The Republican Party Is Now in Its End Stages
We are living in a time of bad metaphors. Everything is fascism, or socialism; Hitler's Germany , or Stalin's Soviet Union. Republicans, especially, want their followers to believe that America is on the verge of a dramatic time, a moment of great conflict such as 1968—or perhaps, even worse, 1860. (The drama is the point, of course. No one ever says, "We're living through 1955.") Ironically, the

Transfer RNAs (tRNAs) deliver specific amino acids to ribosomes during translation of messenger RNA into proteins. The abundance of tRNAs can therefore have a profound impact on cell physiology, but measuring the amount of each tRNA in cells has been limited by technical challenges. Researchers have now overcome these limitations with mim-tRNAseq, a method that can be used to quantify tRNAs in any
