  • Science Fiction True
    Don’t believe everything you see on TV or the movies. Science fiction is just a guide to how our future might unfold. It can be misleading, as anyone who yearns for a flying car can tell you. And yet, sometimes fantasy becomes fact. Think of

  • Shocking Ideas
    Electricity is so 19th century. Most of the uses for it were established by the 1920s. So there’s nothing innovative left to do, right? That’s not the opinion of the Nobel committee that awarded its 2014 physics prize to scientists who invented the blue LED.

  • Living Computers
    It’s the most dramatic technical development of recent times: Teams of people working for decades to produce a slow-motion revolution we call computing. As these devices become increasingly powerful, we recall that a pioneer from the nineteenth century – Ada Lovelace, a mathematician and Lord

  • Surfeit of the Vitalest
    In the century and a half since Charles Darwin wrote his seminal On the Origin of the Species, our understanding of evolution has changed quite a bit. For one, we have not only identified the inheritance molecule DNA, but have determined its sequence in many

  • Skeptic Check: Are You Sure You’re Sure?
    Nuclear fission powers the Sun. Or is it fusion? At any rate, helium is burned in the process, of that you are certain. After all, you read that article on astronomy last week*. You know what you know. But you probably don’t know what you

  • Tale of the Distribution
    We all have at least some musical talent. But very few of us can play the piano like Vladimir Horowitz. His talent was rarefied, and at the tail end of the bell curve of musical ability – that tiny sliver of the distribution where you

  • Who’s Controlling Whom?
    A single ant isn’t very brainy. But a group of ants can do remarkable things. Biological swarm behavior is one model for the next generation of tiny robots. Of course, biology can get hijacked: a fungus can seize control of an ant’s brain, for example. So

  • What's the Difference?
    We make split second decisions about others – someone is male or female, black or white, us or them. But sometimes the degrees of separation are incredibly few. A mere handful of genes determine skin color, for example. Find out why race is almost non-existent

  • Land on the Run
    Hang on to your globe. One day it’ll be a collector’s item. The arrangement of continents you see today is not what it once was, nor what it will be tomorrow. Thank plate tectonics. Now evidence suggests that the crowding together of all major land

  • Moving Right Along
    You think your life is fast-paced, but have you ever seen a bacterium swim across your countertop? You’d be surprised how fast they can move. Find out why modeling the swirl of hurricanes takes a roomful of mathematicians and supercomputers, and how galaxies can move

  • Eye Spy
    Who’s watching you? Could be anyone, really. Social media sites, webcams, CCTV cameras and smartphones have made keeping tabs on you as easy as tapping “refresh” on a tablet. And who knows what your cell phone records are telling the NSA? Surveillance technology has privacy

  • Replace What Ails You
    Germs can make us sick, but we didn’t know about these puny pathogens prior to the end of the 19th century. Just the suggestion that a tiny bug could spread disease made eyes roll. Then came germ theory, sterilization, and antibiotics. It was a revolution

  • A Stellar Job
    The stars are out tonight. And they do more than just twinkle. These boiling balls of hot plasma can tell us something about other celestial phenomena. They betray the hiding places of black holes, for one. But they can also fool us. Find out why

  • What Do You Make Of It?
    You are surrounded by products. Most of them, factory-made. Yet there was a time when building things by hand was commonplace, and if something stopped working, well, you jumped into the garage and fixed it, rather than tossing it into the circular file. Participants at

  • Skeptic Check: Check the Skeptics
    One day, coffee is good for you; the next, it’s not. And it seems that everything you eat is linked to cancer, according to research. But scientific studies are not always accurate. Insufficient data, biased measurements, or a faulty analysis can trip them up. And
