Generation of Three-Dimensional Heart Organoids Researchers engineered three-dimensional functional heart organoids resembling the developing heart. By exposing mouse embryonic stem cells to two key proteins during heart development, the researchers were able to form heart organoids with structural, functional, and molecular similarities to the embryonic heart during development. This method could be used to study heart development and to ... RELATED TOPICS Heart Disease

Promising Computer Simulations for Stellarator Plasmas The turbulence code GENE (Gyrokinetic Electromagnetic Numerical Experiment), has proven to be very useful for the theoretical description of turbulence in the plasma of tokamak-type fusion devices. Extended for the more complex geometry of stellarator-type devices, computer simulations with GENE now indicate a new method to reduce plasma turbulence in stellarator plasmas. This could significantly ... RELATED TOPICS Computer Modeling

New Mathematical Tool Can Select the Best Sensors for the Job In the 2019 Boeing 737 Max crash, the recovered black box from the aftermath hinted that a failed pressure sensor may have caused the ill-fated aircraft to nose dive. This incident and others have fueled a larger debate on sensor selection, number and placement to prevent the reoccurrence of such tragedies. Researchers have now developed a comprehensive mathematical framework that can help ... RELATED TOPICS Detectors
