A full sized beating bioengineered human heart has been made with hearts recellularized with stem cells

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 their accomplishments – which include …

High power microwaves and laser weapons

Directed-energy (DE) weapons, including high-energy lasers (HEL), high-power microwaves (HPM) and related radiofrequency technologies, offer the prospect of cost-effective precision attack or enhanced point defense and can provide warfighters with flexible nonkinetic employment options. DE weapons have finally demonstrated sufficient technical maturity that they may be integrated into naval, air and ground force structure for …
