Fermions to bosons, bosons to fermions

University of Cincinnati theoretical physicists are about to report on a controversial discovery that they say contradicts the work of researchers over the decades. The discovery concerns the conventional approach toward bosonization-debosonization. For folks outside the physics lab and the whiteboard, this could affect calculations regarding the future of quantum ...

Functional heart muscle regenerated in decellularized human hearts

Massachusetts General Hospital (MGH) researchers have taken some initial steps toward the creation of bioengineered human hearts using donor hearts stripped of components that would generate an immune response and cardiac muscle cells generated from induced pluripotent stem cells (iPSCs), which could come from a potential recipient. The investigators described ...
