcare. What is implementation science, and how can we ensure research successfully makes an impact? Rinad Beidas, PhD, and Sara Becker, PhD, discuss the field and its future as a research priority at Northwestern University Feinberg School of Medicine.

There’s been an uptick in childhood food allergies in recent years, and new evidence from Northwestern shows they’re also becoming more common in adults. Many of the reactions to these allergies are life-threatening. Why is this increase happening, and how can we keep people affected by food allergy safe? Ruchi Gupta, MD, MPH, is trying to answer those questions. This a rewind episode that originally was published in 2019.

A Northwestern Medicine course called Cooking Up Health is giving medical students, trainees and health professionals the opportunity to learn culinary medicine and food-as-medicine science concepts. Melinda Ring, MD, created the course and explains how it can improve the health of patients and train more nutrition-aware physicians.  

Understanding how genes function is a vital part of understanding how to better treat cancer. Research led by Mazhar Adli, PhD, is grounded in the development of a systematic approach to identify the function of each gene in the human body. His team aims to discover novel therapeutic drug combinations to prevent cancer development and chemotherapy resistance. 

Bariatric surgery is proving to be an effective tool to help teenagers with severe obesity lose weight and reverse the progression of weight-related conditions, according to findings from the Teen Longitudinal Assessment of Bariatric Surgery study (Teen-LABS). Thomas Inge, MD, PhD, principal investigator of Teen-LABS, shares results of the study, which is the only multicenter National Institute of Health sponsored research on adolescent bariatric surgery. 

How are habits – both good and bad – formed in the brain, and what role do habits play in diseases of the brain? These are some of the questions neuroscientist, Talia Lerner, PhD, is investigating in her lab.
