The man suspected of firing down into an outdoor music festival on the Las Vegas Strip on Sunday night, killing at least 59 people and injuring 527, managed to haul at least 23 firearms—plus ammunition, gun stands, scopes, and other accessories—into his hotel room on the 32nd floor of the Mandalay Bay.

Stem cells. Few research discoveries hold as much promise of single-handedly expanding medical treatment options as they do. Miraculously able to act as transformers either re-creating or morphing into a variety of cell types found within the organisms they originate from stem cells offer humanity hope for new, more effective therapies against a number of chronic and terminal diseases. And finding them is surprisingly easy.
