We have developed a rapid and sensitive single-well dual-parametric method introduced in linked RAS nucleotide exchange and RAS/RAF-RBD interaction assays. RAS mutations are frequent drivers of multiple different human cancers, but the development of therapeutic strategies has been challenging. Traditionally, efforts to disrupt the RAS function have focused on nucleotide exchange inhibitors, GTP-RAS interaction inhibitors, and activators increasing GTPase activity of mutant RAS proteins. As the amount of biological knowledge grows, ta

The extinct human relatives known as Neanderthals (Homo neanderthalensis) have long been described as brutish and dumb. This conception is often traced to paleontologist Marcellin Boule (1861-1942), who published a detailed analysis on a Neanderthal skeleton in the early twentieth century. The conventional historical narrative claims that Boule made an error in his analysis, causing the Neanderthals to be considered brutish. This essay challenges the narrative of "Boule's error," arguing instead that the brutish Neanderthal
