Online weight loss program is effective way to reach rural populations, study shows

University of Illinois College of Agricultural, Consumer and Environmental Sciences

People living in rural areas are at greater risk for obesity than the general population, and they often have limited access to healthy, affordable food, physical activity facilities, public transportation, and health care institutions. A research team at the University of Illinois Urbana-Champaign developed an online weight management program that provides personalized assistance from a registered dietitian. In a new study, they collaborated with Illinois Extension to test the program’s efficacy among residents of rural Illinois.

NTT Research and Harvard scientists optimize biohybrid ray development with machine learning

Harvard John A. Paulson School of Engineering and Applied Sciences
Peer-Reviewed Publication

The Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and NTT Research, Inc., a division of NTT, announced the publication of research showing an application of machine-learning directed optimization (ML-DO) that efficiently searches for high-performance design configurations in the context of biohybrid robots. Applying a machine learning approach, the researchers created mini biohybrid rays made of cardiomyocytes (heart muscle cells) and rubber with a wingspan of about 10 mm that are approximately two times more efficient at swimming than those recently developed under a conventional biomimetic approach.
