Amount of information in visible universe quantified
 
Researchers have long suspected a connection between information and the physical universe, with various paradoxes and thought experiments used to explore how or why information could be encoded in physical matter. The digital age propelled this field of study, suggesting that solving these research questions could have tangible applications across multiple branches of physics and computing.

Not too many bugs are more destructive than the Lycorma delicatula , better known as the spotted lanternfly. Some experts say that when you see one, you should report it, then smash it. The invasive pest native to Asia first arrived in the United States seven years ago. It's a threat to trees, plants, crops, orchards, vineyards, and even jobs. And as if that's not bad enough, it excretes a gross
