What Would Happen If You Actually Walked on the Sun?

We just realised it’s the 20th anniversary of Smash Mouth’s “Walkin’ on the Sun,” a song about not being a normie or giving into ephemeral fads like soul patches. Smash Mouth never did that. “Walkin’ on the Sun” is also the title of the official Smash Mouth biography, which is very good according to the 10 reviews it got on Amazon. Read More >>

What’s the Best Song, According to Science?

Some songs stick to your soul like ectoplasm. Whether you’re at the club or Chuck E. Cheese, sometimes you hear a certain song that brings you back to a moment in your life you’d forgotten. Good music is fun but ephemeral—the best music stays with you forever, sometimes a little too long. Seriously, stop buying Phish t-shirts. Read More >>

What Would Happen If We Blew Up The Moon?

The Moon is the Tango to Earth’s Cash, the Hall to our Oates, the Lennon to our McCartney before they hated each other. Simply put, our planet and the Moon are soul mates: except, of course, if something were to happen to one of them. Like, I don’t know, what if we just blew up the Moon? Read More >>

Why Does Dog Poo Smell Bad to Us but Good to Dogs?

There are some things we can all agree on. For instance: the fact that shit smells bad. There are some contrarians out there—fetishists, middle school class clowns, etc.—but for the most part this issue transcends the usual divisions. Read More >>

Do Dogs Know They’re Good Boys?

In the taxonomy of domestic dogs (Canis lupus familiaris), there are canines of all shapes and sizes, but rest assured, they are all good. A real pup enthusiast knows that within this framework, there are even more intricate strata: there are doggos, puppers, pupperinos, shoobs, shibes, shooberinos, and longboys, for example. While we know all dogs are good boys (and girls), the question remains—do dogs know? Read More >>

Do Insects Enjoy Sex?

As species, we have little in common with bees, fruit flies and beetles. Bugs are so alien to us that it’s hard to know how exactly they experience the world. Do they feel pain? Do they experience pleasure? What is sex like for them? Do they enjoy it in any way—physical or otherwise? Read More >>

What If the Earth Suddenly Turned Flat?

The Earth is a round orb, almost four thousand miles in radius, orbiting a star alongside some other orbs of varying sizes. We’ve taken pictures of it. But some folks don’t believe any evidence presented to them by a government agency. Many have come to the conclusion that the Earth is actually flat. Read More >>

Can Superhuman Mutants Be Living Among Us?

After millions of years of evolution, our species has, like an aging rock band, settled into a comfortable, familiar groove: Your classic bipedal, theory-of-mind-having Homo sapien. Then, there is another class of human. This class of human has spectacular powers, such as mind control or the ability to manipulate electromagnetic waves, and exists mostly in big-budget global superhero franchises, like X-Men (or in mid-budget Ben Stiller-starring cult classics from 1999, like Mystery Men).

Is a Two-Headed Snake One Snake or Two Snakes?

The animal kingdom is stocked with all manner of uncanny creatures, but few are more harrowing and compelling than the two-headed snake. The internet is rife with videos of these oddities wriggling about, and once seen, they’re hard to forget. You begin to ask questions: where do they creatures come from? How do they move? Do they fight over food? And can they sense, on some level, that they’re toting around at least one more head than is strictly necessary? Is the two headed snake one snake — or two? Read More >>

Can You Be Friends With a Bear?

Late last year, a photo of a bear officiating a wedding in Russia went viral. The picture turned out to be fake, but its popularity says something significant about our conception of the species: Despite thousands of years of contrary evidence, and at least one harrowing documentary, human beings still on some level want to view bears as big, cuddly, forest-dwelling dogs.

What’s the Speed of Dark?

The speed of light is one of the most important constants in physics. First measured by Danish astronomer Olaus Roemer in 1676, it was Albert Einstein who realised that light sets an ultimate speed limit for our universe, of 186,000 rip-roaring miles per second. But while the immutability of lightspeed is drilled into physics students at a young age, Einstein’s laws also state that all motion is relative, which got us thinking: what’s the speed of light’s nefarious doppleganger, darkness?

Which Emotions Are the Most Contagious?

We’re all intuitively aware that feelings can be contagious. Your grumpy friend always makes you upset. Your neighbour's giggly baby can cheer you up in minutes. But how, exactly, do humans transfer psychological states between one another, often without noticing? If emotions are communicable like diseases, which are the most contagious? We asked animal behaviourists, evolutionary anthropologists, bioethicists and behavioural scientists to enlighten us. Read More >>
