Chromatin is a hybrid structure of DNA and protein that manages the complex problem of packaging 3 billion bases of DNA into a small bundle in the cell that is only a few micrometers in size. This is no small feat. The length of DNA from one cell would measure two meters in length if you stretched it out in front of you. This long

An international team of physicists behind several revolutionary warp drive concepts, including the first to require no exotic matter, says that recent unprecedented breakthroughs in physics and propulsion have launched the world powers into a Cold War-style, 21st-century space race to build the world’s first working warp drive.
