The enzyme tRNA-guanine transglycosylase (TGT) chemically modifies transfer RNA (tRNA) and plays a key role in how disease-causing bacteria control the production of proteins needed to cause infection. E. coli TGT is nearly identical to the one found in Shigella, which causes the
Many people drive more carefully for a while after receiving a traffic fine. But do large corporations, such as airlines, also change their behavior when they face financial penalties? We examine this question by studying penalties imposed in the United States for lengthy tarmac
Researchers at the University of Twente have developed an optical method that follows the shape changes of a single protein in liquid without attaching anything to it. It reads the protein's structure from its own molecular vibrations, free from the labels or tags that other tech
A research team led by UCLA and the University of Rochester has demonstrated a promising evolution of an imaging system designed to capture details within "complex media," which scatter light, from depicting structures inside body tissue to seeing obstacles through heavy fog. The
Semiconductor surfaces can generally be studied only with considerable experimental effort, for example, in an ultrahigh vacuum. To more easily gain new insights into their properties and the possibilities for targeted modification, scientists at Heidelberg University have develo
Social networks, intended to bring people together, can actually increase polarization, new research finds, because while the links in the network may be plentiful, they're probably weak. A research team including Cornell sociologist Michael Macy has found that while the growing
Controlling how oxygen reacts is important for improving technologies such as batteries, fuel cells and environmentally sustainable chemical processes. A research team led by professor Seung Jun Hwang from KAIST's Department of Chemistry has developed a molecular system capable o
Nature, Published online: 22 July 2026; doi:10.1038/d41586-026-02302-0Some researchers think the current eradication strategy is outdated. Plus, goats hurt their brains when they butt heads and what scientist will never hand over to AI.
