A team of researchers at Bar-Ilan University has found a way to use correlated photons to make sharper X-ray images. In their paper published in the journal Physical Review Letters, the group describes their process and suggest ...
About 70 percent of the human genome doesn't code for anything. When it's transcribed to RNA—the instructions our cells follow when they make proteins—most of the message doesn't contain any useful information. As West ...
