Despite their great distance from Earthbound politics, exoplanets were the topic of a joint hearing on May 9th of the House space and research subcommittees. The recent discovery of a trio of temperate super-Earths was the hearing’s impetus, but most of the discussion was devoted to future prospects—chiefly, how and when scientists might learn whether […]

Is there something special about humanity’s method of understanding the world around us? If there are other intelligent beings in the world, would their knowledge be important in the same way? David Deutsch‘s research suggests an affirmative answer to both questions. Deutsch is a physicist at the University of Oxford, a fellow of the Royal […]

One of the last things you’d expect to see at a physics conference is a physicist on stage, in a dapper hat, pounding out a few riffs of the blues on a keyboard. But that’s exactly what University of Illinois professor J. Murray Gibson did at the recent March meeting of the American Physical Society […]

Last week, we asked you to pick out human eyes from animal eyes that look similar. It was probably harder than you expected. This week’s eyeball challenge, again courtesy of some great photographs by Suren Manvelyan, might be even harder. Can you tell which very inhuman-looking eyes (bigger images below) belong to which animals?  Here’s […]

Any self-respecting pet owner will confidently claim that their dog or cat (or rabbit, or gerbil) seems sentient, exhibiting a distinct temperament and emotional responses. I know my many beloved pets over the years could feel pain, and fear, as well as love and trust. But are our pets truly conscious creatures? Or are we […]

You are standing on a sandy plain lit only by the harsh, cold light of a blue-white spark flashing overhead in steady metronomic bursts. The pinprick of light almost seems like a distant star, but each flash raises a disturbing tingling sensation within you, suggesting the stroboscopic light source is somehow nearby, and must be […]

In each issue of Nautilus, we shine a spotlight on one “Ingenious” scientist whose work makes us reconsider our world and ourselves. The Ingenious for our first issue, “What Makes You So Special,” is Columbia University astrophysicist Caleb Scharf, who contributed an essay about our place in the universe and talked about his life and […]

When an enormous four-finned fish surfaced in a South African fisherman’s catch in 1938, scientists were fascinated by its resemblance to fossilized creatures that had died out millions of years ago. The fish, called a coelacanth, turned out to be the first descendant of those organisms ever spotted by humans. The two living species identified […]

People place incredible importance on their eyes. They’re arguably our default tool for perceiving the world, and one of the primary ways we remember and describe one another. Your eye color is on your birth certificate, driver’s license, and online dating profile. Those who make eye contact are considered more competent, friendlier, and more professional. Online […]

Human nature is one of those aspects of the world that can seem inexplicable, too varied and complicated to be pinned down by overarching explanations. On the one hand our species includes people like Garrett O’Hanlon, who was standing on a Manhattan subway platform one recent night when someone passed out onto the tracks right […]
