Some interpretations of quantum mechanics propose that our entire universe is described by a single universal wave function that is constantly dividing and multiplying, producing a new reality for every possible quantum interaction. That’s a pretty bold statement. So how do you get there? One of the earliest realizations in the history of quantum mechanics …

A digital illustration inspired by the methane-eating Archaea and the Borg who assimilate them. Credit: Jenny Nuss/Berkeley Lab A newly discovered type of transfer DNA DNA, or deoxyribonucleic acid, is a molecule made up of two long strands of nucleotides that wrap around each other to form a double helix. It is the hereditary material …
