Remembering War Photography’s Fallen Heroes [Memoriam]

Tim Hetherington and Chris Hondros were two of the most respected war journalists of the modern age, men who lived a soldier's life—and took a soldier's risks—to capture images from inside the heart of the battle. Both men's lives were taken in an RPG blast on April 20th in Libya. Since then, an outpouring of tributes from friends and collaborators have given shape the lives of the men who shaped our understanding of war. More »


Researchers construct RNA nanoparticles to safely deliver long-lasting therapy to cells

Nanotechnology researchers have known for years that RNA, the cousin of DNA, is a promising tool for nanotherapy, in which therapeutic agents can be delivered inside the body via nanoparticles. But the difficulties of producing long-lasting, therapeutic RNA that remains stable and non-toxic while entering targeted cells have posed challenges for their progress. Now, researchers detail successful methods of producing large RNA nanoparticles and testing their safety in the delivery of therapeutics to targeted cells.
