Dealing with people who exhibit passive-aggressive behavior is easily one of the most challenging aspects of our social lives. Here’s what you need to know about this annoying personality quirk and how you can handle people who express their hostility in indirect and backhanded ways.

Do you think you know what a cornfield looks like? You don’t know what a cornfield looks like.

Teeth grinding is a problem that affects nearly one in ten individuals, yet many of us don’t even realize we’re doing it. And that’s a problem given just how harmful it can be to our health. Here’s how to find out if you grind your teeth when you sleep—and why it’s something you shouldn’t ignore.

This year marks the 75th anniversary of the Battle of Britain, the first time in history that one nation tried to defeat another using airstrikes. Here’s how the Nazis thought they could do it—and how agonizingly close they actually came to achieving victory.

Brave New World used to be one of the most terrifying stories about a false utopia. It gave us the concept of “test tube babies,” and its name became synonymous with technological progress run wild. But many of the things Aldous Huxley predicted are coming true, and it turns out they’re not so scary.

Traditional farming is taking a huge toll on the environment—a problem that’s set to worsen due to our ever-growing global population. Yet there are some high-tech solutions. Here’s what you need to know about the burgeoning practice of controlled-environment agriculture and how it’s set to change everything from the…

Unlike a certain companion animal that will go unnamed, dogs lose their minds when reunited with their owners. But it’s not immediately obvious why our canine companions should grant us such an over-the-top greeting—especially considering the power imbalance that exists between the two species. We spoke to the experts…

Pluto and Charon have captured our hearts and imaginations. But how did these adorably strange worlds form, and what consequences could that have on what we see now? Researcher Amy Barr Mlinar chatted with us about catastrophic collisions, subsurface oceans, and Pluto’s lack of craters.

“Space is big,” said Douglas Adams. “You just won’t believe how vastly, hugely, mind-boggingly big it is.” But why must this be so? And why does our Universe exhibit such tremendous scale, from the very tiny to the extremely large? Here are some possible answers.

The sensory chaos of battle has always posed a challenge to armies hoping to prepare for—and recover from—war. And while it’s clear to most people how sight and sound factor into a soldier’s experience and memory of battle, the smells of combat were, for most of history, largely ignored. But by the eve of the 20th…

Despite the weirdness of existence, most of us are able to get on with our lives and avoid debilitating feelings of despair, personal failure, and cosmic meaninglessness. But every once in a while we’re tugged out of our complacency and forced to re-evaluate our lives. Here’s what you need to know about existential…

Given the vastness of space, it may only be a matter of time before we make contact with intelligent extraterrestrials. But how might an alien civilization react to such a monumental meet-and-greet, and can we possibly know their intentions? Here’s what we might expect.

We know ants form large colonies. In 2002, we realized one specific kind of ant formed supercolonies. And then, in 2010, we learned that they had formed a global colony— and that, without even know it, we had helped them do it.

Siphonophores are groups of creatures that live, connected, as one animal. And they’re incredibly confusing — they all have the same DNA. They can’t separate. They work together to achieve one goal. So why are we supposed to think of them as “colonies,” rather than a single entity?

Space colonization has reached an impasse, for reasons far more fundamental than a lack of money for the Space Shuttle program. There is simply no way humans can travel easily offworld without using massive amounts of rocket fuel to escape the gravity well — and that’s both expensive and environmentally unsustainable.…

It used to be that making cheese meant killing cows. Young cows, specifically—a few days old, at most. The stomach of an unweaned calf produces enzymes that turn liquid milk into good, hard, flavorful cheeses like Parmesan and Cheddar. These enzymes, called rennet, are secreted by mucous membranes that line the calf’s…

This season, Orphan Black introduced a line of genetically male clones to its tale, and with them came a scary new twist in the Orphan Black biology. How scientifically realistic is this weird new development? Well, something like it does happen in the real world — but only with fruit flies, not humans.

Since their inception 60 years ago, satellites have gone on to become an indispensable component of our modern high-tech civilization. But because they’re reliable and practically invisible, we take their existence for granted. Here’s what would happen if all our satellites suddenly just disappeared.

The rules of chess have remained consistent since the early 19th Century, but that doesn’t mean our approach to the game has stayed the same. Here are some intriguing and surprising ways the Game of Kings has changed its shape over the past 150 years.
