For new readers, this collection of “missing links” rounds up fascinating stuff I find around the internet, and appears every Saturday. It’s separated into Top Picks (the best stuff), Science/News/Writing (science writing), Heh/Wow/Huh (silliness, satire, photos, videos), and Journalism/Internet/Society (a miscellany of my other interests). If links are broken, let me know in the comments. Top picks “Restless genes” by David Dobbs, about the genetics and other factors behind the human urge to explore, is one of the best science stories of the year, let alone the week. It’s beautifully written without sacrificing nuance.
