Nautilus magazine also publishes excellent science journalism (https://nautil.us) with high-quality writing comparable to Quanta. In contrast with The Conversation, the contributors are typically professional journalists and writers—the writing quality is therefore often much higher and more literary than The Conversation's, though Conversation contributors have relevant specialist knowledge more often than Nautilus contributors.
Also, Lapham's Quarterly (https://www.laphamsquarterly.org) is perhaps comparable to Noema, as the magazine publishes essays and analyses of modern issues, often via making comparisons between current affairs and important parts of history. This looks similar to Noema's approach of analyzing current events from an academic perspective, from noticing references to academic publications in several essays featured on Noema's front page.
