How AI could lead to a better understanding of the brain
Can a computer be programmed to simulate a brain? It’s a question mathematicians, theoreticians and experimentalists have long been asking — whether spurred by a desire to create artificial intelligence (AI) or by the idea that a complex system such as the brain can be understood only when mathematics or a computer can reproduce its…

Nature retracts controversial superconductivity paper by embattled physicist
Physicist Ranga Dias is under investigation by his institution, the University of Rochester in New York.Credit: Lauren Petracca/New York Times/Redux/eyevine Nature has retracted a controversial paper1 claiming the discovery of a superconductor — a material that carries electrical currents with zero resistance — capable of operating at room temperature and relatively low pressure. Why a…

Ligand recognition and G protein coupling of trace amine receptor TAAR1
Abstract Trace amine-associated receptors (TAARs), a group of biogenic amine receptors, play pivotal roles in neurological and metabolic homeostasis1. They recognize diverse endogenous trace amines (ETAs) and subsequently activate a range of G protein subtype signaling pathways2,3. Notably, TAAR1 has emerged as a promising therapeutic target for treating psychiatric disorders4,5. However, the molecular mechanisms underlying…

Recognition of methamphetamine and other amines by trace amine receptor TAAR1
Abstract Trace amine-associated receptor 1 (TAAR1), the founding member of a nine-member family of trace amine receptors, is responsible for recognizing a range of biogenic amines in the brain, including the endogenous β-phenylethylamine (β-PEA)1 as well as methamphetamine (METH)2, an abused substance that has posed a severe threat to human health and society3. Given its…

Spotlight on air pollution in Africa
Africa’s worsening air pollution has received too little attention. We argue that actions are needed in energy transition management, transport emission regulation and waste management to protect Africa’s air quality. Download PDF Africa is experiencing some of the worst air pollution in the world and air quality has deteriorating rapidly over the past 50 years1…

Real-time monitoring of the reaction of KRAS G12C mutant specific covalent inhibitor by in vitro and in-cell NMR spectroscopy
Abstract KRAS mutations are major drivers of various cancers. Recently, allele-specific inhibitors of the KRAS G12C mutant were developed that covalently modify the thiol of Cys12, thereby trapping KRAS in an inactive GDP-bound state. To study the mechanism of action of the covalent inhibitors in both in vitro and intracellular environments, we used real-time NMR…

Community speaks up for science in the UK culture wars
Last month I coordinated an open letter to the UK prime minister and the UK secretary of state for science, innovation and technology (go.nature.com/47exuxk), which directly challenges their vow to banish “the slow creep of wokeism” and “political correctness” from science (go.nature.com/3twjxdx). Competing Interests The author declares no competing interests.
