Working with “digital twins” of patients’ hearts, doctors improved cardiac ablation outcomes for patients with life-threatening arrythmias.

In the first clinical trials for cardiac digital twins technology, researchers at Johns Hopkins University created digital replicas of patients’ hearts, then tested procedures on those twins before performing them on the real thing. Working with digital twins resulted in faster and significantly more accurate procedures that reduced recurrences of arrythmias for patients, compared to traditional methods.

Researchers from the FAMU-FSU College of Engineering and the Florida Center for Advanced Aero-Propulsion, or FCAAP, are helping to solve a safety challenge in military aviation: the extreme noise generated by supersonic jets during takeoff and landing.

The research, published in the Journal of Fluid Mechanics, demonstrates a new model for understanding how supersonic jets of air collide with the ground or other structures to create a resonant feedback loop that produces extreme noise that can reach dangerous volume levels.

A new study tracking global progress on child mortality finds that the world will miss a key United Nations (UN) health target by at least five years at current rates, with the burden falling heavily on Sub-Saharan Africa. The findings were published this week in the open-access journal PLOS One by Min Liu of Peking University, Beijing, China, and colleagues.
